(Beyond Pesticides, January, 23, 2019) Individuals that have been acutely poisoned by pesticides at some time in their life may be more likely to lose their sense of smell, according to a recent study published in Environmental Health Perspectives.  Researchers focused on the effect of high pesticide exposure events (HPEE), such as a pesticide spill or other incident, on a farmers’ ability to smell later in life. This is the first study to indicate pesticide exposure may result in olfactory impairment. Farmers from Iowa and North Carolina enrolled in an ongoing U.S. Agricultural Health Study have been asked about their pesticide use roughly every 5 to 6 years since 1993. In the most recent survey, taken from 2013-2015, farmers were asked additional questions about HPEE in their lifetime and whether they had a significantly decreased or impaired sense of smell. “Studying farmers gives us more reliable data on pesticide exposures than if we had studied the general population,” says Honglei Chen, MD, PhD, lead author and professor of epidemiology at Michigan State University in a press release. “Because they use pesticides more and it’s part of their job, they’re more likely to remember what pesticides they used and in cases […]

(Beyond Pesticides, January 22, 2019) Earlier this month, U.S. Representative Nydia Velásquez (D-NY) introduced The Ban Toxic Pesticides Act, H.R.230 which bans the insecticide chlorpyrifos from commerce. Chlorpyrifos is a toxic chemical that has been linked to damaging and often irreversible health outcomes in workers, pregnant women, and children. As a result of a revised human health risk assessment, the Environmental Protection Agency (EPA) developed a regulation to ban chlorpyrifos in 2016. Under the Trump Administration, the EPA has taken steps to reverse the regulation. “It’s unconscionable for EPA to turn a blind eye as children and workers are exposed to this poison,” Velázquez said.  “If the EPA won’t do its job when it comes to chlorpyrifos, then Congress needs to act – and do so quickly.” Ask your U.S. Representative to Co-Sponsor H.R. 230 to Stop the Use of the Toxic Insecticide Chlorpyrifos, which Is Damaging Children’s Brains.  Chlorypyrifos is a widely used pesticide. Agriculture companies annually spray 6 million pounds of the substance on crops like citrus, apples, and cherries.  In the same family as Sarin gas, the substance was initially developed prior to World War II as a chemical weapon. It can overstimulate the nervous system to cause […]

(Beyond Pesticides, January 14, 2019) Tell Congress to stop the Trump administration from opening the floodgates to permit widespread use of antibiotics in citrus production (grapefruits, oranges and tangerines). Despite the building national and international crisis of deadly bacterial resistance to antibiotics, this new allowance would expand on an emergency use decision the Environmental Protection Agency made in 2017. It permits up to 480,000 acres of citrus trees in Florida to be treated with more than 650,000 pounds of streptomycin per year; 23,000 citrus acres in California will likely be treated annually. The World Health Organization has called bacterial resistance “one of the biggest threats to global health, food security, and development today.” Tell your U.S. Senators and Representative to urge EPA to reject the use of antibiotics in food production, including citrus production. The two approved antibacterial chemicals to be used as pesticides in citrus production are streptomycin and oxytetracycline. Their use was permitted by the U.S. Environmental Protection Agency (EPA) under an emergency exemption in May, 2017 for a citrus greening disease caused by the bacterium Candidatus Liberibacter asiaticus (CLas) in Florida citrus crops through December of 2019. The Environmental Protection Agency announced March 15, “EPA is issuing these tolerances without notice and opportunity […]

(Beyond Pesticides, January 11, 2019) Plans to weaken farmworker protections from toxic pesticides were dropped by Acting U.S. Environmental Protection Agency (EPA) Administrator Andrew Wheeler, according to an undated letter sent to Senator Tom Carper (D-DE) late last year. Reports indicate the action was part of a deal cut by both parties that permitted confirmation of Alexandra Dunn to the EPA Office of Chemical Safety and Pollution Prevention in exchange for EPA concessions that would improve pesticide and chemical safety measures. While advocates are generally pleased with the outcome of the apparent deal, the irony that deals needed to be made for an agency with protection in its name to do its job is not lost. Under former EPA Administrator Scott Pruitt, the agency backtracked on provisions put in place during the Obama administration that would update farmworker protections following decades of inaction. Pruitt determined to revisit rules put in place that would require farmworkers be 18 to spray highly toxic pesticides, implement 25 to 100 ft application exclusion zones (AEZ) after pesticide applications, and permit farmworkers to have a designated representative obtain health and safety information on their behalf. These simple, commonsense protections were strongly opposed by the agrichemical […]

(Beyond Pesticides, January 7, 2019) As the dust settles on the final Farm Bill, which passed the U.S. Senate and House of Representatives last month, it is clear that neither the substance nor the process on a range of issues meet the urgent need to address key sustainability issues that put the future in peril. We must not allow this Farm Bill to be the final word on a number of critical environmental issues facing the nation and world. That is why it is absolutely critical that we get to work immediately, with the new Congress, to set a new course that transforms the institutions of government that are holding back the urgently needed transition to a green economy. Tell your Senators and Representative to support a Green New Deal that restructures food and agriculture programs. On the Farm Bill, our victories were mostly measured in terms of what we were able to remove from the Farm Bill—not the standard of achievement that we need to face critical environmental threats.  The good. Our major victory in the Farm Bill does not move us forward, but simply protects the status quo of our democracy—protecting the power of states and local government to […]

(Beyond Pesticides, December 19, 2018) As the dust still settles on the final Farm Bill, which passed the U.S. Senate and House of Representatives last week, it is clear that neither the substance nor the process on a range of issues meet the urgent need to address key sustainability issues that put the future in peril. We must not allow this Farm Bill to be the final word on a number of critical environmental and public health issues facing the nation and world. That is why it is absolutely critical that we get to work immediately, with the new Congress, to set a new course that transforms the institutions of government that are holding back the urgently needed transition to a green economy. On the Farm Bill, our victories were mostly measured in terms of what we were able to remove from the legislation—not the standard of achievement that we need to face critical environmental threats. The good. Our major victory in the Farm Bill does not move us forward, but simply protects the status quo of our democracy—protecting the power of states and local government to adopt pesticide restrictions that are more stringent than the federal government. With your help […]

(Beyond Pesticides, December 18, 2018) The ingredients not listed on a pesticide product are not fully reviewed for their adverse effects may be the most toxic chemicals in the formulation. Recent research, Toxicity of formulants and heavy metals in glyphosate-based herbicides and other pesticides (Toxicology Reports 5, 2018), by Defarge, de Vendômois, and Séralini demonstrates the need to disclose and test all ingredients in pesticide products, as well as the full formulation that includes “inert” or nondisclosed ingredients. While glyphosate/Roundup is obviously not allowed to be used in organic production, this research reaffirms the need to evaluate full formulations of substances allowed for use in organic. The research on glyphosate tested the toxicity of the herbicide glyphosate, “inerts” in glyphosate-based herbicides (GBH), and the pesticide formulations–looking at toxicity to target organisms, toxicity to human cells, and endocrine-disrupting activity. In addition to the GBH products, the researchers studied a number of other pesticides. Tell NOP and USDA that “inerts” used in organic production must receive full review by the NOSB. “Inert” ingredients are allowed in pesticides used in organic production as well as those used in chemical-intensive production. The National Organic Program (NOP) allows “inerts,” permitted in conventional production and formerly listed […]

(Beyond Pesticides, December 12, 2018)  Costa Rica is currently experiencing exponential growth in its banana and pineapple farming industries and with it an increase in intensive pesticide applications. Recent studies in Costa Rica identified evidence of increasing fur discoloration in black mantled howler monkeys ((Alouatta palliata) as a result of their exposure to sulfur-based pesticides. Coloration in Howler monkeys are limited to black, gray, and dark brown, but researchers found several monkeys with yellow patches on their tails and legs. The change in pigmentation is directly correlated to the consumption of plants inadvertently exposed to sulfur-based pesticides sprayed at (and drifting from) nearby farms. The use of pesticides is not only hazardous to nearby wildlife, but communities as well. It is an issue that seems to play out repeatedly both in Costa Rica and in the U.S. The use of pesticides, and more importantly pesticide drift, continues to be a pervasive issue with severe human and environmental health consequences. Pesticide drift occurs in the form of mist, particles, or vapor (gas) and are usually carried by air (and oftentimes water) currents. Typically, fumigants (gaseous pesticides) are most likely to drift.  When used, pesticides regularly spread further than the established application […]

(Beyond Pesticides, December 10, 2018) The Senate Agriculture Committee has cleared the way for the whole U.S. Senate to vote on the confirmation of Scott Hutchins, PhD, recently retired from research and management at what is now the agricultural division of DowDuPont, as chief scientist at the U.S. Department of Agriculture (USDA). If confirmed, he will become the third member of Dow’s pesticide and seed division to hold a high-level position in the Trump administration’s USDA.  Tell your U.S. Senators to Reject Dow’s Hutchins as USDA Chief Scientist. Dr. Hutchins has a history of defending toxic pesticides like Dow’s chlorpyrifos, which makes him unsuitable for leading USDA’s research on the future of the U.S. food system. The chief scientist at USDA can determine the direction of USDA research–which should be shaped by an organic, rather than a chemical-intensive, vision. USDA needs a chief scientist who will help farmers get off the pesticide treadmill and adopt organic practices that address critical issues of protecting farmer and farmworker health, water resources, biodiversity, and soil health, while reducing the escalating crisis in global climate change. USDA’s research mission must be focused on sustainability and protect farmers, families, and the environment. Since 1987, Dr. Hutchins […]

(Beyond Pesticides, December 6, 2018) A recent analysis of annual drinking water quality reports has revealed that many community drinking water systems in the Midwest have seasonal exceedances of the allowable limit for the herbicide atrazine. Atrazine, linked to endocrine disruption, neuropathy, and cancer, is the second most widely used pesticide in corn growing areas, with over 73 million pounds applied to agricultural fields each year.  A 2009 study by Paul Winchester, MD, professor of clinical pediatrics at Indiana University School of Medicine and a neonatologist at St. Francis Hospital in Indianapolis, linked birth defects to time of conception, with the greatest impact on children conceived when concentrations of atrazine and other pesticides are highest in the local drinking water. (See Reproductive Effects Peak with Pesticide Exposure.) During peak use, atrazine levels in drinking water have been recorded at three to seven times above the legal limit. In addition to the well documented impact on the environment, recent  studies have linked prolonged pesticide exposure to not only shortened gestation and preterm birth for women, but also neurodevelopment delays in children. Ultimately, these unreported seasonal peaks may result in persistent adverse health impacts in impacted communities. The Safe Drinking Water Act (SDWA), enacted in 1974, […]

(Beyond Pesticides, December 4, 2018) In mid-November, the state whose agricultural operations used more than 900,000 pounds of chlorpyrifos in 2016 (down from two million pounds in 2005) moved to establish some temporary restrictions on its use. Regulators at the California Department of Pesticide Regulation (CDPR) issued interim restrictions on the compound while the agency works on a formal regulatory process to list chlorpyrifos as a “toxic air contaminant” and develop permanent restrictions on its use. A neurological toxicant, chlorpyrifos damages the brains of young children: impacts of exposure, even at very low levels, include decreased cognitive function, lowered IQ, attention deficit disorder, and developmental and learning delays. It was slated to be banned for food uses by the U.S. Environmental Protection Agency (EPA) last year, but the decision was reversed by the Trump administration. The interim measures in California include: banning aerial application of chlorpyrifos; ending its use on many crops — except for those determined to be “critical” by virtue of there being few, if any, alternatives (as determined by the University of California Cooperative Extension and listed on DPR’s website); establishing a quarter-mile buffer zone for 24 hours after any application of the pesticide; and requiring a 24/7/365, 150-foot […]

(Beyond Pesticides, November 28, 2018) Recent research out of Harvard University and published in the journal Science has demonstrated some of the mechanisms through which exposures to neonicotinoid pesticides harm bumblebee populations. The study found that exposure to imidacloprid, a neonicotinoid — the most widely used category of pesticides worldwide — directly impacts social behaviors in bumblebees. These behaviors have serious effects on the functioning and viability of bee colonies. In the research experiment, worker bees exposed to imidacloprid exhibited reduced general and nurturant activity, and a tendency to locate themselves at the periphery of the nest. The study noted decreased caretaking and nursing behaviors, which in turn harms productivity and thermal regulation in the colony. These tasks are important to colony development; impaired thermoregulation negatively affected the bees’ typical construction of an insulating wax canopy for the nest, and poor caretaking can affect brood growth. Investigators noted that, “Neonicotinoids induce widespread disruption of within-nest worker behavior that may conribute to impaired growth. . . . These changes in behavior acted together to decrease colony viability, even when exposure was nonlethal.” The authors also observed that many of these dysregulated behaviors were more pronounced at night than during sunlight hours, and […]

(Beyond Pesticides, November 27, 2018) The U.S. Environmental Protection Agency (EPA) ignored the input of an expert weed scientist on the controversial herbicide dicamba, bending to Bayer’s Monsanto and the pesticide industry, according to emails obtained by the Arkansas Democrat and Chronicle (ADC) through a Freedom of Information Act request. The scandal centers on the recent re-approval of the pesticide, a highly volatile and drift-prone herbicide that has become a serious problem for many farmers and state regulators. As top-level EPA officials continue to work with industry to subvert their own agency’s scientific findings, more and more consumers are moving to organic products in order avoid the pesticide risks government regulators ask consumers to accept. Emails ADC received indicate that Jason Norsworthy, PhD, a weed scientist with the University of Arkansas, worked closely with Bayer’s Monsanto in conducting field trials this past summer, but found high volatility and drift of the company’s new dicamba-based herbicide XtendiMax. The product was developed in the face of widespread resistance to glyphosate-based herbicides in genetically engineered (GE) farm fields. However, recent accounts from farmers in the south and midwest indicate that, not only is the switch to dicamba unhelpful  in eliminating drift and reversing escalating weed resistance, its […]

(Beyond Pesticides, November 26, 2018) Organic consumers expect that the organic products they buy are grown without toxic chemical inputs. However, oil and gas wastewater (including fracking wastewater) is currently used to irrigate crops. Among the chemicals known to be present in oil and gas wastewater are heavy metals and other chemicals with carcinogenic, reproductive, developmental, endocrine-disrupting, and other toxic effects. When the Organic Foods Production Act (OFPA) was passed, and regulations adopted, there was no agricultural use of oil and gas wastewater, so the regulations did not address these hazards.  Tell USDA to Outlaw Fracking Wastewater in Organic Production!  The Cornucopia Institute has filed a petition for rulemaking, asking that oil and gas wastewater be ruled a prohibited substance in organic production. This issue should be put on the work agenda of the National Organic Standards Board (NOSB), which advises the Secretary about issues concerning NOP. The petition from the Cornucopia Institute contains information that will serve as support for the work agenda item. Over the past several years, the NOSB has received many comments requesting them to address this issue Among the comments have been suggestions for guidance to farmers faced with contamination from oil and gas activities. The […]

(Beyond Pesticides, November 19, 2018) The Organic Foods Production Act (OFPA) requires organic milk and dairy products labeled as organic to come from dairy cows continuously managed as organic from the last third of gestation. Because of the short supply of organic dairy breeder stock when the law was passed in 1990, a one-time conversion of conventional dairy cows to organic was allowed, as long as they are managed organically. Please urge the Secretary of Agriculture to issue a final rule for Origin of Organic Livestock, as urged by the NOSB. Unfortunately, the National Organic Program (NOP) allowed two interpretations of this provision, turning the provision into a loophole that has allowed some large dairy operations to circumvent the last third of gestation requirement altogether, and bringing conventionally managed animals into their operations on a continuous basis. In 2015, USDA proposed an Origin of Livestock rule to clarify that section of the law and ensure consistent enforcement of the standards, but appears to have no plans to finalize the rule. In its October 2018 meeting, the National Organic Standards Board (NOSB) recognized the unfairness that allows large organic dairies to profit at the expense of smaller dairies who follow the spirit […]

(Beyond Pesticides, November 7, 2018) Brazil’s rapid industrialization of its agricultural sector may be coming at the cost of resident health, according to a new study published in Chemosphere by an international team of scientists. The researchers link the rise in the country’s pesticide use since the turn of the century to significant increases in colon cancer, particularly in the country’s most intensive agricultural southern regions. With the recent election of far right president Jair Bolsonaro, who has supported policies that would loosen Brazil’s pesticide regulations, advocates are concerned the county’s farming industry is moving in an unsustainable direction. Researchers note that as Brazil’s agriculture industry has grown over the last two decades, it has become the world’s leading consumer of pesticides. In the year 2000, roughly 160 million tons of pesticides were used in the country. By 2012, that number reached nearly 500 million tons. Scientists compared pesticides sold to standard mortality rates (SMR) in each Brazilian state. SMR measures mortality by comparing observed mortality to expected mortality when adjusting for age and gender. A rate above one indicates that there is excessive mortality. Despite improvements in detection and treatment, colon cancer deaths recorded in the country increased from […]

(Beyond Pesticides, November 2, 2018) A group of leading toxics experts, who published a paper in the journal PLOS Medicine on their research on organophosphate exposure during pregnancy and impacts on child development, are calling for a ban on organophosphate pesticides. The study evaluates current science on the risks of this class of compounds, produced by Corteva Agriscience (formerly Dow AgroSciences); its conclusions warn of the multitude of dangers of organophosphates for children, and makes recommendations for addressing these risks. The experts conclude that: (1) widespread use of organophosphate (OP) pesticides to control insects has resulted in ubiquitous human exposures; (2) acute exposures to OPs is responsible for poisonings and deaths, particularly in developing countries; and (3) evidence demonstrates that prenatal exposures, even at low levels, put children at risk for cognitive and behavioral deficits, and for neurodevelopmental disorders. Among the authors’ recommendations are these: Governments and subsidiary agencies, including the Environmental Protection Agency (EPA), should phase out chlorpyrifos and other organophosphate pesticides; ban non-agricultural uses of OP pesticides (including in household products); monitor watersheds and drinking water sources of human exposure; promote the use of integrated pest management (IPM) through incentives and training; and establish pesticide use and illness reporting […]

(Beyond Pesticides, November 1, 2018) A new study offers fresh evidence that wild bumblebee pollinators are particularly vulnerable to the impacts of neonicotinoid (neonic) insecticides, finding that exposure to these compounds interferes with mating success and population stability. Researchers from Worcester Polytechnic Institute in Massachusetts, measuring real-world harms of neonicotinoids, indicate that the impacts they found to bumblebee “reproducers,” namely queen and drone (male) bees, does not bode well for the array of plant species that relies on them. Though advocates warn that destabilizing managed pollinators could threaten U.S. food production and exports, with food prices increasing as cost of bringing pollinators to farms increases, the study’s authors and advocates insist that the impacts of such widespread poisoning of wild bees could be felt well beyond agriculture. Researchers in the lab compare behavioral and psychological responses of virgin queens, workers, and male Bombus impatiens from multiple colonies to field-realistic doses of the neonicotinoid clothianidin. While every bee was given a replenishing supply of pollen based on body weight and energy demands, four distinct concentrations of diluted analytical-grade (pure) clothianidin (including a control with no pesticide added) were mixed into a nectar-like solution and fed to the bumblebees orally for 5 […]

(Beyond Pesticides, October 24, 2018) Bottlenose dolphins found along Florida’s west coast contain detectable levels of phthalates, chemicals used in plastics, cosmetics and as inert ingredients in pesticide products, research published in the journal GeoHealth last month indicates. The study, published by scientists from the College of Charleston, South Carolina, is the first to find detectable levels of these toxic industrial byproducts in dolphins. Given the transient nature of urinary detection, the findings indicate that dolphins and other marine mammals are at increased risk of health effects related to phthalate exposure. Scientists sampled a total of 17 dolphins found in Sarasota Bay, FL over the course of two years. Of the 17, phthalates were detected in 12 individuals, or 71% of dolphins. The type of phthalates discovered was indicative of the source of the contaminant. With researchers detecting mono‐(2‐ethylhexyl) phthalate (MEHP) and monoethyl phthalate (MEP) most frequently. While MEHP is associated with plastic pollution, MEP is a breakdown product of diethyl phthalate (DEP), a compound that has been used in pesticide products as an inert ingredient. “These chemicals can enter marine waters from urban runoff and agriculture or industrial emissions, but we also know that there is a lot of […]

(Beyond Pesticides, October 23, 2018)  The Chief Minister of the Sikkim state in northeast India, Pawan Chamling, addressed a news conference in the Italian Parliament on October 15 to issue a call for a complete, global transition to organic agriculture by 2050. Citing the increasing dangers of climate disruption and its impacts, Mr. Chamling said that such conversion to pesticide- and petrochemical-free practices would reduce carbon emissions by 50%. The call for banning pesticides in communities and countries nationwide is gaining increasing traction, as the shift to organic land management is increasing exponentially. The town of Mals, Italy (93 square miles in area, encompassing ten villages and hamlets, as well as farmland, home to 5,092 people) passed a ban on a ballot initiative with 75% in favor and 69% of the electorate voting. In 2013, the country of Bhutan adopted completely organic practices  throughout its nation. Although not affecting agricultural pesticide use, towns across the U.S. are adopting measures that stop pesticide use community-wide. Ordinances in the cities of Ogunquit, South Portland, and Portland, Maine and the City of Takoma Park, Maryland are examples of city-wide pesticide bans. A petition in Switzerland calls for the banning of pesticides country-wide. States in northeast India — […]

(Beyond Pesticides, October 22, 2018) The California Department of Pesticide Regulation (DPR) is accepting comments on its proposal to classify chlorpyrifos as a toxic air pollutant. The classification would require DPR to develop control measures that adequately protect public health. What happens in California affects all of us because products of California agriculture are available all over the country –and the world. In addition, policies set by the state of California are often examples for other states and the federal government. Tell California Department of Pesticide Regulation to ban chlorpyrifos. California’s Office of Environmental Health Hazard Assessment (OEHHA) states: Under the Toxic Air Contaminant Identification and Control Act (AB 1807, Chapter 1047, Statutes of 1983) and its implementing regulations (Title 3, California Code of Regulations, Section 6864), one of the criteria for identifying a pesticide as a TAC is if its concentration in the air exceeds one-tenth of the level that has been determined to be adequately protective of human health. The draft TAC document shows that bystanders can be exposed to modeled air concentrations of chlorpyrifos that exceed one-tenth the protective level, and thus meet the criteria for TAC identification. OEHHA’s findings below serve to reinforce this overall conclusion, and […]

(Beyond Pesticides, October 19, 2018) Pollinator advocates and the Center for Biological Diversity (CBD) are imploring the U.S. Environmental Protection Agency (EPA) to deny Bayer CropScience’s application for use of “Sivanto,”a pesticide product with the active ingredient flupyradifurone, a chemical the company claims is safer for bees, but poses the same risks at the notorious bee-toxic neonicotinoid insecticides. If approved, Sivanto would be sprayed in tobacco-growing states along 300,000 acres in the southeast U.S., areas home to more than three dozen species protected under the Endangered Species Act (ESA). Bayer’s proposal for expanded uses comes after EPA’s own assessment indicated risks to endangered species, and despite the fact that the agency has not undergone an ESA mandated consultation with federal wildlife agencies. For the countless flying insects, birds, and bats already under significant threat from neonicotinoids, adding another systemic insecticide to the mix will only make the situation worse. Bayer AG is characterizing flupyradifurone as being harmless to honeybees. However, flupyradifurone, being a systemic pesticide, can negatively impact many non-target species.  In fact, flupyradifurone impacts honey bee brains in a similar way to neonicotinoids, as it impairs learning, memory and the honey bees’ affinity for nectar rewards. Advocates worry that growing […]

(Beyond Pesticides, October 16, 2018) Bacteria exposed to widely used herbicides like Roundup develop antibiotic resistance 100,000 times faster than average, according to new research published by New Zealand scientists in PeerJ. The results have ominous implications for the modern world’s ability to avert a post-antibiotic era. Even if new antibiotics are discovered, or existing compounds used more judiciously, scientists say that will not be enough to prevent the ongoing crisis – the world is also confronting bacterial exposure to herbicides and other non-antibiotic agents that have the ability to rapidly induce resistance. “Herbicides are among the most widely used and dispersed manufactured products on Earth. Some form of exposure for people, pets and livestock can be routinely expected,” study author Jack Heinemann, PhD, told Newsweek. “Meanwhile, antibiotics are used at high rates particularly on people, pets and livestock. Therefore, the combination of exposures for bacteria that live on us is all but guaranteed.” This current round of research by Dr. Heinemann and his team is the outgrowth of previous studies (1, 2) that established the ability of common herbicides to induce antibiotic resistance in strains of pathogenic bacteria Salmonella eterica and Escherichia coli. Now, the scientists are drilling into […]
