(Beyond Pesticides, April 22, 2025) While it has been widely found that farmworkers bear the brunt of agricultural pesticide exposures in fields and outbuildings, the outdoor use of chemicals contaminating living spaces is documented in an increasing number of studies. Two recent studies add to earlier findings that raise exposure and health concerns. A large European study of house dust contaminants, published in Science of the Total Environment, finds more than 1,200 anthropogenic compounds, including numerous organophosphates, the phthalate DEHP, PCBs, pharmaceuticals, and personal care products. And, a recent Argentine study, “Pesticide contamination in indoor home dust: A pilot study of non-occupational exposure in Argentina,” examines contaminant levels in household dust in villages and towns distributed throughout the Pampas region, where soybeans, corn, sunflowers, and livestock, especially cattle, are raised. The study participants were not agricultural workers, but teachers, government workers, librarians, retirees, college students, doctors, lawyers, artists, and business people. The Argentine study reinforces what has been previously reported, which emphasizes findings that there is no doubt that pesticide residues accumulate in homes adjacent to agricultural fields and pastures. For example, in 2023, Beyond Pesticides reported on a study of 598 California homes near agricultural areas sampled for carpet […]

(Beyond Pesticides, March 28, 2025) The Rhine Valley in southwestern Germany is renowned for the agricultural bounty it has provided for centuries. Today, the area is home to dense wine, vegetable, fruit, and cereal cultivation. However, a study shows that current regulation of pesticides, even in the relatively progressive European Union, is inadequate to protect humans and all the other organisms that produce the environment necessary for human life and civilization.  The study goal was to determine how far—and which—pesticides traveled beyond the croplands of vegetables, fruit orchards, and cereals, as well forested lands, into nontarget areas that should serve as refugia for plants, animals, and invertebrates not considered pests. Based at the Landau Institute for Environmental Sciences at the University of Kaiserslautern-Landau, the researchers used innovative methods to measure the types, concentrations, and distribution of pesticides. They took samples from three landscape categories—vegetation, topsoil, and surface water—at 78 sites distributed along six transects, each reaching from the valley floor to the tops of the mountains on either side. Samples were taken from grasses, shrub leaves, and topsoils along each transect, together with water samples from rivers, small streams, ponds, and puddles. They tested for 93 current-use pesticides (CUPs). There […]

(Beyond Pesticides, December 5, 2024) A novel, comprehensive study published in Science reviews a library of 1,024 different chemicals (herbicides, insecticides, fungicides, and plant inhibitors) finding that, even at “sublethal” exposure levels, 57% of tested chemicals impact the behavioral and physiological health of house fly larvae. Mosquito and butterfly populations are also susceptible to long-term adverse effects at sublethal levels. Environmental and public health advocates continue to raise concerns about adverse effects resulting from the failure of the U.S. Environmental Protection Agency (EPA) to consider cumulative exposure (resulting in aggregate and synergistic effects) across different mechanisms of toxicity and different classes of pesticides, including at exposure levels below allowable levels set by the agency. In the context of the regulatory gaps and pesticide industry influence at EPA (See Daily News here), advocates stress the importance of transitioning land and agricultural practices to organic principles. Methodology and Results  Background, Goals, Primary Takeaways  This research was led by an international team of experts from various universities and institutes, including European Molecular Biology Laboratory (EMBL), Institut Pasteur, and Heidelberg University (Center for Infectious Diseases, Parasitology Department). The authors received funding from the European Molecular Biology Laboratory, the German Center for Infection Research, and […]

(Beyond Pesticides, August 30, 2024) There is no more compelling reason to embrace a precautionary pesticide poisoning standard this Labor Day than the need to protect workers. In fact, the Occupational Safety and Health Administration (OSHA) says on its website, Transitioning to Safer Chemicals, that the best way to protect workers is to  “eliminate or reduce hazardous chemicals at the source.” While some try to employ product substitution with “safer” chemicals, Beyond Pesticides urges decision makers to embrace alternative systems, such as organic management systems, that embrace management techniques to meet disease and infestation management goals and use only organic compatible substances. According to OSHA: “In chemical management, [the industrial hygiene principle, known as the hierarchy of controls] guides employers and workers to eliminate or reduce hazardous chemicals at the source by substituting them with safer alternatives. Unlike traditional engineering controls, administrative controls, work practice controls, or personal protective equipment, these strategies can completely eliminate exposure to hazardous chemicals, reduce the potential for chemical accidents, reduce disposal costs, and remove concerns regarding worker compliance and equipment maintenance.” A look through the state and federal databases that track occupational pesticide poisoning for both acute (immediate short-term) and chronic (long-term) pesticide effects […]

(Beyond Pesticides, July 16, 2024) Yet another study in the August 2024 journal Ecotoxicology and Environmental Safety has found that exposure to organophosphorus pesticides (OPPs) is correlated with increased suicidal thoughts in some people. This study is just the latest in a long line of studies from around the world that have linked pesticide exposure to mental health conditions, including sleep disorders, depression, and suicidal ideation (SI). As the rate of suicide increased by 30% between 2000 and 2020, there is an urgent public health need to investigate and address all potential contributing factors. A 2019 study, covered in Daily News, found that teens and adolescents living in agricultural areas and exposed to organophosphate (OP) insecticides are at higher risk of depression, In July and January this year, other studies link farmer psychiatric episodes to pesticide exposure, adding to the body of science. Exposure to household pesticides is also linked to depression in a 2020 study.   Study and Methodology  The study entitled “Association between exposure to organophosphorus pesticide and suicidal ideation among U.S. adults: A population-based study,” analyzes information on the mental and physical health of over 5,000 individuals aged 20 and up in the United States. The study aims […]

(Beyond Pesticides, June 27, 2024) Earlier this month, Public Employees for Environmental Responsibility (PEER) filed a lawsuit against the U.S. Environmental Protection Agency (EPA) on behalf of a group of ranchers and farmers in Texas harmed by biosolids contaminated with per- and polyfluoroalkyl substances (PFAS). The plaintiffs charge that their health and livelihoods were severely damaged due to contaminated biosolids leaching from neighboring properties onto their land. Despite EPA’s responsibility under the Clean Water Act (Section 405(d) and 40 CFR Part 503) to identify toxic pollutants in biosolids and regulate them to protect human health and the environment, the agency has not effectively addressed the dangers posed by PFAS in biosolid fertilizers. EPA’s failure has dramatic impacts on farmers as well as the public, who are eating or drinking PFAS-contaminated crops, dairy milk, beef, or other meat products. The shortcomings of federal regulations underscore the urgent need for a shift in how federal and state agencies approach these issues, prioritizing precaution to prevent future harm. The persistence of these legacy or “forever” chemicals in the environment illustrates the severe consequences of a historically lax regulatory framework in the U.S.  The National Association of State Departments of Agriculture (NASDA) has identified […]

(Beyond Pesticides, June 13, 2024) A study published in Conservation Letters, a journal of the Society for Conservation Biology, exposes critical shortcomings in the U.S. Environmental Protection Agency’s (EPA) ecological risk assessment (ERA) process for modeling the risks that pesticides pose to bees and other pollinators. For the study, “Risk assessments underestimate threat of pesticides to wild bees,” researchers conducted a meta-analysis of toxicity data in EPA’s ECOTOX knowledgebase (ECOTOX), an EPA-hosted, publicly available resource with information on adverse effects of single chemical stressors to certain aquatic and terrestrial species. The meta-analysis found that the agency’s approach, which relies heavily on honey bee data from controlled laboratory studies, drastically underestimates the real-world threats from neonicotinoid insecticides (and likely other pesticides) to native bees and other pollinators. The study “challenges the reliability of surrogate species as predictors when extrapolating pesticide toxicity data to wild pollinators and recommends solutions to address the (a)biotic interactions occurring in nature that make such extrapolations unreliable in the ERA process.” Beyond Pesticides executive director Jay Feldman remarked, “EPA’s ecological risk assessment process is fundamentally flawed and puts thousands of bee species at risk of pesticide-caused population declines and extinctions.” Mr. Feldman continued, “This underscores the urgent […]

(Beyond Pesticides, June 11, 2024) Published in Science of The Total Environment in May, a comprehensive literature review of population-based studies finds strong linkages between direct and acute pesticide exposure and elevated risk of breast cancer (BC). A majority of the studies analyzed in this review were based on population groups in the United States, but also extends to Australia and three European countries (Greece, France, and Italy). Included in these studies are women who worked in chemical-intensive agricultural settings, directly sprayed pesticides in their at-home gardens, and/or handled pesticide-contaminated clothing. The findings in this literature review underscore organic advocates’ concerns of relying on pesticide substitution models that inevitably impact the health of land stewards, farmers, farmworkers, and the broader public rather than transforming food systems to an organic model that bans the use of toxic petrochemical-based pesticides. The goal of this review was to synthesize existing literature on pesticide exposure and breast cancer to determine the specific pathways and underlying mechanisms that contribute to female participants’ heightened risk. This literature review was published online by researchers at the University of Arizona’s R. Ken Coit College of Pharmacy and Coit Center for Longevity and Neurotherapeutics and the Laboratory of Tumor […]

(Beyond Pesticides, May 17, 2024) Massachusetts Governor Maura Healey (D) proclaimed May 12 -18, 2024 as Multiple Chemical Sensitivity Awareness Week, first established in 1998 in numerous states across the U.S. Multiple Chemical Sensitivity (MCS)—also called chemical intolerance or Toxicant-Induced Loss of Tolerance (TILT), is characterized by disorders in one or more body systems, including respiratory, gastrointestinal, musculoskeletal, and neurological processes. It is thought to be caused by adverse reactions to environmental chemicals and/or biological substances such as mold. Affected individuals suffer fatigue, rashes, muscle and joint pains, memory loss, and other symptoms. The Massachusetts proclamation encourages “residents of the commonwealth to take cognizance” of the event and recognize the distress of their fellow citizens who suffer from MCS. May 12 is also known as International May 12th Awareness Day, an observance started in 2006 in the United Kingdom to educate the public about many diseases associated with sensitivity to chemicals, including MCS, fibromyalgia, and Gulf War Syndrome. While some scientists have considered MCS a psychological or psychosomatic problem, there is increasing support for the reality of MCS as a physical disease distinct from mental or emotional disorders. Yet there are no medical tests that can reliably confirm a diagnosis, […]

(Beyond Pesticides, May 15, 2024) A study published recently in the journal Environmental Research finds a significant correlation between exposure to certain pesticides and an elevated risk of inflammatory bowel disease (IBD), a chronic autoimmune condition of the gastrointestinal tract. The study, adding to the body of science on this subject, evaluates self-reported data from licensed pesticide applicators and their spouses exposed to pesticides for over 20 years. In addition, while some of the chemicals found to be most closely associated with incidents of IBD have been banned from use, they are “forever” chemicals that persist in the environment for generations. These findings demonstrate once again the failings of the current regulatory process to identify hazards before they are put into the environment. The study found evidence that exposure to several organochlorine insecticides (dieldrin, DDT, and toxaphene), as well as organophosphate insecticides (parathion, terbufos, and phorate) and herbicides (2,4,5-T, 2,4,5-TP, and metolachlor), is associated with elevated IBD risk. IBD is a generic term for diseases that result in chronic inflammation of the gastrointestinal tract, such as Crohn’s disease and ulcerative colitis. It is estimated that 6.8 million patients globally suffered from IBD in 2017. IBD may result from an imbalance […]

(Beyond Pesticides, May 8, 2024) In an unexpected turnaround, the U.S. Environmental Protection Agency (EPA) announced at the end of April a Proposed Interim Decision (PID) to discontinue all but one application of the insecticide acephate. Acephate is an organophosphate pesticide, a well-known neurotoxicant, widely banned globally, including in the European Union. Under the proposal, all uses would end except for the injection of trees that do not produce fruit or nuts. In its proposed action, EPA asks the manufacturer to offer the agency a voluntary settlement, a process that typically compromises the health of the public, workers, and the environment. Acephate, an organophosphate (OP) pesticide, is approved for use in both agricultural settings, including crops like cotton and soybeans, and nonagricultural applications, such as injections for forestry trees. Acephate affects the nervous system by inhibiting the acetylcholinesterase (AChE) enzyme. Importantly, chronic, low levels of exposure can cause a range of adverse human health outcomes, from cancer to birth defects, reproductive and developmental problems, and learning disabilities. While the proposed April interim decision, if it comes to pass, is welcomed by advocates, some are concerned that EPA’s proposal does not fully critique the scientific documents and conclusions on risk that […]

(Beyond Pesticides, May 7, 2024) The marginal user costs (MUC) of pesticide resistance for chemical-intensive farmers and the pest management industry are significantly affected by pesticide costs, density dependence (growth rate of a pest population impacted by its density), and dominant genetic mutations that cause resistance, according to a novel study published in Journal of the Agricultural and Applied Economics Association. Although the authors believe that integrated pest management (IPM) can be fine-tuned based on these findings, many advocates believe that these findings in fact underscore the importance of eliminating toxic pesticide use amidst compounding climate, biodiversity, and public health crises—which many IPM strategies do not adequately address. As the costs of petrochemical-based pesticides increase, organisms identified as pests continue to increase in population density as global and regional temperatures dually increase. Organic agriculture, and organic land management principles more broadly, are an economically and ecologically advantageous leap ahead in transitioning to a food system that moves beyond the status quo that poisons people and the planet. “This paper seeks to develop a better understanding of how the user costs of resistance are potentially determined by the interactions of heterogeneous bioeconomic factors that vary by context,” say the study authors. […]

(Beyond Pesticides, April 26, 2024) Researchers build on existing research when assessing the relationship between long-term exposure to organophosphorus pesticides—widely used in food production and homes and gardens—and the human gut microbiome. In a new study published in Environmental Health, an interdisciplinary research team from University of California, Los Angeles determined, “that exposure to [organophosphorus pesticides] is associated with changes in the abundance of several bacterial groups and differential functional capacity in metabolic pathways supported by the human gut microbiome.” The study draws upon data from a “Parkinson’s, Environment and Gene study (PEG)” in which 190 participants were asked to submit fecal samples and answer interview questions. “[The study] was initially designed to investigate the etiology of Parkinson’s disease (PD) and participants were recruited in two study waves [‘over the full 10-year exposure window’]: 2001–2007 and 2012–2017. At baseline, [Parkinson’s disease] patients were diagnosed within the past 5 years and randomly selected community controls were also recruited,” the research team shares in their Methodology section. “Since 2017, we invited previous study participants who could be contacted to enroll in a pilot study of the gut microbiome. In addition, we invited a household or community member of [Parkinson’s] patients to participate.” […]

(Beyond Pesticides, April 11, 2024) Scientists are moving forward in testing an agroecological method of “push-pull” pest management (reducing the attractiveness of the target organism and luring pest insects towards a trap) to fight the Asian citrus psyllid (ACP) in Florida orange groves, as it spreads a plant disease known as the pathogenic bacteria huanglongbing (HLB), also known as citrus greening, which is deadly to citrus trees. The disease is spread by the pathogenic bacteria Candidatus Liberibacter asiaticus (CLas).  The chemical-intensive, or conventional, citrus industry is under intense pressure to find alternatives, as synthetic antibiotic use for this purpose has been successfully challenged in court. ACP is the carrier, or vector, for HLB, spreading it through the citrus groves and killing the trees. The chemical-intensive industry has focused on using antibiotics, which the environmental and public health community has rejected because of serious medical concerns associated with life-threatening bacterial resistance to antibiotics used to protect humans. A federal district court decision in December 2023 found illegal the U.S. Environmental Protection Agency’s (EPA) decision to register the antibiotic streptomycin in Florida citrus without adequate review of its impact on endangered species. The streptomycin lawsuit, filed in 2021 by a coalition of […]

(Beyond Pesticides, April 10, 2024) Researchers in a 2024 Chemosphere study find synergistic relationships in certain chemical mixtures, particularly heptachlor and triallate and trifluralin and lindane at lower concentrations, respectively. “Investigators should consider additional binary data for acute toxicity and potential chronic health impacts on these mixture…which showed synergism at low levels,” the researchers conclude. “According to a Centers for Disease Control (CDC) assessment, more than 50 pesticides are detected in blood or urine samples from the US population,” Researchers point to a cause for concern. The findings come as no surprise to advocates who have urged an assessment of the potential synergistic impacts of pesticide mixtures in the regulation of pesticides. Researchers “used the exposure data from a complex operating site with legacy pesticide pollution to evaluate if Inhalation of pesticide mixtures released from such contaminated sites could pose a risk to human health, The component-based risk assessment approaches that rely on additivity can predict the actual risk of pesticides in a mixture, and The legacy organochlorine pesticides banned many years ago interact with registered and supposedly safe herbicides in a mixture.” The study site is “a pesticide packaging and handling facility” contaminated with the following pesticides (“historical and […]

(Beyond Pesticides, April 9, 2024) The United States Court of Appeals for the Fifth Circuit, in an opinion authored by Circuit Judge Cory T. Wilson, has vacated an action by the U.S. Environmental Protection  Agency (EPA) that had ordered the Texas-based manufacturer Inhance Technologies, L.L.C. to stop producing plastic containers that leach toxic per- and polyfluoroalkyl substances (PFAS) into pesticides, household cleaners, condiments, and additional products. EPA has taken action after the agency determined that the PFAS created during the fluorination process “are highly toxic and present unreasonable risks that cannot be prevented other than through prohibition of manufacture.” While the court is not challenging EPA’s authority to determine the hazards associated with PFAS exposure to be unacceptable, on a technicality, it is finding that the agency used the wrong section of the Toxic Substances Control Act (TSCA), Section 5, which the court says is focused on new uses. According to the Court, “The EPA is just not allowed to skirt the framework set by Congress by arbitrarily deeming Inhance’s decades-old fluorination process a “significant new use,” even though EPA’s awareness of the PFAS contamination was “new” to the agency and not disclosed by the manufacturer. Even if EPA were […]

(Beyond Pesticides, April 5, 2024) Exposure to chemical toxicants, molds, and algae contributes to autism and attention disorders in children, according to research that bolsters earlier findings. The exposures may be most relevant, not in the children, but one generation back—in the parents. The study, “Assessing Chemical Intolerance in Parents Predicts the Risk of Autism and ADHD in Their Children,” was published in the March issue of the Journal of Xenobiotics. Led by Claudia S. Miller, MD, an immunologist at the University of Texas at San Antonio noted for her work on chemical intolerance (CI), the authors build on previous work published in 2015 establishing parental CI as a risk factor for autism and ADHD. Dr. Miller participated in Beyond Pesticides’ 2022 Forum Series. Recordings of her presentation are available on YouTube here and here. In 1996, Dr. Miller concluded that CI is induced by Toxicant-Induced Loss of Tolerance (TILT). For further details, see Beyond Pesticides’ Daily News Blog. Three years later Dr. Miller developed the Quick Environmental Exposure and Sensitivity Inventory (QEESI), a questionnaire for individuals tracing their toxicant exposures and symptom histories. QEESI was first developed with groups exposed to organophosphate pesticides, volatile organic compounds in reconstruction and […]

(Beyond Pesticides, April 4, 2024) Researchers at the National Institute of Pediatrics and National Polytechnic Institute found positive associations between pesticide exposure and heightened risk of certain childhood cancers. The finding is derived from a meta-analysis of 174 studies published between 2013 and 2023 and published in the International Journal of Molecular Science. The authors note, “Although [pesticide exposure] association with childhood cancer has not been fully demonstrated, we found that more than 80% of the epidemiological studies show positive associations [with forms of childhood cancer].” Approximately one third of identified studies (roughly 16) find positive relationships between prenatal and postnatal pesticide exposure with heightened risk of leukemia, neuroblastoma, and rare forms of cancer, such as Wilms tumor. For central nervous system (CNS) tumors, half of identified studies (roughly 24) found a positive relationship with pesticide exposure. The researchers call on further research regarding interaction between different pesticides and health impacts on cumulative exposure. The study is broad in scope, identifying various environmental pollutants and their associations with certain childhood cancers (e.g. radon exposure, air pollution, electromagnetic fields, indoor chemicals, and tobacco and alcohol). This Daily News focuses specifically on pesticide exposure. The researchers originally identified 6,172 studies through PubMed, however […]

(Beyond Pesticides, March 27, 2024) A preliminary experiment conducted by Public Employees for Environmental Responsibility (PEER) reveals concerning levels of toxic per- and polyfluoroalkyl substances (PFAS) on the skin of soccer players and coaches after playing on artificial turf fields. The Washington Post reported on March 12 on the PEER test results, which found PFAS levels increased on the skin in three out of four participants following soccer matches on artificial turf. In contrast, no similar increase was observed after games on natural grass fields. The presence of PFAS is alarming due to their association with several serious health issues, including cancer, birth defects, and developmental and immune deficiencies, among others. The U.S. Environmental Protection Agency (EPA) writes that PFAS exposure risks are particularly concerning for young children, who are more susceptible due to their developing bodies and at risk for higher levels of exposure than adults. Known as “forever chemicals” for their persistence in the environment, PFAS continue to accumulate in the human body, posing long-term health risks. Kyla Bennett, PhD, science policy director at PEER and a former scientist and lawyer with EPA, emphasized the need for further research. “Although this study is preliminary, it highlights the potential […]

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

(Beyond Pesticides, March 4, 2024) With 14.7 million children and adolescents in the U.S. recognized as obese by the Centers for Disease Control and Prevention (CDC) and the established connection with endocrine disrupting contaminants, including many pesticides, Beyond Pesticides is calling on federal food assistance programs to go organic. The problem of childhood obesity is higher in people of color and, as a result, is an environmental justice issue. According to CDC, the prevalence of childhood obesity is “26.2% among Hispanic children, 24.8% among non-Hispanic Black children, 16.6% among non-Hispanic White children, and 9.0% among non-Hispanic Asian children.” While childhood obesity is recognized as a serious problem, the National School Lunch Program of the U.S. Department of Agriculture (USDA)—although improved by the Healthy, Hunger-Free Kids Act of 2010—still provides lunches laced with obesogenic pesticides. To take meaningful steps against childhood obesity, school lunches must be organic. The program served 4.9 billion meals in fiscal year 2022 in over 100,000 public and nonprofit schools, grades Pre-Kindergarten-12. Contrary to popular opinion, the blame for the obesity epidemic cannot be attributed solely to diet and exercise broadly, but relates directly to pesticide and toxic chemical exposures, including residues in food, that may lead […]

(Beyond Pesticides, November 15, 2023) A study previously published in the Federation of American Societies for Experimental Biology (FASEB) is drawing renewed attention to the gut microbiome in the scientific community. The study, involving a team including Demetrio Sierra-Mercado, PhD, of the University of Puerto Rico School of Medicine, initially established a link between glyphosate exposure and increased anxiety and fear-related behavior in rats. Glyphosate, a widely-used herbicide, has been detected in trace amounts in fruits, vegetables, grains, and other food and beverages, according to the U.S. Environmental Protection Agency (EPA). Originally deemed safe for humans due to the way it interacts with the shikimic acid pathway—a metabolic route that is absent in humans—glyphosate’s indirect effects on human health are now under scrutiny as the research linking it to anxiety-like behavior grows.  Dr. Sierra-Mercado’s team is expanding on his previous research to take a closer look at the compound’s potential disruption of the gut microbiome, which plays a pivotal role in regulating both physical and mental health. His upcoming study, anticipated in August 2024, aims to delve into the intricate relationship between glyphosate exposure and the gut-brain axis, with a focus on how this may influence neurological and emotional health […]

(Beyond Pesticides, November 14, 2023) One of the Environmental Protection Agency’s (EPA) strongest tools for avoiding responsibility is delay—a tactic that kept cancellation of the neurotoxic pesticide chlorpyrifos at bay for 21 years—until May 2021, when a three-judge panel of the Ninth Circuit Court of Appeals, responded to a petition filed in 2007 by the Natural Resources Defense Council, Pesticide Action Network, and numerous other groups. The Ninth Circuit ordered the agency to quit lollygagging and acknowledge chlorpyrifos’s threat to human health, something the agency had acknowledged already. The Ninth Circuit instructed EPA to either revoke the “safe” tolerances the agency had set for chlorpyrifos’s residue in various foods or demonstrate that they are actually safe. Finally capitulating, EPA issued a final rule in August 2021 revoking all food tolerances for the neurotoxicant. Tell your governor and mayor to adopt policies that support organic land management.  This looked like progress until February 2022, when a different set of petitioners—pesticide companies, U.S. farmer groups, and other countries’ agricultural interests—filed an action in the Eighth Circuit Court of Appeals. On November 3 of this year, a three-judge panel of the Eighth Circuit reversed EPA’s decision, thereby neutralizing the Ninth Circuit’s opinion. Chlorpyrifos, […]
