(Beyond Pesticides, May 8, 2019) The spread of antibiotic resistance is a health care crisis of major proportions and requires a moratorium on the use of antibiotics in agriculture. The Centers for Disease Control (CDC) call antibiotic resistance “one of the world’s most pressing public health problems.” Many bacterial infections are becoming resistant to the most commonly prescribed antibiotics, resulting in longer-lasting infections, higher medical expenses, and the need for more expensive or hazardous medications. The development and spread of antibiotic resistance is the inevitable effect of the use of antibiotics. Bacteria evolve quickly, and antibiotics provide strong selection pressure for those strains with genes for resistance.

Tell EPA and Congress to save antibiotics for important medical uses and eliminate use as pesticides.

In spite of the spread of antibiotic resistance, the antibiotics used in plant agriculture are both important for fighting human disease. Tetracycline is used for many common infections of the respiratory tract, sinuses, middle ear, and urinary tract, as well as for anthrax, plague, cholera, and Legionnaire’s disease, though it is used less frequently because of resistance. Streptomycin is used for tuberculosis, tularemia, plague, bacterial endocarditis, brucellosis, and other diseases, but its usefulness is limited by widespread resistance.

Use of antibiotics on fruit trees can contribute to resistance to the antibiotic in human pathogens. The human pathogenic organisms themselves do not need to be sprayed by the antibiotic because movement of genes in bacteria is not solely “vertical” –that is from parent to progeny– but can be “horizontal” –from one bacterial species to another. So, a pool of resistant soil bacteria or commensal gut bacteria can provide the genetic material for resistance in human pathogens.

When bacteria on the plants and in the soil are sprayed with an antibiotic, those with genes for resistance to the chemical increase compared to those susceptible to the antibiotic. Resistance genes exist for both streptomycin and tetracycline, and spraying with these chemicals increases the frequency of resistant genotypes by killing those susceptible to the antibiotic and leaving the others. Those genes may be taken up by other bacteria by a number of mechanisms, collectively known as “horizontal gene transfer.”

The guts of humans and other animals provide efficient incubators for antibiotic resistance. Antibiotic resistance increases first in commensal bacteria—the bacteria that naturally live within our bodies—and may then be transferred to pathogens. Thus, the argument that human pathogens are not present in orchards sprayed with antibiotics is irrelevant to the actual development and spread of bacteria resistant to antibiotics. The number of bacteria in the gut is large –often more than 10¹⁴ bacteria of several hundred species—with a large gene pool offering many mechanisms of resistance, and every exposure to antibiotics offers new opportunities for selection for resistance.

Antibiotics from use on animals and crops are washed into waterways, where they find another environment perfect for encouraging the growth of antibiotic-resistant bacteria. Aquatic environments are rich in bacteria, providing another place where pathogens can obtain genes for resistance.

It is important to eliminate uses of antibiotics in agriculture that can contribute to antibiotic resistance in human pathogens. Instead, EPA has been increasing those uses and fails to count antibiotic resistance as a health risk to humans.

Tell EPA to save antibiotics for important medical uses and eliminate use as pesticides.

Letter to EPA Administrator and Director of the Office of Pesticide Programs:

The spread of antibiotic resistance is a health care crisis of major proportions. The Centers for Disease Control (CDC) call it “one of the world’s most pressing public health problems.” Many bacterial infections are becoming resistant to the most commonly prescribed antibiotics, resulting in longer-lasting infections, higher medical expenses, and the need for more expensive or hazardous medications. The development and spread of antibiotic resistance is the inevitable effect of the use of antibiotics. Bacteria evolve quickly, and antibiotics provide strong selection pressure for those strains with genes for resistance.

It is important that EPA recognize the importance of antibiotic resistance as a human health threat. Antibiotics that are used to fight human disease should not be used as pesticides, where they can pose serious threats to human health. We implore EPA to fully consider the spread of antibiotic resistance through horizontal gene transfer, as resistant pathogenic bacteria spread throughout the environment.

Please eliminate pesticide products containing antibiotics used to fight human diseases.

Thank you.

(Beyond Pesticides, May, 7, 2019) Last week, the New York State legislature voted to phase out and eventually ban the use of the neurotoxic insecticide chlorpyrifos. The vote, 44-18 in the state Senate and 94-50 in the Assembly, is still awaiting the Governor’s signature, who is expected to sign the measure. As evidence of harm continues to accumulate, scientists have called for a ban, and a legal case works its way through the courts, pressure is mounting on the U.S. Environmental Protection Agency (EPA) to once and for all remove this harmful pesticide from use.

New York’s legislation sets implementation dates that leapfrog a similar law banning chlorpyrifos that passed in Hawai’i last year. Although Hawai’i’s law takes effect beginning in July of this year, the state may provide temporary use permits for the chemical until December 2022. New York also phases in restrictions, first prohibiting aerial applications beginning January 2020, then prohibiting all use except on apple trees starting January 2021. The chemical will be completely banned for use in New York in December 2021.

Chlorpyrifos is a highly toxic insecticide that has been linked to damaging and often irreversible health outcomes, particularly for pregnant mothers and their children, who are at risk of learning disabilities, including lowered IQ, developmental delay, and attention deficit/hyperactivity disorder (ADHD). Recent evidence shows that the original data used to register this chemical was fundamentally flawed in its assessment of health risks.

Other states are also considering their own chlorpyrifos bans. In Maryland, a chlorpyrifos bill that passed in the state House of Delegates was not taken up for a vote in the Senate. In California, a bill passed its first committee hearing in early April. Bills are also being considered in Oregon and Connecticut.

Overlaying this state level activity is legislation at the federal level. Senator Brian Schatz (D-HI) has introduced S 3764, The Prohibit Chlorpyrifos Poisoning Students Act, to ban chlorpyrifos and implement pesticide buffer zones around schools. Senator Tom Udall (D-NM) has, since 2017, introduced S921, the Protect Children, Farmers and Farmworkers from Nerve Agent Pesticides Act of 2019, to prohibit all uses of chlorpyrifos on food. And Senator Gillibrand (D-NY) has introduced the S1187, Safe School Meals for Kids Act, which would eliminate chlorpyrifos on food served in school cafeterias. In the U.S. House of Representatives, Congresswoman Nydia Velázquez (D-NY) introduced HR 230, the Ban Toxic Pesticides Act, which eliminates chlorpyrifos from commerce.

Although EPA recommended a ban on food uses of chlorpyrifos in 2016, under the Trump Administration, the agency has taken steps to reverse the decision. This long court battle appears to be at another inflection point, as the US 9^th Circuit Federal Court of Appeals on April 19, 2019 gave EPA 90 days to either justify use of the chemical or prohibit its use in agriculture.

While focus on chlorpyrifos is sorely needed, and will do much to eliminate hazards to pregnant mothers, children, and farmworkers, there is a need to ensure that the pesticide products that present similar risks are not used as replacements. A good start would be to follow the recommendation of renowned scientists and ban all organophosphate insecticides, which have a similar mode of action to chlorpyrifos. But even that step leaves on the market insecticides like synthetic pyrethroids, which are also hazardous to children, the bee-toxic neonicotinoids, frog killing fungicides, and carcinogenic herbicides like glyphosate and 2,4-D.

What is needed, in the long-term, is a wholesale transition of U.S. agriculture to organic practices. Many balk at the suggestion, but study after study has found this solution to be worth the investment – for local economies,  human health, in the battle against the climate crisis, and for a sustainable future.

The pesticide industry has convinced many that it would be impossible to “feed the world” with organic agriculture. However, as UN special rapporteur on the right to food, Hilal Elver, PhD, said in 2017, “It is a myth. Using more pesticides has nothing to do with getting rid of hunger. According to the UN Food and Agriculture Organization (FAO), we are able to feed 9 billion people today. Production is definitely increasing, but the problem is poverty, inequality and distribution.”

Since Rachel Carson stunned the world and ignited the modern environmental movement with Silent Spring, pesticide regulation has been stuck in a whack-a-mole approach that targets only the most publicly visible, toxic, and researched chemicals for restrictions. By transitioning to organic, not only in food production, but also in the management of pests in lawns and landscapes, and other pest control practices, we can eliminate the broad range of chemicals linked to diseases that are all too common in today’s world, and truly protect public health, wildlife, and the environment.

(Beyond Pesticides, May 6, 2019) Beleaguered pollinators deal with a multitude of human-engineered threats: habitat fragmentation and loss via development and agricultural intensification, ecosystems and food sources tainted with toxic synthetic pesticides, and shrinking food sources via habitat and biodiversity loss. Research out of the Imperial College of London shows that such challenges are exacerbated, for bumblebees, by another impact of pesticide exposure — impaired flight endurance and dynamics.

Published in the journal Ecology and Evolution in late April, ”Pesticide exposure affects flight dynamics and reduced flight endurance in bumblebees” examines how acute exposure to the neonicotinoid imidacloprid affects the nature of bumblebee foraging flight. The study’s researchers find that worker bumblebees so exposed exhibit significant diminishment of flight endurance — measured as both distance and duration — to approximately one-third of what control workers demonstrate. This new information, aggregated with the many other factors that threaten pollinators, points to the importance of ending the use of chemical controls, such as the neonicotinoid imidacloprid, and transitioning to organic systems of agricultural pest management that do not rely on toxic compounds that harm wildlife, ecosystems, water resources, and humans.

Previous research has shown numerous impacts of pesticide exposure on bumblebees, and of neonicotinoid exposure, in particular, including: reproductive failures, alteration of gene expression, harmful changes in attraction to food sources, reduced colony nurturance activity, and decreased foraging activity, as well as colony size. Although acute exposures to pesticide residues may not be lethal to bumblebees, these sublethal effects on them and their behaviors can cause very significant degradation in colony functioning and health.

Flight capacity is obviously critical to bumblebee health and survival, and to those of the colony. The subject paper adds, “While both control and pesticide‐exposed workers were equally motivated to fly initially, pesticide‐exposed workers had a higher probability of terminating flight before the end of the 60‐min[ute] flight test, which was even evident within the first 100 m[eters]. Intriguingly, pesticide workers exhibited a higher mean velocity compared with control workers, which was underpinned by faster flight speeds over the course of the first ¾ km, both during and after which we observed a considerable proportion of pesticide workers terminating their flight. Furthermore, our results suggest that pesticide exposure may negate the capability of larger workers to fly longer distances than their smaller sister workers. . . . Our flight tests suggest that imidacloprid‐exposed bumblebee workers experienced a rapid demotivation to fly as the test progressed and/or tired quickly leading to premature physical exhaustion.”

The study used a “controlled tethered flight mill,” equipment that allows the bees to fly in a laboratory, rather than in situ, but lets scientists measure numerous aspects of that flight, as well as pre- and post- status of the insect controls and those exposed to imidacloprid. The research shows that exposure to the neonicotinoid seems to impair not initial motivation to fly, but flight stamina. The compound has previously been implicated in degraded honeybee energy metabolism, and in reduced activity in the mitochondria (cellular energy centers) in bumblebees and honeybees, which could potentially cause rapid muscle fatigue and, thus, foreshortened flights. The faster flights may be explained by the increased neuronal activity shown to be a function of neonicotinoid exposure.

When bumblebees fly to forage for food, they need the stamina to get to the sources, and then return to the nest. Researchers proffer a necessary minimum, round-trip, flight distance range for them of .68–4.4 kilometers, but note that the pesticide‐exposed worker bumblebees flew shorter distances, on average, than the lower limit of this range. Exposure to imidacloprid appears to have reduced total flight distance by nearly 1.2 km, on average, which represents a 64% reduction compared to the average flight distance of the research controls. The dramatic net metric, however, lies in researchers’ conclusion that this difference would lead to an 87% decline in the total foraging area accessible to a colony — reducing the diversity, nutritional quality, and abundance of food available. Thus, exposures to neonicotinoid pesticides — which are very commonly used, particularly as plant seed coatings, despite questionable utility — have the potential to stress, significantly and cumulatively (with other stressors), the success of bumblebee colonies and their role as critical pollinators, never mind their survival.

Pests can be prevented and managed safely without the use of neonicotinoid or other pesticides. Pollinators can be protected through improved public policy and regulation, and smart choices by home and land owners. As Beyond Pesticides has written, “There is an alternative to the indiscriminate poisoning of pollinators and ecosystems. A solution exists that is effective, productive, economically viable, and sustainable and does not require yet another new toxic pesticide or genetically engineered crop: organic land management. By respecting the environment, the complexity and benefits of interconnected ecosystems, organic agriculture protects pollinators and enhances the benefits we derive from the natural environment.”

(Beyond Pesticides, May 3, 2019) A Maryland Court of Special Appeals yesterday ruled that Montgomery County, Maryland has the right to restrict pesticides, under a 2015 landmark law, on all lawns and landscaped property in its jurisdiction more stringently than the state. This decision reverses a lower Circuit Court decision and upholds local democratic decision making in the face of a challenge by the industry groups representing lawn care companies and chemical manufacturers. Nine organizations, including Beyond Pesticides, filed an Amicus brief in support of the county law.

The chemical industry has fought for nearly three decades to suppress the right of local governments in the U.S. to protect public health and safety with pesticide law, having successfully lobbied 43 states to preempt their local political subdivisions’ authority. Seven states uphold local authority, including the state of Maryland, which has affirmed in its legislature the rights of localities by rejecting preemption legislation on numerous occasions.

According to Jay Feldman, executive director of Beyond Pesticides, “This is an important win for the local organic land management movement sweeping the country, as local elected officials embrace practices that protect the health of people and the environment.” The attorneys for the county expect that industry groups will file a petition for a writ of certiorari (judicial review) and request a stay of enforcement with the Court of Appeals.

“This important state court decision affirms local democratic decision making to protect health and the environment, upholding the first U.S. county law  to ban toxic pesticides used on lawns on both private and public property,” said Mr. Feldman.

In the Court’s words:

From 1958-1962, Rachel Carson wrote Silent Spring from her home in Silver Spring. Carson’s examination of the health impacts of DDT and other pesticides galvanized the public, and the next decade saw Congress enact a broad range of statutes that are foundational to modern environmental law. Montgomery County claims, in essence, that it is following in these footsteps, but we must determine whether it has done so consistently with State law.

In 2015, the Montgomery County Council passed an ordinance restricting the use of certain pesticides for cosmetic purposes throughout the County. The Supreme Court held in 1991 that the principal federal law governing pesticides permits such local legislation. Wisconsin Public Intervenor v. Mortier, 501 U.S. 597 (1991). Here, we are asked to decide whether the County’s legislation is impliedly preempted or in conflict with Maryland’s Agriculture Article. We conclude that the ordinance does not run afoul of State law. Because the Circuit Court for Montgomery County found otherwise, we reverse both its injunction and declaratory judgment, and remand for an entry of a new declaratory judgment declaring the validity of the County ordinance. To briefly summarize, we principally ground our decision on the following:

 1) State law does not expressly preempt local government regulation of pesticides;

 2) Following a 1985 published opinion of the Attorney General which said

that State law did not impliedly preempt local pesticide regulation, 70 Md. Att’y Gen. Op. 161 (1985), and the U.S. Supreme Court’s 1991 decision in Mortier that federal law also did not preempt local regulation, the pesticide industry unsuccessfully sought passage of preemptive legislation in 1992, 1993, and 1994. In full recognition of existing local pesticide ordinances, the members of the House of Delegates by floor vote rejected each of the bills that sought to preempt more stringent local regulation. This “strongly suggests” under the Amendment Rejection Theory that there was no legislative intent to authorize or recognize preemption. Allied Vending, Inc. v. City of Bowie, 332 Md. 279, 304 (1993). No piece of legislation enacted subsequently undercuts that conclusion;

 3) For decades, Maryland’s Chesapeake and Atlantic Coastal Bays Critical Area Protection Program has authorized certain counties to regulate pesticides within the Critical Area without any record of chaos and confusion for multi-tiered regulation;

 4) Despite the existence of a comprehensive federal statute desirous of “uniformity” of regulation, the Supreme Court said that federal law did not regulate pesticides “with[] regard to regional and local factors like climate, population, geography, and water supply” or oust local regulation with respect to such matters. Mortier, 501 U.S. at 614-15;

  5) Probably less comprehensive than federal law, see 501 U.S. at 613, Maryland’s pesticide statutes also reference uniformity with federal legislation. This is best regarded as an aspirational goal, rather than an obstacle to local legislation. The language of State law and enactments of the General Assembly would authorize broader regulation than federal law both generally and specifically;

  6) There is no pervasive administrative enforcement of State pesticide statutes by the Maryland Department of Agriculture, which receives federal funds to enforce federal law in Maryland and which has opposed tougher pesticide controls as “anti-agriculture”; and

  7) Appellees’ contentions and the circuit court’s conclusion that the County ordinance frustrates the purposes of State law run counter to County Council of Prince George’s County v. Chaney Enters. Ltd. P’ship, 454 Md. 514, 541 n. 19 (2017) (Frustration of purpose has never been applied to resolve a conflict between State and local law).

By passing the Healthy Lawns Act, 52-14, the Montgomery County Council acknowledged growing demand within the community for natural and organic lawn care practices and compatible products. These cost-effective lawn care methods have been shown to eliminate the need for toxic pesticide use through improvements in soil biology that support more resilient plants. Pro-pesticide plaintiffs challenging the restrictions were led by Complete Lawn Care, and supported by the pesticide industry lobby group, Responsible Industry for a Sound Environment (RISE).

Communities across the U.S. are considering legislation similar to Montgomery County. In states that preempt, ordinances are focused on the management of public lands within the jurisdiction. See model ordinance, as adopted by the City of South Portland, Maine, here.

Beyond Pesticides’ Map of U.S. Pesticide Reform Policies lists over 150 communities in 23 states that restrict chemical pesticide use. In Maine, over 20 policies address both public and private pesticide applications. Eight of ten Canadian provinces, and over 170 Canadian municipalities have laws with a similar structure to Montgomery County’s Healthy Lawns Act.

(Beyond Pesticides, May 2, 2019) Researchers have documented an increase in food and drinking water residues of neonicotinoids, insecticides linked to breast cancer. Using the Pesticide Data Program (PDP), 1999-2015, of the U.S. Department of Agriculture, the researchers identified near-peak detection frequencies in 2015, after a decline from 2008-2013. Imidacloprid remains the most common neonicotinoid detected across imported commodities, while the neonicotinoids clothianidin, thiamethoxam, acetamiprid, and flonicamid are replacing imidacloprid in domestic production. Authors note that these newer neonicotinoids are potentially more toxic than imidacloprid, raising concerns for understudied human health and environmental impacts.

The study, Trends in neonicotinoid pesticide residues in food and water in the United States, 1999–2015, published in the journal Environmental Health, finds the highest detection frequencies for neonicotinoids in drinking water, with 30% of treated drinking water turning out positive for imidacloprid in 2011. Certain fruits and vegetables are also frequently contaminated by neonicotinoids, with detection frequencies ranging from 20% to as high as 57% in the case of imidacloprid on cauliflower.

While the study points to specific fruits and vegetables as posing higher risk, the main message reaches beyond individual commodity or individual neonicotinoid results. Authors uncover a systematic increase in detection of neonicotinoid residues across the board from 2014-2015, including domestic increases in newer neonicotinoids with potentially higher toxicity than imidacloprid. Critically, neonicotinoid residues are frequently detected in combination, with potential for synergistic interaction. Among baby food samples, for example, authors find 13% of apple sauce samples analyzed contain two or more neonicotinoids. Some of the findings include cherries (45.9%), apples (29.5%), pears (24.1%) and strawberries (21.3%) for acetamiprid; and cauliflower (57.5%), celery (20.9%), cherries (26.3%), cilantro (30.6%), grapes (28.9%), collard greens (24.9%), kale (31.4%), lettuce (45.6%), potatoes (31.2%) and spinach (38.7%) for imidacloprid.

Beyond its link to hormone-dependent breast cancer, neonicotinoids are most infamous for their well-documented role in driving mass pollinator declines. However, pollinators are far from the only victims of ubiquitous neonicotinoid contamination. In a recent avian risk assessment, EPA scientists found that neonicotinoids present in treated seeds exceeds the agency’s level of concern for certain birds by as much as 200-fold. A 2017 study by researchers at the University of Saskatchewan confirmed that tiny amounts of neonicotinoids – the equivalent of just four treated canola seeds, for example – are enough to cause migrating songbirds to lose their sense of direction and become emaciated. Recent research uncovered the endocrine-disrupting health impacts of imidacloprid on white-tailed deer, adding to the concern of the same effect in humans.

Because neonicotinoids persist in soil and easily become airborne, the chemicals spread far beyond target crops and can contaminate nearby plants, soil, and water, thus posing far-reaching threats to wildlife. An EPA aquatic risk assessment for imidacloprid, released in 2017, found that imidacloprid threatens U.S. waterways, with significant risks to aquatic insects and cascading effects on aquatic food webs. Neonicotinoids contaminate over half of urban and agricultural streams across the U.S. and Puerto Rico, according to a report by the U.S. Geological Survey (USGS) that expands on a previous study finding the chemicals in Midwest waterways.

In keeping with these broad contamination trends, authors of the present study uncover a disturbing degree of neonicotinoid prevalence in commonly consumed fruits and vegetables, as well as drinking water. And, as authors note, “The presence of multiple neonicotinoids on single commodity samples raises concerns about cumulative exposures and risks. US EPA has not conducted a human health cumulative risk assessment for neonicotinoids per requirements under Food Quality Protection Act (FQPA) for determining tolerance levels for these pesticides.”

While neonicotinoid residues are on the rise, USDA’s testing methods seem to be declining in sensitivity. Authors note that the limit of detection (LOD), which is the lowest amount of a pesticide that can be detected given technology limitations, has surprisingly increased for certain neonicotinoids and commodities. The LOD for imidacloprid in broccoli, for example, increased by a factor of more than 300 from 2008 to 2014, marking a 300x decrease in sensitivity of testing. This decrease in sensitivity runs contrary to scientific integrity, which typically calls for increased detection sensitivity as technology improves. Authors note that higher LODs mean that fewer samples will be categorized as positive for residues, thus artificially depressing detection frequencies.

As authors emphasize, there is a serious need for more study of the health effects of neonicotinoids and, in particular, newer products with potentially higher toxicity to non-target organisms. While new biomonitoring technologies are in development, currently there is no method for detecting neonicotinoids or their metabolites in biological samples. This lack of technology, in combination with questionable limitations of USDA data collection methods, leaves data gaps that make the conclusion of the study less conclusive than might be desired. Study authors sign off with more questions than answers, and propose that future research applying more sensitive methods and new human health assessment technologies are needed to fully understand the implications of their findings.

Beyond Pesticides holds the position that the current lack of rigorous testing of co-exposures and biomonitoring poses unacceptable threats to human health and the environment. It is our firm stance that organic methods are the only way to guarantee adequate protection.

(Beyond Pesticides, May 1, 2019) Evidence of the dangers of glyphosate continues to mount: researchers at Washington State University have identified, in research that exposed pregnant rats to the compound, significant disease and pathology in subsequent generations. The rats were exposed, from day 8 through day 14 of gestation, to half the observable adverse effect level (NOAEL) of glyphosate. Although this study found negligible impacts on the pregnant rats themselves or on their first-generation offspring, dramatic increases in incidence of pathology showed up in the two subsequent generations, including reproductive (prostate and ovarian) and kidney diseases; obesity; and birth anomalies.

The study, published in the journal Scientific Reports (an open access, multidisciplinary journal from Nature Research), and conducted by Michael Skinner, Ph.D. and five colleagues, is the first to assess the potential transgenerational impacts of glyphosate in mammals. Its results point to an emerging frontier in assessing the risks of glyphosate and other toxic chemicals, and add to the urgent and growing demand that the use of this particular toxic — and pervasive — pesticide be halted.

The research team was interested in looking at possible transgenerational impacts of glyphosate in part because of its ubiquity: it is one of the most commonly used pesticide compounds worldwide, representing 72% of pesticide usage worldwide, and is the active ingredient in Monsanto’s (now Bayer’s) infamous herbicide, Roundup. Dr. Skinner and his team refer to their work as an investigation of “generational toxicology” — a framework that examines exposure impacts on generations beyond that of the exposed subjects. The researchers indicate that they have seen such impacts subsequent to exposures to pesticides, fungicides, the herbicide atrazine, DEET (an insecticide: N,N-diethyl-meta-toluamide), BPA (bisphenol A, an endocrine disruptor), and jet fuel.

Such transgenerational impacts are understood to be functions of distortions in DNA — the epigenetic reprogramming of the germline (egg and sperm), or epimutations. Epigenetic changes result in genes being turned on and off, often in response to environmental factors, such as exposure to toxic chemical compounds. In the subject investigation, researchers saw a 30% incidence of prostate disease in third-generation (3G) males, which is three times the rate found among the study’s controls. Among 3G females, there was a 40% incidence of renal disease, representing a fourfold rate compared with controls. More than one-third of 2G females had failed pregnancies, and 40% of 3G males and females were obese.

Three of the researchers — Eric Nilsson, Ph.D., Ingrid Sadler-Riggleman, Ph.D., and Michael Skinner, Ph.D. — wrote a paper, published in 2018 in Environmental Genetics, titled “Environmentally induced epigenetic transgenerational inheritance of disease.” In the abstract, the co-authors explain the phenomenon: “Ancestral environmental exposures such as toxicants, abnormal nutrition or stress can promote the epigenetic transgenerational inheritance of disease and phenotypic variation. These environmental factors induce the epigenetic reprogramming of the germline . . . . epimutations [that] can in turn increase disease susceptibility of subsequent generations of the exposed ancestors. A variety of environmental factors, species and exposure specificity of this induced epigenetic transgenerational inheritance of disease is discussed with a consideration of generational toxicology. The molecular mechanisms and processes involved in the ability of these inherited epimutations to increase disease susceptibility are discussed. In addition to altered disease susceptibility, the potential impact of the epigenetic inheritance on phenotypic variation and evolution is considered. Observations suggest environmentally induced epigenetic transgenerational inheritance of disease is a critical aspect of disease etiology, toxicology and evolution that needs to be considered.”

The researchers in the 2019 study conclude that “generational toxicology” represents a new lens or framework that, they recommend, should be integrated into any assessment of the risks of pesticides and other toxins in the chemical and materials streams. Current toxicological assessment protocols examine only impacts in individual exposed organisms; impacts on future generations are not assessed. The research team writes, “The ability of glyphosate and other environmental toxicants to impact our future generations needs to be considered, and is potentially as important as the direct exposure toxicology done today for risk assessment.”

Beyond Pesticides has covered the relationship of glyphosate (and the adjuvant ingredients in formulations) to cancer, endocrine disruption, reproduction, and renal and hepatic damage, not to mention its toxicity to fish and other aquatic organisms. Health impacts of glyphosate have been the subjects of numerous studies; conclusions from these studies have been, broadly speaking, all over the map.

The IARC (International Agency for Research on Cancer) in 2015 classified glyphosate as a carcinogen, for example, only to see that conclusion challenged by an EPA Expert Panel the next year. Other studies have shown links between use of the compound and a variety of health impacts, as noted previously. As the co-authors of the subject study note: “A mixture of studies exist showing no direct exposure effects versus induced pathologies. An increasing number of recent published studies suggest a potential risk of direct glyphosate exposure. Regulatory agencies consider the herbicide to be minimally or not toxic.”

In the past few months, two other investigations have come out of Washington State alone. A February 2019 University of Washington study found that glyphosate increased the risk of non-Hodgkin lymphoma by as much as 41%; and a December 2018 Washington State University study determined that Washington residents living nearby to areas treated with the herbicide are one-third likelier to die prematurely from Parkinson’s disease. A February 2018 meta-analysis of studies on glyphosate suggested “a compelling link between exposures to GBH [glyphosate-based herbicides] and increased risk of NHL [non-Hodgkins lymphoma].

As momentum increases across sectors — legal, business insurance and commercial, scientific, et al. — toward reducing or eliminating the use of glyphosate, Beyond Pesticides continues to call for a comprehensive ban on the use of the toxic compound, and a transition to the organic agricultural practices that would obviate much of the perceived “need” for chemical controls.

(Beyond Pesticides, April, 30, 2019) According to the latest blog post from pesticide industry propagandist Henry I Miller, the pollinator crisis either a) is not occurring; b) is not a problem; or, c) caused by varroa mites, pathogens, and habitat loss. Notwithstanding outlandish assertions that there is no pollinator crisis, new research is further undermining the long-held industry claim that it is mites and disease alone, and not pesticides that are harming pollinator populations. Published in the journal Scientific Reports by a team of Canadian scientists, this research finds that realistic exposure to neonicotinoid insecticides impairs honey bees ability to groom mites off of their bodies and increases infection with a disease known as deformed wing virus (DWV).

“When bee colonies began to collapse years ago, it became clear there wasn’t just one factor involved, so we were interested in whether there was an interaction between two of the main stressors that affect bees: varroa mites and a neurotoxic insecticide, clothianidin,” said Nuria Morfin Ramirez, PhD, at the University of Guelph, Canada.

Dr. Ramirez and her team exposed honey bees to a range of different concentrations (low, medium, high) of the neonicotinoid clothianidin, with some bees receiving combined stressors of the insecticide and a mite infection. A population unexposed to either mites or the insecticides acted as a control. After exposure, researchers measured grooming intensity, and the number of genome copies of DWV within affected honey bees’ RNA.

At the lowest dose of clothianidin given, there was the steepest decline in the number of grooming bees. This same group also showed increased levels of DWV compared to control bees. When exposed to clothianidin doses in the mid-range of treatment, honey bees showed no changes in their grooming behavior. But when varroa mites were introduced to this same population, grooming levels dropped by 1.4 times.

“This study highlights the importance of reducing stressors that bees are exposed to, to reduce the risk of disease and consequently colony mortality,” said study coauthor Ernesto Guzman, PhD. “What we found was a complicated interaction between the mite and the pesticide that decreased the proportion of bees that groomed intensively, and affected genes associated with neurodegenerative processes,” Dr. Morfin continued.

As the author’s indicate, this is the first study to look directly at how neonicotinoid exposure impacts honey bee grooming behavior. But it is not the first study to show how neonicotinoids may be weakening honey bees, and making them more vulnerable to parasites and disease. A 2013 study found that low level exposure to neonicotinoids and other pesticides from crop pollination made honey bees more susceptible to the gut parasite, Nosema ceranae.

A 2015 report by the European Academies Science Advisory Council found, “Several studies have demonstrated synergistic effects of neonicotinoid residues with bee parasites and viruses. Some effects are behavioral (e.g. blocking the ability of bees to sterilize the colony and their food). Others appear related to limiting the immune response leading either to earlier infection or to increased mortality from infection. Very recent work has shown that the limitation of the immune response after exposure to neonicotinoids can promote viral replication, allowing covert infections to become overt. Such effects reduce honey bee survival and increase developmental deformities. In view of the emphasis placed by some reviewers on assigning honey bee losses to diseases and parasites, this is a critical issue.”

Advocates aiming to protect pollinators have never dismissed the devastating losses reported by beekeepers, data on decline in wild bee, monarch, and bird populations, or shied away from the likelihood of synergistic effects from multiple stressors being an important part of the equation in saving pollinators. But there can be no doubt, based on the science accumulated over the last decade and a half, that neonicotinoids, and by extension the broad range of pollinator toxic pesticides, are critical factors in the cause of pollinator declines. Not only that, but compared to a number of other stressors, including climate change and habitat fragmentation, they are one of the most straightforward and achievable to address. After all, these chemicals lack any real monetary benefits for farmers.

But many lawmakers have been comfortable sitting on their hands as the crisis continues to unfold. It is clear that U.S. federal regulators are falling down on the job of protecting the environment, crop pollination, and beneficial insects in general. As a 2016 GAO report found, both the U.S. Department of Agriculture and the Environmental Protection Agency are not doing enough to protect pollinator populations.

We have a chance to address systemic neonicotinoid insecticides, and the broad range of pesticides that harm bees and other pollinators, by joining with lawmakers that understand the magnitude of the crisis. Currently, the Saving America’s Pollinator’s Act has 44 cosponsors committed to reversing pollinator declines. See the list here, and if your Congressional representative isn’t there, make sure to send them a message, and follow up with a phone call to their office.

(Beyond Pesticides, April 29, 2019) It Is Time to Stop the Attack on Organic and Protect the Family Farmers Who Safeguard the Earth and Our Health.

Listening to and talking with dairy farmers at the National Organic Standards Board meeting in Seattle last week, it is clear that organic consumers and farmers everywhere need to rise up to protect the standards of organic. This is the only way we can ensure a livable future—clean air, water, air, and a reversal of the climate crisis and the insect apocalypse. While there are numerous problems with the current administration’s attack on organic across the board—and we are focused on the range of problems, dairy is a good place where we must join together before more organic family farmers literally go out of business. Organic dairy is the first place families look to protect their children.

Tell USDA and your members of Congress to protect organic family farmers who safeguard the environment and animal welfare.

As a result of abuses in government management of organic, we are seeing an attack on organic that can be corrected with the adoption of proposed rules that have been waiting to be adopted—the Origin of Livestock and the Access to Pasture rules. Without these rules, former Wisconsin dairy farmer, Jim Goodman, wrote in the Washington Post last December:

When six dairy farms in Texas feed their thousands of cows a diet of organic grain and stored forage, with no discernible access to a blade of grass, they end up producing more milk than all 453 organic dairy farms in Wisconsin combined. Then they ship it north, undercutting our price. We can’t make ends meet and are forced out of the business. We played by the rules, but we no longer have a level playing field.

The Real Organic Project has explained the situation as follows:

The crux of the problem with the current rule for origin of dairy livestock is that there exists a two-track system for conversion of conventional dairy animals to organic. One track is that a whole herd can be converted to organic over a 12-month period, but thereafter no animals can be transitioned from conventional to organic on that farm. The other track is that for herds that did not use the one-time conversion, producers can continuously transition dairy animals into organic over time, using a 12-month conversion period for each animal transitioned.

A further complication is that some NOP accredited certifying organizations allow farms to continuously transition dairy cows from conventional to organic and other certifying organizations do not allow that.

Numerous public comments over the years of rulemaking have pointed out that this two-track system creates an uneven playing field for organic dairy producers. The National Organic Program proposed rule of April 28, 2015 would have fixed that problem by removing the option for an open-ended conversion of conventionally raised dairy animals to organic, as called for by an overwhelming majority of public comments. USDA has never finalized that proposed rule on the origin of livestock, putting family farmers in jeopardy. Furthermore, the Western Organic Dairy Producers Association has called for the elimination of the one-time transition of dairy herds from conventional to organic, maintaining that there are now enough organic dairy animals in the organic market to grow the organic dairy industry.

According to the Organic Farmers Association, consistent enforcement of the access to pasture rule, including identification of high risk dairy operations such as those with more than 1000 milking and dry cows, is needed to meet USDA’s Farm Bill and Legislative Principles priority to “Protect the integrity of the USDA organic certified seal and deliver efficient, effective oversight of organic production practices to ensure organic products meet consistent standards for all producers, domestic and foreign.”

Tell USDA and your members of Congress to protect organic family farmers who safeguard the environment and animal welfare.

Letter to Members of Congress

 It is way past time for the U.S. Department of Agriculture to protect organic family farmers and consumers with rules to protect organic integrity –the Origin of Livestock and the Access to Pasture rules. Without consistent enforcement of these rules, former Wisconsin dairy farmer, Jim Goodman, wrote in the Washington Post, last December:

I agree with the Organic Farmers Association (OFA) recommendation that the National Organic Program (NOP) strengthen its enforcement of the Access to Pasture rule by immediately instructing certifying agents to identify high risk dairy operations as those with over 1000 milking and dry cows and instructing its agents that they need to meet the following requirements for the certification of high risk dairy herds:

• Certification file review staff and organic inspectors must have documented training and experience in livestock nutrition and grazing on organic dairies with over 1,000 milking and dry cows.
• A calculation matrix will be required for verification of meeting the grazing requirement which includes the following parameters: average animal weight, individual and verifiable unique identification of each animal, milk production, daily dry matter requirement, daily non-pasture dry matter consumption, acres of pasture, forage yield of pasture, and maximum distances cows walk to pasture.
• As stated in the regulation, dry matter intake “shall be calculated as an average over the entire grazing season for each type and class of animal;” thus, for example, dry matter intake of milking cows cannot be averaged with dry matter intake of dry cows.
• Certifiers must conduct two inspections during the grazing season, one announced and one unannounced.

On behalf of farmers and consumers, please urge the Secretary of Agriculture to adopt the Origin of Livestock and enforce the Access to Pasture Rule. To protect the livelihood of organic farmers and the integrity of the organic label, this is urgent.

Thank you.

Youth researchers of the COSECHA Study.

(Beyond Pesticides, April 26, 2019) Research by the youth participatory action team of the CHAMACOS of the Salinas Evaluating Chemicals in Homes and Agriculture (COSECHA) reveals that teenagers in the Salinas Valley, California are routinely exposed to concerning levels of multiple toxic pesticides, several of them known endocrine disruptors. In an interview with Kion News, COSECHA research director Kimberly Parra remarked that the study is especially important because teenagers are in a stage of rapid reproductive development. As the study authors emphasize, it is their developmental stage that makes teenagers more vulnerable to the effects of endocrine disrupting pesticides, with potentially devastating consequences for lifelong health.

The COSECHA study quantifies exposure to 72 pesticides, captured through volatile-trapping silicone wristbands, across 97 teenage girls living in various areas of the Salinas Valley region. Of the 72 pesticides analyzed, authors report that subjects are exposed to as many as 20 and an average of 8 pesticides over one week of routine indoor and outdoor activity. Given the well-documented dangers of pesticide co-exposures, these multiple-exposure findings are particularly concerning.

Ranking the highest for prevalence among the studied pesticides is fipronil sulfide, a breakdown product of the insecticide fipronil, detected in 86.6% of the analyzed wristbands. Fipronil is a known endocrine disruptor and has been shown to disrupt thyroid function. It is classified by the U.S. Environmental Protection Agency (EPA) as a Group C (possible human) carcinogen. The World Health Organization (WHO) regards fipronil as “moderately toxic” to humans, and can, in large quantities, damage kidney, liver or thyroid gland.  As the authors note, fipronil “has exhibited oncogenicity and neurologic toxicity in animal studies,” raising concerns for the 84 Salinas Valley girls whose wristbands turned out positive for the toxin, and for the 86.6% of children population-wide whose routine exposure levels the study reflects.

Among their findings, perhaps most concerning is the degree to which discontinued pesticides – including some that have been out of use for nearly five decades – are still detected at high frequency. DDE, a breakdown product of the long-banned organochlorine insecticide DDT, was detected in 55.7% of the wristbands.

While their findings carry an often repeated and all-too-often ignored message, the COSECHA Study has something distinct to offer – its community-based approach. A team of ten youth researchers participated in all aspects of the study, from devising research questions to surveying subjects, analyzing results, and interpreting their significance to the community.

The seeds of the COSECHA Study were first planted in 1999, when researchers at Berkeley’s Center for Environmental Research and Children’s Health embarked on what is now the longest running longitudinal birth cohort study of its kind – the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS) Study. Titled after the term for “little children” in Mexican Spanish, the CHAMACOS program seeks to link maternal, prenatal, and childhood pesticide exposures to health outcomes among children living in California’s Salinas Valley. By now, CHAMACOS has tracked the health outcomes of over 800 children and published more than 150 papers on their public health findings.

But to some, the most important aspect of the program cannot be captured in numbers. The heart of CHAMACOS and, researchers attest, the reason for its long tenure, is the program’s dedication to community-based participatory research.

For one group of “CHAMACOS babies” especially, the project became more than just a regular check-in. In 2015, a group of Berkeley researchers aiming to involve youth in participatory action research had a revelation. “We went, wait a minute,” remarked Kim Harley, Ph.D. in an interview with Ensia. “The CHAMACOS kids are 14 years old now and we’re looking to enroll a bunch of 14-year-olds.” Together with the Salinas Valley Health Clinic (Clinica de Salud del Valle de Salinas), Berkeley researchers began to recruit CHAMACOS study subjects to join a Youth Council and effectively flip their roles, from the observed to the observers.

Within the year, a group of roughly one dozen original CHAMACOs participants had joined the CHAMACOS Youth Council and a new project was born: “Chamacos of Salinas Evaluating Chemicals in Homes & Agriculture,” or COSECHA, Spanish for harvest. These latest findings, and even more so the process young Salinas residents went through to arrive to the point of publication, can truly be thought of as the harvest of the CHAMACOS project.

(Beyond Pesticides, April 25, 2019) As reported by Mother Jones, the New York Times (NYT) published, on April 6, a distressing report about a deadly fungus that has been advancing steadily across the world during the past five years. Candida auris is an emerging fungal pathogen that threatens those with compromised or immature immune systems, such as infants, the elderly, people taking steroids for autoimmune disorders, diabetics, those undergoing chemotherapy, and even smokers. Nearly half of those who contract a C. auris infection die within 90 days. One of the factors making this fungus so deadly is that it has developed resistance to existing antifungal medicines, with 90% of infections resistant to one drug, and 30% to two or more. As is true for resistant bacteria, culprits in C. auris’s development of resistance may be the overuse of antifungal medications in health care and overreliance on fungicides in agriculture.

The Centers for Disease Control and Prevention (CDC) has added C. auris to its list of pathogens considered “urgent threats.” It is an “emerging fungal pathogen,” meaning that the incidence of infection has been increasing across multiple countries since it was first recognized in 2009 in Japan (although a different strain had been identified in South Korea in 1996). It has recently shown up in hospital units and nursing homes in Venezuela, Colombia, Panama, Spain, France, Britain, Germany, India, Pakistan, Saudi Arabia, Russia, China, Australia, Kenya, South Africa, Canada, and now, cases have been confirmed in New Jersey, New York, and Illinois; U.S. cases thus far have been primarily in nursing homes and other long-term care facilities. C. auris is impervious to major antifungal medications, and is difficult to eradicate in patient surrounds, never mind in human bodies.

After an elderly man at the Brooklyn branch of Mount Sinai hospital contracted the fungal infection — and eventually died — the hospital launched an effort to eradicate the pathogen from his hospital room. As the NYT reported, “Tests showed it was everywhere in his room, so invasive that the hospital needed special cleaning equipment and had to rip out some of the ceiling and floor tiles to eradicate it. ‘Everything was positive — the walls, the bed, the doors, the curtains, the phones, the sink, the whiteboard, the poles, the pump,’ said Scott Lorin, M.D., the hospital’s president. ‘The mattress, the bed rails, the canister holes, the window shades, the ceiling, everything in the room was positive.’”

Echoing the development of resistance in bacteria, there have lately been resistant fungi showing up in hospitals and labs, adding to the already considerable worry in the medical community about how to treat people who contract infections caused by resistant pathogens. Matthew Fisher, Ph.D, a professor of fungal epidemiology at Imperial College London, has said, “It’s an enormous problem. We depend on being able to treat those patients with antifungals.” Fungi, just like other organisms, adaptively exploit genetic mutations to defend against what would kill them — in this case, antifungal medications.

Despite admonishments from researchers and leaders in global healthcare to rein in the use of all antimicrobial pharmaceuticals (antibiotics and antifungals, in particular), the medical community has continued to overuse them. But medical overuse may not, by a long shot, be the only culprit: farmers across the globe rely heavily on, essentially, the same chemical compounds to fight pathogens — on crops and in livestock — that medicine depends on when those pathogens invade the human body. These important tools in fighting infections have been used to excess for non-medical purposes: antibiotics for prophylaxis and for accelerated weight gain in farm animals, and fungicides on crops to prevent certain kinds of blight and rot. In addition, there are “crossover” uses: several fungicides are also registered for managing bacterial diseases in fruits, vegetables, grains, and other food crops.

In research published in May 2018 in the journal Science, Dr. Fisher, et al. noted that, “The recent rate of emergence of pathogenic fungi that are resistant to the limited number of commonly used antifungal agents is unprecedented. The azoles, for example, are used not only for human and animal health care and crop protection, but also in antifouling coatings and timber preservation. The ubiquity and multiple uses of azoles have hastened the independent evolution of resistance in many environments. One consequence is an increasing risk in human health care from naturally occurring opportunistic fungal pathogens that have acquired resistance to this broad class of chemicals.”

Mother Jones reports that one subset of azoles (systemic antifungal agents), the triazoles, are the most commonly used category of fungicides (antifungals), comprising more than 25% of all fungicides used in European agriculture. Agricultural use of triazoles has spiked, in the U.S., to a 2015 level of 3,000 metric tons. A causal link between fungicides used in agriculture and C. auris has not been proven, but U.S. and European scientists suspect that such use may have been a “trigger” for its emergence.

Dutch researcher Jacques Meis, M.D., Ph.D. believes that drug-resistant fungi are developing thanks to heavy use of fungicides on crops. He first paid attention to the resistance–agricultural use link when a patient in the Netherlands died in 2005 from the fungus Aspergillus, which proved resistant to the antifungal itraconazole — that compound being a virtual copy of the azole fungicides used worldwide to treat crops, and accounting for more than one-third of all fungicide sales. Research in 2013 demonstrated a link between areas where azole fungicides are used and the flourishing of the Aspergillus fungus, showing up in 12% of Dutch soil samples. In 2018, Dr. Meis visited the CDC to talk about his conviction that a similar thing is happening with C. auris: azoles created an environment so hostile that fungi are evolving, with resistant strains — such as C. auris —surviving and “thriving.”

According to the NYT, the CDC’s Tom Chiller, chief of the Mycotic Diseases Branch, who calls C. auris “a creature from the black lagoon,” also believe that its resistance and “explosion” may have “benefited from the heavy use of fungicides.” According to Mother Jones, Dr. Chiller “reiterated the possibility of a link. With triazole fungicides killing fungi over large swaths of farmland, ‘the ones that are going to survive are the ones that are resistant — and they’re going to flourish. And so you could see how that could select for a relatively rare Candida like Candida auris.’”

The issue of resistance and its causes is not well understood by much of the public, perhaps in part because of science illiteracy, but also in part, as the NYT reports, “because the very existence of resistant infections is often cloaked in secrecy. With bacter[ial] and fung[al infections] alike, hospitals and local governments are reluctant to disclose outbreaks for fear of being seen as infection hubs. Even the C.D.C., under its agreement with states, is not allowed to make public the location or name of hospitals involved in outbreaks. State governments have in many cases declined to publicly share information beyond acknowledging that they have had cases.”

Even serious outbreaks in England (50 cases in one hospital in 2015) and Spain (85 cases, reported in 2018) were kept on the down low by hospitals worried about institutional reputation and that such reports are “bad for business.” Some in the healthcare industry defend the hush on such outbreaks of C. auris infections, saying that disclosure frightens patients and alarms the public about a situation that healthcare professionals do not have effective ways of managing. But patients and healthcare advocates find this attitude maddening. Says Kevin Kavanagh, M.D., a Kentucky doctor and chair of Health Watch USA (a nonprofit that promotes healthcare transparency, quality, and affordability), “Why the heck are we reading about an outbreak almost a year and a half later — and not have it front-page news the day after it happens? You wouldn’t tolerate this at a restaurant with a food poisoning outbreak.” In addition, the difficulty of managing C. auris can unnerve facility staff members, given its significant lethality and the challenges of eradication from patient surrounds.

The concern about human infection by antifungal-resistant fungi is a distinct echo of the mounting worry about infection by antibiotic-resistant bacteria. Beyond Pesticides has chronicled developments in the emergence of both fungicide resistance and pesticide/antibiotic resistance. The burgeoning resistance problem derives, in part, from the intensive use of pesticide products (including insecticides, herbicides, fungicides, and others) in plant and animal agriculture. Use of these compounds inevitably drives the problem: as Beyond Pesticides wrote last year in its journal, Pesticides and You, “Broadscale and repeated use of a pesticide sets in motion the factors that drive the evolution of resistance in the target pest. Those that are not killed by the pesticide pass down the genes that allowed them to survive, perpetuating a toxic cycle.”

The agrochemical industry’s response to the development of resistance has typically been to develop new compounds to target the same pest or bacterial or fungal problem, and/or to “layer” use of multiple pesticides, sometimes causing actual increases in the amounts of pesticides used. Conventional farming is so extensively shaped by what these companies develop and recommend that many farmers, faced with a pest problem on which existing pesticides have become ineffective, will simply move to the next chemical “fix” that industry develops. This dynamic is a recipe for ecological entropy and not a solution. Chemical interventions to “control” pests of any sort, beyond all the potential toxicity issues, fundamentally cause imbalances in micro and macro ecological systems.

When humans use toxic synthetic chemicals to protect “systems” that violate natural and ecological laws — such as monocrops (think huge fields of commodity corn, soy, wheat, cotton, et al.), or great swaths of grassy lawns — the natural predators that exist in ecosystems can be destroyed or challenged, reducing the balanced and cyclical nature of predator and prey. (In nature, populations of all organisms wax and wane, with available food sources and level of predation.) Chemical inputs in agriculture reduce the biodiversity that keeps these systems functional; pesticide use begets more pesticide use as part of what is known as the “pesticide treadmill.”

Fraught as it is with negative impacts on human and environmental health, including the mounting resistance issues, chemically intensive agriculture should be understood as a sign of the ineffectiveness of conventional, chemical approaches to pest control. Organic agricultural practices, which proscribe the use of harmful pesticides, support biodiversity, intact ecosystems, and human health. Organic agriculture seeks to prevent pest problems by creating healthy agroecosystems. Adoption of organic approaches diminishes the resistance problem and can potentially help preserve important antibiotic and antifungal medicines for treatment of human infection.

Be a part of the critical shift from chemical agriculture to organics. Learn more about organic agriculture, advocate for it, and “vote” for organics by creating market demand for organic food.

(Beyond Pesticides, April 24, 2019) On April 19, the U.S. Court of Appeals for the 9^th Circuit ordered the U.S. Environmental Protection Agency (EPA) to provide a justification for why chlorpyrifos, a neurotoxic insecticide commonly used in agriculture, should remain in the U.S. market. The EPA has 90 days to comply.

Chlorpyrifos has been linked to damaging and often irreversible health outcomes in workers, pregnant women, and children. Low levels of exposure early in life can lead to increased risk of learning disabilities including lowered IQ, developmental delay, and attention deficit/hyperactivity disorder (ADHD). Farmworkers and their children are disproportionately affected by the use of this chemical because they are exposed at work, home, and even at school.

“While we are moving forward, the tragedy is that children are being exposed to chlorpyrifos, a pesticide science has long shown is unsafe,” said Earthjustice Attorney Patti Goldman in a statement. “We hope Trump’s EPA finally decides to protect the future of countless children and the health of millions of farmworkers.”

The battle against chlorpyrifos has been long and drawn out, though there has been significant movement in the last few months. Beyond Pesticides has put together a brief timeline of events:

A Chlorpyrifos Timeline:

2001-2017

• 2001, EPA negotiates cancellation of chlorpyrifos for residential use.
• 2007, Pesticide Action Network North America (PANNA) and Natural Resources Defense Council file petition requesting EPA revoke all tolerances for chlorpyrifos.
• 2015, Obama administration proposes revocation of all tolerances for chlorpyrifos.
• 2016, EPA’s revised human health risk assessment does not change the proposal to ban chlorpyrifos. Donald Trump is elected president.
• 2017, Scott Pruitt reverses order. A coalition of environmental groups led by Earthjustice promptly sues.

2018

• June 2018, Hawaii becomes first state in U.S. to outright ban chlorpyrifos, effective 2022.
• July 2018, Scott Pruitt resigns amid over a dozen ethics investigations.
• August 2018, Court orders a ban on chlorpyrifos, stating that EPA violated the law. Trump administration quickly appealed the ruling.
• December 2018, Senator Brian Schatz (D-HI) introduces the Prohibit Chlorpyrifos Poisoning Students Act.

2019

• January 2019, Representative Nydia Velásquez (D-NY) reintroduces The Ban Toxic Pesticides Act, H.R.230 which bans the insecticide chlorpyrifos from commerce.
• February 2019, 9^th Circuit Court of Appeals rules to rehear the case regarding chlorpyrifos.
• March 2019
  • Senator Tom Udall (D-NM) reintroduces Protect Children, Farmers and Farmworkers from Nerve Agent Pesticides Act of 2019.
  • Oregon Lawmakers consider House Bill 3058 and Senate Bill 853, nearly identical attempts to ban chlorpyrifos.
  • A set of documents obtained by the Center for Biological Diversity reveal that the Trump administration knew and actively concealed the fact that chlorpyrifos jeopardizes the existence of 1,399 endangered species.
• April 2019
  • Proposed chlorpyrifos ban in Maryland (HB275, SB270) does not pass for the second year in a row.
  • Senator Kirsten Gillibrand (D-NY) introduces Safe School Meals for Kids Act to restrict schools from purchasing or serving any food that contains any amount of detectable chlorpyrifos.

Momentum is growing for better protection from pesticide use. However, beyond single-pesticide bans, the widespread adoption of organic management practices is best for holistic protection of human and environmental health from compounds like chlorpyrifos. Beyond Pesticides has long sought a broad-scale marketplace transition to organic practices, which prohibit the use of all toxic synthetic pesticides.

(Beyond Pesticides, April 23, 2019) “If I can kill this I should get a medal,” Jess Rowland, former Deputy Division Director of the Office of Pesticide Programs at the U.S. Environmental Protection Agency (EPA) told Dan Jenkins, U.S. Agency Lead for Regulatory Affairs at Monsanto, in April 2015. The two were discussing the Monsanto officials’ desire to halt an impending investigation by the U.S. Department of Health and Human Services (DHHS) into the health risks that the weed killer glyphosate poses to the public. But despite the attempts of an apparently corrupt EPA official, earlier this month DHHS’ Agency for Toxic Substances and Disease Registry (ATSDR) released its first draft on the Toxicological Profile for Glyphosate. Top-line findings appear consistent with conclusions made by the World Health Organization’s International Agency for Research on Cancer (IARC) on the carcinogenicity of glyphosate.

Although not officially “killed,” Mr. Rowland’s cozy relationship with Monsanto did lead to a delay in ATSDR’s report, and prompted an EPA Inspector General investigation into potential misconduct.

While Mr. Rowland’s acts were concerning, Monsanto’s attempts to quash this investigation did not stop there. Toxicologist Mary Manibusan is a prime example of the revolving door between industry and the agency that is supposed to oversee it. A long-time EPA employee, Ms. Manibusan worked at the agency for eight years before taking a job in the private sector. As word of an ATSDR report became more concrete, Monsanto reached out to her for her access and influence with ATSDR officials. “Sweetheart – I know lots of people,” Ms. Manibusan told Monsanto scientist Eric Sachs in a text message. “You can count [on] me.”

Mr. Sachs concern? “We’re trying to do everything we can to keep from having a domestic IARC occur w[ith] this group. May need your help.” Ms. Manibusan is now back with EPA as of this month. According to her Linkedin, she is an agency Division Director.

And efforts to suppress ASTDR’s work did not stop there. It appears the pesticide industry tried to insert language into a fiscal appropriations bill that directs ATSDR to “focus on its core mission of assessing hazardous exposures and working with communities, if requested, near toxic waste sites and not agricultural operations.” That attempt was also unsuccessful and the language does not appear in the Consolidated Appropriations Act of 2019.

ATSDR does not make a definitive conclusion one way or another on the carcinogenicity of glyphosate. However, the studies and references analyzed in the report indicate clearly there is strong link between glyphosate and cancer. Of particular note are the three meta-analyses of epidemiological studies reviewed by ATSDR: Schinasi and Leon (2014), Chang and Delzell (2016), and the IARC monograph, which all found “positive associations” between glyphosate exposure and cancer. The Chang and Delzell (2016) study, funded in part by Monsanto itself, downplays in its abstract conclusions that in fact line up closely to the other meta-studies.

Cancer was not the only subject in ATSDR’s review of glyphosate. It also reviewed the effects of the chemical on body weight, pulmonary and cardiovascular health, gastrointestinal affects, neurotoxicity, impacts to the kidney and liver, skeletal system, its endocrine disrupting properties, effects on the immune system, developmental and reproductive systems, and impacts to the eyes and skin. Not all of these health endpoints revealed significant concerns, but the review should bring more attention to non-cancer impacts on the lungs, reproductive system, and the possibility of glyphosate exposure resulting in developmental effects in pregnant mothers.

It is because of the courage of California school groundskeeper Dewayne “Lee” Johnson that the public has access to evidence of Monsanto’s subterfuge around this U.S. public health chemical review process. His ultimately successful litigation against Monsanto for causing his cancer, with a $289 million jury verdict, led to the disclosure of the internal documents and emails cited above.

ATSDR has opened public comments on its glyphosate review through this link.  Although many health endpoints are covered by this review, it is not quite comprehensive and there is room for ATSDR to conduct further evaluation on full-formulation toxicity, the raw data on industry studies (reviewers had access only to EPA summaries of industry-submitted studies), and impacts to the microbiome.

(Beyond Pesticides, April 22, 2019) This Earth Day, please join us in celebrating, propagating, and educating about a misunderstood and beneficial plant: clover. 

Clover:

• Provides your lawn with enough nitrogen to eliminate any need for ecologically hazardous synthetic fertilizers
• Acts as an important food source for declining pollinator populations
• Attracts earthworms and other beneficial soil microorganisms
• Remains green year-round
• Resists drought
• Helps your lawn resist disease

A little history:

“White clover used to be a standard ingredient in every grass seed mix; 75 years ago no one planted a lawn without mixing a little white clover in with the grass seed,” recounts Roger Swain, host of PBS’ The Victory Garden.

After World War II, as the middle class grew and moved to suburban communities, chemicals developed during wartime found new uses on U.S. lawns. Chief among them was 2,4-D – an herbicide originally developed with the intent to wipe out potatoes in Germany and rice crops in Japan in a plan to starve the Axis powers into surrender. While 2,4-D was never used for that purpose, its ability to kill broadleaf plants while sparing grass species made it desirable on the farm for removing weeds around crops like wheat, corn, and rice.

Chemical companies hoped these same characteristics would win over American homeowners, who would simply need one blanket application to rid their lawn of weeds. In 1945, the American Chemical Paint Company released the first residential use 2,4-D herbicide, Weedone, and later in the decade, Scotts packaged its first ‘weed and feed’ product.

Some say that it was not until the 1966 Masters golf tournament’s bright green turf was broadcast on color television that the idea of a monoculture lawn really took hold. Despite clover’s role in the rise of the American lawn, its susceptibility to broadleaf herbicides, like 2,4-D, put it at loggerheads with the new technology, and through aggressive marketing and advertisements, by the 1950s it began to be regarded as a weed.

Clover is a wonderful plant.

Clover is a low-growing, drought-tolerant perennial. There are nearly 250 species of clover in the world. Though red, crimson, and white are the most familiar, it is white, or Dutch, clover that is best suited to be incorporated into turfgrass and lawns. A variety of low growing white clover called microclover can provide all the benefits of clover, while producing fewer flowers and remaining somewhat hidden below the grass.

Bringing clover back into American lawns is predominately a cultural issue. It requires a change in perception about what constitutes an aesthetically pleasing landscape, and education about the ecological benefits and cost-savings that clover can provide. Individuals can press their local government to incorporate grass-clover seed mixes into their public parks and green spaces and inform neighbors of the benefits of doing so. 

Microclover mixed in with grass.

Clover is great for soil.

Contrary to the perception that clover is an eyesore, it helps the lawn remain verdant green during the growing season. As a member of the legume family, clover “fixes” (accumulates) nitrogen from the air through beneficial soil bacteria living in nodules on its roots. Clippings left on a lawn after a mixed grass-clover turf is mowed can provide a significant source of cost-free nitrogen. For many soils and grass types, this is enough to eliminate the need for any additional nitrogen fertilizer applications over the course of the year.

Planting clover in your lawn is a small and easy way to help bolster pollinator populations. 

Recent research finds that clover acts as a food source for a wide range of important pollinator species. A 2014 study published by Larson et al. in the Journal of Insect Conservation on species richness in mixed grass-clover lawns in the Lexington, KY metro area documented over 200 pollinator species over the course of spring sampling, including approximately 21 different species of bees. On average, each lawn contained between 2-12 different pollinator species. City-dwellers tending a small patch of lawn certainly are not doing so in vain, as researchers found species richness to be similar in urban, suburban, and periurban-rural areas.

Rose clover (Trifolium incarnatum).

You can be the change you wish to see in the world.

The beauty of reviving clover on lawns is that every individual with a patch of green space can make a stand. Let the clover already present flower, and don’t be afraid of seeding more. Yes, your lawn will contain small white flowers, and yes, you’ll attract bees to your yard, but you know that’s a good thing for your wallet and the environment, and when your neighbor asks what you’re doing, you’ll be ready to respond.

As you celebrate clover, you can also make the case for restrictions on the use of synthetic herbicides that treat clover as a weed and insecticides that undermine the services the plant provides. Learn more about organic lawn care, and check out our “Tools for Change” page for more info and resources regarding organizing in your community.

Buying seeds:

Dutch White clover is the traditional option to add to turf grass, but you can also have poppies and clover (see picture below) as a cover crop. Many garden centers and hardware stores now carry clover seed, and it can also be purchased online (Here or here, or check out our Pollinator-friendly seed list). DFL organics and EarthTurf are two companies which specialize in grass-microclover seed mixes.

(Beyond Pesticides, April 19, 2019) Flying insects exposed to neonicotinoid insecticides or its breakdown products experience visual impairment and difficulty flying, according to a study published in the journal NeuroToxicology by researchers at the University of Saskatchewan, Canada. While at face value these impacts may sound non-lethal, any loss of fitness in the wild can make flying insects an easier meal for their predators. “Our findings suggest that very low doses of the pesticide or its metabolic products can profoundly and negatively affect motion detection systems that flying insects, such as locusts, grasshoppers and bees, need for survival,” said Jack Gray, PhD, an expert in neural control of animal behavior at the University of Saskatchewan.

Researchers used locusts as proxies for other flying insects, as the visual processing in their brains is easy to track in laboratory settings. Moreover, as study co-author Rachel Parkinson notes, “Bees and other flying insects use similar neural mechanisms to process visual motion,” making the implications of this study applicable to a wide range of other airborne insects.

And rather than simply focus on the effects of exposure to a single active ingredient, researchers also studied whether its breakdown products (metabolites) resulted in similar impairment.

Locusts flight and escape behavior were tested in wild tunnels after exposure to the neonicotinoid imidacloprid and its metabolites at levels likely to be found in the wild (10 parts per billion). Insects were exposed to the same levels of the chemicals in order to test visual functioning to looming stimuli, which essentially mimics response to an object entering the locusts’ field of vision.

The results show that exposure significantly impairs how locusts to respond to visual stimuli. Researchers found that roughly an hour following an initial exposure, most of the insects either were unable to fly or flew very poorly, unable to respond to stimuli or avoid objects in their flight path. Interestingly, the impacts were more pronounced when exposed to the breakdown products of the pesticide than the active ingredient itself. After imidacloprid exposure, 40% could still fly and respond to stimulus, 30% flew poorly, and 30% could not fly an hour after treatment. But with its metabolite 5-hydroxy-imidacloprid, 80% could not fly at all while the remaining 20% flew poorly.

Concern has long surrounded neonics for their propensity to remain in the environmental for months or even years after exposure. Now, it appears that even after an active ingredient has broken down, it may still continue to poison animal life. “Although they are found in the environment, and insects can be exposed to them, metabolites are not typically tested for toxicity. Our results suggest they should be,” said Dr. Gray.

Although locusts are sometimes considered a pest, they are an important part of the ecology of many landscapes and many animals’ diets, and there are profound implications if these results signal effects in other flying insects. “The ability to see movement is crucial not only for avoiding predators, but also for maintaining a steady flight path,” said study coauthor Rachel Parkinson.

It is evident now that the pollinator crisis was only the most visible aspect of what has been characterized by the New York Times as a global insect apocalypse. A study published in on German nature preserves in 2017 found that flying insect biomass had declined by 75% over the last three decades. But in areas where care has been taken to remove pesticides and improve habitat, like Amsterdam, data finds that diversity and abundance is increasing.

Work to emulate those efforts in your own community by getting involved in grassroots advocacy. The more folks that contact their elected officials, attend and speak at local council meetings, and promote healthy, pesticide-free habitats, the better chance we will have at reversing the crisis, or at the least create some resilient, chemical free oases that will help species bounce back or repopulate other areas.

Dung beetle.

(Beyond Pesticides, April 18, 2019) Organic farming promotes natural resistance to common foodborne human pathogens, according to a study that evaluates the benefit of soil organisms. By protecting valuable species of dung beetles and soil bacteria, organic farming systems naturally act to clean up and decompose potentially pathogen-bearing animal feces. While these natural systems suppr

ess pathogens on organic farms, coventional chemical-intensive farms are left with higher levels of fecal residues and are therefore significantly more likely to yield produce carrying such foodborne pathogens as E. coli. The authors emphasize that curbing the spread of common foodborne pathogens could save thousands of lives and prevent millions of illnesses each year.

The study, “Organic farming promotes biotic resistance to foodborne human pathogens,” published in the Journal of Applied Ecology, compares dung beetle populations, soil bacteria diversity, and feces removal rates on 70 organic and conventional broccoli farm fields across the west coast of the U.S. In addition to studying field conditions, authors conducted additional microcosm studies to directly test the effects of dung beetles and soil microbes on the suppression of introduced E. coli.

Results from field analyses show that organic management practices lead to greater biodiversity among dung beetles and soil microbes, which translate to higher rates of feces removal. Microcosm results confirm that by removing fecal matter, the beetles and microbes retained by organic management reduce potential E. coli contamination. These new findings add to the list of ecosystem services unique to organic farms, further bolstering the case for organic as not only an ecological but an economical solution to global food production.

In the context of recently reviewed insect declines worldwide, this study also serves as a warning of yet another key ecosystem service that will certainly be lost unless a major agricultural transformation to organic systems is mobilized. Dung beetles, whose actions in soils not only protect against pathogens, but also unlock critical nutrients, are in decline. The impacts of dung beetles on soil fertility are vital to the sustainability of farms and pastures used to maintain livestock. By burying and processing feces on cattle farms, dung beetles introduce 80% more nitrogen into the soil than would otherwise remain. By increasing soil organic matter, dung beetles simultaneously increase water infiltration, thus stabilizing farms and heavily grazed areas against erosion, flooding, and drought.

Findings from the present study highlight the need for dung beetle diversity in addition to abundance, since some dung beetles bury feces more effectively than others. Notably, researchers find that the commonly introduced species O. nuchicornis, which tends to dominate over other species and reduce overall diversity, is less effective at burying feces, with consequences for both E. coli contamination and soil fertility. Similarly, previous work attests to the importance of soil microbial diversity for maintaining ecosystem services. The key to healthy produce and fertile soils, across the board, is diversity.

Due to agrochemical use, that precious diversity is in decline. Monitoring in Europe, according to the 2019 review of insect declines, shows the greatest terrestrial loss of insect biodiversity on record to date: more than 60% of documented dung beetle species are in decline. Soil microbial diversity, too, is threatened by continued application of pesticides in industrialized agriculture. Highly toxic gases known as “soil fumigants” are used on a wide range of high-value crops to control nematodes, fungi, bacteria, insects, and weeds. Soil fumigants wipe out entire soil communities, thus necessitating the use of other chemicals  to provide the fertility and pest control services that soil  organisms provide. In addition to fumigating soil, which intentionally kills all  living things in the soil, other chemical-intensive practices also threaten soil  life. Glyphosate, the most widely used herbicide, is also an antibiotic. Glyphosate-tolerant plants release glyphosate into the soil, where it has a continued impact on soil microbial diversity.

Beyond Pesticides holds the position that these patterns carry a lesson. Insects and microbes that act to control crop pests and fertilize the soil reduce the need for pesticide and chemical fertilizer use. Reliance on chemical controls creates a vicious treadmill: pesticide use kills natural agents of pest control, thus creating a demand for more pesticide use, which kills more of the beneficial organisms, and so on.

Join Beyond Pesticides in getting off the toxic treadmill and instead working to build a sustainable food system based on natural control systems. Be a model for your community by creating a pesticide-free zone in your home yard, neighborhood, or even jurisdiction. Add your pesticide free zone to the map by taking our Pesticide Free Zones Survey. Show your neighbors and beyond that a world free of pesticides is both desirable and achievable.

(Beyond Pesticides, April 17, 2019)  A neurotoxic pesticide labeled “bee-safe” has been found to be harmful to bees, according to a new study. Flupyradifurone (FPF), the subject of the study, is a novel chemical that was hastily registered in the wake of public awareness about the impact of neonicotinoid insecticides on bees. A systemic insecticide and a nicotinic acetylcholine receptor (nAChR) agonist, it functions in the same way as a neonicotinoid, though it is in the butanolide family. “Lethal and sublethal synergistic effects of a new systemic pesticide, flupyradifurone (Sivanto®), on honeybees,” not only debunks the myth that FPF is safe on its own, it also delves into the FPF’s synergistic effects with a commonly used fungicide propiconazole (PRO). PRO, on its own, has no impact on bee mortality. A rarely studied realm of pesticides, the study defines a synergistic effect as, “when combined exposure to two factors results in an effect that is significantly greater than the sum of individual effects.”

Researchers manipulated six healthy honey bee (Apis mellifera ligutica) colonies and observed the impact of varying amounts of pesticide exposure, including both individual and synergistic effects, on behavior and mortality. They recorded data over seasons and between worker types.

A field-realistic dose of FPF caused a 73% mortality in bees when combined with the fungicide PRO. The synergy of the two pesticides increased abnormal behaviors (motor coordination deficits, hyperactivity, apathy, curved-down abdomen, moribund). The pesticides were more toxic to foragers than in-hive bees and were more toxic in the summer versus the early spring.

Toxicity results for FPF in this study were higher than those reported by the Environmental Protection Agency (EPA), likely due to a difference in protocol. EPA’s risk assessment does not require a thorough assessment of abnormal behaviors and measure behavioral changes up to four hours after treatment – when the effects have often already worn off. These researchers looked closely at the honey bee behaviors one hour after exposure, when abnormal behaviors are more likely to be exhibited.

Lead author Simone Tosi, PhD told Newsweek, “This work is a step forward toward a better understanding of the risks that pesticides could pose to bees and the environment. We provide the first demonstration that the combination of two pesticides can synergistically increase the frequency of pollinators with abnormal behaviors, and suggest methodologies that could be implemented for assessing the risks caused by pesticides.”

The impact of combinations of chemicals is potentially enormous and often overlooked. As mentioned in Beyond Pesticides’ Action of the Week on mixtures, “When pesticides are sprayed on our crops, lawns, and roadsides, and enter into our waterways, groundwater and drinking water, we are exposed to whole formulations, whole tank mixtures, and whole pesticide combinations, not just active ingredients (those that the manufacturer claims are the only ingredients that attack the target pest).” While not well understood and poorly regulated, a few studies have been done that show negative impacts of synergistic effects.

For example, Warren Porter, PhD., professor emeritus of zoology and environmental toxicology at the University of Wisconsin, Madison, examined the effect of fetal exposures to  a mixture of 2,4-D, mecoprop, and dicamba exposure. These chemicals, frequently combined in lawn products, had a strikingly deleterious impact on mice reproduction.

Similarly, Tyrone Hayes, PhD, found reproductive effects on frogs when they were exposed to mixtures of chemicals. “…only atrazine causes the hermaphroditism, but when atrazine has all of its little friends along, you are exposed to atrazine longer. So the combination of chemicals is not synergistic in a way that it is causing more hermaphroditism, but they are delaying development so that the atrazine exposure is longer and increasing the effects.”

Beyond Pesticides has been on the case of flupyradifurone since its registration in 2015. As the public becomes aware of the harm that particular classes of insecticides have on pollinators – not to mention entire ecosystems and/or human health – new chemicals with different nomenclature but similar effects will always pop up in their place. Beyond Pesticides therefore advocates for a paradigm shift from “whack-a-mole” pesticide bans to organic policy that precludes toxic chemicals entirely. An organic approach alleviates the need to analyze just how destructive synergistic effects are.

(Beyond Pesticides, April 16, 2019) Help stop another attack on local authority in Maine – a bellwether state that has upheld local pesticide restrictions and leads the nation. Maine has led the nation in supporting the local democratic process as communities across the state have adopted pesticide use standards on public and private property that are more restrictive than state laws.

This will be the third attack on local authority in recent years – each time beaten back with public opposition. This time preemption language has been introduced as a clause in the innocuous sounding bill LD 1518, An Act to Establish a Fund for Portions of the Operations and Outreach Activities of the University of Maine Cooperative Extension Diagnostic and Research Laboratory and To Increase Statewide Enforcement of Pesticide Use. The language was introduced by Rep. Stephen Stanley (D), who ran unopposed in the 2018 Democratic primary.

The bill’s language establishes barriers to local decision making, giving sole authority to the state to determine the acceptability of local pesticide restrictions.  As drafted, the bill would force municipalities to submit a request to ban a substance to a statewide board, which would make the decision as to whether the community could block the chemicals.

• 1471-CC. Elimination of use of pesticide in political subdivision
  A political subdivision of the State that wants to eliminate use in the political subdivision of a pesticide registered by the United States Environmental Protection Agency shall submit a request to eliminate use of the pesticide to the board. The board shall determine whether the pesticide should be further regulated based upon the board’s expertise in toxicology and available scientific information relating to the adverse environmental, health and other effects of the pesticide under Title 7, section 610, 26 subsection 1. The board’s review must include participation of the officers of the political subdivision and board staff and may include experts and other interested parties as the board determines appropriate.

The language in the bill represents a dramatic change in the state of Maine. Local authority allows communities the authority to represent the concerns of local residents, consider the science and need for pesticides, and affirm the importance of local jurisdictions considering local environmental conditions. A recent study, Anti-community state pesticide preemption laws prevent local governments from protecting people from harm, finds that state pesticide preemption laws “compromise public health and economic well-being” by preventing localities from enacting pesticide use restrictions on private property that are more restrictive than their state’s regulations. In the words of the authors, “By eliminating the ability of local governments to enact ordinances to safeguard inhabitants from health risks posed by pesticides, state preemption laws denigrate public health protections.” The study, published in the International Journal of Agricultural Sustainability, reviews scientific and historical evidence of the failure of state and federal pesticide laws to protect localities from pesticide poisoning, and highlights the inability of localities to compensate for that failure under present laws. Communities seeking to protect their residents typically issue community-wide restrictions to ensure protection of shared community resources, including air, land, and waterways, from pesticide drift, runoff, and other nontarget effects —as is the case with other community decisions on recycling, smoking, and zoning. The study’s authors document how industry influence led to the adoption of state laws that undermine the ability of localities to enact protective pesticide standards they determine are necessary to protect public health and the environment.

Letter to Maine Governor and State Legislature from Maine Residents: Use this link to message Governor Janet T. Mills and the Maine Committee on Agriculture, Conservation, and Forestry.

I urge you to reject §1471-CC. Elimination of use of pesticide in political subdivision, of LD 1518. The right of local governments throughout Maine represents an important public health and environmental protection authority. Although the chemical industry had argued for over a decade in the 1980s that the nation’s federal pesticide law prohibits local regulation of pesticides, the U.S. Supreme Court affirmed the rights of cities and towns to regulate pesticides under federal law. The court found on June 21, 1991 that FIFRA “leaves the allocation of regulatory authority to the ‘absolute discretion’ of the states themselves, including the option of leaving local regulation of pesticides in the hands of local authorities.” Maine chose to uphold local authority.

Thank you.

Letter to the Maine State Legislature from Non-residents: Tell the Maine Committee on Agriculture, Conservation, and Forestry that you care about this attack on public health and the environment.

I am concerned about any attack on democratic values and the rights of local communities across the United States to protect themselves and the environment from the use of toxic pesticides. Because of this, I am writing you to oppose LD 1518, “An Act to Establish a Fund for Portions of the Operations and Outreach Activities of the University of Maine Cooperative Extension Diagnostic and Research Laboratory and To Increase Statewide Enforcement of Pesticide Use.”

As residents of the U.S., people travel, visit as tourists, and have family in all parts of the country. Because of the growing concern about the local impacts of pesticides, local governments play an important role in protecting public health and the environment. That is why I’m so concerned about this legislation, just introduced in the Maine legislature, that would take away the right of communities to restrict toxic pesticides. I am urging you to actively oppose this legislation and do everything in your power to protect the rights exercised by the local democratic process.

(Beyond Pesticides, April 15, 2019) Beyond Pesticides’ 37th National Forum, Organic Strategies for Community Environmental Health: Eliminating pesticides where we live, work, learn, and play, co-convened with the Children’s Environmental Health Center of the Icahn School of Medicine at Mount Sinai, brought together scientists, land and park managers, urban farmers, policy makers, and advocates to chart a course that takes on the big public health and environmental issues associated with chemical-intensive practices.

The conference began with a tour of the organically managed Battery Park Conservancy (in lower Manhattan) and the urban farm at Wagner Houses (East Harlem) of the New York City Housing Authority and coordinated by Green City Force. The Forum brought together speakers who addressed the problems associated with pesticides use, cutting edge science, and solutions embodied in organic practices.

The speaker line-up brought together leaders in their fields. Joan Dye Gussow, EdD, a leader of the organic and local food movement, kicked off the conference with a talk grounded in a history of pesticide contamination and poisoning issues that helped to launch mainstream organic agriculture, now subject to attacks that are undermining public trust in the standards and the organic label. Dr. Gussow was awarded Beyond Pesticides’ Dragonfly Award, for her “tireless educating and advocating for a society that values a healthy food system and functions in harmony with nature.” Participants heard talks from those meeting the challenges necessary to transform the public’s understanding of: the serious adverse effects of pesticides, including talks on the endocrine disrupting, cancer, and debilitating gut microbiome effects of glyphosate (Roundup); the link between autism and pesticides; approaches to living with spontaneous vegetation in urban areas with a focus on urban ecology; biodiversity and pollinator protection; organic turf and landscape management; urban farming led by New York City youth; pesticides and the law; genetic engineering and the challenges to health and the environment; and many other topics.

The Forum featured the New York City premiere of the film Ground War. The film is a moving depiction of a son’s quest for answers about his father’s cancer-which takes him into the world of doctors, scientists, pesticide regulators, victims of pesticide poisoning, activists, and land managers. The film screening was followed by a panel discussion that featured former applicator of Roundup, groundskeeper Dewayne “Lee” Johnson—terminally ill from non Hodgkin lymphoma, but committed to speaking out. Mr. Johnson won a $289 million jury verdict against Monsanto (Bayer) last year. The Forum sessions will be available on video in the near future.

[The following coverage of Organic Strategies for Community Environmental Health: Eliminating pesticides where we live, work, learn, and play, the 37th National Pesticide Forum, is reprinted with permission by Organic Insider, a weekly newsletter about the organic food industry.]

(April 10, 2019) At [the] 37th National Pesticide Forum  [April 5-6, 2019] in NYC, doctors presented the latest research on how harmful glyphosate is to the body, lawyers and researchers discussed key matters related to chemicals, and landscapers talked about effective management practices for nurturing soil and plant health.

Yet, what may have been the most compelling and inspirational presentations were those by activists from across the U.S. — from Hawaii to Massachusetts and from Colorado to Maryland — who have worked to ban pesticides in their local cities and states. These people realized that because our federal government has put the interests of major chemical companies ahead of human health, there was no choice but to take matters into their own hands.

“The aggressive undermining of the laws by the EPA has been an important motivator around the country for citizens to use local authority to protect themselves and their families. Each group comes at it from a different perspective, whether it is a food safety one or because they are concerned about pesticide use on parks and playgrounds. Yet, they all understand that these chemicals are very dangerous. When these folks work with us, they are looking for solutions — ones that work and are effective,” said Jay Feldman, Executive Director of Beyond Pesticides, the organization which hosted and organized the conference.

What may not be readily apparent, however, is the critical role that organic standards play in the banning of these chemicals.

“In the case of Portland, Maine and Montgomery County, Maryland, we relied on and presented standards in the Organic Foods Production Act of 1990 (OFPA) that are relative to turf and landscape management. It is the only standard in federal law that embraces the precautionary principle and is one that is protective of human health and the ecosystem. Because of OFPA and organic standards, we are able to demonstrate to local municipalities that there is another way, and the fact that these alternatives carry the imprimatur of the federal government is of tremendous consequence,” put forth Jay Feldman.

Given its importance, any degradation of these organic standards translates into weaker tools to fight pesticides on a local level. One such example of this was the illegal changing of “The Sunset Rule.”

At the National Organic Standards Board (NOSB), the 15-member advisory board that makes recommendations to the USDA about processes and ingredients, any specially approved material is allowed for a five-year period. This gives a farmer or a company time to come up with an alternative or allows the NOSB a period to evaluate new science.

As it was originally designed, at the end of the five-year period, that specially approved material “sunsets off” or expires, with a 2/3rds vote of the board needed to extend it for another five years.

In September of 2013, the USDA abruptly and unilaterally changed The Sunset Rule without any public input and made it such that a 2/3rds vote of the board is now required to remove an ingredient.

Given the prevailing attitude of many NOSB members who want to have “more tools in the toolbox”, removing a synthetic ingredient from the National List has since been incredibly difficult, if not impossible. (This change to The Sunset Rule led to Alexis Baden-Mayer of the Organic Consumers Association getting handcuffed by police and is the subject of a lawsuit against the USDA by the Center for Food Safety and 13 other organic groups.)

As such, having strong organic standards transcends the desire to have a high-integrity, high-quality organic food system. It means something larger.

“These local groups are demonstrating that we can eliminate exposure to chemicals that are hazardous to our health, and we are developing an approach to address the climate crisis and the insect apocalypse, both of which are foundational to life,” said Jay Feldman.

Without question, the highlight of the National Pesticide Forum took place on Saturday night at the showing of the excellent documentary Ground War (a filmmaker’s investigation into the death of his father takes him deep into the world of golf, chemical lobbying, and citizen activism, where he learns that the rampant use of pesticides around the world may be far more damaging than he thought.)

At the movie premiere was Dewayne “Lee” Johnson, the California groundskeeper who sued Monsanto for giving him Non-Hodgkin’s lymphoma and was subsequently awarded $289M.

Mr. Johnson made the trip to NYC from California despite the fact that cancer has taken a serious toll on his body, and he is covered in lesions. Needless to say, this man is an unquestioned hero to all of us in the organic community.

Overall, Beyond Pesticides put on an excellent conference and demonstrated what an important organization it is to our movement.

(Beyond Pesticides, April 12, 2019) The Center for Biological Diversity (CBD) announced on April 3 that it is suing the U.S. Fish and Wildlife Service (FWS) for its failure to release public records, despite multiple FOIA (Freedom of Information Act) requests, that would reveal on-the-ground impacts of FWS allowing use of neonicotinoids and genetically engineered (GE) crops in wildlife refuges. Last August, in yet another rollback of protections for wildlife, the environment, and public health, the Trump administration reversed a 2014 FWS decision to ban the use of neonicotinoids and GE crops in National Wildlife Refuges. If successful, the CBE lawsuit, filed in U.S. District Court for the District of Columbia, would compel the agency to provide the requested documents. This would allow the public, largely through the work of NGO (non-governmental organization) watchdogs, such as CBD and Beyond Pesticides, to understand what harms are being caused on the nation’s protected public lands by the administration’s reversal of the 2014 ban.

Hannah Connor, a CBD senior attorney, said, “The goal of the lawsuit is to get them to comply with the Freedom of Information Act and produce the records that have been requested. . . . We aren’t asking them to go above and beyond. We’re just asking them to comply with the law and bring some transparency to this process.” She also commented, “Pesticide-intensive farming has no place on America’s national wildlife refuges. The public has a right to know where and when these dangerous practices are being allowed to poison our refuges. These incredibly precious places were set up to protect wildlife, not industrial-scale commercial agriculture.”

Ms. Connor also noted, in The New Food Economy’s coverage of the matter, that CBD has encountered delays in getting documents via FOIA requests with past administrations, but has never faced a delay as protracted as this one with FWS. It is noteworthy and likely relevant that in December 2018, the Department of the Interior, under whose auspices FWS operates, submitted to the Federal Register proposed rule changes that could limit the number of FOIA requests an individual could submit, lengthen the turnaround for FOIA requests, and establish a level of “burden” that requesters should not exceed. This was done during a government shutdown without any public announcement or press release by the agency.

In 2014, advocates welcomed the announcement, by FWS, that it would ban neonicotinoid insecticides from all wildlife refuges nationwide by January 2016, as well as phase out the use of GE crops. The decision followed years of lawsuits and an intensive advocacy campaign by CFS, Public Employees for Environmental Responsibility (PEER), and Beyond Pesticides. It was a hopeful sign, in that FWS was the first federal agency to restrict the use of neonicotinoids based on the principle of precaution. At the time, Beyond Pesticides Executive Director Jay Feldman commented, “The FWS decision represents an important and responsible departure from EPA’s decision to allow the widespread use of neonicotinoids despite the non-target effects to managed and wild bees and other beneficial organisms.”

Then came the 2018 FWS announcement of the reversal, in which FWS said that genetically modified seeds, used together with neonicotinoids, “[maximize] crop production” — pointing to the friendliness the Trump administration exhibits toward industry, in this case, the agrochemical sector, and to its relative indifference to environmental, public, and wildlife health. Very soon after that announcement, CBD and the Center for Food Safety (CFS) sued the administration over the reversal, citing the FWS’s failure to consider the risks of increased pesticide use for threatened species that rely, for food, habitat, and protection, on national wildlife refuges. Earlier in 2018, CBD released a report, No Refuge, that documented the intensive use of pesticides on lands designated as refuges for wildlife and protected under U.S. law.

That use amounted, in 2016 alone, to 490,000 pounds of pesticides sprayed on crops grown in national wildlife refuges. As of that year, the refuge systems that endured the heaviest use of pesticides were the Klamath Basin National Wildlife Refuge Complex, the Central Arkansas Refuge Complex, the West Tennessee Refuge Complex, the Tennessee National Wildlife Refuge Complex, and the Chesapeake Marshlands National Wildlife Refuge Complex. Intensive commercial farming — and use of pesticides — have spiked with the advent of GE crops, such as corn and soybeans. Increased pesticide use threatens the long-term health of these sensitive habitats and the wildlife that depend on them.

Beyond Pesticides wrote, back in 2012: “Farming has long been used on national wildlife refuges for multiple purposes like habitat restoration, which involves destroying invasive species to make room for native plants. However, in recent years, refuge farming has been converted to GE crops because the agency claims GE seed is the only seed farmers can obtain today. These GE crops are mostly engineered for a single purpose: to be resistant to herbicides, mainly Monsanto’s ubiquitous Roundup. Because the crops are tolerant to herbicides, their plantings lead to more frequent applications and increased amounts of toxic herbicides. This overreliance on herbicides used in GE cropping systems has fostered an epidemic of herbicide-resistant ‘superweeds’ in the past decade as weeds have mutated.”

The 2014 ban would have protected wildlife broadly, as well as honeybees, bumblebees, and other pollinators, from the impacts of neonicotinoids, which are primarily implicated in the devastation of pollinator populations, as well as the federally threatened and endangered pollinators that live in National Wildlife Refuges. These compounds are also contributing to the dramatic drops in overall insect abundance, which some scientists label as a coming “insect apocalypse.” Research has identified astonishing reductions in insect “biomass,” including that there were, in the 1970s, 60 times as many insects in some locations as there are currently, and that more than 75% of the insect decline occurred from 1990–2017. As Beyond Pesticides has noted, “pesticide use in these sensitive areas poses risks to pollinators, aquatic organisms, migratory birds, and other wildlife on refuges that were created to protect them.”

(Beyond Pesticides, April 11, 2019) A recent study of 29 discrete, small European waterways found ubiquitous pesticide contamination. Analyzed samples contained a total of 103 different pesticides and 21 veterinary drugs. These data add to the growing body of evidence that there is a significant, ongoing threat to the aquatic environment as a result of chemical-intensive farming practices.

Researchers took a “snapshot” of samples from streams, rivers, and canals in ten different countries: Austria, Belgium, Denmark, France, Germany, Italy, The Netherlands, Poland, Spain, and the United Kingdom. Sample sites were chosen in rural areas with arable land. The water samples were screened for a wide range of pesticides and veterinary drugs using liquid chromatography. The study was published in the journal Science of the Total Environment.

Pesticides find their way into water systems via dry deposition (absorption of particles from the atmosphere), pesticide drift, and runoff from contaminated soils. Of the total 103 detected pesticides, 45% were herbicides. Terbuthylazine, a broadleaf herbicide in the chemical class triazine (the same class that contains the U.S.-utilized atrazine), was found in all samples.

There were 24 unapproved pesticides in the water samples. Rather than illegal current use, it is more likely that these are leftover pesticides from former, legal applications and are only now leaching into the waterways. This is a disconcerting example of the living history and persistence of synthetic chemicals – they do not disappear after use.

The study addresses the complex issue of risk assessment, running into variable regulatory standards and the failure to assess the impact of chemical mixtures. Combinations of chemicals and metabolites (breakdown compounds) may have a greater biological impact than a single compound, but it is poorly studied and under regulated. Regardless, singular compounds raise issues in and of themselves. The researchers utilized regulatory acceptable concentrations (RACs) published by the Federal Environmental Agency of Germany (UBA). Fifteen individual pesticide risk quotients exceeded RACs. For example, one water sample had levels of 2,4-D 8.8 times higher than the RAC.

Most of the veterinary drugs in the samples were antimicrobials, and the majority of those were antibiotics. The antibiotic dicloxacilin was present in ~66% of the analyzed samples. Veterinary antibiotics are poorly absorbed by animals; between 30-90% of the parent compound is excreted. Waterways become contaminated with veterinary drugs both directly from the land where the animals are excreting and also from fields fertilized by manure.

Antibiotics are highly stable compounds with low environmental degradation rates. Metabolites, breakdowns of the original chemical, can transform back into the parent compound after excretion. While the concentrations of antibiotics are relatively low in the environment, their widespread and consistent use across industries has raised the issue of antibiotic resistance in public health.

Paul Johnston, one of the study’s authors, told The Guardian, “Farmers don’t want to pollute rivers, and water companies don’t want to have to remove all that pollution, so we have to work to reduce reliance on pesticides and veterinary drugs through more sustainable agriculture. This is not a case of us versus farmers or water companies.”

Concurrent with the onslaught of negative news related to pesticide use is an emergent understanding that farmers can sustain yields and profit margins with reduced inputs.

(Beyond Pesticides, April 10, 2019) Last month, the Washington State Senate unanimously passed HB 1906, designating April 10 as Dolores Huerta Day. In July of 2018, a similar California law proclaimed April 10 Dolores Huerta Day in that state. In an interview with Vida del Valle, Ms. Huerta stated, “I’m happy to hear that our young learners will have the opportunity to learn more about social justice and civil rights, because there is still a lot of work to do by the Dolores Huerta Foundation.”

Following decades of leadership in the fight for farmworker justice, Ms. Huerta founded the Dolores Huerta Foundation in 2002, with a focus on grassroots organizing in Central Valley. According to its website, the Dolores Huerta Foundation trains low-income Central Valley residents “to advocate for parks, adequate public transportation, infrastructure improvements, the reduction of pesticide use, increased recreational opportunities, and culturally relevant services.”

“We build leadership in low-income communities and organize people so that they can have a sense of their own voices and their own power,” Ms. Huerta said of her foundation in an interview with Civil Eats. “Once they understand this process and they have the power to change policy – and politicians – they really feel empowered and they want to go on and keep organizing,” she explained, adding, “It’s wonderful. I call it ‘magic dust.’”

Dolores Huerta has been spreading this “magic dust” for over six decades.

Ms. Huerta co-founded the National Farmworkers Association – now called the United Farm Workers (UFW) – in 1962. Ms.Huerta became well known as a thought leader, organizer, lobbyist, and negotiator. As lead organizer for the historic Delano grape boycott of 1965, she convinced more than 17 million consumers to stop buying grapes in support of workers’ demands for collective bargaining rights. The boycott was as much a battle against growers as it was against the U.S. government, which interfered by purchasing grapes to send to U.S. soldiers in Vietnam. Nonetheless, the campaign succeeded, and Ms. Huerta led the negotiations that followed to secure collective bargaining agreements between the California grape industry and UFW.

Author and organizer Randy Shaw credits Ms. Huerta and her collaborators in the fight for farmworker justice for helping to lay the groundwork for “the whole idea of Environmental Justice.” “The Environmental Justice movement said that certain environmental hazards are disproportionately impacting on people of color,” Mr. Shaw explained in the 2017 documentary, Dolores. He continued, “It wasn’t simply stopping DDT, but it was also making the larger point, you’re only allowing this because of who the workers are, and their race and class background.”

That larger point came with a larger cost. “Once we started making those kind of demands, we had the same response that the Black movements had,” said Ms. Huerta of the fight for farmworker rights. “Our people were killed.” Ms. Huerta herself was brutally attacked by a crowd control police officer during a demonstration in San Francisco in 1988. She broke three ribs and had to have her spleen removed. Ms. Huerta said, “The system doesn’t really want brown people or black people to have an organization and to have real power. I found out that no matter what I did, I could never be an American. Never.”

The fight for pesticide regulation is inextricably linked to the fight for immigrant rights. “Growers don’t want [their workers] to be legalized,” said Ms. Huerta in Dolores. “Because once they’re legalized, they can protest against pesticide poisoning, they can protest against the low wages they’re being given,” she said.

To this day, Ms. Huerta is fighting for stricter regulation and a transition away from pesticide use. As stated on its website, the Dolores Huerta Foundation “organizes communities that face critical exposure to pesticides through their work in the fields and the proximity of their residence to them. . . DHF advocates against the use of harmful pesticides whenever possible.”

As Ms. Huerta points out in an interview with NPR, women and children working in the fields are especially vulnerable to pesticide poisoning: “The pesticides in the fields really affect women even more than they do men. They affect children and they affect women more than they do men.” Research indicates that exposure to common agricultural pesticides, both during development and in adulthood, is associated with increased susceptibility to breast cancer. Across the board, studies show that children’s developing organs create “early windows of great vulnerability” during which exposure to pesticides can cause lifelong damage.

Ms. Huerta represents one of many women who have been standing up for the right to healthy and safe working conditions. “There were more women involved in the UFW than probably every other labor union in the United States combined,” said author and organizer Randy Shaw in Dolores. However, many believe that Ms. Huerta was not given the credit she deserved for her accomplishments. Ms. Huerta was the only woman on the executive board during her tenure in the UFW, and several of those closest to her lament that fellow board members resisted her leadership expressly because of her gender. When co-founder Cesar Chavez died in 1993, the board chose not to elect Huerta as the new president due, many believe, to their reluctance to appoint a female leader. In August, the UFW executive board appointed union Secretary-Treasurer Teresa Romero to replace UFW’s retiring president Arturo S. Rodriguez. She is the first Latina and immigrant president of a U.S. national union.

“We’re knee deep in sexism when it comes to why she isn’t studied, and why people don’t know her,” said educator and activist Curtis Acosta, featured in the 2017 documentary. According to Mr. Acosta, Ms. Huerta publicly criticized the UFW itself for being “rife with sexism.” According to Mr. Acosta, Ms. Huerta said, “I even said to Cesar at one point in time, I said, look, we have a lot of machismo here in the farmworkers movement, and I am not going to take it anymore.” Her message to the young women and Chicana girls with whom she now works – be bold and take credit for your work.

As some of Ms. Huerta’s colleagues note, her erasure from history is not only the product of sexism, but also a testament to her continued threat to those in power. In 2010, the Texas State Board of Education removed Dolores Huerta from the state’s history curriculum. In that same year, fueled in part by Ms. Huerta’s controversial messaging to students at a Tucson school, the Arizona House Education Committee passed a bill to ban Ethnic Studies in the state. Addressing the committee at the bill’s hearing, then Superintendent Tom Horne characterized Ms. Huerta as “a former girlfriend of Cesar Chavez.” With the passage of the ban, Mr. Horne and the Education Committee struck deeper than insult – the law effectively targeted and removed a longstanding Mexican-American studies program that had empowered Tucson’s Chicano students to hold pride in their ancestry and stand up for their rights.

Though the newly designated Dolores Huerta Day will not be recognized as a legal holiday in either Washington or California, its passage provides an opportunity for education and critical reflection. The day offers an opportunity to recognize and support the work of Dolores Huerta and join with advocates standing up for justice in their communities.

As part of the 37^th annual National Pesticide Forum this past weekend, Beyond Pesticides featured a panel of youth advocates for environmental justice. Stay abreast of updates on our Youtube page to learn directly from advocates how you can be a part of the movement to grow out of our oppressive present and into an ecologically and socially just future of food production.

(Beyond Pesticides, April 9, 2019) It is time for all local and state governments and school districts to stop the use of glyphosate/Roundup. The last month has seen a level of activity that supports immediate action. A second jury came in with the verdict that the herbicide caused plaintiffs’ non-Hodgkin’s lymphoma (NHL) —this time handing the manufacturer, Monsanto/Bayer, a bill for $80 million ($5 million in compensatory damages and $75 million in punitive damages).

Tell your Governor to act now to stop the use of glyphosate/Roundup.

 Insurance companies are now backing away from Roundup. Harrell’s is a company that sells chemical pesticides, synthetic fertilizers, and “adjuvants and colorants,” among other products, primarily to golf courses, and to the horticulture-nursery, turf, and landscape sectors. The company announced on March 11 that it stopped selling products containing glyphosate as of March 1, 2019 because neither its current insurance company nor others the company consulted would underwrite coverage for the company for any glyphosate-related claims.

Harrell’s CEO stated: “During our annual insurance renewal last month, we were surprised to learn that our insurance company was no longer willing to provide coverage for claims related to glyphosate due to the recent high-profile lawsuit and the many thousands of lawsuits since. We sought coverage from other companies but could not buy adequate coverage for the risk we would be incurring. So we had no choice other than to notify our Harrell’s Team and customers that we would no longer offer products containing glyphosate.”

The announcement stands in contrast to a Fox Business story shortly after the verdict in the Johnson v. Monsanto case. That article reported, “Top U.S. retailers such as Home Depot, Target, Walmart and Amazon are sticking by Monsanto’s controversial weedkiller Roundup one week after a California jury awarded a school groundskeeper $289 million for proving the spray caused him to develop non-Hodgkin’s lymphoma.” Indeed, insurer (and perhaps re-insurer) concern may well increase in light of the deluge of lawsuits glyphosate use has triggered.

Meanwhile scientific studies linking glyphosate to serious adverse effects still keep coming in. A recent study by Fabiana Manservisi, Corina Lesseur, et al., published in Environmental Health on March 12, shows glyphosate-based herbicides are associated with endocrine and reproductive effects. This is on top of the scientific findings by the World Health Organization that the chemical probably causes cancer. A meta-study in February 2018 concluded that there is a “compelling link between exposures to GBH [glyphosate-based herbicides] and increased risk of NHL.” Still the U.S. Environmental Protection Agency fails to act.

On March 1, the City of Miami established a ban, which went into immediate effect, on the use of any glyphosate-based herbicides (including Roundup compounds) by the city and any of its contractors.

It is time to stop glyphosate use or risk continued exposure to the state’s populations and adverse health effects, along with the financial exposure that the threat of litigation brings.

Beyond Pesticides and other organizations that have worked for many years to educate stakeholders and policy makers about the dangers of pesticides, stand ready to assist the state and communities in transforming pest management by eliminating a reliance on toxic pesticides and adopting organic management practices.

Thank you for your attention to this important matter.

(Beyond Pesticides, April 8, 2019) Officials in Europe and the U.S. focus on banning problem pesticides, raising concerns about their replacements in the face of pesticide-intensive management strategies, while organic advocates call for a systems change in land management. In reference to widespread community bans of Roundup/glyphosate, Cary Gillam, author of Whitewash, told last year’s Beyond Pesticides’ Forum, “Glyphosate is the poster child for the bigger pesticide problem.” She continues, “If it goes away tomorrow, we are not okay.” Because of this, Beyond Pesticides has strategically sought to transform our country’s approach to pest management, both agricultural and residential/structural, by eliminating a reliance on pesticides and advancing organic management practices that do not rely on toxic inputs. This Daily News Blog post offers updates on progress in the European Union (EU), in the U.S. Congress, and in communities and sates nationwide.

The EU is poised to ban clorothalanil, a commonly used — and highly toxic — organochlorine fungicide, The Guardian reported, in mid-to-late May 2019. After a review by the European Food Safety Authority (EFSA), EU states voted to approve a ban. EFSA identified as a chief safety concern the possibility that breakdown products (metabolites) of the compound may cause damage to DNA. The group also reported that for all identified uses, there is “a high risk to amphibians.” It further noted that recent research points to chlorothalonil (and other fungicides) as primary contributors to the alarming decline in bumblebee populations. The ban comes shortly after the European Parliament’s Special Committee (the PEST Committee) approval of a draft report recommending significant strengthening of pesticide restrictions.

Chlorothalonil, sold commercially under the names Bravo, Echo, and Daconil, is a broad- spectrum, non-systemic fungicide used to control fungal foliar diseases of vegetable, field, and ornamental crops; it is also deployed as a wood protectant, anti-mold and antimildew agent, bactericide, microbiocide, algaecide, insecticide, and acaricide. Its impacts on bumblebee and other bee populations have been chronicled by Beyond Pesticides and others; the mechanism of action is strongly suspected to involve disruption of the organisms’ gut biomes. The chemical is also regarded as a likely human carcinogen.

The United Kingdom’s National Farmers Union reacted to this EU move by calling it “overly precautionary,” and warning that such a ban fails “to consider the particular importance of this [pesticide] in the control of critical fungal diseases and in managing disease resistance. As a result, we believe sectors of UK agricultural and horticultural production will be put at significant risk.”

However, Mark Shardlow, director of the nonprofit Buglife, supported the ban, saying that the fact that established links to bumblebee harm had not led to safety tests for wild bees showed the inadequacy of the EU’s regulatory system. He added, “[T]he EU process failed to apply the EFSA guidance on assessing risk to bees, so there were no bumblebee safety tests. When will regulators learn the lessons, [and] stop kowtowing to the demands of the pesticide manufacturers?”

A spokeswoman for the European Commission (EC), the executive branch of the EU, defended the action, saying, “The [chlorothalonil ban] is based on EFSA’s scientific assessment, which concluded that the approval criteria do not seem to be satisfied for a wide range of reasons. Great concerns are raised in relation to contamination of groundwater by metabolites of the substance.”

Back across the pond, in the ongoing “chlorpyrifos saga,” Senator Tom Udall of New Mexico introduced a bill in the U.S. Senate on March 28, just one day after the current Environmental Protection Agency (EPA) once again argued to delay the agency’s own 2016 ban on the compound, to ban the use of the toxic pesticide, chlorpyrifos. If passed and enacted, the Protect Children, Families and Farmworkers from Nerve Agent Pesticides Act of 2019 (S.921) would ban the compound, widely recognized as a dangerous neurotoxin that imperils human health, and puts children and farmworkers at particular risk. Chlorpyrifos has impacts beyond its neurotoxicity; it is also associated with harmful effects on human endocrine, reproductive, hepatic, and renal function, is a skin and eye irritant, and distorts development. Cosponsors of the Senate bill include Senators Blumenthal, Booker, Cardin, Feinstein, Gillibrand, Harris, Leahy, Markey, Merkley, Sanders, Van Hollen, and Whitehouse.

The chlorpyrifos saga began as far back as 2000, with an agreement between EPA and Dow AgroSciences, maker of the pesticide, to stop the sale of the chemical for most home, lawn, and garden uses because of its health risks to children, which proscription did happen. Fast forward to 2015, when EPA proposed to eliminate all food tolerances for the compound — functionally, a ban — although other non-food uses, for landscape and turf management (especially golf courses), and for greenhouse and mosquito control were not affected by the decision. This proposal was made public on the very day that a U.S. Court of Appeals judge in the Ninth Circuit ordered the agency to respond, finally, to a suit filed nine years earlier petitioning for a ban on all uses of chlorpyrifos, given the established health risks of exposure. EPA dithered, ultimately promising to release a final rule in December 2016.

In 2016, the agency did develop a regulation banning the compound. Then, in March 2017, Trump EPA Administrator Scott Pruitt, just three weeks after meeting “privately” with the CEO of Dow chemical, rejected the conclusions of EPA’s own scientists and announced that EPA would reverse course and not ban the use of chlorpyrifos on food crops. Last August, the Ninth Circuit Court once again weighed in, ordering EPA to implement its previous proposed ban of the chemical in the U.S.

Andrew Wheeler, the EPA Administrator who followed Mr. Pruitt, soon after asked the court to rehear the chlorpyrifos case in an en banc proceeding — one in which a case is heard before all the judges of a court rather than by a selected panel of them. (The request is based primarily on challenges to that court’s authority in the matter.) In February 2019, the court granted the request, meaning that public health, labor, and science advocates will have to re-argue, again, that chlorpyrifos should be banned from all food uses. In the wake of this protracted delay, legislators such as Senator Udall have begun to pick up the mantle, given EPA’s failure to protect the public from this toxic and dangerous compound.

Over on the U.S. House side, Representative Nydia Velázquez of New York filed a bill in January, the Ban Toxic Pesticides Act (HR.230), which would ban chlorpyrifos from any commerce in the state. These Senate and House bills follow on previous iterations filed by Sen. Udall and Rep. Velázquez, as well as other legislative initiatives, chronicled here. Rep. Velázquez said of the bill, “It’s unconscionable for EPA to turn a blind eye as children and workers are exposed to this poison. If the EPA won’t do its job when it comes to chlorpyrifos, then Congress needs to act — and do so quickly. As long as there are efforts underway in the courts or administratively to undo the ban on this toxic pesticide, I’ll be working to see chlorpyrifos removed from commerce through the legislative process.”

Momentum is growing for better protection from pesticide use, as these examples and others demonstrate. But ultimately, the widespread adoption of organic management practices is what will provide genuine and long-term protection of human and environmental health from compounds like chlorpyrifos and chlorothalonil. Beyond Pesticides has long sought a broad-scale marketplace transition to organic practices, which prohibit the use of toxic synthetic pesticides. Organic production is a viable, scalable, cost-effective method without any of the long-associated harm of conventional agriculture, but it requires public advocacy to move government to act effectively on behalf of public health and environmental integrity.
