Bill Seeks to Eliminate Inequities for Child Farmworkers, But Leaves Weak EPA Pesticide Standards in Place

(Beyond Pesticides, March 29, 2024) Last week during National Agriculture Week, U.S. Senator Ben Ray Luján (D-NM) introduced S.4038, the Children’s Act for Responsible Employment and Farm Safety (CARE), aiming to elevate labor standards for young workers in the agricultural sector, as protection from pesticides remains weak. Currently, agriculture stands as the sole industry that permits children—as young as 12 years old—to work without significant limits on their hours of employment outside of school time. This scenario is a reality for hundreds of thousands of children across the U.S., who undertake the demanding tasks of planting, harvesting, processing, and packaging the food produced nationwide.

The CARE Act proposes to align the age and working hour criteria for underage workers in agriculture with those enforced in other sectors. Additionally, the legislation seeks to toughen both civil and criminal penalties for violations of child labor laws and to enhance safeguards for children against the risks of pesticide exposure. It is important to note, however, that the CARE Act would exempt farm-owning families, allowing their children to work on the family farm under the current guidelines.

Exemptions to the Fair Labor Standards Act (FLSA) currently allow children to work unlimited hours, outside of school  hours, in “non-hazardous†agricultural at the age of 12 and child farmworkers may perform may perform any agricultural job, including hazardous work, as of the age of 16. These exemptions apply only to farm labor and are significantly less stringent than laws applying to other sectors. 400,000-500,000 children and youth between the ages of 12-17 are estimated to be working in U.S. agriculture, with children ages 12-13 permitted to work in agriculture outside of school hours. Children ages 14-15 may work in nonagricultural jobs only with strict limitations on time of day and hours per week, but may work in agriculture outside of school hours without any restrictions. S.4038 will make the restrictions for agriculture child labor consistent with non-agriculture labor. Note: The CARE Act would not apply to the children of farmers working on their family farm.

Related legislation, the Fairness for Farm Workers Act (H.R. 4579/S. 2253), introduced in 2023 by U.S. Representative Raúl Grijalva (D-AZ) and U.S. Senator Alex Padilla (D-CA), would amend FLSA to provide overtime and additional minimum wage protections for farm workers. Upon introduction, Senator Padilla said, “It’s past time we correct our nation’s labor laws to include the farm workers who have been unjustly excluded from protections.â€

Disproportionate Impact and “Agricultural Exceptionalismâ€

Creating true equity for farmworkers and specifically farmworker children, advocates point out, would require an overhaul of the laws governing pesticide use and exposure. Current law governing pesticide registration by the U.S. Environmental Protection Agency (EPA) is challenged as note adequately protective. The Food Quality Protection Act (FQPA), which amends the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Federal Food, Drug, and Cosmetic Act (FFDCA), specifically excludes occupational exposure to pesticides from the calculation of cumulative or aggregate health risk from dietary and nondietary exposure. This means that children’s exposure to pesticides while employed in agriculture is excluded when determining the acceptable rates of their overall pesticide exposure. The statutory language of FQPA requires EPA to evaluate all exposure to the residues in food, water, and land of pesticides with a “common mechanism of toxicity†(e.g., families of chemicals like organophosphates and synthetic pyrethroids), but does not require that occupational exposure be included in that calculation.

A report released in January, US pesticide regulation is failing the hardest-hit communities. It’s time to fix it, finds “people of color and low-income communities in the United States and around the world continue to shoulder the societal burden of harmful pollution.†More specifically, the authors state that “ongoing environmental injustice is the disproportionate impact these communities suffer from pesticides, among the most widespread environmental pollutants.†The report, which follows an earlier article (see earlier coverage), documents the long history of “agricultural exceptionalism,†whereby agriculture is specifically excluded from many U.S. labor and occupational safety laws, can exacerbate the well-documented pesticide risks that farmworkers face on the job. 

What is the CARE ACT?

The CARE Act revises FLSA to update agricultural child labor age and work hour standards to match those for non-agricultural child labor, while still maintaining exemptions for family farms, 4-H, and educational or vocational programs that promote agricultural careers.

Key points in the legislation:

  • It preserves and broadens exemptions for children working on family farms, ensuring they can continue to contribute to family agricultural operations.
  • The legislation significantly raises civil and criminal penalties for child labor law violations, with civil penalties going up to $151,380 and penalties for serious violations leading to death or serious injury up to $690,000, both adjusted for inflation. Criminal penalties could reach $750,000 or include up to five years of imprisonment.
  • It eliminates exceptions that currently allow for hand harvest laborers under 16 and reduces children’s exposure to pesticides by repealing certain worker protection standards. Additionally, it extends FLSA child labor protections to independent contractors, requires annual injury reports including workers’ ages to Congress, and mandates improved data sharing between the Department of Labor’s Occupational Safety and Health and Wage and Hour Divisions.
  • The proposed law mandates that, within 90 days after its enactment, the Assistant Secretary of Labor for Occupational Safety and Health and the Administrator of the Wage and Hour Division must sign a memorandum of understanding. This agreement aims to enhance coordination and enforcement between the Occupational Safety and Health Administration (OSHA) and the Department of Labor Wage and Hour Division by sharing information and facilitating enforcement activities. This includes sharing records and reports related to worker injuries, illnesses, or fatalities, especially those involving children under 18. Additionally, the Assistant Secretary of Labor for Occupational Safety and Health is to encourage state agencies with approved state plans to participate in this information sharing. The memorandum is to be modeled after a similar agreement that was effective on May 4, 2023.

Risks to All Farmworkers, Children Uniquely Vulnerable

Children, in particular, face unique risks from pesticide and toxic chemical exposures. Due to their smaller body size, they absorb a higher relative amount of pesticides through the food they consume and the air they breathe. Additionally, children’s developing organ systems make them more vulnerable to the impacts of toxic exposure. Several authoritative bodies, including EPA, the National Academy of Sciences, and the American Public Health Association, have all voiced concerns about the potential dangers that pesticides pose to children. Scientific evidence has shown that pesticide exposure can negatively impact a child’s neurological, respiratory, immune, and endocrine systems, even at low levels. Some pesticides, such as synthetic pyrethroids, organophosphates, and carbamates, are known to cause or exacerbate asthma symptoms.

A specific example of the failure of EPA to protect children and specifically child farmworkers is found in the case of chlorpyrifos, a previously banned organophosphate insecticide under a federal court ruling, only to be overturned on appeal by the agrichemical and conventional agriculture industry. Beyond Pesticides has long reported on the multitude of twists and turns in EPA’s actions on chlorpyrifos, see background and a timeline of developments here. Chlorpyrifos is a dangerous, proven neurotoxicant that has dire impacts on children, making EPA’s action to allow its continued use a failure of both its protective mission and ethics. Further, it is an environmental justice failure, given that risks of exposure fall disproportionately on low-income African American and Latino families, including farmworker families, who are at the greatest risk of harm.

Despite several years of study, the science addressing neurodevelopmental effects [of the insecticide chlorpyrifos] remains unresolved,†as reported in The New York Times. This conclusion contradicts both ample scientific evidence and the agency’s own findings. Beyond Pesticides has repeatedly advocated for a ban on the use of chlorpyrifos because of the grave risks it poses. In 2019, Rep. Nydia Velásquez (D-NY) introduced the Ban Toxic Pesticides Act, H.R.230 to ban the insecticide chlorpyrifos from commerce. “It’s unconscionable for EPA to turn a blind eye as children and workers are exposed to this poison,†Rep. Velázquez said.  “If the EPA won’t do its job when it comes to chlorpyrifos, then Congress needs to act—and do so quickly.†No similar legislation has been introduced in the current Congress.

Current State and Federal Legislation

In 1938, the U.S. Congress enacted FLSA to enhance the welfare of workers, notably by restricting the employment of minors in severe forms of child labor. FLSA exempts certain types of agricultural work, permitting children aged fourteen and above to engage in non-hazardous farm tasks outside school hours. It also allows twelve and thirteen-year-olds to participate in such activities with a parent’s or guardian’s permission. The act specifically identifies eleven agricultural jobs as hazardous, which children under sixteen are prohibited from undertaking. Additionally, there are roles deemed hazardous for minors aged 16 to 18. The Department of Labor is responsible for FLSA’s enforcement.

States may pass their own child labor laws, but FLSA is seen as the “floor.†In other words, if a state law is less restrictive than FLSA, then FLSA will be the standard that employers must follow. If the state law is more restrictive than FLSA, then the state law will be the standard that employers must follow.

As documented in the U.S., according to the Department of Labor’s website, states like Alabama, Delaware, Georgia, Kansas, Kentucky, Louisiana, Maryland, Mississippi, Montana, Nebraska, North Carolina, Oklahoma, Rhode Island, Tennessee, Texas, West Virginia, and Wyoming have largely exempted agricultural labor from their child labor regulations. Meanwhile, California, Hawaii, New Hampshire, Washington, and Wisconsin stipulate that individuals must be 18 to engage in farm work during school hours. Furthermore, 14 states have designated 14 as the minimum age for children to work on farms outside of school hours. 

Federal legislation has been introduced often over many years and finds stiff opposition from big agricultural-industrial interests, including an earlier version of the CARE Act in 2023. U.S. Sen. Cory Booker (D-N.J.) also reintroduced legislation in February 2023 to increase protections against exposure to toxic pesticides. The Protect America’s Children from Toxic Pesticides Act (PACTPA) of 2023 includes a ban on the highly toxic pesticide paraquat, which is known to cause Parkinson’s disease, as well as dangerous organophosphates and neonicotinoids. The legislation addresses foundational weaknesses in federal law and the pesticide registration process that have resulted in U.S. approval of numerous pesticides already banned by many other nations.

More on Disproportionate Impact

The authors of the above-mentioned report on disproportionate harm—Nathan Donley, environmental health science director at the Center for Biological Diversity and Robert Bullard, known as the “Father of Environmental Justice†and executive director of the Robert D. Bullard Center for Environmental and Climate Justice at Texas Southern University in Houston—address the impact on child farmworkers. 

Children remain unprotected:

  • Following recommendations from the National Academy of Sciences, the Food Quality Protection Act of 1996 (FQPA) established a mandate that the EPA further protect children from pesticide harm due to their heightened susceptibility to chemical exposures. This protection came in the form of a 10X safety buffer, reducing allowable exposures to all people from pesticides by tenfold as a way of protecting young children and the developing fetus. Given that children are more susceptible to harm from pesticides and children of color are more likely to be exposed to pesticides, this was widely seen as one way to protect the most vulnerable of at-risk populations.
  • Unfortunately, Congress’s intent regarding protecting young children from pesticides has never been fully realized. The National Research Council found that the EPA only put in place the tenfold child safety factor for five out of 59 pesticides it analyzed, and a larger analysis of more than 400 pesticides by the U.S. Government Accountability Office (GAO) found that only 22% had the full safety factor utilized in approval decisions. A more recent analysis of 47 pesticides similarly found that only a small minority of pesticides that are present in food had any safety buffer incorporated for children.
  • The lack of adequate protections can hit certain communities particularly hard. For instance, over 50% of migrant children in the U.S. have an unmet health need compared to just over 2% of all children living in the U.S. Compounding stressors can significantly increase the sensitivity of children to pesticides and other pollutants. Without added protections, children of color and those in low-income households are more likely to remain unprotected.

While OSHA is responsible for monitoring chemical exposures in various sectors, EPA has yet to implement mandatory biological monitoring for agricultural workers exposed to harmful pesticides. Such monitoring, involving the analysis of blood or urine to confirm exposure levels are not hazardous, is operational for certain pesticides through state-led initiatives in California and Washington. Findings from these programs indicate that harmful physiological effects can occur from pesticide exposure even when applied correctly and without immediate symptoms. Instituting a nationwide policy for biological monitoring, inspired by these state efforts, could mitigate risks for agricultural workers nationwide. This will take a concerted effort that rejects the chemical-by-chemical approach to reform, which at the current pace will not meet the urgency of the existential crises that we face as a nation and globe. The solution lies with proven organic methods to manage agricultural production, land spaces, and buildings without toxic chemicals. Reform legislation in Congress must meet the urgent need to make this a transformational moment.

Solutions to Protect Child Farmworker Safety and Fair Labor Standards

Advocates, including Beyond Pesticides, argue that the “precautionary principle” should be widely adopted across United States regulatory frameworks. This principle suggests a fundamental change in how government regulators approach the approval of activities that could lead to pollution. It encourages asking, “What is the minimum possible harm?” instead of, “What level of harm is acceptable?”  Implementing this approach means setting a more stringent, science-backed threshold for proving a chemical’s safety. It grants regulators the authority to preemptively halt potentially harmful actions when safety is uncertain and promotes a thorough investigation into less harmful alternatives. Although pesticides have adverse effects on child health and development, too little research has examined pesticide exposure among child farmworkers.

For more background on deficiencies in farmworker protection, see Precarious Protection: Analyzing Compliance with Pesticide Regulations for Farmworker Safety.

Consumer food choices have a direct effect on those who grow and harvest food production around the world. This is why food labeled organic is the right choice. Certified organic food eliminates the most hazardous pesticides to which farmworkers are exposed in chemical-intensive agriculture. At the same time, an organic diet eliminates these pesticide residues in food and reduces a number of health threats like diabetes and increases brain function. In addition to mitigating serious health concerns associated with petrochemical pesticides and fertilizers, our decisions at the supermarket not only influence agricultural practices, but have a direct impact on the health and safety of farmworkers and their families. Advocates urge everyone to know where their food comes from and eat organic and fairly traded foods whenever possible and say thank you to those who grow and harvest our food.

Maine Fund to Compensate Farmers for PFAS Contaminated Land Underscores Need for Action

(Beyond Pesticides, March 28, 2024) Last week, Maine Central reported the first application was filed for Maine’s first-in-the nation PFAS (per- and polyfluoroalkyl substances) Fund. This $70 million federal-state Fund to Address PFAS Contamination (PFAS Fund) provides compensation for commercial farmers whose health, business, and land have been impacted by PFAS contamination. A critical component of this fund enables the state to purchase contaminated farmland at fair market, pre-contamination value, which in the state of Maine hovers at approximately $3,729 per acre when including estimated market value of land and buildings, according to newly released data in the 2022 Census of Agriculture. “Maine became the first state to ban sludge recycling and approve a 2030 ban on PFAS in nonessential products,†according to reporting by Maine Central.

The state of Maine has exhibited extraordinary leadership in prioritizing public health, ecosystems, and the environment, setting an example for addressing a widespread contamination problem at the local, state, and national level. However, advocates in Maine are raising warnings after the Maine Department of Environmental Protection, according to reporting by Portland Press Herald, proposed “a compromise plan to regulate the sale of products containing forever chemicals [which] would exempt some federally regulated industries such as the automotive, aeronautical, and defense sectors from [the] 2030 ban on the sale of products that contain forever chemicals, even if a safer chemical alternative is available.†Beyond Pesticides will continue to track updates on this proposed plan as more details emerge. 

Jim Britt, Maine Department of Agriculture, Conservation, and Forestry (DACF) spokesperson, shared in a March 18 press release the expanded funding opportunities through the PFAS Fund, building on the framework of the existing PFAS Response Program: “Commercial farmers who have been impacted by PFAS contamination can now apply for an expanded suite of financial support programs:

  • Administrative Cost Grants: A one-time grant intended to partially compensate commercial farms for time spent on activities common to most farms upon the initial discovery of PFAS contamination.
  • Income Replacement Payments: Commercial farms that have stopped selling some or all products due to PFAS contamination may apply to DACF for up to a total of 24 months of lost income support, adjusted for inflation, while they avail DACFs technical assistance to determine a viable path forward.
  • Technical Assistance / Professional Services: Financial support for professional services to help guide recovery efforts (e.g., business planning).
  • Clean Feed Assistance: Short-term financial support for clean feed when it is necessary for the health and welfare of livestock and when clean feed is not available from the farm.
  • Equipment and Input Cost Grants: Financial support for equipment and related input costs to allow a commercial farm to convert its operations to accommodate new products and production methods.
  • Infrastructure Grants: Financial support for infrastructure projects (permanent physical assets and structures) that will help a commercial farm transition to new products and production methods.
  • Debt Service on Existing Loans: Payments toward loan obligations directly related to farm infrastructure built/installed just prior to the discovery of PFAS contamination.
  • New Loan Assistance: Financial support for costs associated with obtaining new loans.â€

A growing list of state governments and industry actors are moving to phase out and ultimately ban PFAS in consumer products:

  • “Maine, Minnesota, and Washington have given state agencies the authority to ban PFAS in a wide range of products.
  • Twelve states, including California, Colorado, Connecticut, Hawai’i, Maine, Maryland, Minnesota, New York, Oregon, Rhode Island, Vermont, and Washington, have enacted phase-outs of PFAS in food packaging.
  • Eight states, including California, Colorado, Maine, Maryland, Maine, New York, Vermont, and Washington, have adopted restrictions on PFAS in carpets, rugs, and/or aftermarket treatments.
  • Six states, including California, Colorado, Maryland, Minnesota, Oregon, and Washington, are taking action to eliminate PFAS in cosmetics.
  • Twelve states, including California, Colorado, Connecticut, Hawai’i, Illinois, Maine, Maryland, Minnesota, New Hampshire, New York, Vermont, and Washington, have banned the sale of firefighting foam containing PFAS.
  • 32 unique retail chains, [including Burger King, McDonald’s, Starbucks, Sweetgreen, among others,] have committed to eliminating or reducing PFAS in food packaging, textiles and/or other products.â€

Significant documentation and scientific research indicates the adverse health effects of PFAS for humans, wildlife, ecosystems, and environmental justice communities. A 2023 Environmental International study published by the U.S. Geological Survey (USGS) reveals that 45% of U.S. tap water is contaminated with at least one of the more than 12,000 types of PFAS. This percentage is likely to be on the low end, according to USGS Survey authors, given that only 32 of the 12,000 types of PFAS are detectable by their lab tests. The U.S. Environmental Protection Agency (EPA) last year proposed new limits to PFAS levels in drinking water. The urgency of public health implications for PFAS is stark, given that they have been found in water supplies in nearly 3,000 locations in all 50 states and two territories. PFAS chemicals have also been found in human breast milk, umbilical cord blood, deer meat, fish, and beef. One study using data from the National Health and Nutrition Examination Survey (NHANES) found PFAS compounds in 97% of Americans. Studies have suggested a wide range of health effects, including raised cholesterol levels, high blood pressure or pre-eclampsia during pregnancy, and increased risk of kidney cancer. Just as Bayer/Monsanto have faced waves of lawsuits regarding failure to warn liability claims of the severe adverse health impacts on their product labels, industrial chemical companies have faced similar scrutiny in the legal realm. In 2023, DuPont, Chemours, and Corteva agreed to a $1.185 billion dollar settlement with cities and towns across the United States to cover the cost of PFAS remediation and monitoring in public drinking water systems. To learn more about policy action, litigative history, and scientific literature, see the Daily News Archive on PFAS.

Beyond Pesticides is committed to eliminating the use of toxic petrochemical pesticides, including PFAS, by 2032. To realize this goal, we continuously engage grassroots organizers, communities, and cross-cutting movements in actions to contact state legislatures, Congress, and federal agencies. In 2024 alone, there are two ongoing actions to participate in including “Tell Your Delegate to Protect Marylanders from ‘Forever’ PFAS Pesticides†and “Tell Congress to Protect Farmers and the Public from PFAS.â€

Synthetic Turf Fields, Forever Chemicals and the Safer Alternative: Organic Grass

(Beyond Pesticides, March 27, 2024) A preliminary experiment conducted by Public Employees for Environmental Responsibility (PEER) reveals concerning levels of toxic per- and polyfluoroalkyl substances (PFAS) on the skin of soccer players and coaches after playing on artificial turf fields. The Washington Post reported on March 12 on the PEER test results, which found PFAS levels increased on the skin in three out of four participants following soccer matches on artificial turf. In contrast, no similar increase was observed after games on natural grass fields. The presence of PFAS is alarming due to their association with several serious health issues, including cancer, birth defects, and developmental and immune deficiencies, among others.

The U.S. Environmental Protection Agency (EPA) writes that PFAS exposure risks are particularly concerning for young children, who are more susceptible due to their developing bodies and at risk for higher levels of exposure than adults. Known as “forever chemicals” for their persistence in the environment, PFAS continue to accumulate in the human body, posing long-term health risks. Kyla Bennett, PhD, science policy director at PEER and a former scientist and lawyer with EPA, emphasized the need for further research. “Although this study is preliminary, it highlights the potential risk of dermal absorption of PFAS from artificial turf,” Dr. Bennett stated. She also pointed out the significant gap in our understanding of PFAS exposure through skin contact, a potentially major pathway of exposure. Larger scale scientific studies are currently underway; as The Washington Post noted, “Wayne State University researchers are preparing to conduct a study on whether the chemicals found in turf can affect the endocrine system. For more information, please see Beyond Pesticides reporting on PFAS adding to the legacy of persistent toxics hurting generations of people and the environment.

“If the intent was to spread PFAS contamination across the globe, there would be few more effective methods than lacing pesticides with PFAS,†said Dr. Bennett. Her remarks underscore the significant environmental impacts as these chemicals can leach into surrounding surface and groundwater, posing a threat to drinking water sources. In addition, broader systemic impacts are emerging in addition to the direct contamination of water. As Beyond Pesticides reported, PFAS persistence is due to a fluorine–carbon atom bond being among the strongest ever created. PFAS contamination of drinking water, surface and groundwater, waterways, soils, and the food supply, among other resources, is a ubiquitous and concerning contaminant across the globe.

With health risks including developmental and endocrine system disruption, reproductive harm, cancer, and damage to the liver, kidneys, and respiratory system, PFAS presents a chronic danger that demands action. According to Dianne Woelke, a retired nurse and member of Safe Healthy Play Fields, “PFAS chemicals are so toxic that they are measured in parts per trillion,” Ms. Woelke said. “For every 80,000 square feet of plastic turf, there is between one and 38 pounds of various PFAS chemicals.” She further elaborates on the toxicity of the tire crumbs in between the synthetic blades of turf—found to contain over 350 chemicals. “Parents need to be made aware… just because a consumer product has been made for sale does not mean it is safe.â€

States and local communities are taking action

The United States has an estimated 12,000 to 13,000 synthetic turf sports fields, with over a thousand new installations each year. Activists have sparked increased efforts to limit or remove artificial turf from various settings, including schools, parks, and professional sports arenas, spurring states and local governments to take action. New York has banned the sale of artificial turf with PFAS, starting at the end of 2026, and recognizes that recycling artificial turf can be a greenwashing fallacy (see NRDC 2022). Bills prohibiting the purchase of new artificial turf fields in select locations, such as schools, have also been introduced in Massachusetts and Vermont. In addition, California passed a 2023 bill banning the sale of PFAS-containing artificial turf, but it was not signed into law last year by Governor Gavin Newsom, who sought stronger enforcement and signaled that the issue could return in this legislative year. Newsom did allow cities and counties to again ban artificial turf when he signed a new law reversing a previous law preventing, or preempting, local governments from banning artificial turf. As Times of San Diego reported in October 2023, some California cities have already begun moving to prohibit synthetic lawns, including Millbrae in San Mateo County and San Marino in Los Angeles County. “Emerging research is making it clear that artificial turf poses an environmental threat due to its lack of recyclability and presence of toxins such as lead and PFAS,†said state senator Ben Allen, a Redondo Beach Democrat who authored the state bill. With the new law, “Local governments will again be able to regulate artificial turf in a way to both protect our environment in the face of drought and climate change but also by preventing further contribution to our recycling challenges and toxic runoff,†he said.

Organically managed natural grass is an overlooked solution

Beyond Pesticides and local advocates are fighting with a campaign to bring organically maintained natural grass into the ongoing discussions about artificial turf use. Cortney Jansen, a concerned parent from Sunnyvale, California, expressed her views to the Fremont Union High School District regarding this matter. Despite concerns, the district has agreed to replace six fields with new synthetic turf. [A notable conflict of interest, highlighted by the situation in Sunnyvale—the landscape consultant and construction firm engaged to provide impartial advice on turf replacement was the same entity granted a $14.5 million contract to carry out the work. This consultant was initially tasked with evaluating various alternatives for the replacement of 12 artificial turf fields due for removal before reaching their expected lifespan of eight to ten years.]

Testing for PFAS in artificial turf

Testing for PFAS in water is well defined. For an in-depth discussion that explains the science for non-science audience, please see Toxics Use Reduction Institute (TURI) at University of Massachusetts Lowell fact sheet, Per- and Poly-fluoroalkyl Substances (PFAS) in Artificial Turf Carpet. As TURI notes, testing for PFAS presents significant challenges due to the vast number of compounds within this class and their ability to cause adverse effects at very low concentrations. While testing methods for drinking water and wastewater have been developed, there is a lack of standardized guidelines for assessing PFAS in solid materials, such as artificial turf components. One important way to overcome these challenges includes developing techniques for assessing the total concentration of fluorine-containing organic compounds, which do not specifically target PFAS but indicates their presence. The importance of fluorine atoms as a proxy to measure the presence of PFAS is recognized by 20 states and is the subject of Maryland’s proposed HB1190 bill that would ban pesticides that contain PFAS. Read Beyond Pesticides’ call to action here and testimony here.

Does the synthetic turf industry know this and harken back to the tobacco industry’s playbook? In an email to the Washington Post, Melanie Taylor, the president and chief executive of the Synthetic Turf Council (STC), a trade association for the industry, pointed to the tests showing the presence of PFAS in soil. “STC has worked with its members to ensure their products contain no intentionally added PFAS constituents,†Ms. Taylor said. Advocates note that the real explanation for PFAS contaminated soil could be from pesticides containing PFAS commonly used on conventional natural grass turf, the same PFAS containing pesticides that are the subject of Maryland’s proposed ban.

Given the extreme toxicity of PFAS, its alarming ubiquity, its persistence, and the cost of remediating contaminated drinking water, there is an urgent need to do all we can to stop adding it to the environment. As the federal government has been slow to regulate the industry, local residents, and communities have taken up the call to eliminate the use of PFAS. One impactful area that can be addressed at this level is land management. 

A common and dangerous misconception is that the options for community athletic fields are limited to synthetic turf or synthetically managed natural turf. This is a false dichotomy. There is a third option that avoids both sources of PFAS: organically managed natural turf. Organic management practices build soil health, cycle nutrients naturally, enhance turf resiliency, reduce water use, and do not use petrochemical pesticides or fertilizers. The organic alternative is central to a community’s discussion about its residents’ commitment to the elimination of practices and products that are petrochemical-based and the ability of organically managed soils to draw down (sequester) atmospheric carbon as a reasonable price point—even factoring in water and labor costs.

Study Finds Copper Sulfate and Glyphosate in Waterways, Linked to Human and Environmental Hazards

(Beyond Pesticides, March 26, 2024) The authors of a case study in Canale D’Aiedda, Taranto, Italy, published in Scientific Reports, conclude that, “[T]he results of monitoring and modeling activities revealed a chronic risk associated with the presence of Cu [copper] from November to April in several river reaches and acute risk associated to the presence of glyphosate in several reaches mainly in the wet season.† According to the authors, “The most important factor influencing the chronic risk for Cu were the combination of two factors: the high surface runoff and the Cu applications. The most important factor influencing the glyphosate peaks of concentration is the streamflow.â€

The authors of the study measure the flow of pesticide concentrations through the soil and water assessment tool (SWAT). The ecotoxicological data was collected at two stations in Germany that flow into Italy, within the Canale d’Aiedda basin. The streamflow was monitored between August 2017 and December 2019. Out of hundreds of pesticides and six metabolities investigated in this study, “only traces of copper and glyphosate were found.†The authors continue, “The banks and the bed of the river system are almost all covered by concrete. The hydrological regime is natural and intermittent in the upstream part of the basin, while it is almost perennial, in the remaining area, due to the presence of the discharges from three wastewater treatment plants (WWTPs), located in the municipalities of Montemesola, Monteiasi, and San Giorgio Ionico.â€

While the researchers found significant levels of glyphosate and copper in the study area, they also acknowledge the potential gaps in the SWAT model. “The SWAT model performed satisfactory and good for Cu and glyphosate, respectively. However, it underestimated measured concentrations for both compounds,†as the study reports. “This could depend on the fact that SWAT does not simulate the drift loss which occurs during a pesticide application[], it is still unable to spatially reflect the fate of the drifted part of particles explicitly due to oversimplification[]. Other sources of uncertainty, which could have influenced the results, are related to the quality and quantity of measurements (i.e. discrete data instead of continuous data) used for the calibration and to the temporal discrepancy between the calibration of the streamflow and the calibration of the pesticides concentration[]. Similarly, the input data (i.e. application rates of the pesticides), which were derived from regulations or from the safety sheet, could be affected by a large uncertainty and they have had a key role in the modelling pesticides concentrations [].â€

There are years of scientific studies and reporting that indicate the adverse ecological and public health consequences of widespread glyphosate-based herbicide use in agriculture and land management. A 2023 study in Chemosphere points out that glyphosate exhibits strong evidence of genotoxicity, epigenetic alterations (heritable changes in gene expression), oxidative stress, chronic inflammation, endocrine disruption, and disturbs gut microbiota implicated in lymphomagenesis (growth and development of lymphoma). See the Gateway on Pesticide Hazards and Safe Pest Management for more information and analysis of glyphosate harms. The petrochemical pesticide industry faces continuous litigation from victims of pesticide exposure, including Bayer/Monsanto on Roundup Ready. As of 2022, Bayer settled over 100,000 lawsuits on glyphosate/Roundup, paying out approximately $11 billion. The company faces an additional 30,000 lawsuits pending, according to reporting by Forbes. For a full history of litigation see, “Bayer/Monsanto in Roundup/Glyphosate Case Stung with Largest Multi-Billion Dollar Jury Award, Asks States to Stop Litigation.â€

Copper is widely used in agriculture, both conventional and organic for fungal and bacterial diseases in a wide range of crops, including orchards and vegetable production. It is also widely used to treat utility poles throughout communities. Under the Organic Foods Production Act, “The National List [of Allowed a Prohibited Substances] may provide for the use of substances in an organic farming or handling operation that are otherwise prohibited under this title only if†the synthetic allowed materials fit in several categories including copper.

Copper sulfate is widely used in organic rice production to control algae and an invertebrate known as tadpole shrimp. Most of the world transplants rice seedlings into flooded paddies. Dryland rice production eliminates the need for control of tadpoles, which eat the rice seedlings in flooded fields. Ironically, tadpole shrimp are regarded as a biological control for algae. In 2021, the Crops Subcommittee of the National Organic Standards Board (NOSB) acknowledged the following:

It appears that to date there is sufficient evidence to conclude that:

  1. use of copper sulfate in rice fields can cause environmental damage,
  2. alternative seeding practices could eliminate the need for copper sulfate as both algae and tadpole shrimp cease to be problematic once seedlings are established, and
  3. international standards do not allow for spraying of copper sulfate for organic rice production.

Copper sulfate is a toxic pesticide that has documented incidents of adverse impacts on reproductive, kidney, and liver health. A recent study found that copper sulfate has an association with the development of Parkinson’s disease. Studies also found that copper sulfate is moderately toxic to birds, and it is toxic to fish and aquatic organisms. In previous years, Beyond Pesticides has called for expanded research to determine alternatives to copper sulfate and continues to call for its phase-out of organic agriculture. A 2023 study published in Science of the Total Environment identifies a progressive decline among three endpoints: motor skills, cognitive function, and mental health regarding depression. Markedly, individuals living near residential areas or working in occupations with higher exposure to copper sulfate experience a rapid decline in all endpoints.

The NOSB has previously discussed alternative growing systems that would eliminate the need for copper sulfate and made such alternatives a research priority. Copper sulfate is widely used in organic rice production to control algae and an invertebrate known as tadpole shrimp. Most of the world transplants rice seedlings into flooded paddies. Dryland rice production eliminates the need for control of tadpoles, which eat the rice seedlings in flooded fields. Ironically, tadpole shrimp are regarded as a biological control for algae.

Beyond Pesticides encourages the public to engage with the National Organic Standards board to end the use of all toxic petrochemical pesticides. Every six months the NOSB hosts meetings, reviews allowed substances, and continuously updates their review to ensure the integrity of the organic label and the protection of health and the environment.  People are encouraged to see Beyond Pesticides’ Keeping Organic Strong webpage to learn about next month’s NOSB meeting and a link for submitting comments (due April 3, 2024).

Data Supports Need to Transition Away from Plastics and Pesticides with Holistic Strategy

(Beyond Pesticides, March 25, 2024) Because of their widespread infiltration into the environment and the bodies of all organisms, including humans, plastics contamination requires a holistic strategy to protect life— with consideration given to practices and chemical use that reduce or eliminate harm. Pesticides and other toxic chemicals are adsorbed (adhered) to microplastics, resulting in bioaccumulation and widespread contamination. This adds to the complexity of the problem, which is largely ignored by federal regulatory agencies. While most environmental policies attempt to clean up or mitigate health threats, new data reinforces the need to stop the pipeline of hazardous chemicals, wherever possible.

With new data on the harm associated with plastics and related contamination, it becomes urgently necessary for all government agencies to participate in a comprehensive strategy to eliminate plastics and pesticides. Beyond Pesticides points to the evolving science on plastics contamination and their interaction with pesticides as yet another reason to transition to holistic land management systems that take on the challenge of eliminating hazardous chemical use. Organic land management policy creates the holistic systems framework through which plastics can be eliminated.

>> Tell USDA, EPA, and FDA to create strong restrictions on plastics in farming, water, and food.

The human and environmental health implications of plastic and related contamination are becoming increasingly well documented. Scientists are increasingly concerned about the impacts of microplastics—plastic fragments less than 5 mm in size—on a wide range of organisms. Microplastics can cause harmful effects to humans and other organisms through physical entanglement and physical impacts of ingestion. They also act as carriers of toxic chemicals that are adsorbed to their surface. Studies on fish have shown that microplastics and their associated toxic chemicals bioaccumulate, resulting in intestinal damage and changes in metabolism. Microplastics can increase the spread of antibiotic resistance genes in the environment.

Research continues to raise alarms about the hazards associated with the use of plastic, including the microplastic particles that are distributed in alarming amounts throughout the environment and taken up by organisms, including humans. A study published by researchers at Columbia and Rutgers universities in the January 2024 Proceedings of the National Academy of Sciences reports that the average liter of three brands of bottled water in the U.S. contains almost a quarter of a million bits of microplastics, of which 90 percent are at the nanoscale. The other ten percent are slightly larger, at microscale.

Researchers at Norway’s MicroLEACH project published a study that analyzes the components of 50 items in common use—plastic bags, disposable cups, dishwashing gloves, car tire granules, children’s toys and balloons. They found, as in previous studies, that many hazardous chemicals are in the plastics as well as many that could not be identified because they were not listed in the major chemical substance databases. Only 30 percent of the chemical compounds identified in the study were present in two or more products, suggesting that most plastics contain many unidentified chemicals, far beyond the known impurities, metabolites, and degradation products. Further, it suggests that in the environment plastics are chemically reactive and forming new compounds no one has anticipated and whose toxicity is unknown.

In the Columbia/Rutgers study, the researchers checked for seven types of plastic, but they were only able to identify about ten percent of the nanoparticles they found. Polyethylene terephthalate (PET) was a common ingredient, probably because many water bottles are made of it. However, they also found polyamide, polystyrene, polyvinyl chloride, and polymethyl methacrylate. (Tap water also contains microplastics in many places, although in much lower concentrations.) The team found that the number of individual chemical compounds varied wildly among products, ranging from 114 to 2,456, leading them to conclude that “assessing the toxicity of plastic chemicals present in a product based on testing individual target chemicals has limited value.†The Norwegian scientists also exposed cod eggs, embryos and larvae to water containing microplastics. The toxic effects they observed include spinal deformities reminiscent of scoliosis in humans.

In other new studies, out of a total of 257 patients who completed the study, polyethylene was detected in carotid artery plaque of 150 patients (58.4%), with a mean level of 2% of plaque; 31 patients (12.1%) also had measurable amounts of polyvinyl chloride, with a mean level of 0.5% of plaque. Microplastic particles been found in human lungs, blood, feces, and breast milk. They have even shown up in the brain as well as the placenta.

Highly hazardous PFAS (per- and polyfluoroalkyl substances) are leaching out of plastic containers and contaminating food products, according to research published in Environment Technology and Letters. The data confirm the results of prior research focused on the propensity of PFAS to contaminate various pesticide products through the storage containers.

Plastics in Agriculture and Packaging Clog Arteries Raising Rate of Cardiovascular Disease and Stroke

(Beyond Pesticides, March 22, 2024) With long-running efforts to keep organic land management in the forefront of public health and environmental measures to eliminate petrochemical synthetic substances, including pesticides and fertilizers, plastic again emerges as an increasing threat in a study linking microplastics to cardiovascular disease. The study by Italian researchers, published in the March 7 issue of the New England Journal of Medicine, finds an elevated risk factor for heart attack and stroke associated with plastics found in the plaque of the majority of patients’ carotid arteries. A holistic approach to agriculture that embraces principles and values to enhance biodiversity and protect health, the organic system requires that synthetic substances are compatible with that system. In this context, the environmental and public health effects of plastics are increasingly subject to scrutiny as they permeate nearly every aspect of food production, including fields, crops, foods, and food packaging.

Plastics also migrate from other sectors into agriculture via wind and water and are now ubiquitous in every environment. Removing plastics from any ecosystem is extremely problematic, so getting them out of agriculture will be difficult – but necessary, given the accumulating evidence of their toxicity.

Beyond Pesticides continues to push for eliminating plastic use in organic agriculture. The organization is urging the U.S. Department of Agriculture’s National Organic Standards Board (NOSB) to increase its research into ways to accomplish this. The NOSB is accepting online public comments on its policy goals until April 3 this year. In a recent comment to the NOSB, Beyond Pesticides notes that major sources of plastic inputs to agriculture include plastic mulches, compost, and leachate that migrate from landfills into ground and surface water. Beyond Pesticides has identified key issues, available here, and urges the board to take important actions regarding microplastics and compostable materials.

Beyond Pesticides’ comment states that in addition to their direct harm to health, microplastics “also act as carriers of toxic chemicals that are adsorbed to their surface.†For example, many plastics contain additives such as bisphenol A, organotins and phthalates, all known endocrine disrupters, and these can hitch a ride on the plastic particles. The letter continues, “Some studies on fish have shown that microplastics and their associated toxic chemicals bioaccumulate, resulting in intestinal damage and changes in metabolism. Microplastics can increase the spread of antibiotic resistance genes in the environment.†Studies have shown that microplastics migrate into many human tissues, including the lungs, liver, breast milk, urine, blood, and the placenta.

The universal distribution of plastics ensures that they cannot be avoided. Humans and other organisms take up plastics in the form of micro- and nano-particles by inhalation, ingestion, and skin contact every day. Micro-plastics are about the width of a human hair; nano-plastics are much smaller, about twice the width of a DNA strand. Larger pieces of plastic are ground down to these tiny sizes by weathering, temperature, biological processes, and chemical conditions.

Emerging evidence shows that plastics affect many organs and physiological processes. They can influence cellular metabolism, cell signaling, iron transport, and other vital cellular processes. As scientists find closer connections among various systems previously considered separate, such as gut health, mental health, and immune responses, plastics’ effects on cardiovascular health are attracting more scrutiny. Plastics can impair heart function. They can induce several markers of oxidative stress and associated inflammation. Pregnant mice fed microplastics developed disturbed gut microbes and changes in lipid metabolism, including cholesterol levels, which are factors in cardiovascular disease.

The Italian researchers studied a group of 257 hospital patients who had been diagnosed with plaque in their carotid arteries, a major risk factor for heart attack and stroke. Plaque is a sticky goo of cholesterol and fats that narrows arteries. The researchers examined each patient’s plaque for the presence of microplastics. (They added micro- and nano-scale sizes together in their analysis.) They found two types of plastic out of the 11 they looked for: polyethylene (PE) and polyvinyl chloride (PVC), two chemically related compounds used globally in massive quantities. At 36 percent of the global plastics market, PE is the highest-production non-fiber plastic in the world; PVC is third at 12 percent.

More than half of the full group of patients had PE in their plaque; 12 percent had PVC. The team divided their subjects into those with microplastics and those without microplastics and followed both groups for 34 months, tracking their incidence of cardiovascular events. At the end of the study period, the scientists found that the group with microplastics was at “a higher risk of a composite of myocardial infarction, stroke, or death from any cause†than the group without microplastics. The team tested a set of inflammation markers in the plaques, finding sharply higher levels in the group having microplastics in their plaque. They also checked collagen levels in the plaque as an indicator of activity by lymphocytes and macrophages, immune cells with a role in cardiovascular disease development, finding higher levels associated with the microplastics group.

The study results were adjusted to account for age, sex, body mass index, total cholesterol, diabetes, hypertension, and other conditions. The patients with microplastic-laden plaques were younger, more likely to be male, less likely to have hypertension, more likely to be diabetic, and to have heart disease and high cholesterol. They were also more likely to smoke. Thirty of 150 patients with microplastics in their plaque died or had non-fatal cardiovascular events, while only eight out of the 107 patients without microplastics experienced such events. 

Size matters at the scale of these plastic particles. The smaller the particle, the farther it can travel and the more types of tissues it can enter. Nanoplastics are in the size range of viruses, which means they may enter individual cells. The present study’s authors suggest that nanoplastics likely account for the bulk of the plastics in the plaques. In addition, the smaller a particle, the larger its surface area in proportion to its mass. This makes micro- and nanoplastics able to carry relatively high amounts of absorbed chemicals like pesticides, increasing their effects. And more surface area increases the likelihood of chemical reactions with other substances in the environment, so that the microplastics themselves may be more reactive with biochemistry than their larger versions. Nanoscale particles can also cross the blood-brain barrier. These properties have not been comprehensively assessed for their role in health risks, but they are of increasing concern regarding the smallest particle sizes.

It is also dawning on researchers that plastics’ full chemical interactions with biology are only dimly comprehended and not confined to any compound’s disclosed ingredients. Beyond Pesticides’ letter to NOSB cites a Norwegian study finding that “the components of 50 items in common use—plastic bags, disposable cups, dishwashing gloves, car tire granules, children’s toys and balloons…could not be identified because they were not listed in the major chemical substance databases. Only 30 percent of the chemical compounds identified in the study were present in two or more products. This suggests that most plastics contain many unidentified chemicals, far beyond the known impurities, metabolites and degradation products. Further, it suggests that in the environment plastics are chemically reactive and forming new compounds no one has anticipated and whose toxicity is unknown.†This problem applies to micro- and nano-plastics to an even greater degree, partly because of the abovementioned property of increased chemical reactivity with increased surface area at small scales.

A 2017 Science Magazine review titled “Production, use and fate of all plastics ever made†observed that “without a well-designed and tailor-made management strategy for end-of-life plastics, humans are conducting a singular uncontrolled experiment on a global scale, in which billions of metric tons of material will accumulate across all major terrestrial and aquatic ecosystems on the planet.â€

As widely recognized, plastics are a form of fossil fuel, and it is not just its contribution to the climate crisis that is of concern. Their intractable ubiquity makes the urgency of removing plastics to the greatest extent possible from food production systems all the more dire. Plastic production must be cut drastically back, and a way to recover and sequester even the smallest particle sizes must be developed and implemented without delay. Fossil fuels must, from now on, be left in the ground rather than extracted, extruded, and distributed as micro- and nano-scale invaders of the biosphere.

Hazardous Pesticide with Reproductive and Developmental Effects Enters U.S. Food Supply through Imported Food

(Beyond Pesticides, March 21, 2024) Alarming levels of a hazardous pesticide plant growth regulator linked to reproductive and developmental effects, chlormequat, is found in 90% of urine samples in people tested, raising concerns about exposure to a chemical that has never been registered for food use in the U.S. but whose residues are permitted on imported food. Published in the Journal of Exposure Science and Environmental Epidemiology in February 2024 and led by Environmental Working Group toxicologist Alexis Temkin, PhD, a pilot study finds widespread chlormequat exposure to a sampling of people from across the country. U.S. Environmental Protection Agency (EPA) regulations only permit the use of chlormequat on ornamental plants and not food crops grown in the U.S. As explained in the journal article, “In April 2018, the U.S. EPA published acceptable food tolerance levels for chlormequat chloride in imported oat, wheat, barley, and some animal products, which permitted the import of chlormequat into the U.S. food supply.†In 2020, EPA increased the allowable level of chlormequat in food. Then in April 2023, EPA proposed allowing the first-ever U.S. use of chlormequat on barley, oat, triticale (a hybrid of wheat and rye), and wheat. Existing regulatory standards explain the higher detections of the chemical in U.S. residents tested, as observed in the study and pending domestic use allowances will only increase exposure further. Advocates note that this study on one pesticide reflects systemic failures in the regulatory review process. 

Like many other pesticides, exposure to chlormequat raises significant concerns about the potential impact on public health, as animal studies have linked chlormequat to reduced fertility, harm to the reproductive system, and altered fetal growth, including negative impacts on reproduction and post-birth health, and proper weight and bone development. The study notes that published toxicological research has found potential health effects from chlormequat exposure at doses lower than the current regulatory limits set by the EPA and European Food Safety Authority (EFSA). 

Additionally, chlormequat residues are found in over 90% of conventional oat-based products, while organic food products showed minimal contamination. The report argues the necessity for ongoing biomonitoring to assess the potential health impacts of chlormequat exposure at environmentally relevant levels, especially during critical periods such as pregnancy. Advocates point to the chlormequat findings as evidence of the importance of supporting organic agriculture and organic food products as a means of avoiding harmful chemical exposure.

Research findings and methods

This study investigates the presence of chlormequat in urine samples collected from adults in the U.S. between 2017-2023. Study results detect chlormequat in most urine samples, with detection frequencies increasing from 69% in 2017 to 90% in 2023. Food products purchased in the U.S. and U.K. were also tested, with chlormequat found more frequently in U.S. non-organic oat products than wheat. U.K. oat food samples have 15 times higher chlormequat levels than U.S. samples. The study suggests exposure levels may rise further if chlormequat is approved for domestic agricultural use in the U.S. It raises potential health concerns given toxicology studies linking chlormequat exposure to reduced fertility and impacts on fetal growth.

Toxicological effects at doses lower than EPA’s allowed reference dose (and below the safety limit set by the European regulatory agency)

The pervasive presence of chlormequat in the U.S. population and its detection in conventional oat-based and some wheat-based products demand a comprehensive reevaluation of the risks associated with this chemical, which should raise alarm at the EPA’s current consideration of allowing chlormequat to be used in the U.S. on non-organic agricultural products. The report notes, “Additionally, the regulatory thresholds do not consider the adverse effects of mixtures of chemicals that may impact the reproductive system, which have been shown to cause additive or synergistic effects at doses lower than for individual chemical exposures [22], raising concerns about the potential health effects associated with current exposure levels, especially for individuals on the higher end of exposure in general populations of Europe and the U.S.â€

Specifically, the report noted that animal studies showed:

  • Mice and pigs exposed to doses under the EPA’s reference dose (allowed exhibited reduced fertility, harm to the reproductive system, and altered fetal growth.
  • Pregnant mice exposed to a dose equal to the no observed adverse effect level used to set the EPA limit experienced altered fetal growth and metabolic/body composition changes in neonatal mice.

Additionally, the regulatory thresholds do not account for potential additive or synergistic effects from mixtures of chemicals that impact the reproductive system, as some studies have demonstrated.

This raises concerns that the current exposure levels in some populations, especially those with elevated exposures, could still pose health risks. The study argues that the toxicology research suggests a reevaluation of the safety thresholds may be warranted to better protect public health, and expanded biomonitoring is warranted. Beyond Pesticides advocates for consumers to avoid unnecessary exposure by eating organic food and certified organic food products and to support a systemic change to organic and regenerative organic agriculture.

Assessing chlormequat exposure in U.S. food products purchased between 2022 and 2023

To assess whether chlormequat levels detected in U.S. urine samples correspond to potential dietary exposure, analysis was conducted on oat and wheat-based food products acquired in the U.S. during 2022 and 2023. Results found that non-organic oat products contain chlormequat with a median concentration of 104 parts per billion (ppb). This variability could be attributed to differences in product sourcing, including domestic versus Canadian origins (chlormequat is widely used in Canadian grain crops, while not currently allowed in U.S. agriculture), and whether the oats were treated with chlormequat. In contrast, U.K. food samples demonstrated a higher prevalence of chlormequat, especially in wheat-based products like bread, where 90% of samples had detectable chlormequat levels, and in oat products, where levels were over 15 times higher than those found in U.S. samples. Beyond Pesticides reported in 2014 on U.K. contamination of bread supply, when it was found that over 60% of the country’s bread supply was tainted with chlormequat and glyphosate pesticide residues.  

The presence of chlormequat in urine samples prior to 2018 suggests exposure despite the absence of established food tolerance levels for this pesticide in the U.S. The study hypothesizes that such exposure likely resulted from dietary sources, considering chlormequat’s rapid degradation. According to the authors, “These data indicate likely continuous exposure given the short half-life of chlormequat in vivo, with low levels from 2017 to 2022 and higher exposure levels in 2023.†The formation of chlormequat from choline precursors in wheat and egg powder has been observed under the high temperatures used in food processing, leading to concentrations ranging from 5 to 40 ng/g. These findings imply that dietary exposure to chlormequat could stem from its formation during food processing and from imported products treated with chlormequat. Factors such as geographical location, dietary habits, and occupational exposure in environments like greenhouses could influence individual exposure levels.

This research underscores the need for a broader and more varied analysis of processed foods to thoroughly investigate potential dietary sources of chlormequat, especially in individuals with elevated exposure levels. Future research should encompass the examination of historical urine and food samples, alongside dietary and occupational surveys, to provide a comprehensive understanding of chlormequat exposure sources within the U.S. population. Given that chlormequat is presently restricted to imported oat and wheat products in the U.S., with its domestic use on non-organic crops under review by EPA, there is potential for increased chlormequat levels in the food supply and, consequently, higher exposure levels among the U.S. population.

This study constitutes the first biomonitoring of chlormequat presence in the urine of adults in the United States, expanding the scope of monitoring beyond limited research focused on the United Kingdom and Sweden. A comprehensive pesticide biomonitoring effort involving over 1,000 Swedish adolescents from 2000 to 2017 revealed a 100% detection rate for chlormequat, underscoring the widespread use of chlormequat in the UK, European Union (and Canada), and resulting human exposure levels. 

The discernible spike in urinary chlormequat concentrations in 2023, relative to preceding years, is potentially indicative of its recent introduction into the American food chain, a development that coincides with EPA  of permissible chlormequat levels in food in 2018 and an increase in these limits for oats in 2020.

In assessing whether the urinary chlormequat concentrations reflected potential dietary exposure, this research measured chlormequat levels in oat and wheat-based food products available in the U.S. market in 2022 and 2023. Oat products exhibited a higher frequency of chlormequat presence compared to wheat products, with significant variability in chlormequat content among oat-based items, potentially attributable to differences in sourcing of oats from the U.S. versus Canada. The study suggests that exposure to chlormequat predates 2018, prior to the establishment of food tolerance levels in the U.S., hypothesizing that such exposures were likely dietary in nature given chlormequat’s short half-life. The absence of chlormequat monitoring in U.S. food products and historical data complicates this assertion. However, the natural formation of chlormequat from choline precursors under high-temperature conditions typical of food processing has been documented, leading to chlormequat concentrations within a similar specific range. The variability in chlormequat levels observed in food samples, including those from the only organic oat-based product out of eight organic oat products tested, had low levels of chlormequat, aligning with this phenomenon of natural formation, and suggesting dietary exposure as a plausible source of the pre-2023 urinary chlormequat levels. The elevated levels detected in 2023 may result from dietary exposure to naturally occurring chlormequat and the consumption of imported, chlormequat-treated products. What is unequivocal is the widespread use of chlormequat in Canada, the U.K., and the European Union, where, as previously noted, human biomonitoring studies showed the U.K. and Sweden have almost 100% exposure in the population tested. 

Solutions found in buying organic oat and wheat products, supporting organic farming

Organic food products have been found to have zero contact with pesticides unless due to herbicidal drift from other farming operations. The best defense against pesticide exposure is, whenever possible, choosing to purchase and consume organic.

Mexico Ban on Genetically Engineered Corn Imports Spurs Challenge from U.S. and Canada under Trade Agreement

(Beyond Pesticides, March 20, 2024) A report by CBAN unpacks the ecosystem and wildlife health impacts of genetically engineered (GE) corn in the context of Mexico’s 2023 decision to stop its importation into the country. The phase out of genetically modified (GM) corn imports into Mexico was immediately challenged by the U.S. and Canadian governments as a trade violation under the 2020 U.S.-Mexico-Canada Agreement (USMCA), which replaced the North American Free Trade Agreement (NAFTA) as the primary vehicle for North American trade policy. In August 2023, the U.S. Trade Representative set up a dispute settlement panel under USMCA to stop Mexico from going forward with its ban. There has been no public update from the Office of the U.S. Trade Representative as of this writing.

The CBAN report highlights the scientific rationale underpinning Mexico’s decision to “safeguard the integrity of native corn from GM contamination and to protect human health†with this ban. In 2020, Mexico announced a four-year phase-out of the weed killer glyphosate, which along with other petrochemical herbicides is integral to GM corn production. When Mexico’s Minister of the Environment announced the phase-out, he said it is part of an effort to transform the country’s food system to one that is “safer, healthier and more respectful of the environment (más seguro, más sano y respetuoso con el medio ambiente).†The Minister said that Mexico would be looking to Indigenous farming practices as an alternative. In addition to traditional agriculture, Beyond Pesticides points to organic agricultural practices as a systems approach that simultaneously prohibits the use of toxic petrochemical pesticides such as glyphosate and genetically engineered crops.

The CBAN report explains the background on the USMCA trade deal:

“The United States and Canada are challenging the measures in Mexico’s Presidential Decree of February 13, 2023 that pertain to the use of genetically modified [corn]:

  • [A]n immediate ban on the use of GM corn for human consumption (white corn intended for use in dough and tortillas);
  • [T]he revocation of existing GM corn authorizations and a halt to future approvals; and
  • [A] phase-out of the use of GM corn for animal feed and processed food ingredients.

Mexico’s decree also phases out the use of the herbicide glyphosate but this measure is not being challenged by the US and Canada. Mexico already bans the cultivation of GM corn.â€

The USMCA was adopted with the stated goal of creating “a more balanced environment for trade, will support high-paying jobs for Americans, and will grow the North American economy.â€

In deciding to ban GE corn, Mexico compiled a database of scientific studies that document the health impacts to insects, pollinators, and animals fed GE corn, as well as the adverse health impacts of glyphosate on humans. In addition to herbicide-tolerant GE crops, the CBAN report states, “Most GM corn plants are genetically modified to kill insect pests. The GM plants express a toxin from the soil bacteria Bacillus thuringiensis (Bt) that is known to harm the guts of specific types of insects but not others. Farmers have long used Bt as a spray to kill pests but the Bt toxins in GM crops are different from this natural Bt in structure, function, and biological effects.†The report continues, “In fact, peer-reviewed studies across the scientific literature continue to find that Bt toxins in GM plants can harm insects (spiders, wasps, ladybugs, and lacewings, for example) that are not the intended targets.â€

Similar to the threat of pesticide drift is the threat of genetic drift -typically pollen from a GE crop field being carried by wind or pollinators like honey bees, which are known to travel six miles or further. The National Organic Standards Board, in a unanimous vote in the spring of 2012, sent a letter to Secretary of Agriculture Tom Vilsack saying, “We see the potential of contamination by genetically engineered crops as a critical issue for organic agricultural producers and the consumers of their products. There are significant costs to organic producers and handlers associated with preventing this contamination and market loss arising from it.â€Â 

Within Mexico, there is over a decade of judicial and executive actions against the spread of GE and genetically modified crops, as well as the use of toxic petrochemical pesticides. As reported by Beyond Pesticides in 2013: “[A] judge in Mexico issued an injunction against the planting and selling of genetically engineered (GE) corn seed, effective immediately, within the country’s borders. The decision comes nearly two years after the Mexican government temporarily rejected the expansion of GE corn testing, citing the need for more research. The decision prohibits agrichemical biotech companies, including Monsanto, DuPont Pioneer, Syngenta, PHI Mexico, and Dow AgroSciences, from planting or selling GE corn seed in Mexico.†Then in 2020, Mexico announced the phase out of glyphosate from use or importation into the country by 2024. Mexico joins several other nations that have issued bans, including Germany (the country where Bayer was founded), Luxembourg, and Vietnam. See Genetic Engineering for a list of resources regarding state and local action against GE crops and the corresponding section on Daily News.

The U.S. government and corporate agribusinesses have a history of intervening when other countries or advocates in the U.S. move to ban glyphosate use or advance restrictions on genetically engineered or modified crops. Farmers and environmentalists have taken action in an effort to prevent the proliferation of new pesticide products, including Enlist Duo (glyphosate and 2,4 D hybrid with inert ingredients). A 2017 Daily News reported that: “[A] coalition of farmers and environmental and public health organizations filed a lawsuit against the Environmental Protection Agency (EPA) for approving agrochemical giant Dow Chemical’s toxic pesticide combo, Enlist Duo, among the newer more highly toxic pesticide mixtures used in genetically engineered (GE) herbicide-tolerant crops. Comprised of glyphosate and 2,4-D (50% of the mixture in the warfare defoliant Agent Orange), Enlist Duo is typically marketed alongside commercial crops like corn, cotton and soybeans that are engineered to withstand pesticide exposure, leading to problems of resistance and driving the evolution of super weeds.†A 2023 Daily News reported, “British biotechnology company Oxitec is withdrawing its application to release billions of genetically engineered mosquitoes in California, according to a recent update from the California Department of Pesticide Regulation.†EPA approved the us[e of] a nucleic acid—double-stranded RNA (dsRNA)–called “interfering RNA, or RNAi—to silence a gene crucial to the survival of the Colorado Potato Beetle (CPB), the scourge of potato farmers around the world. (See Daily News.)

Beyond Pesticides continues to support advocates who are passionate in our mission statement of abolishing toxic petrochemical pesticides by 2032. In the spirit of human and ecological health, advocates in our network believe that organic land management and farming principles are the primary pathway forward to make these toxic practices obsolete.

UNEP Initiative Aims to Tackle Petrochemical Pesticide Infiltration in Global Majority Nations

(Beyond Pesticides, March 19, 2024) This month the United Nations Environmental Programme (UNEP) announced the creation of a new initiative to combat the health and environmental impacts of toxic petrochemical pesticides in agriculture. Launched by seven countries—Ecuador, India, Kenya, Laos, Philippines, Uruguay, and Vietnam—the Financing Agrochemical Reduction and Management (FARM) Programme is a $379 million initiative that “will realign financial incentives to prevent the use of harmful inputs in food production.†This international cohort aims to phase out the use of “toxic persistent organic pollutants (POPs)—chemicals which don’t break down in the environment and contaminate air, water, and food.†The work of FARM echoes Beyond Pesticides call for the banning of toxic petrochemical pesticides by 2032.

The program will help countries implement their commitment to eliminate POPs and plastics in agriculture. As it is described, “FARM…will support government regulation to phase out POPs-containing agrochemicals and agri-plastics and adopt better management standards, while strengthening banking, insurance and investment criteria to improve the availability of effective pest control, production alternatives and trade in sustainable produce.†The 2001 Stockholm Convention on Persistent Organic Pollutants requires signatories to adopt a range of measures to reduce and, where feasible, eliminate the release of POPs. All FARM members are signatories and most ratified the Convention as of 2006, with Laos being the most recent to ratify in 2013.

“The five-year programme is projected to prevent over 51,000 tons of hazardous pesticides and over 20,000 tons of plastic waste from being released,†according to the latest UNEP press release. “[W]hile avoiding 35,000 tons of carbon dioxide emissions and protecting over 3 million hectares of land from degradation as farms and farmers convert to low-chemical and non-chemical alternatives,†the release continues. FARM is supported by the Global Environmental Facility, UN Development Programme, UN Industrial Development Organization, and the African Development Bank. The goal of FARM is, “for banks and policy-makers to reorient policy and financial resources towards farmers to help them adopt low- and non-chemical alternatives to toxic agrochemicals and facilitate a transition towards better practices.†Beyond Pesticides applauds this important step FARM countries are taking to transition away from pesticide dependency; however advocates reiterate the importance of organic land management principles as an opportunity to adopt a systems change framework rather than a product substitution framework that replaces toxic pesticides with less toxic pesticides. According to the U.S. Environmental Protection Agency (EPA), POPs are “intentionally produced chemicals currently or once used in agriculture, disease control, manufacturing, or industrial processes†and “unintentionally produced chemicals…that result from some industrial processes and from combustion.â€

There are cascading socio-ecological impacts of toxic pesticides, including POPs, that has been widely documented. (See Daily News.) Organochlorine compounds (OCs), including organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), are examples of persistent organic pollutants that cause adverse health impacts to wildlife including humpback whales and pandas. A 2021 study published in Environmental Pollution identifies, among female whale populations, “levels of POPs in blubber are higher in juveniles and subadults than in adults, primarily from the transference of contaminants from the mother to her calf.†The study goes on to report previously unknown adverse health impacts, “including reproductive toxicity, immune dysfunction, and increased susceptibility to disease.†Meanwhile, a 2021 study published in Environmental Pollution found that the “Quinling Panda species [‘the rarest subspecies of giant pandas’] are generally exposed to moderate levels of OC pollution. Higher levels of OCs are present in captive pandas relative to wild pandas. The authors identify PCB and OCP residues as coming from atmospheric transportation. At the same time, the study identifies PCBs as a cancer risk to the pandas, in fact the most notable toxicant with the highest carcinogenic risk index of PCB 126 (the most potent highly toxic industrial byproduct that incites numerous adverse physiological effects).â€

Beyond individual animal species, POPs are emerging in remote ecosystems such as coral reefs and Arctic glaciers, leading to harmful impacts and long-term implications for biodiversity and human health. A 2021 study published in Chemosphere based on coral reefs in the South China Sea, “indicate[d that] 17 of the 22 OCPs are detectable in seawater, and all 22 OCPs are detectable in ambient air samples from the SCS. The most prominent chemicals found in air and water samples are CHLs, HCBs, DDTs, and Drins. Although coastal corals have higher chemical concentrations than offshore species, the chemical composition is similar, with DDT and CHL compounds dominant among tissue samples.†The presence of OCPs in the South China Sea raises serious concerns about the long-term biodiversity impacts as they cause adverse health impacts on animals and humans alike, including “respiratory issues, nervous system disorders, and birth deformities to various common and uncommon cancers.†A 2020 study published in Environmental Science and Technology found that POPs are found to be re-released after bioaccumulating in Arctic ice for decades, exacerbating the potential exposure levels facing marine animals, oceans, and humans as the climate crisis rages on and causes Arctic ice to melt in the coming decades. POPs are also found to have adverse health impacts on humans, including prenatal and early-life exposure leading to chronic illnesses such as developmental disorders to cancer. Persistent organic pollutants can also act like endocrine disruptors and studies link their exposure to female reproductive health disorders such as endometriosis.

As the U.S. EPA states, “Many POPs were widely used during the boom in industrial production after World War II, when thousands of synthetic chemicals were introduced into commercial use.†After the war, the chemical industry looked to commercialize the petrochemical pesticide products for use in pest management and public health. “Just as U.S. industry and public forged an alliance to prepare for World War II, advocates must join with farmers, public health advocates, scientists, and elected officials to demand a new regulatory approach in service of public health, environmental justice, and addressing the climate crisis,†says Max Sano, organic program associate at Beyond Pesticides. Advocates are steadfast in their belief that strengthening federal organic policy and standards will address the proliferation of toxic petrochemical pesticides into soil, waterways, and ecosystems.

Getting Toxics Out of Food Production and Communities Requires Strong Organic Standards

(Beyond Pesticides, March 18, 2024) Comments are due by 11:59 pm EDT on April 3, 2024. Organic standard setting provides for democratic input, full transparency, and continuous improvement. The current public comment period is an important opportunity for the public to engage with the organic rulemaking process to ensure that the National Organic Standards Board (NOSB) and the USDA National Organic Program uphold the values and principles set forth in the Organic Foods Production Act (OFPA). With the threats to health, biodiversity, and climate associated with petrochemical pesticide and fertilizer use in chemical-intensive land management, advocates stress that this is critical time to keep organic strong and continually improving.

Organic maintains a unique place in the food system because of its high standards, public input, inspection system, and enforcement mechanism. But, organic will only grow stronger if the public participates in voicing positions on key issues to the NOSB, a stakeholder advisory board. Beyond Pesticides has identified key issues for the upcoming NOSB meeting below!

The NOSB is receiving written comments from the public on key issues through April 3, 2024. This precedes the upcoming public comment webinar on April 23 and 25 and the deliberative hearing on April 29 through May 1—concerning how organic food is produced. Written comments must be submitted by 11:59 pm EDT on April 3 through the “click-and-submit” form linked or via Regulations.gov.

Sign up for a 3-minute comment to let U.S. Department of Agriculture (USDA) know how important organic is at the webinar by April 3. Links to the virtual comment webinars will be provided approximately one week before the webinars.  

>>Submit your written comment HERE to the National Organic Standard Board by April 3. (See high-priority issues below.)

The NOSB is responsible for guiding USDA in its administration of The Organic Foods Production Act (OFPA), including the materials allowed to be used in organic production and handling. The role of the NOSB is especially important as we depend on organic production to protect our ecosystem, mitigate climate change, and enhance our health. 

A draft meeting agenda is available here.  And a detailed agenda, along with the proposals, are available here. 

Written comments are due by 11:59 pm ET on Wednesday, April 3, 2024, as well as registration for oral comments. Oral comment sign-ups fill up fast! >> Sign up for oral comments here.  

The NOSB plays an important role in bringing the views of organic consumers and producers to bear on USDA, which is not always in sync with organic principles and not giving sufficient support to the critical need to end the use of petrochemical pesticides and fertilizers. There are many important issues on the NOSB agenda this Spring. For a complete discussion, see Keeping Organic Strong and the Spring 2024 Beyond Pesticides’ issues webpage.  

Some of our high-priority issues for the upcoming NOSB meeting: 

  • Reject the petition to allow unspecified “compostable materials†in compost allowed in organic production. Compost made in organic production should use plant and animal waste, and not synthetic materials that could introduce hazardous contaminants like PFAS and microplastics. The current regulations require compost to be made from manure and plant wastes, allowing only synthetics on the National List—that is, those that have specifically been approved by the NOSB and USDA through a public comment process. The only synthetic inputs into compost that are currently allowed are newspaper and other paper. A petition seeks to allow “compost feedstocks†that might include, for example, “compostable†food containers. 

    Both organic and nonorganic farms have been taken out of production because of PFAS contamination, and microplastics can have a synergistic effect with PFAS. Even worse are potential contaminants we don’t know. Current PFAS contamination came from past use of biosolids not known to be a source of “forever chemicals.†Biosolids—fortunately never allowed in organic production—should be a lesson to remember.  
  • Eliminate nonorganic ingredients in processed organic foods as a part of the sunset review. Materials listed in §205.606 in the organic regulations are nonorganic agricultural ingredients that may comprise 5% of organic-labeled processed foods. The intent of the law is to allow restricted nonorganic ingredients (fully disclosed and limited) only when their organic form is not available. However, materials should not remain on §205.606 if they can be supplied organically, and we can now grow virtually anything organically. The Handling Subcommittee needs to ask the question of potential suppliers, “Could you supply the need if the organic form is required?†The materials on §205.606 up for sunset review this year are made from agricultural products that can be supplied organically and thus should be taken off the National List of allowed materials. 
     
  • Ensure that so-called “inert†ingredients in the products used in organic production meet the criteria in OFPA with an NOSB assessment. The NOSB has passed repeated recommendations instructing USDA’s National Organic Program (NOP) to replace the generic listings for “inerts†that may be biologically and chemically active (currently using EPA Lists 3, 4A, and 4B “inertsâ€) with specific substances approved for use. NOP must allocate resources for this project. Recent appropriations have increased for NOP, and some of this money must be used for the evaluation of “inert†ingredients to ensure compliance with the law and to maintain the integrity of the USDA organic label.

    OFPA provides stringent criteria for allowing synthetic materials to be used in organic production. In short, the NOSB must judge—by a supermajority—that the material would not be harmful to human health or the environment, is necessary to the production or handling of agricultural products, and is consistent with organic farming and handling. These criteria have been applied to “active†ingredients, but not to “inert†ingredients, which make up the largest part of pesticide products—up to 90% or more.

    A comparison of the hazards posed by active and “inert†ingredients used in organic production reveals that in seven of 11 categories of harm, more “inerts†than actives pose a hazard. The NOSB and NOP must act on “inerts†NOW and meet OPFA standards.

>> Submit your written comment HERE to the National Organic Standard Board by April 3. 

Comment to NOSB

I would like to address three priority issues in this comment that are of concern to me as a stakeholder in organic.

(1) Reject the petition to allow unspecified “compostable materials†in compost allowed in organic production.
Compost made in organic production should use plant and animal waste, and not synthetic materials that could introduce hazardous contaminants like PFAS and microplastics. The current regulations require compost to be made from manure and plant wastes, allowing only synthetics on the National List—that is, those that have specifically been approved by the NOSB and USDA through a public comment process. The only synthetic inputs into compost that are currently allowed are newspaper and other paper. A petition seeks to allow “compost feedstocks†that might include, for example, “compostable†food containers. 

Both organic and nonorganic farms have been taken out of production because of PFAS contamination, and microplastics can have a synergistic effect with PFAS. Even worse are potential contaminants we don’t know. Current PFAS contamination came from past use of biosolids not known to be a source of “forever chemicals.†Biosolids—fortunately never allowed in organic production—should be a lesson to remember.

(2) Eliminate nonorganic ingredients in processed organic foods as a part of the sunset review.
Materials listed in §205.606 in the organic regulations are nonorganic agricultural ingredients that may comprise 5% of organic-labeled processed foods. The intent of the law is to allow restricted nonorganic ingredients (fully disclosed and limited) only when their organic form is not available. However, materials should not remain on §205.606 if they can be supplied organically, and we can now grow virtually anything organically. The Handling Subcommittee needs to ask the question of potential suppliers, “Could you supply the need if the organic form is required?†The materials on §205.606 up for sunset review this year are made from agricultural products that can be supplied organically and thus should be taken off the National List of allowed materials.

(3) Ensure that so-called “inert†ingredients in the products used in organic production meet the criteria in OFPA with an NOSB assessment.
The NOSB has passed repeated recommendations instructing USDA’s National Organic Program (NOP) to replace the generic listings for “inerts†that may be biologically and chemically active  (currently using EPA Lists 3, 4A, and 4B “inertsâ€) with specific substances approved for use. NOP must allocate resources for this project. Recent appropriations have increased for NOP, and some of this money must be used for the evaluation of “inert†ingredients to ensure compliance with the law and to maintain the integrity of the USDA organic label.

OFPA provides stringent criteria for allowing synthetic materials to be used in organic production. In short, the NOSB must judge—by a supermajority—that the material would not be harmful to human health or the environment, is necessary to the production or handling of agricultural products, and is consistent with organic farming and handling. These criteria have been applied to “active†ingredients, but not to “inert†ingredients, which make up the largest part of pesticide products—up to 90% or more.

A comparison of the hazards posed by active and “inert†ingredients used in organic production reveals that in seven of 11 categories of harm, more “inerts†than actives pose the hazard. The NOSB and NOP must act on “inerts†NOW and meet the standards of the Organic Foods Production Act.

Thank you for your consideration of my comments.

Coral Reefs Under Threat by Glyphosate, Toxic Pesticides

(Beyond Pesticides, March 15, 2024) Toxic pesticides harm all beings and ecosystems, including coral reefs. Large benthic foraminifera (LBF) are single-celled organisms found on reefs that face adverse metabolic impacts after exposure to the weed killer glyphosate and insecticide imidacloprid, according to a study published in Marine Pollution Bulletin. The study found that “even the lowest doses of the fungicide and herbicide caused irreparable damage to the foraminifera and their symbionts.†Beyond Pesticides reiterates our mission of banning toxic petrochemical pesticides by 2032 and that this goal applies to land and water exposure to pesticides. LBFs are typically used as bioindicators for coral health because they are found in substantial quantities and gathering data is not intrusive or damaging to reef health.

Researchers in this study screened three different herbicides (one insecticide, one fungicide, and one herbicide) at three different concentration levels. The experiments were performed in six well-samples, each with 10mL of filtered artificial seawater and a singular LBF. The control plates are artificial seawater and the experimental plates include artificial seawater with the addition of three pesticides (imidacloprid, glyphosate, and tebuconazole). Each pesticide was applied at low, medium, and high doses to measure the direct impacts of each pesticide after dilution in seawater. The research team conducted two different experiments, one based on pulse-amplitude-modulation (PAM) fluorometry and the other to measure isotopic uptake. For the PAM fluorometry experiment the researchers “measured the photosynthetic performance of the photosymbionts [an organism in a photosymbiotic relationship] for two weeks at days 1, 3, 5, 7 and 14 using variable chlorophyll fluorescence imaging of photosystem II (PSII; Imaging PAM Microscopy Version–Walz GmbH; excitation at 620 nm). Measurement of the variable fluorescence over the maximum quantum yield fluorescence (Fv/fm) estimates the efficiency of photosystem II []. Fv/fm serves as a proxy for the vitality of the photosymbionts [] and therefore it can be used as an indicator of the health of the foraminifera themselves [].†In terms of the isotopic uptake experience, “Two-way ANOVAs (level of significance p = 0.05) were run to test if the type of pesticide, the concentration and/or incubation time significantly affected uptake of 15N and 13C, respectively. Significant results were further analyzed for group differences using Tukey’s post hoc test (level of significance p = 0.05).â€

This study differs from existing literature in how the researchers quantified the impact based on amount of pesticide products rather than solely on the individual pesticides that make up the main ingredient of the targeted products. “Roundup© [with the active ingredient glyphosate] only contains 1 % glyphosate, in Pronto©Plus the active substance tebuconazole has 13.6 % and in Confidor© the imidacloprid concentration is 20 %, according to the manufacturer’s information,†says the research team. “Based on that, the concentration of active pesticide substances, which can be found in the environment are not a factor of 10 smaller than ours tested, they are approximately the same concentration or even 10 times higher.†The scientists in this study found that, “the photosynthetic area decreased as the amount of pesticide added increased and as the incubation time increased.†Glyphosate-based Roundup Ready in particular “caused a reduction of the photosynthetic area in all foraminifera…independent of concentration.†The scientists also found that, “Foraminiferal [inorganic carbon] 13C uptake was significantly reduced at the highest pesticide concentration compared to the control (p < 0.001). The herbicide and fungicide showed comparable reductions of 13C uptake (p = 0.945), the reduction caused by the insecticide was less pronounced.â€

Oceans and water advocates continue to remind elected officials that we cannot talk about climate action without talking about oceans and waterways stewardship. Bodhi Patil, a UN-recognized oceans solutionist and co-creator of Ocean Uprise, a global activist accelerator initiative, guides his advocacy with the understanding that ocean health is human health. “Mitigating toxic pollutants, excess fertilizers, pesticides, and chemicals entering upstream water bodies and flowing into downstream reef ecosystems is a direct way to reduce the stressors on critically important coral reefs†says Bodhi. “Improved water quality and reduced water pollution will contribute to their long-term health and climate resiliency. We have to think about the ocean as a being that is connected to all waterways, because she is!â€

Advocates have worked tirelessly to codify ocean rights in a United Nations-recognized framework as the impacts of toxic pesticides continue to impact ocean creatures big and small. In 2023, due to the years of advocacy by people like Bodhi, 193 nations approved the draft version of the High Seas Treaty (also known as Biodiversity Beyond National Jurisdiction), an international framework that establishes universal rights to protect the oceans from harm. To date, 88 countries have signed the treaty and two countries (Chile and Palau) have ratified the treaty in their national legislatures. At least 60 countries must ratify the High Treaty for it to become international law. The exorbitant loss of over 90% of planktonic organisms from the 1940 baseline is analogous to the decline in terrestrial pollinator loss over the past several decades. Additionally, “In its 2017 risk assessment for the most widely used neonicotinoid, imidacloprid, EPA found, ‘[C]oncentrations of imidacloprid detected in streams, rivers, lakes and drainage canals routinely exceed acute and chronic toxicity endpoints derived for freshwater invertebrates.’ The agency evaluated an expanded universe of adverse effects data and finds that acute (short-term) and chronic (long-term) toxicity endpoints are lower (adverse effects beginning at 0.65 μg/L (micrograms per liter)-acute and 0.01 μg/L-chronic effects) than previously established aquatic life benchmarks (adverse effects from 34.5 μg/L-acute and 1.05μg/L-chronic effects).†Beyond Pesticides has reported on the linkage to the climate crisis and toxic petrochemical pesticide use in relation to aquatic organisms, oceans, and water.

Beyond Pesticides acknowledges the intersectional nature of the climate crisis and that pesticide drift and exposure (including glyphosate and imidacloprid) is a problem that applies to both terrestrial and marine environments. To avoid the introduction of toxic pesticides into ecosystems at the place of origin, advocates are calling on strengthening organic standards and providing new incentives to expand the domestic production and consumption of organic foods and products. See Keeping Organic Strong to learn how to engage with the National Organic Standards Board Spring 2024 meeting.

Petrochemical Pesticides, Fertilizers, and Plastics Linked to Dire Health Effects while Alternatives Are Available

 (Beyond Pesticides, March 14, 2024)  A recent review in the New England Journal of Medicine (NEJM) highlights the urgent need to address the widespread chemical pollution stemming from the petrochemical industry, underscoring the dire implications for public health. Tracey Woodruff, PhD, author and professor at the University of California San Francisco (UCSF), emphatically states in an email comment to Beyond Pesticides, “We need to recognize the very real harm that petrochemicals are having on people’s health. Many of these fossil-fuel-based chemicals are endocrine disruptors, meaning they interfere with hormonal systems, and they are part of the disturbing rise in disease.” Beyond Pesticides echoes this concern, noting that endocrine disrupting chemicals (EDCs) include many pesticides and are linked to a plethora of health issues such as infertility, diabetes, cardiovascular diseases, obesity, early puberty, as well as attention deficit hyperactivity disorder (ADHD), Parkinson’s, Alzheimer’s, and childhood and adult cancers.  (See Beyond Pesticides’ Disease database here and news coverage here). The review further calls on the clinical community to advocate for policy changes aimed at mitigating the health threats posed by petrochemical-derived EDCs and climate change. Beyond Pesticides urgently calls for the elimination of petrochemical pesticides and fertilizers and advocates for a systemic shift to organic regenerative agriculture.  This call to action is grounded in the understanding that the petrochemical industry’s growth poses existential threats to climate, human health, and biodiversity.  

Dr. Woodruff’s article adds to a series, “Fossil Fuel Pollution and Climate Change,†that NEJM launched in 2021. The journal joined with more than 200 health journals worldwide in publishing a joint editorial “calling for urgent action to limit greenhouse gas emissions to protect human health, adding to growing demands from around the globe.â€Â 

Highlighting the explosive growth in petrochemical production, including plastics, pesticides, and fertilizers, Dr. Woodruff’s report draws a direct line between these activities and a growing burden of chemical exposure responsible for at least 1.8 million deaths annually. As the demand for oil and gas declines due to the shift toward renewable energy sources, multinational fossil-fuel corporations have ramped up the production of plastics and other petrochemicals. This transition is highlighted in the report as a significant factor driving both climate change and increased exposure to health-impacting chemicals through contaminated air, water, food, and a range of manufactured products (including plastics, pesticides, and consumer goods). This body of work is among numerous studies pointing to the far-reaching effects of endocrine disruption on both humans and wildlife. Endocrine disruptors can cause significant harm even at very low exposure levels, with embryonic and fetal development stages being particularly vulnerable to their adverse effects. The report notes, “Consequently, experts believe there is no risk-free level of exposure to these chemicals across the population.â€Â  The report underscores the omnipresent nature of petrochemical-derived EDCs, noting that national biomonitoring data and epidemiologic studies have detected around 150 chemicals in human bodily fluids, including during pregnancy.  “This represents a fraction of potential EDC exposures, since standard detection technology measures less than 1% of totally chemicals in use,†the authors note.  

Of serious concern is the disproportionate impact on communities of color and low-income communities, contributing to health inequities. While the report sheds light on this disparity, it stops short of delving into the environmental justice issues specific to petrochemical pesticide use, which significantly affects farmworkers and their families (see here and here). While the report focuses on what healthcare clinicians can do to reduce EDC exposures for their patients (and includes a helpful example of an environmental exposure history and suggestions of how patients can protect themselves), Dr. Woodruff acknowledges that “most exposures are beyond individual control†and even when one chemical is removed from consumer products, the result is often a substitution of a similar toxic chemical.  

Regulatory Failure 

After a nearly two decade defiance of a federal mandate to institute pesticide registration requirements for endocrine disruptors, the U.S. Environmental Protection Agency (EPA) accepted public comments until last month on establishing a testing protocol for pesticides. (See here for comprehensive Beyond Pesticide comments). Advocates, including Beyond Pesticides, are criticizing the agency’s proposed evaluation as too narrow. EPA never completed protocol for testing potential endocrine-disrupting pesticides that disrupt the fundamental functioning of organisms, including humans, causing a range of chronic adverse health effects that defy the common misconception (and EPA risk assessment assumption) that dose makes the poison (“a little bit won’t hurt youâ€), when, in fact, minuscule doses (exposure) wreak havoc with biological systems. Beyond Pesticides detailed comments call for EPA to suspend or deny any pesticide registration until the agency has sufficient data to demonstrate no unreasonable adverse endocrine system risk per the mandate in Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended by the 1996 Food Quality Production Act. Under FIFRA, there is an inherent presumption of risk, a pesticide is presumed to pose an unreasonable risk until reliable data demonstrate otherwise. If the agency lacks the data and/or resources to fully evaluate endocrine system risks to human health and wildlife, then the agency is obliged to deny registration of said pesticide. Further, it is not the agency but pesticide registrants that have the burden to demonstrate with adequate data that their products will not pose unreasonable adverse effects, including the inherently presumed endocrine-disrupting effects.  

Beyond Pesticide’s Call for an End to Petrochemical Pesticide and Synthetic Fertilizer Use by 2032 

The petrochemical industries’ growth is a driver of three existential threats: climate, human health, biodiversity. In addition to the petroleum used to produce synthetic pesticides, Beyond Pesticides has reported on the plastic saturation of the planet, including through the use of plastic coating of some synthetic pesticides and fertilizers, as well as treated seeds. The reliance on petroleum-based pesticides, fertilizers, and plastics reveals a deep connection of chemical-intensive agriculture to the climate crisis and biodiversity decline and establishes a vivid contrast to organic agriculture which eschews these inputs.​​  

The plastic problem is vast and complex. A 2022 study in Environmental Science & Technology reports that plastics caused chemical pollution has the potential to “alter vital Earth system processes on which human life depends.â€Â  The inherent “chemically inert” property of plastics, once thought benign, has proven to be a double-edged sword. Under certain conditions, plastics are not benign at all; they can leach toxic chemicals into their surroundings. Moreover, plastics do not easily break down into their constituent compounds after their intended life. The result is a world where microplastics, pieces less than five millimeters in diameter, have suffused every ecosystem, as the Guardian reported from the heights of Everest to the depths of the oceans, and even in Antarctica. These microplastics, along with the toxicants they may carry, have entered the food chain, impacting marine organisms, terrestrial livestock, and humans through multiple exposure routes. 

Rising petrochemical production spells disaster for efforts to curb greenhouse gas emissions and avert climate catastrophe​​.  Agriculture is a major consumer of other plastic products, using them for purposes ranging from mulching to irrigation. The United States alone uses approximately 816 million pounds of agricultural plastics annually, with significant environmental implications due to the lack of recycling policies and the resultant soil contamination that affects crop yield and ecosystem health​​. As Center for International Environmental Law in its December 2022 reissued report, Sowing a Plastic Planet: How Microplastics in Agrochemical Are Affecting  our Soils, Our Food, And Our Future writes, “Non-plastic alternatives already exist for most of the agricultural uses of microplastics (organic and organic regenerative agriculture). Accordingly, there is no justification for allowing the continued use of microplastics in fertilizers and pesticides.â€Â  In response to these and other challenges, the United Nations Food and Agriculture Organization (FAO) and other bodies have advocated for a return to traditional, organic farming practices that eschew synthetic materials in favor of organic mulch materials, cover crops, and nonchemical management strategies. These practices reduce dependence on fossil fuel-based inputs and thus, the negative climate, health, and environmental impacts.  Beyond Pesticides supports the transition to organic regenerative agriculture as a comprehensive solution to the myriad problems posed by chemical and plastic use in farming. Organic agricultural approaches offer numerous benefits over chemical methods, including enhanced safety for people and the environment, improved soil health, a more nutritious and nutrient dense food supply, in many cases, superior yields and and can mitigate the effects of agricultural greenhouse gas (GHG) emissions. As the Rodale Institute notes, conventional farming isn’t just contributing to the climate crisis, organic farming is essential to address it and wrote, “Organic methods can produce competitive yields in good weather and outperform conventional in times of drought or flooding, and organic uses less energy and generates fewer emissions while revitalizing the soil and sequestering carbon.  If we’re going to decrease farming’s impact—and we must decrease farming’s impact—then we need organic. Because farming doesn’t only contribute to climate change; it’s greatly affected by it. And it is getting harder and harder to grow food in extreme weather.â€Â Â 

Solutions to Existential Crises of Climate, Human Health, and Biodiversity 

Beyond Pesticides noted in January 2023 that there is no solution to this wide array of crises that includes continued fossil fuel use. The organization wrote: “While the solutions are in reach, tremendous public action is needed to stop the fossil fuel and agrichemical industries from their short-sighted pursuit of profit at any cost…. Arguments are made that high intensity, industrial chemical agriculture is the only way to feed the world, and fossil fuels are the only way to provide energy. Scientific data has spelled out exactly what we are in for if we continue to endorse these dangerous myths.†With chemicals, like pesticides, long advanced by the synthetic pesticide and fertilizer industry as the answer to feeding the world, the United Nations  Special Rapporteur on the right to food concluded in 2017 that industrialized agriculture has not succeeded in eliminating world hunger, and has only hurt human health and the environment in its wake.  

Beyond Pesticides established the Parks for a Sustainable Future program to assist with the transition to organic land management in communities across the U.S. The organization also strives to maintain the integrity of organic standards through Keeping Organic Strong campaign and historical work to transition agriculture to organic practices. In 2022, Beyond Pesticides sponsored a Climate Change Calls for Phase Out of Fossil Fuels Linked to Petrochemical Pesticides and Fertilizer series of national virtual seminars (with archived videos) covering health, biodiversity, and climate. For more on climate-friendly organic agriculture, see Daily News and the groundbreaking work of the Rodale Institute, as captured in its Farming Systems Trial — 40-Year Report, which shows the efficacy and benefits of organic agriculture. California Certified Organic Farmers Association’s Roadmap to an Organic California provides a policy framework for advancing agricultural programs that combat climate change.

Study Shows Organic Agriculture Mitigates Climate Crisis in Contrast to Conventional Agriculture

(Beyond Pesticides, March 13, 2024) A comprehensive study released in Journal of Cleaner Production in August 2023 identifies the potential for organic agriculture to mitigate the impacts of agricultural greenhouse gas (GHG) emissions in the fight to address the climate crisis. In “The spatial distribution of agricultural emissions in the United States: The role of organic farming in mitigating climate change,†the authors determine that “a one percent increase in total farmland results in a 0.13 percent increase in GHG emissions, while a one percent increase in organic cropland and pasture leads to a decrease in emissions by about 0.06 percent and 0.007 percent, respectively.†This descriptive study affirms the urgency of Beyond Pesticides’ mission to ban toxic petrochemical pesticides by 2032, given the projected adverse impacts that conventional agricultural dependence on these toxic pesticides will continue to have on people, wildlife, and ecosystems.

The study refers to various studies focused on a comparative analysis of conventional to organic farming on energy use, greenhouse gas emissions (GHGe), nutrient leaching, soil quality, and biodiversity. The consensus is that organic farming is more sustainable than conventional agriculture. For example, “[S]everal studies comparing conventional to organic agriculture found that the latter used 10%–70% less energy per unit of land for all analyzed crops.†However, measurements on a meta-analysis of soil quality and biodiversity show “significant variability across studies with 16% of them showing a negative effect of organic farming on species richness.†Drawing on this past research, the authors of this study accomplish what the previous research could not: “provide categorical supporting evidence… for the general expectation that organic farming is more environmentally sustainable than conventional farming.â€

These researchers used U.S. state-level data from 1997 to 2010, excluding the years 1998, 1999, and 2009 due to bad data. Additionally, researchers drew GHGe data from the World Resources Institute, economic data (e.g. “real per capita GDP (in chained 2009 dollars), output share for utilities, manufacturing, oil and natural gas, and transportation†as a percentage of state GDP) from the U.S. Bureau of Economic Analysis, Department of Commerce. Additional data was gathered from the U.S. Department of Transportation’s Federal Highway Administration, the U.S. Department of Agriculture’s Economic Research Service, and the U.S. Census Bureau.

To determine a statistical relationship between GHGe and organic farming in the U.S., the researchers use a model based on the STIRPAT (Stochastic Regression on Population, Affluence, and Technology) approach. Researchers summarize the benefits of this analytical method, “Given the importance of transportation to farming, this would help examine whether the potential environmental benefits of organic food production, if any, are substantial enough to outweigh the environmental harm of transportation output embodied in organic farming.† See Subsection 3.2 under Methods for a full breakdown of the empirical specifications of their methodology.

The spatial distribution (as seen above in Figure 2) of the statistical comparison between conventional and organic agricultural across all fifty states amounts to three overarching findings:

  1. “The spatial distribution of agricultural GHG emissions in the United States is uneven: High-emissions states are concentrated in the Great Plains extending south to NM and the southeastern area of the United States. Meanwhile, low-emissions states are in California and the northeastern region extending to MI in the north and MD in the south.
  2. Agriculture is a significant contributor to GDP within the high-emissions states, but organic agriculture represents only a small proportion of total farmland: The contribution of agriculture to GDP in high-emissions Great Plains states ranges from 1.11% to 5.94%, while organic agriculture as a share of total farmland ranges from 0.02% to 0.33%. In the southeastern states, the contribution of agriculture to GDP ranges from 0.39% to 1.41%, and organic agriculture ranges from 0.003% to 0.005%.
  3. Agriculture has a substantially lower contribution to GDP within low-emissions states, but organic agriculture represents a large proportion of total farmland: The contribution of agriculture to GDP ranges from 0.063% to 0.95%, while organic farming as a share of total farmland ranges from 0.14% to 3.13%.â€

Years of reporting by Beyond Pesticides corroborates the findings in the study that organic agriculture is a monitorable and critical solution to address cascading crises relating to climate change and public health. Rodale Institute’s Farming Systems Trial – 40-Year Report highlights the success of regenerative organic agriculture:

  • Organic systems achieve 3–6 times the profit of conventional production;
  • Yields for the organic approach are competitive with those of conventional systems (after a five-year transition period);
  • Organic yields during stressful drought periods are 40% higher than conventional yields;
  • Organic systems leach no toxic compounds into nearby waterways (unlike pesticide-intensive conventional farming)
  • Organic systems use 45% less energy than conventional agriculture, and
  • Organic systems emit 40% less carbon into the atmosphere.

There are also numerous reports that highlight the threat of toxic petrochemical pesticides and fertilizers to the broader climate crisis. For example, a 2020 study documents the use of synthetic fertilizers as a driver of nitrous oxide (N2O) emissions. This phenomenon is of critical concern to advocates given that, “Growth in nitrous oxide emissions over these last four decades has been considerable, with human-caused release, mostly from fertilizer use on cropland, increasing by 30%. Compared to pre-industrial levels, nitrous oxide levels increased 20% from all sources.†While nitrous oxide emissions only make up 6 percent of total greenhouse gas emissions in the U.S., “the impact of one pound of N2O on warming the atmosphere is 265 times that of one pound of carbon dioxide.†In Sub-Saharan Africa, meanwhile, years of soaring fertilizer costs (for both organic and conventional products) that began with the pandemic and continue with currency fluctuations wracked by geopolitical actions, including the Russia-Ukraine War, prevent many farmers from maintaining soil health to produce agricultural products. The climate crisis is also causing significant harm to bumblebees, according to a 2023 study that adds to research tying together the compounding impacts of extreme temperature fluctuations and toxic insecticide exposure in relation to their physical fitness and pollinating capabilities.

Beyond Pesticides strongly advocates for strengthening organic regulations to ensure the positive impact of organic principles in addressing the compounding ecological, public health, and climate crises. See Keeping Organic Strong as the National Organic Standards Board to find the opportunity to suggest changes to the National Organic Program through public hearings, comment periods, and written testimonials that will open up in April.

Study Shows the Prevalence of Toxic Pesticide Leaching into Groundwater Reserves Is an International Concern

(Beyond Pesticides, March 12, 2024) A study released in Science of the Total Environment unpacks the threat of emerging chemicals of concern (CECs), including toxic pesticides, in the groundwater of Tunisia. Researchers highlight that the impact of pesticide drift and leaching into groundwater reserves is not siloed to the Middle East and North Africa (MENA) region, but a key concern for most industrialized countries, including the United States. Authors of this study build on literature of CECs already conducted in the region that have broader implications for the spillover effects of pesticide regulation in broader contexts. This descriptive study and accompanying Environmental Risk Assessment (ERA) demonstrate the urgency of Beyond Pesticides’ mission to ban toxic petrochemical pesticides by 2032 because of the pervasiveness of toxic residues, be it pesticides, antibiotics, or other substances, from groundwater systems to human bodies.

The researchers performed the tests in thirteen wells in the Grombalia shallow aquifer, an area of northeast Tunisia that feeds into the Wadi El Bay watershed, which is defined as a “high population density [with] intensive agricultural activity [in ‘one of the most polluted areas in Tunisia’].†The researchers gathered data “during two seasons and were analyzed with two high resolution mass spectrometry approaches: target and suspect screening. The latter was screening banned pesticides.†For more information on the suspect screening approach for pesticide analysis, see Subsection 2.4 under the Materials and Methods.

The researchers identified 20 target pesticides in this study: Anabasine, atrazine, bendiocarb, bentranil, carbaryl, carbofuran, DEET, desethylatrazine, desethylterbuthylazine, dimethomorph, fenfuram, imidacloprid, isoproturon, methfuroxam, mexacarbate, propamocarb, propoxur, pyroquilon, spiroxamine, and terbuthylazine. Table 2 delineates the concentrations of the most frequently detected pesticides in groundwater samples, which include DEET, mexacarbate, propoxur, desethylatrazine, and terbuthylazine. The authors are particularity concerned with the presence of “several carbamate insecticides…due to their acute and chronic toxicity.†The main source of carbamate insecticides are from agricultural use, which is not surprising given that the Grombalia region’s economy is mainly based on citrus: “77.3 percent of the irrigated area [in this region] is planted with citrus [].â€

“The most frequently quantified pesticides belong to the family of triazine herbicides and carbamate insecticides. Triazines have been highly used on several agricultural crops. The occurrence of triazine herbicides in groundwater has been found very commonly [] with most likely no potential human-health concerns at the observed levels of detection [],†authors report in Section 3.1.2 on the results and discussion subsection on pesticides. According to the report: “The frequent detection of triazines can also be expressed as a function of their groundwater ubiquity score (GUS) index, used to predict the behavior of pollutants in groundwater. Triazines are the compounds with the highest GUS index and detection frequency, indicating their high leachability. Atrazine and its degradation product desethylatrazine are by far the most abundant herbicides detected in shallow groundwater []. Atrazine was not detected in the sampling sites, while its metabolite desethylatrazine was detected in 13 samples in both sampling campaigns []. Some researchers have shown that pesticide metabolites are often detected in groundwater at higher concentrations compared to parent compounds [] and that their presence can be more toxic than their parents. []†This last line on pesticide metabolites is consistent with findings from numerous studies which demonstrate the relationship between groundwater and pesticide residue exposure and infiltration in the United States, for example, “90 percent of Americans having at least one pesticide biomarker (includes parent compound and metabolites) in their body,†according to the Centers for Disease Control and Prevention.

Beyond the focus on pesticides, the study also documents the occurrence of CECs, which include “commonly prescribed drugs [‘antimicrobials, analgesics, anti-inflammatories’], artificial sweeteners [sucralose], insecticides [fipronil], and UV filters.†Sixty-nine compounds of CECS and one transformation product [metabolites or degradation products of the precursor analyte’] and 20 pesticides were detected per well, “ranging between 43 and 7384 ng L−1 and 7.3 and 80 ng L−1, respectively. The unit ng L-1 refers to one nanogram of a substance per liter of water.

Researchers in this study found it pertinent to study toxic substance exposure in Tunisian groundwater since a vast majority of the population accesses water resources through wells linked to aquifers. A 2023 Gallup poll indicates a record dissatisfaction with water quality across 81 percent of the population, particularly in southern regions of the country. “Industrial waste from phosphate mining—phosphogypsum—has led to spikes in cancer rates, infertility, and miscarriage in the region. Once famed for its thriving marine ecosystems, fish stocks have plummeted. Groundwater has been polluted, with diminishing reserves for households.†One of the reasons these researchers focused on an area in northeast Tunisia was because of the lack of existing data regarding toxic substance residues in groundwater reserves generally.

There is extensive reporting by Beyond Pesticides on the human, wildlife, and ecological health implications of pesticide leaching into groundwater. For instance, marine ecosystems along the U.S. West Coast are threatened by forest management practices that permit the use of pesticides including certain herbicides (indaziflam, hexazinone, and atrazine), fungicides (fluopicolide and pyraclostrobin), and insecticides (bifenthrin and permethrin). In Arizona, the State Auditor General reported deep concern over the insufficient amount of groundwater monitoring for pesticides by the Arizona Department of Environmental Quality between 2017 and 2021 which flew in the face of legal requirements.

Beyond Pesticides continues to call on Secretary of Interior Deb Haaland to expand USGS mapping of pesticide use and monitoring and inform the U.S. Environmental Protection (EPA) Administrator Michael Regan that pesticides shown to contaminate rivers and streams must be banned. The regulation of and rulemaking around pesticide infiltration in groundwater is more complicated in the aftermath of Sackett v. EPA (2023), a Supreme Court case that limited EPA’s authority to protect critical wetland ecosystems through a narrower definition of, “Waters of the United States (WOTUS). In the 5-4 SCOTUS decision, regulation of groundwater (including protections against pesticide residue) was undermined once WOTUS was defined by the language, “continuous surface connection to bodies.â€

Beyond the patchwork of state and national law that impacts water and pesticide regulation, investing in the protection of organic agricultural and land management principles is a critical approach to prevent the overwhelmingly majority of toxic petrochemical pesticides from leaching into groundwater in the first place. Beyond Pesticides affirms the decades of advocacy that went into establishing organic agriculture standards through the Organic Foods Production Act of 1990. This legislation established mechanisms for compliance, oversight, and enforcement of the national List of Allowed and Prohibited Substances to protect the public against toxic pesticides that EPA permits acceptable use in conventional, industrial agriculture. See Keeping Organic Strong as the National Organic Standards Board will offer the public the opportunity to suggest changes to the National Organic Program through public hearings, comment periods, and written testimonials in April.

Take Action: Chemical Mixture Issues in Pesticide Products Elevated by the EPA Inspector General

(Beyond Pesticides, March 11, 2024) Inside a recent disagreement between the Office of the Inspector (OIG) and the U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs (OPP) on the agency’s review of pet flea and tick collars—leading to thousands of deaths and poisonings—is a basic question of the adequacy of pesticide regulation. The disagreement is over the cause of 105,354 incident reports, including 3,000 pet deaths and nearly 900 reports of human injury, and the February 2025 OIG report’s conclusion that “[EPA] has not provided assurance that they can be used without posing unreasonable adverse effects to the environment, including pets.” While the disagreement focuses on a number of EPA process failures, Beyond Pesticides urges that the findings advance the need for the agency to address a key element of chemical mixtures in pesticide products not currently evaluated, potential synergistic effects—the increased toxic potency created by pesticide and chemical combinations not captured by assessing product ingredients individually. 

Key to the dispute is what many see as a foundational failure of EPA to evaluate the effect of pesticide mixtures and full formulations of pesticide end products, a longstanding criticism of the agency’s pesticide registration process, which focuses on pesticide products’ active ingredients. The manufacturer identifies the active ingredient as the compound in the product formulation that kills the target pest—even though the other ingredients (called inerts) may be toxic. The concern stems from two scenarios present with the Seresto collar in which EPA is not evaluating (i) the mixture of chemicals in the product purchased by consumers, including the so-called inert ingredients (other chemical agents to increase performance, such as adjuvants, surfactants, solvents, carriers, etc.) and contaminants (both not disclosed on the product label); and (ii) the effect of the mixture of two or more active ingredients in the pesticide product, which may increase the product’s overall toxicity.

In the case of the Seresto flea and tick collar, there is concern that EPA missed the true toxicity of the product by not fully evaluating whether there is a synergistic effect that increases the product’s overall toxic effect. Seresto contains two active insecticide ingredients—the neurotoxic insecticide flumethrin, and the notorious neonicotinoid imidacloprid with adverse effects on the endocrine system and environment.

As Beyond Pesticides pointed out in 2021, when the pet poisonings and deaths made headlines, a 2012 study found that flumethrin and imidacloprid have a synergistic effect in attacking fleas. However, EPA dismissed or ignored this science, stating in a 2016 EPA bulletin, “The risk of the combination of the two active ingredients, flumethrin and imidacloprid, was not assessed because the two chemicals act in completely different ways.â€

Synergistic effects have been widely reported. For example, Beyond Pesticides has reported that researchers found elevated neurotoxic effects from exposure to the glyphosate/Roundup formulation with the so-called inert ingredient polyethoxylated tallowamine (POEAs), also shown to kill human cells. 

>>Tell EPA to start protecting people and pets from pesticide poisoning. 

Despite all the concerns, at the time the poisoning and deaths of pets made headlines in 2021, the agency defended the product’s registration, telling the media that, despite these incidents, EPA deemed Seresto collars “’eligible for continued registration’ based on best available science, including incident data… No pesticide is completely without harm, but EPA ensures that there are measures on the product label that reduce risk.â€

Overall, the OIG highlights known shortcomings in EPA’s pesticide registration program, including (but not limited to): 

  • Failure to address combined effects of multiple pesticides; 
  • Failure to investigate impacts on pets; 
  • Failure to adopt standard operating procedures and a methodology to determine when pet products may pose unreasonable adverse effects to the environment; 
  • Failure to collect complete incident data that would allow EPA to fully understand the risks and take appropriate action; and 
  • Failure to assure the public of the safety of the products. 

Furthermore, EPA continues to rely on labeling to reduce risk, despite its failure to protect pets, children, farmworkers, pollinators, and biodiversity. Advocates point out that If the labeling is not protecting people, then the agency is not fulfilling its responsibility to protect public health and safety and the pesticide products should not be allowed on the market

>>Tell EPA to start protecting people and pets from pesticide poisoning. 

Letter to EPA

More proof of multiple systemic failures by the U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs (OPP) to protect people and their pets from pesticides was presented in a report of the Office of Inspector General (OIG) report, published on February 29, 2024.

The report, The EPA Needs to Determine Whether Seresto Pet Collars Pose an Unreasonable Risk to Pet Health, concludes that, “The EPA’s response to reported pesticide incidents involving Seresto pet collars has not provided assurance that they can be used without posing unreasonable adverse effects to the environment, including pets.†At the time the animal effects made headlines in 2021, the agency defended the product’s registration, telling the media that, despite these incidents, EPA deemed Seresto collars “‘eligible for continued registration’ based on best available science, including incident data. . . . No pesticide is completely without harm, but EPA ensures that there are measures on the product label that reduce risk.â€â€¯Despite the scathing criticism, EPA maintains the position that it conducted an adequate review of the two active insecticide ingredients in the pet collars— the neurotoxic insecticide flumethrin, and the notorious neonicotinoid imidacloprid with adverse effects on the endocrine system and environment.

The OIG points out that EPA’s handling of the flea and tick collars—implicated in 105,354 incident reports, including 3,000 pet deaths and nearly 900 reports of human injury—highlights known shortcomings in EPA’s pesticide registration program, including (but not limited to):

– Failure to address combined effects of multiple pesticides;

– Failure to investigate impacts on pets;

– Failure to adopt standard operating procedures and a methodology to determine when pet products may pose unreasonable adverse effects to the environment;

– Failure to collect complete incident data that would allow EPA to fully understand the risks and take appropriate action; and

– Failure to assure the public of the safety of the products.

Furthermore, EPA continues to rely on labeling to reduce risk, despite its failure to protect pets, children, farmworkers, pollinators, and biodiversity. When EPA cannot protect against ongoing harm to humans and the biosphere with the labeling it approves on pesticide products, it must remove the pesticide product from the market. When faced with evidence of harm from a pesticide, despite its labeling restrictions and warnings, EPA must take steps to halt its use. 

The deaths and poisonings associated with Seresto animal collars requires EPA to immediately establish the necessary protocol to evaluate full formulations of products it allows on the market for additive and synergistic effects. When will you do this?

Thank you for your consideration.

Study Provides First Combined Assessment of Multiple Classes of Pesticides in Human Blood

(Beyond Pesticides, March 8, 2024) A major problem has vexed pesticide regulators and researchers for decades: Humans and other organisms almost always have multiple pesticides in their bodies, but techniques for assessing their combined effects, or cumulative body burden from multiple chemical classes are not typically available. A new study from Chinese and British researchers provides the first combined assessment of multiple classes of pesticides in human blood. The authors believe they are the first to develop a way to quantify multiple types of pesticides in human serum (clear liquid part of blood) as opposed to urine or from other sample collection methods. This is a tool that authors say is a more accurate way of assessing the real world exposure and ultimately the adverse impact of pesticide use on human health.

The researchers had a small sample of 31 men and 34 pregnant women in Wuxi, China. They chose 73 pesticides and a few of their breakdown products to identify from three categories: fungicides, neonicotinoid insecticides, and triazine herbicides. Their testing protocol confirms their expectation that food—primarily produce—is the major source of pesticide exposures. This result reinforces Beyond Pesticides’ mission of supporting the shift in agriculture to pesticide-free methods and regenerative practices. Eating organic food is the most effective way to reduce the body burden of pesticides.

The researchers detect a total of 40 pesticides and 10 related chemicals in the sample. No sample was free of all pesticides. More than 80 percent contained more than 10 pesticides. The researchers note that this adds to the evidence that pesticides are ubiquitous in human bodies. As Beyond Pesticides often stresses, it defies belief that these chemicals could have no effect on human (and ecosystem) health.

Based on the sampling data, the team calculates each subject’s estimated daily intake (EDI) of each pesticide, adding those together to find a cumulative EDI. They then compare the EDI with acceptable daily intake (ADI) standards for each pesticide set by various countries and international organizations, including the U.S. Environmental Protection Agency (EPA) and the World Health Organization. ADI is an estimate of how much of a substance a person could consume daily over a lifetime without suffering adverse health effects. Then they derive a cumulative hazard quotient (HQ), which is an estimate of the health effects resulting from exposures above the ADI.

Of the three pesticide categories, fungicides occurr most often and at the highest levels. Boscalid, a carbamid compound, is the most common fungicide in the samples. Upon its registration in 2003, EPA described it as “practically nontoxic.†But it inhibits succinate dehydrogenase (SDH) a chemical whose structure and functions, in the words of one review, are highly conserved in “nearly all extant eukaryotesâ€â€”that is, everything but bacteria and their unicellular cousins, the archaea. Therefore, what it does to one organism it may very well do to all (including humans). Studies in zebrafish show unambiguously that boscalid affects central nervous system development and function and glucose metabolism, causes oxidative stress, and disrupts reproductive hormones.

Four of the fungicides are triazoles, which the authors note can cross the blood-brain barrier and infiltrate cerebrospinal fluid. The current study is the first to find them in human serum. Triazoles affect a steroid synthesis pathway in fungi that is the same in humans. Triazoles are known to damage cardiac tissue and trigger oxidative stress in rats.

Simazine is the most common triazine herbicide in the samples. The triazine family includes the notorious endocrine disrupter atrazine; simazine is used for weed control in fruit and nut orchards, berry fields and cornfields, and aquatic environments. EPA regulates simazine according to its similarity to atrazine. It was approved in 1972 for algae control in swimming pools, hot tubs and whirlpools until 1994, when EPA withdrew this registration based on “unacceptable cancer and non-cancer health risks to children and adults.†However, by 2022, EPA declared in a rule establishing tolerances for certain crops that “cancer risk is not a concern and a quantitative cancer risk was not conducted.†Researchers have found effects of simazine on the hypothalamic-pituitary-gonadal axis leading to, for example, “constant estrus [in heat]†and “continuous estrogen stimulation of mammary gland†in female rats. Endocrine disruption is a well-established factor in the development of many cancers.

Neonicotinoids are widely recognized to be neurotoxic to many beneficial insects such as bees as well as humans, but they may also have other harmful effects, including disruption of metabolic functions involving lipids and leading to obesity and cardiovascular disease. A previous study in Wuxi by different researchers identified nine neonicotinoids in human serum along with nine lipids already known to be affected by environmental contaminants, including dioxins, polychlorinated biphenyls, polycyclic aromatic hydrocarbons, and organophosphorus flame retardants. The authors of the current study found eight neonicotinoids in their samples, three of which had not been observed in human serum before. They also observed that, like some fungicides, neonicotinoids can cross the blood-brain barrier.

The authors found that there is a clear linear relationship between maximum residue levels allowed in foods, also called tolerances, and the serum levels of pesticides in their study subjects—the higher the allowable residue in food, the higher the serum level of that pesticide. This means that setting these tolerances lower or eliminating them altogether would go a long way toward reducing pesticide exposures, as would better monitoring and enforcement of such regulations in the U.S., especially on imported foods.

One important aspect of the current study is the identification of numerous troubling pesticides not previously found in human serum, findings that adds to the urgency of further investigation. But the study did not directly demonstrate that any of the pesticides they analyzed are causing adverse health effects. The study’s main significance is that it establishes a method for measuring, comparing, and determining cumulative levels of numerous pesticides in human serum. This method can help determine the extent and severity of those pesticides’ consequences individually and cumulatively.

Perhaps unintentionally, the study also highlights the inadequacy of methods calculating exposures and health hazards using the crude estimates of EDI, ADI, HQ and maximum residue levels/tolerances. These concepts are imprecise almost to the point of “hand waving.†They rest on the assumption that there are some levels of pesticides in the body that are harmless—which, even if true, fails to account for the total risks and hazards presented by the ubiquitous body burdens of multiple pesticides. The most rational course to protect humans and ecosystems from pesticide exposures is to switch agriculture to organic methods as soon as possible.

“Regenerative†Agriculture Still Misses the Mark in Defining a Path to a Livable Future

(Beyond Pesticides, March 7, 2024) As the threats to health, biodiversity, and climate converge in agricultural policy and practices, the question of defining the fundamental changes necessary to reverse these existential crises takes on life-sustaining importance. Despite the existence of an organic community with governing stakeholders (farmers, consumers, conservationists, retailers, processors, inspectors, and scientists) that has evolved over at least seven decades and is codified in the Organic Foods Production Act (OFPA) of 1990, the term “regenerative†is now increasingly being advanced as a loosely defined alternative to the organic standard and label, which is transparent, defined, certified, enforced, and subject to public input. The publication AgFunderNews (AFN) last month published its updated “2024 list of agrifood corporates making regenerative agriculture commitments,†a who’s who of the largest food and agribusiness corporations worldwide. The list includes companies such as ADM, Cargill, Danone, General Mills, Tyson, Unilever, Walmart, and more with commitments to millions of acres in their supply chain practicing “regenerative†agriculture with target dates ranging from 2024 to 2050.

The AFN author reporting on the “regenerative†trend states, “[O]ne big challenge is that ‘regenerative agriculture’ still has no set definition. While that still holds true, the bigger observation in 2024 is the number of companies leaning heavily on sustainability jargon to describe goals. With greenwashing pretty rampant nowadays, it will be important to check beneath the PR-friendly language at the actual acres, dates, practices and prescriptions.â€

Organic advocates point out that even if there was an agreed upon definition that was transparent to the public, the defined standard would require an inspection, certification, and enforcement mechanism that allows for public input and oversight, similar to the policy and structure established for organic claims under OFPA.

In January, Civil Eats reported that the State Innovation Exchange (SiX), a progressive answer to the industry-financed American Legislative Exchange Council (ALEC), organized a two-day workshop with over 30 state legislators from across the nation to provide “legislative approaches to promoting regenerative farming and ranching practices, which [SiX] believes can galvanize support across partisan and rural-urban divides.†How will this compare with the organic statute and its mandate for organic systems plans that are soil-based with prohibitions on synthetic fertilizers, sewage sludge (biosolids), irradiation, excluded methods such as genetically engineered crops, and a national List of Allowed and Prohibited Substances? Is this building on organic standards to improve upon existing practices with more equitable and accessible production methods that meet the existential crises, including the climate crisis? Or, is this a weakening of the existing standards? Beyond Pesticides has advocated that the elevation of organic management practices with incentives and support because of the social good it provides in protecting life and saving resources that now go into treating petrochemical pesticide-induced illness and rebuilding after fires, floods, and mudslides, as well as loss of land.

As reported in Civil Eats, senior agriculture and food systems director at State Innovation Exchange (SiX), Kendra Kimbirauskas, finds it important to provide space for state legislators to “arm [them] with the resources needed to tackle ‘tough decisions’ in their State Houses….and expose them to perspectives outside the typical agriculture lobbying groups on abstruse measures and less-obvious implications of bills.†SiX facilitates a cohort of elected officials and state legislators from 43 states in a subset of their Agriculture and Food Systems program called Cohort for Rural Opportunity and Prosperity (CROP). “SiX connects lawmakers to policy advocates and agriculture-based organizations to share information and strategies in creating more effective policies.â€

With the looming crises, organic advocates acknowledge that providing counternarratives to the petrochemical industry and industrial agriculture interests is important to systems change and “creating effective policies,†so long as it meets the urgency of the moment to protect public and ecological health. On the matter of biodiversity collapse, the United Nation’s (UN’s) Conference of the Parties (COP) to the Convention on Biological Diversity (CBD) stated in the 2022 COP15 meeting.: “Despite ongoing efforts, biodiversity is deteriorating worldwide, and this decline is projected to worsen with business-as-usual. The loss of biodiversity comes at a great cost for human well-being and the global economy.â€Â Beyond Pesticides has documented many aspects of this decline in biodiversity, and the implications for ecosystem, human, and planetary health. Similarly, the 28th United Nations Climate Change Conference of the Parties (COP28) in December 2023 signaled “the eventual end of the oil age.â€Â As reported previously, under organic management, healthy soil can absorb and store 1,000 pounds of carbon per acre foot of soil annually. This translates to about 3,500 pounds of carbon dioxide per acre drawn down from the air and sequestered into organic matter in soil. (It is noteworthy that use of synthetic fertilizers actually compromises the carbon-capture ability of some kinds of terrain, such as salt marshes.) A fact often overlooked by policy makers in generating climate strategies is that carbon-sequestering soil practices are federally mandated in certified organic agriculture.

As reported by Beyond Pesticides in October 2021 before COP26, the use of synthetic fertilizers is a particular and noxious contributor to the rising planetary temperature. This happens largely through these products’ emissions of nitrous oxide, or NOx — another potent greenhouse gas that also pollutes the air and feeds the development of ozone. 

While not necessarily representative of the broader movement, some regenerative agricultural practitioners and their products have been found to fall short of organic standards and open the door to loopholes for toxic pesticide use that undermines the sanctity of alternative agricultural systems compared to the conventional status quo. For instance, “regenerative†agriculture could embrace genetically engineered, herbicide-tolerant crops that require heavy use of herbicides. In 2019, industrial food titan General Mills committed to converting one million acres of farmland to regenerative practices by 2030. Their strategy allows for the transitional use of glyphosate-based herbicides in their regenerative agriculture strategy, which does not align with organic standards of proving that restricted pesticides have not touched land for three years. 

Additionally, a 2019 report by Friends of the Earth indicates the relationship between no-till practices (often analogous to “regenerative†agriculture) and the use of pesticides such as glyphosate: “86 percent of No-Till Farmer readers said they planned to plant Roundup Ready corn in 2017, while 80 percent planned to plant Roundup Ready soybeans, and some 92 percent planned to use glyphosate for weed control.†This connection between no-till, regenerative, agriculture and the application of pesticides is also true in Vermont, where farmers are advised to grow and spray cover crops with the Glyphosate-based herbicide Roundup. “Glyphosate is applied to the [genetically engineered] corn crop as it grows, adding the compound not only to the soil (from where it can migrate to ground or surface waters) but also, because glyphosate is a systemic herbicide, to the whole of the plant that livestock will ultimately eat. Then, farmers are using the herbicide on the same fields again to kill off cover crops once those have grown and served their purposes.†As a result, the application of glyphosate “rose from roughly 13,000 pounds annually in 2009 to nearly 30,000 in 2016,†exacerbating the health risks to nearby waterways and ecosystems.

Based on a wide array of analyses, organic land management as a baseline is crucial to address compounding crises relating to climate change, biodiversity, public health, and economic stability, while eliminating petrochemical pesticide use by 2032. There are examples of regenerative agriculture certifications that take this approach, including Rodale Institute and Regenerative Organic Alliance’s Regenerative Organic Certified (ROC) label. Researchers in California quantified the reduction of total pesticide use in organic and conventional farms, noting that there was a “18–31% likely reduction in spraying of pesticides on organically managed fields compared to conventional, and a 27% likely reduction in use of pesticide products with high acute human toxicity for organic versus conventional fields†from 2013 to 2019. Biodiversity and pollinator health are also shown to be more prevalent on organic versus conventional farms, according to a 2018 Swedish study that corroborates previous studies in 2011 and 2012.

In terms of safety for human consumption, organic farming has also proven to reduce the likelihood of foodborne human pathogens based on data “compar[ing] dung beetle populations, soil bacteria diversity, and feces removal rates on 70 organic and conventional broccoli farm fields.†Additionally, a 2020 Public Health Nutrition study – a first-in-the-nation comparison of pesticide levels in conventional versus organic milk – found that “all conventional, non-organic milk samples have residues of current-use pesticides, antibiotics, and growth hormones not present in organic samples,†including atrazine, permethrin, cypermethrin, chlorpyrifos, diazinon, amoxicillin, sulfamethazine, and sulfathiazole. Legacy pesticides, including ppDDT and ppDDE, were found in both organic and non-organic samples, but these “residue levels remain higher in conventional milk samples than organic.â€

Inspector General Finds Widely Used Flea Collars Still Not Fully Evaluated by EPA 

(Beyond Pesticides, March 6, 2024) With over 2,500 pet deaths and 900 reports of adverse effects to people, an Office of Inspector General (OIG) report, published on February 29, 2024, reveals multiple systemic failures by the U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs (OPP), citing inadequate safety reviews of Seresto pet collars. The report, The EPA Needs to Determine Whether Seresto Pet Collars Pose an Unreasonable Risk to Pet Health, concludes, “The EPA’s response to reported pesticide incidents involving Seresto pet collars has not provided assurance that they can be used without posing unreasonable adverse effects to the environment, including pets.†At the time the animal effects made headlines in 2021, the agency defended the product’s registration, telling the media that, despite these incidents, EPA deemed Seresto collars “‘eligible for continued registration’ based on best available science, including incident data… No pesticide is completely without harm, but EPA ensures that there are measures on the product label that reduce risk.â€â€¯Despite the scathing criticism, EPA maintains the position that it conducted an adequate review of the two active insecticide ingredients in the pet collars—the neurotoxic insecticide flumethrin, and the notorious neonicotinoid imidacloprid—proven to have adverse effects on the endocrine system as environmental contaminants. 

In the report, the OIG states, “Specifically, the OPP [Office of Pesticide Programs] did not conduct domestic animal risk assessments for either flumethrin or imidacloprid as it had committed to do in initial and final work plans for both pesticides. Furthermore, according to a long-tenured EPA scientist we interviewed, the EPA’s 1998 Guideline 870.7200 for companion animal safety studies is inadequate, and the OPP lacks standard operating procedures and a methodology to help determine when pet products may pose unreasonable adverse effects to the environment.†With this statement, the report calls out EPA for its failure to adequately assess the safety of Seresto flea and tick collars, originally formulated by Bayer and now manufactured by Elanco. The OIG demands that EPA, “Issue amended proposed interim registration review decisions for both flumethrin and imidacloprid that include domestic animal risk assessments for flumethrin and imidacloprid; written determinations on whether the Seresto pet collar poses unreasonable adverse effects in pets; and an explanation of how the Office of Pesticide Programs came to its determinations. Allow for public comment by placing these documents in the applicable registration review dockets.†EPA defends its process and points to mitigation measures it adopted and announced in July 2023. The agency says that it was unable to determine the cause of the animal deaths, except for some possible mechanical strangulations that were associated with a failure of the collar’s release mechanism. However, the agency did find some neurological effects and struck an agreement with Elanco to issue label warnings and improve the quality of incident data collected by the manufacturer. 

The New Lede reported, “The (Seresto) collars have been the subject of more than 105,354 incident reports, including the 3,000 pet deaths, more than any other EPA regulated product in history, according to the EPA’s incident database.†The OIG investigation began in response to these and “nearly 900 reports of human pesticide incidents related to the Seresto pet collars†received from 2012 through 2022.  

Synergistic Effects of Flumethrin and Immidacloprid Not Evaluated 

As Beyond Pesticides previously reported, Seresto collars are plastic pet collars embedded with pesticides designed to kill fleas, ticks, and lice by emitting the poisons from the collar; they contain the active ingredients flumethrin and imidacloprid. Flumethrin, a chemical in the pyrethroid class of synthetic neurotoxic insecticides, has been linked repeatedly to neurological issues, such as seizures and learning disabilities in children, to gastrointestinal distress, and to damage to invertebrates, according to EPA’s own analysis  In a March 2021 call to action, Beyond Pesticides reported that a 2012 study found [flumethrin and imidacloprid] have a synergistic effect, meaning they are more toxic together on fleas. However, EPA consistently fails to evaluate synergistic effects of pesticides, a 2016 EPA bulletin concluded: “The risk of the combination of the two active ingredients, flumethrin and imidacloprid, was not assessed because the two chemicals act in completely different ways.†Similarly, as Beyond Pesticides has pointed out repeatedly, EPA does not do an adequate job of evaluating the risks and harms of exposures to multiple pesticide compounds, as well as those of so-called  “inert†or “other†pesticide ingredients that are not disclosed on the product label. 
 
As the OIG report discovered in its findings, EPA demonstrated:  

  • Lack of Adherence to Registration Process: The EPA’s Office of Pesticide Programs (OPP) has failed to adhere to certain aspects of the pesticide registration review process for the active ingredients, flumethrin and imidacloprid, in Seresto collars. Specifically, the OPP did not conduct domestic animal risk assessments as initially planned, as required by their work plans for both pesticides. This failure raises concerns about the agency’s commitment to ensuring the safety of pet products. 
     
  • Inadequate Guidelines and Procedures: The OPP lacks standard operating procedures and a methodology to determine when pet products may pose unreasonable adverse effects to the environment. According to a long-tenured EPA scientist, the agency’s 1998 Guideline 870.7200 for companion animal safety studies is inadequate and described “as a “glaring weakness†that has become publicly obvious with the Seresto pet collar incidents. More efficient, advanced, and accurate methods for ensuring a margin of safety have been developed.â€Â Â   
     
  • Incomplete Incident Data Collection: The EPA has collected incident data related to Seresto pet collars through its Incident Data System (IDS). However, the IDS does not capture all the necessary data for the agency to assess the unreasonable adverse effects of pet products. This incomplete data collection hampers the EPA’s ability to fully understand the risks associated with Seresto collars and take appropriate action. 
     
  • Lack of Public Assurance: The EPA’s lack of action in response to reported incident data and its failure to capture comprehensive data through the IDS does not provide the public with sufficient assurance that Seresto pet collars are safe for use. The agency’s inaction raises concerns about its commitment to protecting the environment and the well-being of pets. 

The OIG report notes, “ [T}he U.S. House of Representatives Committee on Oversight and Government Reform, which is now the Committee on Oversight and Accountability, Subcommittee on Economic and Consumer Policy launched an investigation…in 2022, the subcommittee released a report of its investigation, which outlined the EPA’s awareness of these incidents and the potential harm caused by the collars and the EPA’s own conclusion after an independent review conducted in 2016 that the collars “probably or possibly†caused 45 percent of the reported pet deaths.â€Â 

The measures EPA announced after its July 2023 review include the following: 

  • Adding label warnings on common adverse effects that have been reported, along with instructions to remove the collar if those effects occur and on how to report the incident.  
  • Requiring the registrant to report incident and sales data on an annual basis and provide additional information about incidents whenever possible.  
  • Improving the quality of data reported when receiving reported incidents from consumers. 

The committee’s report also highlighted that the Seresto collar was banned in Canada following an assessment by federal regulators. The assessment concluded that the collar “probably or possibly” caused 77% of reported incidents categorized as “death” or “major” when used on pets. 

OIG Report Recommendations 

The OIG report makes eight recommendations, which include directing the EPA to improve data gathering and update the EPA’s Incident Data System so that it can “adequately assess incident reports and make timely decisions,†implement procedures for how to conduct domestic animal risk assessments, a measurable standard to determine when a pet product poses unreasonable adverse effects, and update EPA’s 1998 Guideline for Companion Animal Safety to align with international standards.  The first OIG recommendation directs the EPA to revise and issue interim registration review decisions for flumethrin and imidacloprid, perform risk assessments for domestic animals and issue written determination of the Seresto pet collar’s safety. It also asks for an account of the decision-making process by the Office of Pesticide Programs and to enable public feedback by including these documents in the relevant review dockets.

Unsurprisingly, the EPA’s Office of Chemical Safety and Pollution Prevention (OCSPP) claimed they had satisfied this recommendation with actions taken on July 13, 2023, implying no further action was necessary. The OIG pointed out that the EPA’s response missed the recommendation intent. The OIG highlighted that the EPA did not use the formal process required for reviewing these products (interim pesticide registration and a domestic animal risk analysis), did not allow for public comments, and did not conclusively determine the safety of the Seresto collars as advised by issuing a determination on whether the Seresto pet collar poses unreasonable adverse effects in pets. This recommendation remains unresolved and the OIG directs EPA to submit “its responses concerning specific actions in process or alternative corrective actions proposed on the recommendation” within 60 days.

EPA’s other substantive response was to point to a February 2023 joint white paper by the EPA and Food and Drug Administration (FDA) titled “A Modern Approach to EPA and FDA Product Oversight,” which discusses moving regulatory jurisdiction over pet collars and roughly 600 other topical pet products from the EPA to the FDA.  

In the absence of real regulatory reform, readers may ask what they can do to keep their pets safe. 

How to Keep Pets Safe: Use Principles of Ecological Pest Management 

For your pet: While keeping your pets and home free of fleas and ticks is important, Beyond Pesticides recommends talking to your veterinarian about treatment options and asking questions about poisoning incidents associated with any product they recommend. Pet owners should vacuum daily during flea season with a strong vacuum cleaner, changing the bag often; groom pets with a flea comb daily, using soapy water to dunk and clean the comb between strokes; bathe pets frequently with soap and water; and restrict pets to a single bed and wash bedding frequently to kill larvae. If you choose to use a flea and tick product on your pet, have it applied by your veterinarian and monitor pets for any signs of an adverse reaction after application. 

At home: Ecological Pest Management emphasizes the broader ecology of pest management and avoiding toxic chemicals unless there are no alternatives. Use Beyond Pesticides’ ManageSafe page to find out how to take a least-toxic approach to issues in the home and garden! 

Grow Organic Lawns and Gardens!  

Create a pesticide-free space for your pet and encourage neighbors to do the same. There are plenty of resources to help! See Beyond Pesticides’ factsheets for information on how to manage a weed-free yard and lawn: Read Your “Weeds”: A Simple Guide to Creating a Healthy Lawn. Fall is the best time to intervene and make your yard free of toxic chemicals. Read our fall lawncare fact sheet, Organic Lawn Care 101, for specific information on how to prime your yard for next year! An organic lawn requires a holistic paradigm shift, not a product-for-product swap. However, if you’re looking for safe products, look at our Products Compatible with Organic Landscape Management, and our campaign, Parks for a Sustainable Future, for hands-on assistance to municipalities nationwide. 

Advocate for Policy Change 

Ultimately, the burden of keeping our pets safe from toxic chemicals should not fall on the public. Cities, counties, states, and the federal government should respond to the body of evidence showing that toxic pesticides are harmful through precautionary regulation and legislation. See our Tools for Change and contact us at [email protected] if you’re ready to join the movement to end the use of petrochemical pesticides and transition to organic!

EPA and Court Allow Violations and Hazards of Weed Killer Dicamba Under Existing Stock Order

(Beyond Pesticides, March 5, 2024) Buried in a court decision in February that determined that the U.S. Environmental Protection Agency (EPA) violated the law in allowing harm associated with the herbicide dicamba’s registration is language that permits the damages to continue through this year’s growing season. The judge’s ruling, deferring to EPA’s interpretation of the existing stock provision in the federal pesticide law, continues a pattern of “existing stock†allowances that permit hazards to continue well after a finding of harm or noncompliance. This process contrasts with the issuance of a product recall, which is typically done when pharmaceuticals are found to violate safety standards.

Despite the finding of dicamba’s harm and EPA’s failure to comply with standards, the continued use of the weed killer through the 2024 growing season is effectively authorized in a decision of the U.S. District Court of Arizona, which vacates the EPA’s 2021 authorization of the use of three over-the-top (OTT) uses of dicamba-based herbicide products. In response, EPA issued an existing stocks order.

EPA’s pattern of allowing the use of existing stocks has long been a concern for public health and environmental advocates, who have called for the discontinuance of use upon findings of elevated risk factors or illegal uses that do not comply with statutory standards. After EPA determined in 1999 that the toxic insecticide, chlorpyrifos, is highly neurotoxic to children, EPA announced in June 2000 an agreement it had reached with Dow AgroSciences that phased out most home uses, but permitted sales to continue through 2001 so that all existing stocks could be sold off. During the existing stock sell-off of chlorpyrifos labeled for home use, no warning was provided to the public and retailers offered discounts to help clear their shelves. Beyond Pesticides in the late 1980s (then the National Coalition Against the Misuse of Pesticides/NCAMP) sued EPA (see The Washington Post and The New York Times) when the agency negotiated an agreement with Velsicol to phase out the use of the insecticide chlordane and allow all existing stocks to be used up. Then the issue was cancer, and the judge in the case found that the additional cancers that would be caused by leaving the chemical in commerce for the phaseout period, including the cost to cancer victims, were unacceptable. On a regulatory level, the judge also found that EPA’s failure to evaluate the harm caused during the phase-out period was a violation of the agency’s responsibility under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). The District Court’s finding was reversed on appeal, but by then, EPA had negotiated a shortened phaseout period and established a recall/buyback program, something the agency rarely does. For a history lesson on the failure of FIFRA, see National Coalition Against the Misuse of Pesticides, et al., Appellees, v. Environmental Protection Agency, et al., Appellants, 867 F.2d 636 (D.C. Cir. 1989).

The current situation with the continued use of dicamba under the existing stock allowance is described by EPA’s Office of Chemical Safety and Pollution Prevention: “This Existing Stocks Order is limited in time and scope, allowing for certain sale, distribution, and use of existing stocks of these formerly-registered dicamba products for the 2024 growing season… EPA has received ample evidence that millions of gallons of OTT dicamba had already entered the channels of trade prior to February 6, 2024. Additionally, most growers have already placed orders for dicamba-tolerant seed for the 2024 growing season and, given the timing of these registrations being vacated, are not able to pivot to another herbicide-tolerant seed and herbicide system.â€

A report by AgWeek outlines how the existing stocks order will impact farmers differently depending on the state. “The products can be sold and used by different dates depending on the state, as follows:

  • Iowa, Illinois and Indiana: Sales through May 13; use through June 12 or V4 growth stage in soybeans or first square growth stage in cotton, whichever comes first.
  • Minnesota: Sales south of Interstate 94 through May 13 and north of I-94 through May 31; use south of I-94 through June 12 and use north of I-94 through June 30.
  • South Dakota: Sales through May 21; use through June 20.
  • Alabama, Arizona, Arkansas, Colorado, Delaware, Florida (excluding Palm Beach County), Georgia, Kansas, Kentucky, Louisiana, Maryland, Michigan, Mississippi, Missouri, Nebraska, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, South Caroline, Tennessee (excluding Wilson County), Texas, Virginia, West Virginia and Wisconsin: Sales for soybeans through May 31 and sales for cotton through June 30; use on soybeans through June 30 and use on cotton through July 30.â€

As Beyond Pesticides has mentioned in a previous Daily News, “Dicamba and other types of herbicide have proven to pose stark adverse health risks to farmworkers and ecosystems. . . For example, there is a strong association between dicamba use and an increased risk of developing various cancers, including liver and intrahepatic bile duct cancer, chronic lymphocytic leukemia, and acute myeloid leukemia. In the Gateway on Pesticide Hazards and Safe Pest Management entry for Dicamba, there is a slew of medical studies detailing adverse health and environmental effects, including neurotoxicity, kidney/liver damage, sensitization/irritation, birth/developmental defects, reproductive damage, and respiratory illnesses. Dicamba has also been proven to have adverse health impacts on wildlife habitats, including the spraying of approximately 1,328 pounds in the National Wildlife Refuge in 2016 alone, impacting bird populations and pollinator species in particular. Dicamba is a poster child of a failed regulatory system that creates ecosystem imbalances by attempting to correct them, considering that the herbicidal drift of this herbicide has proven to lead to antibiotic resistance after testing sublethal traces on bacteria.â€

The District of Arizona, in its ruling, provides leeway for the EPA to employ its powers pursuant to the FIFRA: “The Court notes that in response to vacatur of the 2016, as amended in 2018, OTT dicamba registrations, the EPA cancelled the registrations but allowed use of existing stock. Vacating the registrations poses no greater risk to the environment than leaving it in place because other similar herbicide options are available to replace it in the interim. Threats of noncompliance or that growers will use more dangerous non-OTT dicamba products if these registrations are vacated are weakened by concerns reflected in the 2021 Report that such noncompliance already occurs.†Indeed, Section 6 of FIFRA states, “The [EPA] Administrator may permit the continued sale and use of existing stocks of a pesticide whose registration is suspended or cancelled under this section or section 136a [ ]11, to such extent, under such conditions, and for such uses as the Administrator determines that such sale or use is not inconsistent with the purposes of this subchapter.†[7 U.S.C. § 136d(a)(1)]

As advocates witnessed with dimethyl tetrachloroterephthalate (DCPA), chlordane, methyl iodide, and chlorpyrifos, the use of existing stocks orders enables the continued use of toxic pesticides that the EPA has acknowledged are dangerous to farmworkers, farmers, ecosystems, wildlife, and the general public. Some of these existing stocks orders fail to include a sunset date in which these products are permanently phased out of both production and use.

The routine use of existing stock orders serve as an example of EPA’s commitment to facilitating access to toxic pesticides even after the unacceptable hazards and potential damage associated with their use has been determined. Advocates have challenged the continued marketing of pesticides after EPA has determined that risk criteria are exceeded and without any notice to the public and users. Beyond Pesticides takes the position that these hazards are not “reasonable†under FIFRA, given the availability and profitability of USDA certified organic practices that eliminate the need for toxic petrochemical pesticides like dicamba and chlorpyrifos. In collaboration with our partners, Natural Grocers, Stonyfield Organic, and other supporters, Beyond Pesticides has successfully trained parks and land managers for higher education institutions, cities, and municipalities to adopt organic principles as models for state and federal policy.

Take Action: Federal Food Program Asked to Stop Feeding Children Pesticides that Contribute to Obesity

(Beyond Pesticides, March 4, 2024) With 14.7 million children and adolescents in the U.S. recognized as obese by the Centers for Disease Control and Prevention (CDC) and the established connection with endocrine disrupting contaminants, including many pesticides, Beyond Pesticides is calling on federal food assistance programs to go organic. The problem of childhood obesity is higher in people of color and, as a result, is an environmental justice issue. According to CDC, the prevalence of childhood obesity is “26.2% among Hispanic children, 24.8% among non-Hispanic Black children, 16.6% among non-Hispanic White children, and 9.0% among non-Hispanic Asian children.â€

While childhood obesity is recognized as a serious problem, the National School Lunch Program of the U.S. Department of Agriculture (USDA)—although improved by the Healthy, Hunger-Free Kids Act of 2010—still provides lunches laced with obesogenic pesticides. To take meaningful steps against childhood obesity, school lunches must be organic. The program served 4.9 billion meals in fiscal year 2022 in over 100,000 public and nonprofit schools, grades Pre-Kindergarten-12.

Contrary to popular opinion, the blame for the obesity epidemic cannot be attributed solely to diet and exercise broadly, but relates directly to pesticide and toxic chemical exposures, including residues in food, that may lead to Type 2 diabetes, heart disease, high blood pressure, kidney failure, a breakdown of cartilage and bone within joints, and other metabolic disorders. An increasing body of research shows that exposure to certain pesticides and environmental contaminants initiates various changes in metabolism leading to obesity—not only in the exposed person, but also in offspring. According to medical researchers, obesity “is a complex disease which has reached pandemic dimensions†and multigenerational effects. The prevalence of obesity increased three-fold from 1980 to 2019.

While childhood obesity is recognized as a serious problem, the National School Lunch Program of the U.S. Department of Agriculture (USDA)—although improved by the Healthy, Hunger-Free Kids Act of 2010—still provides lunches laced with obesogenic pesticides. To take meaningful steps against childhood obesity, school lunches must be organic.

>> Tell USDA’s Food and Nutrition Service to require organic school lunches. Tell EPA not to register pesticides that contain obesogens.

The failure of the Environmental Protection Agency (EPA) to prevent exposure to obesogens and carry out its statutory mandate to evaluate endocrine disrupting pesticides, puts the public, especially children, at risk. In addition, EPA does not consider and promote nontoxic and beneficial alternatives, such as organic food production—which the agency could do under its mandate to protect against “unreasonable adverse effects†to people and environment in the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA).

Environmental obesogens are endocrine-disrupting chemicals that “may increase adipose tissue deposition, expand adipocytic size, regulate appetite and satiety, and slow metabolism to induce the occurrence of obesity.†A recent review of the literature finds, “Environmental obesogens have the potential to induce adipogenesis, increase energy storage, and interfere with appetite and homeostasis within the neuroendocrine system, thereby promoting the development of obesity. Since the obesogen hypothesis was proposed in 2006, more than 50 chemicals have been identified as environmental obesogens. Furthermore, the increasing usage of newly developed chemical products has led to the detection of increasing amounts of new contaminants in the environment, which may have obesogenic effects and cause potential risks to human health.â€

The current list of identified environmental obesogens includes pesticide active ingredients such as chlorpyrifos, atrazine, organotins, and triclosan, as well as contaminants and other ingredients that may be found in pesticide products such as dioxins, phthalates, per- and polyfluoroalkyl substances (PFAS), alkylphenols, and polyaromatic hydrocarbons (PAHs). In addition to the effects of a single obesogen, two or more obesogens may have a synergistic effect, as shown by the interaction of tributyltin (TBT) and perfluorooctanesulfonate (PFOS).

>> Tell USDA’s Food and Nutrition Service to require organic school lunches. Tell EPA not to register pesticides that contain obesogens.

Letter to Food and Nutrition Service Deputy Under Secretary Stacy Dean, USDA Secretary Vilsack, and Members of Congress:

Consistent with the mission of the Food and Nutrition Service to end hunger and obesity through the administration of 15 federal nutrition assistance programs including the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), Supplemental Nutrition Assistance Program (SNAP), and school meals, it is important that school lunches be free of chemical obesogens. The only way to ensure this is to require that school lunches be prepared with organic ingredients.

Contrary to popular opinion, the blame for the obesity epidemic cannot be attributed solely to diet broadly, but relates directly to pesticide and toxic chemical exposures, including residues in food, that are known as obesogens and associated with a number of related health conditions— high blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol levels collectively known as the “metabolic syndrome.†Metabolic syndrome increases risk of heart disease, stroke, and type 2 diabetes. Avoiding pesticide exposure is a good way to avoid obesogens, so organic food should be part of every strategy—including school lunch programs—designed to provide healthy nutrition to children.

Childhood obesity is a serious problem in the U.S., leading to a host of health problems in childhood and later in life. Juvenile obesity is highest in Hispanic, African American, and lower income groups, which provides an opportunity for the U.S. Department of Agriculture’s (USDA) school lunch program to have a positive impact.

Environmental obesogens are endocrine-disrupting chemicals that “may increase adipose tissue deposition, expand adipocytic size, regulate appetite and satiety, and slow metabolism to induce the occurrence of obesity.†A recent review of the literature finds, “Environmental obesogens have the potential to induce adipogenesis, increase energy storage, and interfere with appetite and homeostasis within the neuroendocrine system, thereby promoting the development of obesity.

In addition to the effects of a single obesogen, two or more obesogens may have a synergistic effect, as shown by the interaction of tributyltin (TBT) and perfluorooctanesulfonate (PFOS).

The National School Lunch Program (NSLP)—as a federally assisted meal program operating in public and nonprofit private schools and residential childcare institutions to provide “nutritionally balanced, low-cost or free lunches to children each school dayâ€â€”must play a leadership role in removing hazardous chemicals from the meals it feeds to children. In providing free or reduced cost lunches to qualified children, NSLP is an excellent way to ensure that children can receive obesogen-free meals. However, since many pesticides are obesogens, those school lunches must be organic.

Please initiate policy requiring organic school lunches.

Thank you.

Please ensure that pesticide risk assessments include the harms arising from exposure to obesogens. Please also ensure that the baseline against which “benefits†of pesticides are measured is organic agriculture.

Thank you.

Literature Review on Obesogens Highlights the Long-Term Metabolic Impacts of Pesticide Exposure

(Beyond Pesticides, March 1, 2024) A comprehensive research review published in Environment & Health analyzes existing research demonstrating the link between an increase in obesity and the proliferation of synthetic chemicals that “interfere with lipid metabolism.†The study documents over 50 obesogens with high-level human exposure rates, including per- and poly-fluoroalkyl substances (PFASs), phthalates (PAEs), and polybrominated diphenyl ethers (PBDEs), that can lead to lipid metabolism disruption including health impacts on the liver and insulin resistance, among other metabolic conditions such as diabetes, hypertension, cardiovascular disease, and dyslipidemia. Authors in this study highlight the scientific research community’s focus on adipose tissue and the liver, and a need to further explore effects on cardiovascular and kidney health. This anthology of research demonstrates the complexity of the threats associated with toxic pesticides, the severe limitations of their regulatory review, and the failure to consider organic practice and product alternatives that eliminate their use.

Environmental obesogens are chemicals that are proven to have a health impact on metabolic systems relating to obesity. This review evaluates literature, going back to the 2006 obesogen hypothesis, on the metabolic impacts of environmental obesogens, including epidemiologic data, in vitro studies, and bioassays. Researchers scanned Web of Science, PubMed, Google Scholar, and Scopus for research studies with search terms including “environmental obesogens,†“lipid metabolism,†“influencing factors,†and “research approaches.â€

The study dissects numerous influencing factors on long-term adverse health effects from obesogen exposure, including transgenerational effects, windows of susceptibility, gender differences, structure-effect relationships, and dietary habits. Researchers find that exposure to obesogens can “alter the epigenetic programming of germ cells (sperm or egg),†meaning that health impacts from these chemicals can be transferred forward through “multiple generations,†vulnerabilities associated with “windows of susceptibility.†In a multitude of animal studies, exposure to toxic chemicals, substances, and pesticides (e.g. chlorpyrifos, PAEs, dioxins, organotins, flame retardants, BPA and analogues, alkylphenols, PFASs, food additives, and heavy metals) in earlier stages of life can lead to health issues when their parent is exposed to chemicals. For example, bis(2-exthylexyl) phthalate (DEHP) “was found to cause long-term disturbance in the glucose homeostasis of [‘Wistar rats’] offspring,†leading to an increase in visceral fat and overall body weight. The review also finds distinctions in lipid metabolic impacts between men and women: “Women typically exhibit a body fat percentage that is approximately 10% higher than that of men.†Gender differences in obesogenic effects are important to track, given the distinction in regulatory pathways impacted by endocrine disruptors in lipid metabolism for men and women.

The molecular structure of the obesogens, be they isomers, stereoisomers, or analogues, can “produce significant variations in their [health] effects, requiring further experimental verification,†however, much more research is needed to be done to increase understanding. Dietary habits, particularly high-fat diets of processed food products, represent the most significant source of exposure to obesogens. “The gut microbiota plays a vital role in the development of obesity,†the authors report. “The composition of the gut microbiota is highly dynamic and can be rapidly and substantially altered by diet and other environmental factors.†Beyond Pesticides tracks scientific studies that corroborate this finding, underscoring the health implications of switching to organic food, including the reduction of glyphosate residues and urinary organophosphate pesticide metabolites.

Obesity is an international health problem. Without intervention, more than half the global population will be living with overweight or obesity problems by 2035, according to the World Obesity Federation. The World Health Organization in 2021 estimated that worldwide obesity has tripled since 1975. Meanwhile, during this same period there has been the introduction of hundreds of petrochemical-based pesticides with the promise of increased food production and pest protection that can be achieved with nontoxic practices.

Beyond Pesticides has discussed extensively the impact of pesticides on public health, as well as opportunities to safeguard yourself and your loved ones from their health impacts. As a keynote speaker at Beyond Pesticides’ 36th National Pesticide Forum, “Organic Neighborhoods: For healthy children, families, and ecology,†Bruce Blumberg, PhD broke down the impacts of prenatal obesogens in the session Cutting Edge Science. “In the obesogen-exposed animals, this structure is disturbed, and that leads to heritable changes in which genes are expressed. This altered structure is inherited, and that leads us to get this leptin-resistant thrifty phenotype four generations later, as published in Ancestral perinatal obesogen exposure results in a transgenerational thrifty phenotype in mice.†There are several aspects of obesogens that scientists are still determining, including the number of obesogens and the degree to which prenatal exposure alters adult phenotype from babies as they grow up from ancestors who have intergenerational interactions with obesogens. There is also a study that describes associations between type 2 diabetes, obesity, and pesticide exposure, specifically β-Hexachlorocyclohexane (β-BHC) and oxadiazon.

What scientists do know are the links between health impacts, toxic pesticide exposure, and healthy alternatives. In 2018, researchers presented the following recommendations on how to avoid exposure to obesogens to the European Society for Endocrinology in Barcelona:

  • “Choosing fresh food over processed products with long lists of ingredients on the label – the longer the list, the more likely the product is to contain obesogens
  • Buying fruit and vegetables produced without pesticides, such as certified organic or local pesticide-free products.
  • Reducing the use of plastic, especially when heating or storing food. Instead, use glass or aluminum containers for your food and drinks.
  • Removing shoes when entering the house to avoid bringing in contaminants in the sole of shoes.
  • Vacuuming often, using high-efficiency particulate air (HEPA) filters and dust your house frequently using a damp cloth.
  • Removing or minimizing carpet at home or work, as they tend to accumulate more dust.
  • Avoiding cleaning products when possible or choose those that do not contain obesogens.â€

Beyond Pesticides has a variety of resources and information to empower consumers with the tools to protect their well-being and opportunities to advocate for the mission to eliminate petrochemical pesticides in the next decade. An effective way to avoid obesogen exposure is purchasing organic food. See Eating With A Conscience and Feeding Your Family Organic…Affordably on strategies for more information.

Oregon Is the Latest State to Step In and Ban Widely Used Neurotoxic Pesticide, Chlorpyrifos, as EPA Stalls

(Beyond Pesticides, February 29, 2024)  In the face of federal inaction, an Oregon regulation banning the agricultural uses of the highly toxic chlorpyrifos took effect on January 1, 2024. Chlorpyrifos was voluntarily withdrawn from the market in 2000 for most residential uses by its manufacturer, Dow Chemical, and has been the subject of extensive litigation. At that time, the U.S. Environmental Protection Agency (EPA) allowed most agricultural uses to continue. Oregon joins four other states that have acted to ban chlorpyrifos, including Hawai’i, New York, California, and Maryland.  

Central to state action are nervous system and brain effects in children, especially farmworker children. Chlorpyrifos is banned in 39 countries, including the European Union (see here for more Beyond Pesticides coverage). State action has become important since the November 2023 decision by the U.S. Court of Appeals for the 8th Circuit, which overturned the EPA rule revoking all food tolerances for chlorpyrifos, an effective ban on chlorpyrifos use. The final EPA rule, issued in August 2021, came in response to a 9th Circuit Court of Appeals ruling that found the agency’s inaction on chlorpyrifos unlawful. The case was filed by Earthjustice, on behalf of public health, labor, and disability organizations. 

The Oregon Department of Agriculture began phasing out chlorpyrifos use three years ago. As of January 1, the state rule bans all uses of chlorpyrifos, except when used for commercial pre-plant seed treatments, applied to Christmas tree crops between April 1 and June 15 in granular form annually to control soil-borne pests, and in cattle ear tags.  

EPA’s inaction on chlorpyrifos spans decades. Following a petition filed in 2007 by Natural Resources Defense Council (NRDC) and Pesticide Action Network North America (PAN), the issue of chlorpyrifos’ safety moved through the courts—with the 9th Circuit Court of Appeals compelling EPA to reevaluate chlorpyrifos in compliance with the review process in 2021, finding that the agency’s action has been arbitrary and capricious. Prior to this decision, EPA missed numerous deadlines in response to the original 2007 petition. In 2015, the EPA administrator in the Trump administration, Scott Pruitt, rejected the conclusions of EPA scientists and independent scientific literature by reversing a tentative decision to revoke food residue tolerances of chlorpyrifos due to the chemical’s neurotoxic impacts. This would have effectively banned chlorpyrifos from agriculture.  

Poster child for pesticide regulatory failure 

As Jay Feldman, executive director of Beyond Pesticides observed, this disturbing pattern of regulatory failure by the EPA is not isolated. “EPA’s decision making, delay tactics, and contradictory policies are not confined to chlorpyrifos. Chlorpyrifos, glyphosate, 2,4-D, atrazine, and many others are poster children for a failed regulatory system that props up chemical-intensive agriculture despite the availability of alternative organic practices not reliant on these toxic chemicals,†Mr. Feldman said. “We have to end use of petrochemical pesticides and fertilizers and not just chase individual pesticides in an unending battle that allows the pesticide treadmill to continue destroying agriculture and harming farmworkers, farmers, and people generally.â€Â 

As the New York Times noted after the August 2021 9th Circuit ruling, “In an unusual move, the new chlorpyrifos policy will not be put in place via the standard regulatory process, under which the EPA first publishes a draft rule, then takes public comment before publishing a final rule. Rather, in compliance with the court order, which noted that the science linking chlorpyrifos to brain damage is over a decade old, the rule will be published in final form, without a draft or public comment period.” “It is very unusual,†Michal Freedhoff, EPA assistant administrator for chemical safety and pollution prevention, said of the court’s directive. “It speaks to the impatience and the frustration that the courts and environmental groups and farmworkers have with the agency.”  

“The court basically said, ‘Enough is enough,'” Ms. Freedhoff said. “Either tell us that it’s safe, and show your work, and if you can’t, then revoke all tolerances.†In a withering attack on EPA, Judge Jed S. Rakoff of the Ninth Circuit wrote on behalf of the court that, rather than ban the pesticide or impose restrictions, the agency “sought to evade, through one delaying tactic after another, its plain statutory duties.â€

Dow Chemical’s decision in 2000 to stop residential uses of chlorpyrifos, taken after extensive research highlighted the adverse impact on children, left its agricultural use unfettered for over 20 years due to EPA’s sustained inaction in the face of strong science. As Beyond Pesticides has warned before, EPA sits in the background and watches the marketplace, then codifies voluntary decisions by manufacturers after years, even generations, of poisoning and contamination. As a result, the voluntary actions by the companies are highly compromised and do not include agency determinations or findings—allowing false claims of safety, offering a shield from liability, and permitting unencumbered international marketing. 

Fast forward to 2024 and the reversal of years of science and court findings calling for an end to chlorpyrifos use. What could be characterized as “going back to square one,†the most recent Appeals Court finding in 2023 allows the agricultural uses to return to the market, except in the case of state action, like Oregon, Hawai’i, New York, Maryland, and California. Advocates continue to call for stronger mandates and a national goal to eliminate petrochemical pesticides, given the availability of productive and profitable organic practices. Federal Insecticide, Fungicide and Rodenticide Act and the Federal Food, Drug and Cosmetic Act (including the Food Quality Protection Act), continuously fail to adequately regulate chlorpyrifos, glyphosate, atrazine, 2,4-D, aldicarb, dicamba, neonicotinoids, synthetic pyrethroid, antimicrobials, and numerous others, including 1,200 active and hundreds of toxic “inert†(non-disclosed) ingredients in over 16,800 pesticide products.

A note about environmental justice 

Disproportionate impacts on low-income African American and Latino families, including farmworker families, continue with exposure documented, especially for farmworkers and their families. The threats from chlorpyrifos exposure are dire. Farmworker families tend to live in communities adjacent to treated fields and within the buffer zones of agricultural fields. Farmworker studies routinely show high exposure injury and disease from pesticide drift in these communities and other forms of contamination. As Beyond Pesticides reported in 2021, “Chlorpyrifos exposure lingers in the agricultural communities where farmworkers and their families reside. “We have found it in the houses, we have found it in carpet, in upholstered furniture, we found it in a teddy bear, and we found it on the walls and surfaces,†said Stuart Calwell, lead attorney for the plaintiffs in a 2021 lawsuit on behalf of some Californian farmworker families. “Then a little child picks up a teddy bear and holds on to it.†Ultimately, according to the attorneys, 100,000 people in California’s farming regions may need to remove items in their homes that were contaminated by chlorpyrifos. 

Each of the four plaintiff families has children with developmental disabilities that they indicate were caused by chlorpyrifos exposure. This real-world occurrence is supported by scientific literature. Studies find that children exposed to high levels of chlorpyrifos experience mental development delays, attention problems, attention-deficit/hyperactivity disorder problems, and pervasive developmental disorders at three years of age. Concentrations of chlorpyrifos in umbilical cord blood were also found to correspond to a decrease in psychomotor development and a decrease in mental development in 3-year-olds.  Additional research reinforces these findings, with evidence that children with high exposure levels of chlorpyrifos have changes to the brain, including enlargement of the superior temporal, posterior middle temporal, and inferior postcentral gyri bilaterally, and enlarged superior frontal gyrus, gyrus rectus, cuneus, and precuneus along the mesial wall of the right hemisphere. 

This toxic treadmill is not the sustainable way forward. The progress on one chemical like chlorpyrifos at the federal level, now reversed, required nonprofits, public health advocates, scientists, and people of good conscience to devote extraordinary resources in time and money at a period when a systemic overhaul is needed to meet the existential health, biodiversity, and climate crises to which petrochemical pesticides and fertilizers contribute significantly. The good news is that the solutions are within reach to move us forward with organic practices that sustain, nurture, and regenerate life.

Attack on Vulnerable Species Pilot Project: Opportunities to Engage with EPA on Endangered Species

(Beyond Pesticides, February 28, 2024) The U.S. Environmental Protection Agency (EPA) is putting on hold its Vulnerable Species Project (VSP) after vociferous comments from the petrochemical pesticide industry to instead, “create a narrow, tailored policy rather than a sweeping, burdensome one,†according to a recent op-ed in the Wall Street Journal. Upon heavy pushback from the petrochemical pesticide industry and agribusiness, EPA is hosting a variety of workshops and openings for the public to provide feedback not just on VSP, but the Endangered Species Act (ESA) Workplan the Biden Administration originally introduced in 2021 in its entirety. Advocates are calling for the strengthening of pesticide regulation given the impending decisions that may shape the fate of ESA-FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act) compliance for years to come.

As EPA continues through its pesticide registration program to advance continued dependency on pesticides through its interpretation of FIFRA, despite the availability of nontoxic alternatives, endangered species extinction and biodiversity collapse has never been a high priority. While EPA has initiated efforts to address a significant backlog of pesticide evaluations, Civil Eats has reported that the agency faces a task so extensive that it may require several additional decades to fully catch up. EPA officials stated, “Even if EPA completed this work for all of the pesticides that are currently subject to court decisions and/or ongoing litigation, that work would take until the 2040s, and even then, would represent only 5 percent of EPA’s ESA obligations.â€Â Â 

In this context, the VSP’s primary goal, according to the EPA website, “will [be to] identify certain vulnerable listed species, identify mitigations to protect them from pesticide exposure, and then implement these mitigations across different types of pesticides (e.g., herbicides, insecticides).†In response to widespread scrutiny from industry actors over the breadth of the pilot project, EPA issued a press release on February 7, “EPA Outlines Implementation Approach for Endangered Species Act Pesticide Policies.†There are three key components to this press release: “Improved†Species Map, Credit for using Voluntary USDA Conservation Practices, and Offsets for Endangered Species Protections.

The “Species Map,†according to the ESA Work Plan guide, “ are a group of StoryMaps to raise public awareness about protecting endangered species from pesticides. These StoryMaps use an interactive format to describe the 27 pilot endangered and threatened (listed) species, their habitats, and why they are vulnerable from pesticide exposure.â€Â The press release says, “In April, EPA plans to hold a workshop to facilitate and prioritize the development of [endangered species] maps, and EPA will also develop guidelines that the public can use to develop and submit refined maps for hundreds of other endangered species.†According to the Wall Street Journal opinion editorial, pesticide trade groups project that the pilot project would encompass 107 million acres across the United States, while EPA did not set a specific acreage. In November 2023, after receiving over 10,000 comments – many of which were from pesticide industry-aligned groups –EPA decided, among other changes, to “narrow the areas within the endangered species range map [for the Vulnerable Species Project] to only include locations that are important to conserving a species.†Beyond Pesticides will share more information regarding this workshop in the coming months.

The “Credit for using Voluntary USDA Conservation Practices†and “Offsets for Endangered Species Protections†sections, meanwhile, intend to substitute certain pollinator-friendly practices on the books for the introduction of new programs. Regarding USDA conservation practices, the press release says, “[On February 6], EPA signed an MOU (memorandum of understanding) with USDA describing how EPA can include NRCS (Natural Resource Conservation Service) conservation practices on pesticide labels as one way growers who voluntarily perform those practices can use them to help fulfill pesticide label requirements. EPA and USDA are planning meetings and workshops in the coming months to further discuss the MOU and gain input from producers about mitigation options that may count toward fulfilling pesticide label requirements.†EPA’s insistence on focusing on labeling rather than more stringent regulation has led to adverse health impacts and the proliferation of environmental contaminants into not only the food supply chain but also endangered and non-endangered species. Regarding the Offsets for Endangered Species Protections, “EPA, other federal agencies, and stakeholders are participating in a workshop…this month to discuss how to bring offsets into EPA’s ESA-FIFRA work. This initiative should give pesticide registrants and users more flexibility to meet label requirements to protect endangered species, while directly contributing to recovering those species.†Beyond Pesticides points out that the practical effect of the offset approach may allow continued toxic pesticide use in those very agricultural areas that are habitats to the most vulnerable species and the workplace of farmworkers and people of color communities. To the extent that chemical-intensive farming practices are curtailed to protect endangered species, straightforward enforcement of the law, as intended, may also protect those who suffer disproportionately from adverse health effects associated with pesticide exposure, including heightened risk to cancer for male farmworkers and anemia and blood disorders to female farmworkers and farmers.

Even before this pushback from industry, EPA’s ESA strategy has long missed the marked in terms of ensuring that pesticides do not move off the target site and threaten the health of wildlife, pollinators, and ecosystems. For example, EPA granted the use of nucleic acid, a form of genetically engineered pesticide, to eliminate the threat of Colorado Potato Beetles for potato farmers within the United States and abroad, without considering the inevitable drift from permitted aerial spraying on fields to unintendedly targeted wildlife. According to advocates, this move represents the legacy of agency indifference to pesticide resistance originating in 1952 with the discovery of Colorado Potato Beetle resistance to DDT. For advocates, this is seen as a lack of leadership by the EPA Office of Pesticide Regulations (OPR) over the past half-century that manifests in the continuous decline of biodiversity through adverse impacts to bird, insect (e.g. butterfly), marine, and aquatic life from pesticides such as paraquat and neonicotinoids, for example.

On the 50th anniversary of the passage of the Endangered Species Act, Beyond Pesticides, in partnership with multiple environmental organizations, highlights the historical successes of the ESA as well as areas of growth to further protect endangered species against the compounding tolls of the climate crisis on ecosystem balance, habitat fragmentation, and pollution resulting from petrochemical pesticides and fertilizers. The article points out, “The ESA is celebrated as one of the most effective conservation laws globally, credited with preventing the extinction of 99 percent of listed species. Over the past five decades, ESA has played a pivotal role in preventing these extinctions by safeguarding the most critically endangered species within biological communities.†However, OPR has not always kept biodiversity in mind regarding its rulemaking pursuant to ESA on “develop[ing] strategies to reduce harm from various pesticides, including herbicides and insecticides, while focusing on protecting the most vulnerable species.â€

These are critical times. The UN Development Programme in announcing its COP15: The Biodiversity Conference in 2022 provided context: “Despite ongoing efforts, biodiversity is deteriorating worldwide, and this decline is projected to worsen with business-as-usual. The loss of biodiversity comes at a great cost for human well-being and the global economy.†Advocates have told EPA that meeting ESA mandates will require a major shift away from pesticides, not mitigation that allows continued use despite the availability of certified organic practices.

There are numerous ways to take action to strengthen protections for endangered species against pesticides, including past Actions of the Week. See “Group Says Broader Biological Evaluation of Rodenticides Needed to Protect Endangered Species“ to learn more about biodiversity loss and the role that the Endangered Species Act is designed to play in protecting endangered species from rodenticides. See “Take Action Today: Tell EPA To End Pesticide Dependency, Endangered Species Plan Is Inadequate†to learn about the Draft Herbicide Strategy Framework and our position in advocating for the elimination of petro-chemical pesticide use by 2032. Beyond Pesticides will track the developments and upcoming public comment periods in relation to the recent press release in order to inform advocates on potential actions to call for further strengthening of the ESA Workplan.

Two ways that you can combat the negative impacts of pesticides on wildlife are to (1) implement organic practices for your own lawn and garden, and (2) support organic agriculture, rather than conventional agriculture, which relies on pesticide use. Beyond Pesticides supports organic agriculture as effecting good land stewardship and reducing wildlife’s hazardous chemical exposures. The pesticide reform movement, citing pesticide problems associated with chemical agriculture — from groundwater contamination and runoff to drift — views organic as the solution to these serious environmental threats. You can transition your communities’ public spaces to organic land management by becoming a parks advocate. Sign up today to learn how to protect children, pets, and pollinators in your local parks, playing fields, and other public spaces.
