(Beyond Pesticides, January 12, 2026) With a pattern of chemical industry deception of independent scientific review, and the recent retraction of an influential Monsanto ghostwritten article (April 2000) on the weed killer glyphosate (Roundup™), Beyond Pesticides and its network are calling for oversight hearings in Congress. At issue is the reliance of the U.S. Environmental Protection Agency (EPA) on industry data and agency collusion with chemical manufacturers on its decisions. Beyond Pesticides is questioning the underlying reliability of the data, in addition to limitations of the regulatory review process in meeting its statutory duty to protect health and the environment. In addition to the deception, key underlying deficiencies are EPA’s failure to evaluate endocrine disrupting pesticides and synergistic effects of chemical mixtures. Given these deficiencies and the cost effectiveness of organic land management and crop production Beyond Pesticides is asking Congress to hold oversight hearings to determine how EPA can eliminate the use of toxic pesticides that are no longer needed to grow food or manage landscapes cost-effectively.  Critically, the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and EPA’s pesticide program allow toxic chemicals to be dispersed, resulting in widespread negative impacts, without regard for the availability of cost-effective and profitable alternatives that are eco-sensitive and health protective. Consideration of the essentiality of synthetic substance […]

(Beyond Pesticides, January 6, 2026) Editor’s Note: We begin the new year with a clarion call for meaningful strategies to eliminate petrochemical pesticide and fertilizer use, based on the preponderance of science that documents both the hazards of their use and the abject failure of regulations in the U.S. and worldwide to accurately account for their harm to health and the environment. Over the holiday season, we have been cheered by letters to the editor, one from a pediatrician in Missoula, Montana and another from a student in Cedar Falls, Iowa, calling for the elimination of pesticide use in their communities. This call for action in communities targets the places where we live, work, learn, and play—where critical decisions on the use of poisons and contaminants are being made daily in our parks, playing fields, schools, open space, and other public properties. We have the tools to eliminate pesticide use with defined organic practices and compatible materials. We should accept nothing less. The scientific study we write about today (below) details an outrage of huge proportions, a synergistic effect of chemical interactions of widely used synthetic pyrethroid insecticides in combination with environmental stressors—resulting in adverse effects 70 times greater than when […]

(Beyond Pesticides, December 19, 2025) While still the exception rather than the norm, a growing movement of Christmas tree farmers across the United States is demonstrating that organically managed systems can also be applied when choosing a tree during this holiday season. Health and environmental advocates across the country are calling for a transition away from toxic pesticide dependency during the holiday season. Beyond Pesticides maintains a webpage, Christmas Trees and Pesticides, and Center for Biological Diversity and Alliance of Nurses for Healthy Environments urged the U.S. Environmental Protection Agency and U.S. Department of Health and Human Services to conduct a “special review of pesticides used on Christmas trees.” The groups sent a letter on December 4, the day the National Christmas Tree was lit at the White House, specifically citing the need to review the pesticides chlorpyrifos, carbaryl, dimethoate, bifenthrin, chlorothalonil, glyphosate, hexazinone, imidacloprid, simazine, and 2,4-D, among others. Christmas is one of the most celebrated holidays in the United States, with Christmas trees grown on Christmas tree farms being brought into homes as part of the celebration. On average, Americans purchase 25 to 30 million Christmas trees annually, according to the National Christmas Tree Association; however, certified organic […]

(Beyond Pesticides, December 15, 2025) With recent proposals by the U.S. Environmental Protection Agency (EPA) to register new pesticides that under international standards are classified as PFAS (Per- and Polyfluoroalkyl Substances), people and organizations are calling for Congress to reverse the agency’s action. Beyond Pesticides announced an action to Tell EPA and Congress to eliminate PFAS chemicals, including those used in pesticides.  In its action Beyond Pesticides pointed to the long history of allowing pesticides on that market that have long residual lives and bioaccumulate in the environment, causing generations of exposure and adverse effects to health and ecosystems. DDT (Dichlorodiphenyltrichloroethane) exemplifies the generational effect of a toxic pesticide whose effects ha endured for decades, even though it was hailed as a miracle solution for agriculture and public health. PFAS, with a wide variety of uses—from nonstick pans to waterproofing fabrics to firefighting foams to pesticides—might similarly lead to the characterization as a “miracle” chemical. PFAS also share the less beneficial characteristics of DDT. Like DDT, PFAS are persistent, leading to the nickname “forever chemicals,” and they are highly toxic. EPA links PFAS to an increased risk of many health effects, including decreased fertility and hypertension in pregnant people; increased risk of prostate, […]

(Beyond Pesticides, December 12, 2025) A study concluding that the weed killer glyphosate did not cause cancer was retracted last week after it was revealed in lawsuit documents that the authors did not disclose their relationship with Monsanto/Bayer. The editor-and-chief, Martin van den Berg, PhD of Regulatory Toxicology and Pharmacology, which published the article 25 years ago, wrote in the journal, “Concerns were raised regarding the authorship of this paper, validity of the research findings in the context of misrepresentation of the contributions by the authors and the study sponsor and potential conflicts of interest of the authors.”  The study, titled “Safety Evaluation and Risk Assessment of the Herbicide Roundup and Its Active Ingredient, Glyphosate, for Humans” and coauthored by three researchers in New York, The Netherlands, and Canada, was referred to as a “Landmark glyphosate safety study” in a recent article by U.S. Right to Know.   While this retraction not only sheds light on Monsanto’s influence through ghostwriting, it adds to the wide body of evidence regarding the regulatory deficiencies currently in place. The revelation is a reminder of related incidents in which Monsanto (Bayer) and other companies have wielded excessive influence at the U.S. Environmental Protection Agency (EPA), undermining the integrity of the science needed to inform the regulatory decisions that safeguard health and the environment. (See Daily News Corruption Problems Persist at EPA.)  EPA Deficiencies  In addition to the initial registration process, the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) requires that EPA conduct a registration review of all pesticide […]

(Beyond Pesticides, December 4, 2025) In a news release last week on November 26, 2025, the U.S. Environmental Protection Agency (EPA) “issued a comprehensive fact-check addressing dangerous misinformation circulating about EPA’s recent pesticide approvals” that, according to health and environmental advocates, continues to deceive the public about the true risks for health and the environment from petrochemical pesticides including, but not limited to, per- and polyfluoroalkyl substances (PFAS). Also published on November 26, coverage titled The EPA Is Embracing PFAS Pesticides. These Are The Health Risks in Time further highlights EPA’s deficiencies and the threats of PFAS, which Beyond Pesticides has extensively covered. (See here and here.)  The controversy erupted as a result of EPA’s latest proposal to allow a new fluorinated pesticide to the list of four other similar compounds now widely available for use in homes and gardens, buildings, and agriculture. The newest pesticide proposed for EPA registration, epyrifenacil (agricultural weed killer), joins cyclobutrifluram (soil fungicide/nematicide), isocycloseram (household and agricultural insecticide), diflufenican (lawn and agricultural weed killer), and trifludimoxazin (agricultural weed killer), making a total of five PFAS pesticide proposals this year that have been associated with national and worldwide contamination of food, land, and water. Two of these, cyclobutrifluram and isocycloseram, have been approved. “Instead of constraining the use of fluorinated pesticides—persistent and highly toxic […]

(Beyond Pesticides, November 24, 2025) In his article on ecological traps, Professor Danilo Russo, PhD, explains the harm caused to wildlife from well-intentioned efforts to establish habitat on chemical-intensive farms or areas otherwise subject to chemical exposure. Dr. Russo et al., in “To improve or not to improve? The dilemma of “bat-friendly” farmland potentially becoming an ecological trap” (2024), write, “[W]hen restoring habitats for bats in conventional farmland, potential unintended outcomes must be considered, particularly if restoration actions are not accompanied by mitigation of key threats. These threats include the persistent and widespread use of pesticides. . .” (See also a study in Environmental Entomology, which shows that habitat and open space near agricultural fields become a killing field of pesticides, threatening biodiversity due to contamination from toxic drift.) As this false sense of protection persists, Beyond Pesticides is calling on governors to adopt policies that support organic land management and ecological balance. Organic practices are, by definition, a systems change that is aligned with nature and the biodiversity protection that is needed. Ecological traps are incremental steps that fail to address underlying systemic problems that allow hazards to persist. While they represent an affirmative action in an attempt to adopt restorative measures, the […]

(Beyond Pesticides, November 20, 2025) Recent scientific literature finds heightened toxicity associated with pesticide metabolites, the transformation/breakdown products of the parent compounds, that threaten the health of the soil, wildlife, and humans. This research stresses the importance of the U.S. Environmental Protection Agency (EPA) evaluating metabolites, which is currently insufficiently included in regulatory processes. In a literature review in Global Change Biology, the researchers point out multiple areas in which regulations fail to address key criteria, including metabolites, saying: “Pesticide risk assessments currently rely on surrogate species and focus primarily on acute lethality metrics, failing to capture the broader impacts on non-target organisms and thus biodiversity. Under the directives of regulatory agencies worldwide, this traditional approach overlooks the complex interactions between multiple stressors, including climate change, land-use shifts, and pesticide transformation products. Pesticide risk assessments must therefore undergo a paradigm shift to account for these complex interactions, which disproportionately affect insect pollinators, other non-target species, and biodiversity at large.” A metabolite is a breakdown product that forms when a pesticide is used in the environment and mixes with air, water, soil, or living organisms. All metabolites fall under the category of transformation products, which is the broader term for any […]

(Beyond Pesticides, October 31, 2025) A review in Lancet Neurology provides a clear snapshot of the state of scientific understanding of Parkinson’s disease and how medicine and policy could be improved by shifting focus to the primary causes of the disease, namely environmental toxicants, and to emphasize prevention rather than devoting resources only to treatments and a cure. The study, led by Ray Dorsey, M.D. of the Atria Research and Global Health Institute and the University of Rochester Medical Center, focuses on three classes of environmental toxicants: pesticides, dry cleaning and degreasing chemicals, and air pollution. Because these are pollutants introduced by humans, the authors say, they should be controllable, and “Parkinson’s disease could be thus largely preventable.” According to the review, in the last five years, new evidence has accumulated about three types of pesticides of particular concern. They are not all insecticides, which is the pesticide category most associated with neurological damage. Paraquat is a herbicide used on corn, soybeans, and cotton. Rotenone is used to kill rats and insects. Organochlorine insecticides comprise the third class. The review notes that there are many other pesticides that are neurotoxic and may have common mechanisms of action leading to Parkinson’s and […]

(Beyond Pesticides, October 27, 2025) With the confluence of science and law, the spotlight is on sewage sludge fertilizer and its contaminants, including per- and polyfluoroalkyl substances (PFAS). Sewage sludge (biosolids) is a byproduct of sewage treatment and is used as a source of organic matter for amending soil in nonorganic agriculture and landscaping. In light of a recent settlement in a lawsuit filed by Beyond Pesticides against ScottsMiracle-Gro, ongoing litigation against GreenTechnologies, LLC, and a major study identifying 414 contaminants of emerging concern (CECs), Beyond Pesticides’ network is calling on Governors and local officials to ban the use of biosolids on farms and parks, until there is adequate testing of toxic residues—which does not currently exist.   The lawsuits against producers of sewage sludge fertilizer cite test results showing PFAS residues in the companies’ products and numerous scientific studies on the adverse effects of PFAS to public health, wildlife, and pollinators. (See settlement statement recently reached with ScottsMiracle-Gro.)  A literature review published in Frontiers in Environmental Chemistry identifies CECs in soils, untreated and treated sewage sludge (biosolids), and dust, across 151 peer-reviewed studies released between 2018 and 2023—emphasizing the range of potential exposure pathways across various products, including classes of pesticides like neonicotinoid insecticides. […]

(Beyond Pesticides, October 10-13, 2025) On Indigenous Peoples’ Day (Monday, October 13), Beyond Pesticides acknowledges that we recognize that the land we are situated on is the ancestral lands of the Ncothtank (Anacostan), and neighboring Piscataway and Pamunkey peoples, who have served as stewards for the region’s land, water, and air for generations. In reverence for the sovereignty and leadership of First Nations, and with respect for the wisdom of Indigenous peoples globally, environmental and public health advocates continue to advocate for the elimination of petrochemical-based pesticides and fertilizers, and the advancement of organic regenerative criteria that align with ecologically-based food and land management systems. This year, Indigenous Peoples’ Day falls on the petrochemical fertilizer industry-supported Global Fertilizer Day, which promotes synthetic fertilizers, rather than recognizing the value of agroecology—the shared understanding of the inextricable link that binds agricultural and ecological systems. Reflection of Turbulent U.S. Position on Indigenous Sovereignty The federal holiday on October 13, traditionally known as Columbus Day, has for many been reoriented to recognize that the “discovery” of the Americas was, in fact, an invasion of the Western hemisphere by European colonists who expropriated unceded land and devastated Indigenous cultures, self-governance, and ways of life. In […]

(Beyond Pesticides, September 17, 2025) A study in Environmental Science & Technology finds additive effects of a synthetic pyrethroid insecticide (cypermethrin) and two fungicides (azoxystrobin and prochloraz) on biological control, biomass of major invertebrate trophic groups (position in food web), and soil ecosystem processes in arable systems (land suitable for growing crops). The study authors further highlight the failure of pesticide regulations to consider elaborate trophic interactions and pesticide mixtures, as well as additive and synergistic effects within their assessments, calling attention to the complexity of real-world exposures and the lack of research to fully understand the implications of chemical use for agricultural and land management purposes. “Arable systems have a high dependence on diverse natural biota to support pest control, soil bioturbation, and nutrient recycling,” the researchers write. These communities rely on a balance of organisms within various trophic levels in order to function and provide vital ecosystem services. Disruptions caused by environmental contaminants, such as pesticides to nontarget organisms, impact entire ecosystems and overall biodiversity. As the authors state, current risk assessments underestimate the real-world risks of petrochemical pesticides and synthetic fertilizers that, despite a wide body of science connecting exposure to deleterious health and environmental effects, are […]

(Beyond Pesticides, September 16, 2025) As reported in the Daily News on August 28, the U.S. Environmental Protection Agency (EPA) announced that it “will hold a public webinar [today], September 16, 2025, at 2:00 PM ET to provide information on the ecological runoff/erosion and spray drift mitigation measures that can be used to protect endangered species from pesticides.” This follows closely behind an earlier announcement of a newly released Pesticide App for Label Mitigations (PALM) mobile tool to assist in implementing these mitigation measures. Despite boasting that the PALM tool is a “one-stop shop” for farmers to use EPA’s mitigation menu, which the agency claims helps to protect nontarget species, environmental critics say that self-directed mitigation without a rigorous reporting and enforcement apparatus fails to meet the level of protection that is necessary under the Endangered Species Act (ESA). As Beyond Pesticides has often reported, mitigation measures are not enforced through recordkeeping, inspections, and certification, and require no accountability from farmers and pesticide applicators. At the same time, EPA assumes compliance with mitigation measures as the basis for meeting statutory standards of reasonable risk from harmful chemicals, despite documented health and environmental harm. As a Daily News article earlier this […]

(Beyond Pesticides, September 15, 2025) With residues of the widely used weed killer glyphosate (Roundupᵀᴹ) in the food supply long documented, scientific attention has turned to the synergistic effects of the weedkiller— a magnified effect greater than the individual chemical effects added together. The authors of an article in World’s Poultry Science Journal write, “The synergistic toxic effects of commercial glyphosate formulations and their bioaccumulation in animal tissues are often overlooked in current safety assessments.” Following up on a previous action, Beyond Pesticides is telling Congress and the U.S. Environmental Protection Agency (EPA) that the agency must consider the effects of pesticides in the context in which they are used and promote the organic alternative.  Glyphosate residues in animal feed, as well as in water and through other exposure routes from food generally and residential areas, pose risks to both animal and human health, as these residues can bioaccumulate. As previously examined by Beyond Pesticides, the effects of pesticides are not limited to the crops to which they are applied. Synergistic effects of multiple chemical exposures are the rule, rather than the exception.   With poultry, the herbicide enters the production system through residues in genetically engineered feed. An earlier article in Scientific Reports concludes that glyphosate’s […]

(Beyond Pesticides, September 12, 2025) A team of Argentinian researchers conducted a study published in Environmental Toxicology and Pharmacology of the combined effects of the herbicide glyphosate and the pyrethroid insecticide cypermethrin. The researchers observed significantly higher apoptosis in cells exposed to the mixtures than to the individual pesticides—a synergistic response. Apoptosis, also known as programmed cell death, is a standard way that tissues handle damaged cells to remove threats to their function. The researchers sought to investigate the cellular toxicity of each chemical, individually and in combination, and assessed whether the effects of the mixture were additive or synergistic. Additive effects occur when two individual chemicals amplify the same sort of response, often because the chemicals have similar structures. Synergism can occur when chemicals have different mechanisms of action but work together to create more powerful effects. Mixtures of pesticides are the least-studied area of research conducted for regulatory purposes. While regulators provide instructions to applicators regarding which pesticides can be applied together and combined in tank mixtures, there is no control over how pesticides travel through the environment once applied, as they flow through the air as spray drift, lodge in soils and water, and are incorporated into […]

(Beyond Pesticides, September 10, 2025) After being criticized by the chemical industry and allied agribusiness and service industry groups on the Make America Healthy Again (MAHA) report in May, the strategy document, released yesterday, has tamped down efforts to reform government programs that regulate pesticides. There are no specific recommendations on improving the regulation of pesticides. Rather, the strategy appears to embrace business-as-usual and could even ramp up government efforts to tout the need for pesticides and claims that current regulatory reviews are effective and comprehensive. In a section of the strategy entitled “Increasing Public Awareness and Knowledge,” the document says: “EPA, partnering with food and agricultural stakeholders, will work to ensure that the public has awareness and confidence in EPA’s pesticide robust review procedures and how that relates to the limiting of risk for users and the general public and informs continual improvement.” This is at odds with the earlier MAHA assessment report which identified pesticides as substances of concern that, citing deficiencies in chemical reviews, “may be neglecting potential synergistic effects and cumulative burdens, thereby missing opportunities to translate cumulative risk assessment into the clinical environment in meaningful ways.” While the earlier report, Make Our Children Healthy Again: Assessment, […]

(Beyond Pesticides, September 9, 2025) SprayDays California, the pesticide notification and mapping tool run by the California Department of Pesticide Regulation (DPR), was updated in late August after public backlash (including from farmworkers), which identified inadequate notice of pesticide use to those who work in or live in proximity to agricultural fields. According to a DPR press release from August 28, these changes include attempts to bring down barriers for users so that, in the words of DPR Director Karen Morrison, the department can “provide Californians with access to information and services.” While public health advocates view notification as a step that may allow people to leave a treatment area or take shelter to reduce exposure, groups continue to express concerns about a focus on notification to the exclusion of addressing the root causes of exposure—chemical-intensive agriculture, despite the viability of organic compatible practices and products. The groups criticize the continuous registration of pesticide active ingredients and product formulations without considering widely available practices and nonchemical and nature-based alternatives to pest management. These include regenerative organic principles and practices that draw inspiration from Indigenous land management and agroecological systems that have thrived in coexistence with nature. Recent Updates There are […]

(Beyond Pesticides, September 8, 2025) Beyond Pesticides today called on Congress to require the U.S. Environmental Protection Agency (EPA) to incorporate real world science into its evaluation of pesticide safety calculations by recognizing that daily exposure involves multiple chemicals and synergistic interactions— a magnified effect greater than the individual chemical effects added together. The organization cites numerous scientific studies that call public attention to this issue; that a realistic assessment of the human and environmental harm potentially caused by pesticides cannot be evaluated based on single-chemical, single-species tests. Given the numerous complexities associated with this type of assessment, the group points to organic land management in agriculture and residential areas as a more cost-effective approach, sending this message to Congress: EPA must consider the effects of pesticides in the context in which they are used and with reference to the organic alternative. A recent study, covered by Beyond Pesticides in its Daily News, found that the presence of Varroa mites in combination with the neonicotinoid insecticide imidacloprid increases the risk of bee mortality and disrupts the larval gut microbiome. The study found synergy (a greater combined effect) between Varroa destructor, a parasitic mite that attacks and feeds on honey bees, and imidacloprid. The findings were published last […]

(Beyond Pesticides, September 4, 2025) A review of agricultural neonicotinoid insecticide regulations, published in Pest Management Science, evaluates the varied approaches being taken for bans and exemption-based restrictions in the European Union (EU), Canada, and the United States (U.S.). Despite an ever-growing and overwhelming body of science linking neonicotinoids (neonics) to adverse effects on pollinators and other nontarget species, the regulations fall short in protecting the environment and wildlife. The review, with the history and current status of neonics, lends further support for a full transition to organic agriculture and land management that removes neonicotinoid exposure routes and subsequent health threats. With the application of this widely used class of neurotoxic system insecticides increasing, so too has the concern over the long-term chronic effects on pollinators and other species from exposure. This concern, backed by scientific literature, has “led to increased governmental regulations since the mid-2010s, particularly in agricultural settings,” state the authors from Iowa State University and Washington State University. They continue, “These regulations have varied in terms of approach, geography, and timeline, starting with a ban implemented by the European Union (EU) and evolving into exemption-based regulations across two Canadian provinces and five U.S. states as of this […]

(Beyond Pesticides, August 28, 2025) The U.S. Environmental Protection Agency (EPA) on August 12, 2025, released a statement, “EPA Announces Action to Protect Endangered Species from Insecticide Methomyl,” in which the agency announced label changes for methomyl, a carbamate insecticide, with mitigation measures that are being criticized as allowing great risks to biodiversity and human health. The label changes, following the National Marine Fisheries Service’s (NMFS) final biological opinion issued on January 1, 2024, actually establish mitigation measures to be determined by applicators using the Bulletins Live! Two website prior to use. EPA claims that this grower determined action will meet the standards of the Endangered Species Act (ESA) by “reduc[ing] runoff and spray drift from treated areas into species’ habitats.” However, the process does not include monitoring and oversight to determine whether the rigorous standards of ESA are being met. The agency says that mitigation tracking is “at the field or farm level,” but it is not required to be submitted to the agency. EPA announced on August 20 that it is holding a 90-minute public webinar on September 16, 2025, at 2:00 PM ET to provide information on the ecological runoff/erosion and spray drift mitigation measures that can […]

(Beyond Pesticides, August 22, 2025) Legislative language moving through Congress—intended to prevent farmers, consumers, and workers from holding pesticide manufacturers accountable for the harm caused by their toxic products—is being opposed by a broad coalition of farmers, beekeepers, consumers, environmentalists, and workers with the release today of a joint statement opposing a dramatic change in a fundamental legal right. The document, Protect the Right of Farmers, Consumers, and Workers to Hold Pesticide Companies Accountable for Their Harmful Products, is joined by 51 organizations, coalitions, businesses, and leaders representing tens of thousands of members and communities. The legislation at issue is hidden in a provision of the Appropriations bill (Section 453) that has passed through the Appropriations Committee in the U.S. House of Representatives and is headed for a vote of the full House in the next couple of weeks, followed by the U.S. Senate. The Appropriations provision is being pushed by chemical companies in the wake of extraordinary jury verdicts against Bayer/Monsanto, amounting to billions of dollars in compensatory and punitive damages, for “failure-to-warn” liability claims involving glyphosate (Roundupᵀᴹ) weed killer products. The pesticide has been classified as cancer-causing by the International Agency for Research on Cancer (a part of […]

(Beyond Pesticides, August 18, 2025)  With pesticide manufacturers pushing to stop cancer victims (and others suffering adverse effects) from suing them under longstanding ”failure to warn law,“ U.S. Senator Cory Booker (D-NJ) is proposing to uphold this unequivocal right to protection. Senator Booker has introduced the Pesticide Injury Accountability Act (S. 2324) to protect the rights of farmers and consumers to hold pesticide manufacturers responsible for the harm caused by their toxic products. This effort comes in the wake of congressional and state legislative attacks on “failure-to-warn” liability claims that are taking place in response to extraordinary jury verdicts against Bayer/Monsanto for harm caused by glyphosate weed killer products like Roundup.ᵀᴹ 📣 Beyond Pesticides, with allied organizations across the U.S., is asking the public to “Tell your U.S. Senator to co-sponsor S. 2324, the Pesticide Injury Accountability Act.” This bill will amend the Federal Insecticide, Fungicide, and Rodenticide Act of 1972 (FIFRA) to create a federal right of action for anyone who is harmed by a toxic pesticide.  Despite growing peer-reviewed scientific evidence linking widely used pesticides to a host of health harms, including cancers, birth defects, endocrine disruption, Parkinson’s disease, and infertility, the chemical industry and its allies in elective office are pushing to deny victims access to […]

(Beyond Pesticides, August 13, 2025) The data on the adverse effects of the insecticide chlorpyrifos, still widely used in food production, continued to accumulate with the latest being a study published in PLOS One that finds perinatal exposure to the chemical in mice can alter sleeping patterns, lead to brain inflammation (particularly in female individuals), and impact gene expression linked to immune response and epigenetic effects. The adverse health effects are greater overall in female mice than male mice, emphasizing the significance of disproportionate impacts across species. Chlorpyrifos has been a threat to human and ecological health for decades, originally as a general-use pesticide for homes, gardens, and agriculture, and then restricted to most nonresidential uses in 2000. Currently, the chemical’s permitted uses include food and feed crops, golf courses, as a non-structural wood treatment, and adult mosquito control for public health (insect-borne diseases) uses only. According to health and environmental advocates, there is a long history of U.S. Environmental Protection Agency (EPA) failure to adequately protect human and environmental health from chlorpyrifos, which is linked to endocrine disruption, reproductive effects, neurotoxicity, brain, kidney, and liver damage, and birth and developmental effects. It took 21 years after negotiating a stop […]
