Study Shows Widely Used Weed Killer To Contain PFAS, Further Threatening Health and the Environment

(Beyond Pesticides, March 13, 2026) In a press release on March 10, 2026, Public Employees for Environmental Responsibility (PEER) cites independent test data on the herbicide indaziflam with detections of per- and poly-fluoroalkyl substances (PFAS), the “forever chemicals” known for significant toxicity at low level exposure and high persistence. The product, Rejuvra™, is produced by Envu (a former division of Bayer) and “is being sprayed and considered for use across millions of acres of Bureau of Land Management (BLM) and US Forest Service land.” Scientific literature connects indaziflam and PFAS with adverse effects to human, soil, and biodiversity health, raising serious concerns about their wide use in agriculture and general land management of lawns, parks, playing fields, ornamentals, fence lines, rights-of-way, rangeland, open space, and Christmas trees. Background As a pre-emergent weed killer used to kill annual grasses and unwanted broadleaf plants, the fluoroalkyltriazine herbicide is broadly labeled for use in residential areas, commercial ornamental and sod production, forestry, and mostly orchard crops. While indaziflam is considered a “selective” herbicide, it actually kills and prevents germination of a wide range of broad-leaved plants and grasses and comes close to being a soil sterilant.  Since the chemical is subject to drift […]

Pesticide Exposure Again Linked to Neurotoxic Effects in Humans and Wildlife in Comprehensive Review

(Beyond Pesticides, March 12, 2026) The science connecting pesticide exposure to neurotoxicity continues to mount. A study in Discover Toxicology highlights neurotoxic pollutants as significant environmental threats, showcasing the adverse impacts on vertebrates’ neurological health from pesticides, including organophosphates, carbamates, and organochlorines. “These substances disrupt normal neurophysiological functions by impairing neurotransmission, generating oxidative stress, provoking neuroinflammation, and initiating neuronal cell death,” the authors say. They continue, “Such disturbances are linked to cognitive deficits, motor impairments, and abnormal neural development.” Neurological conditions can manifest as headaches, muscle weakness, tremors, paralysis, coordination challenges, vision loss, hallucinations, vertigo, seizures, memory loss, slurred speech, trouble breathing with minimal exertion, and more. The range of adverse effects from low-dose, long-term exposure and low-dose (or subchronic) exposure during developmental phases of life raises serious questions about the adequacy of the regulatory review of pesticides, which focuses on acute high and lethal dose exposure. One study on the neurotoxicity of pesticides, published in Chemosphere, concludes, “New regulatory and preventive measures to mitigate the neurotoxic effects of pesticides are needed.” (See also Daily News.) Even at low concentration, chronic exposure to pesticides and other environmental contaminants “poses serious ecological and health concerns” that occur as these chemicals “bioaccumulate […]

Pesticide and Antibiotic Resistance Genes: An Escalating Global Health Crisis

(Beyond Pesticides, March 10, 2026) An article in the Journal of Agricultural and Food Chemistry identifies pesticides, often neglected, as a core factor in the spread of antibiotic resistance genes (ARGs) in agricultural environments. With antibiotic and antimicrobial resistance growing and infections becoming untreatable and deadly, the World Health Organization (WHO) has identified the problem as a “silent pandemic.” The authors, from Yangzhou University in China, highlight the persistence of both pesticide residues and ARGs throughout the environment, with both being found in water, soil, air, animal manure, and the human gut. “Existing studies have fully confirmed that pesticides are not isolated in the agricultural ecosystem but deeply participate in the proliferation and spread of ARGs through direct coselection, indirect induction of multiple resistances, and promotion of horizontal gene transfer, forming a combined pollution risk that superimposes on the traditional sources,” the authors note. The now well-known phenomenon of horizontal gene transfer—the movement of genes in bacteria from one bacterial species to another, which is facilitated by phages—means that ARGs in those (possibly harmless) bacteria can move to bacteria that cause disease in plants or humans. As stated in previous Daily News posts, pesticides by themselves are a grave threat […]

EPA Asked to Deny Proposal To Use a New Not-Registered PFAS Pesticide under “Emergency” Waiver

(Beyond Pesticides, March 9, 2026) Policy and toxicology are slated to collide as the U.S. Environmental Protection Agency (EPA) considers allowing the use of a PFAS pesticide by invoking an emergency waiver process in federal pesticide law. If authorized, EPA’s decision will permit the use of an unregistered pesticide under an emergency waiver provision—in this case an emergency caused by weed resistance to weed killers (herbicides) on the market. EPA is accepting public comments until March 16, 11:59pm EDT. Beyond Pesticides is urging the public to object to EPA approval by writing to EPA and Congress stating that herbicide resistance is not an emergency and PFAS chemicals must not be broadcast in the environment.  The pesticide that is being requested for use is a new not yet registered, herbicide tetflupyrolimet (TFP), which is a PFAS chemical according to the definition of the Organisation for Economic Co-operation and Development (OECD). The fact that the chemical is not registered by EPA means that it has not been reviewed in accordance with all the safety assessments reviewed under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). The states applying for the exemptions under Section 18 of FIFRA—Missouri and Arkansas—claim that there is an emergency requiring the use of TFP because […]

North American Birds’ Decline Associated with Agriculture

(Beyond Pesticides, March 6, 2026) Does humanity want to live in a world without birds? This may seem like an extreme question, but a new study in Science concludes that, without changes in human behavior, just such a world may be on the horizon. This would be a tragedy of colossal proportions, not only for the ecosystem services birds provide, but for the meaning of human life and a healthy biosphere. The oldest human-made image of a bird is 40,000 years old. The new study, by Czech environmental scientist François Leroy, PhD, and two colleagues from The Ohio State University, measured local population abundances of 261 North American bird species between 1987 and 2021. They also measured the speeds at which the species’ populations rose or fell. The study was based on data from the North American Breeding Bird Survey, a program of the U.S. Geological Survey in coordination with the Canadian Wildlife Service. This survey involves direct observations of bird populations along roadsides during breeding season. The program was created in the mid-20th century in response to the severe mortalities associated with the use of DDT, highlighted by Rachel Carson in her seminal 1962 work, Silent Spring. In the […]

USRTK Spotlights Bayer-Monsanto Ties to Trump Administration, as Company Pushes for Immunity from Lawsuits

(Beyond Pesticides, March 5, 2026) In a deep analysis of public records, U.S. Right to Know (USRTK), a nonprofit newsroom and public health research group, discloses significant financial ties between Bayer-Monsanto, lobbying firms, and the second Trump Administration, raising concerns about basic safeguards to curb corporate influence over federal policymakers. The USRTK tracker and report, “Tracing Bayer’s ties to power in Trump’s Washington,” (see more) finds that there have been significant lobbying investments by the multinational pesticide corporation just in the past year, including:  “At least $9.19 million on federal lobbying in [2025]”;   “16 key administration officials with ties to Bayer’s lobbying or legal network. Bayer and its lobbyists have access to people in power at the White House, U.S. Department of Agriculture, the Environmental Protection Agency and even those in high level positions closest to Trump”;  “45 people registered to lobby for Bayer under the Lobbying Disclosure Act, and at least 13 outside lobby firms – seven of which are now among the highest-paid firms in D.C”; and,  “More than 30 senior officials at lobby firms retained by Bayer have direct ties to Trump, having worked in one or both of his administrations or political campaigns.”  The report points out that the four main trade and […]

Studies Find Genetic and Epigenetic Effects from Pesticide Exposure, Threatening Future Generations

(Beyond Pesticides, March 3, 2026) Research published in Critical Reviews in Toxicology (CRT) and Proceedings of the National Academy of Sciences (PNAS) documents the genetic and epigenetic (changes to gene function without altering the DNA sequence) effects to pesticide-exposed groups through early-life exposure and from transgenerational inheritance (passed down through generations). These studies highlight the complex nature of mechanisms of toxicity, as well as the various pesticide exposure routes that begin even prior to conception. The analyses evaluate general and specific pesticide exposure as reported in observational and laboratory research. Through a systematic review and meta-analysis of studies on “DNA damage, cytogenetic damage, DNA methylation, or gene expression outcomes associated with prenatal and early childhood pesticide exposure,” the CRT authors link genotoxic mechanisms and epigenetic alterations to adverse health outcomes while the PNAS study shows pesticide-induced epigenetic alterations in mammals across 20 generations that “suggest the maternal and paternal lineages can both induce and inherit epigenetic alterations that influence disease (e.g., kidney, testis, ovary, prostate) incidence, reproductive health (e.g., parturition, infertility), and overall fitness generationally.” As the CRT study states: “One of the main ways pesticides can cause harm is through genotoxicity—their ability to damage genetic material. This damage can […]

Women in Agriculture at Elevated Risk of More Aggressive Breast Cancer from Pesticides, Study Finds

(Beyond Pesticides, February 26, 2026) Published in PLOS ONE, research in Brazil “analyzed the impact of occupational/household chronic exposure to pesticides on the clinicopathological profile of breast cancer in rural women from Paraná southwest, a predominantly rural landscape with large pesticide uses,” finding that “pesticide exposure favors the occurrence of more aggressive breast cancer.” The study highlights the disproportionate risks of pesticides to farmworkers, focusing on women, as it compares exposed and unexposed populations and breast cancer tumor/disease characteristics. One of the study authors, Carolina Panis, PhD, discussed her earlier research at the Beyond Pesticides’ 42nd National Forum Series, The Pesticide Threat to Environmental Health: Advancing Holistic Solutions Aligned with Nature. In her previous work, Pesticide exposure and increased breast cancer risk in women population studies, Dr. Panis documents a number of pesticides that “can increase the risk of BC [breast cancer] development through various mutagenic [genetic mutations] and nonmutagenic mechanisms and can act directly as carcinogens or indirectly as biochemical modifiers and hormonal deregulators. The underlying mechanisms include endocrine disruption; genotoxicity; epigenetic changes [changes to gene function without changing DNA]; enhanced cell migration, invasion, and…” more. Dr. Panis and other researchers at the Forum support community-level understanding of the […]

Data on Weed Killer Glyphosate in Food Released, Then President Declares Its Use Is in the National Defense

(Beyond Pesticides, February 25, 2026) Residues of the weed killer glyphosate, which has been classified as “probably carcinogenic to humans” by the International Agency for Research on Cancer, have been routinely found in food products, and a recent state survey in Florida confirmed previous findings. The findings are well within the legal standards for allowable residues. So, why is the Trump administration, in invoking the Defense Production Act of 1950 by Executive Order and its immunity-from-lawsuits provision for glyphosate manufacturers, concerned about glyphosate residues in food and other nondietary exposure? Could it have something to do with the over $10 billion in jury verdicts and settlements on glyphosate exposure against the manufacturer Bayer/Monsanto, with tens of thousands of cases pending, and the robust independent, peer-reviewed scientific findings that link glyphosate to non-Hodgkin lymphoma and a host of other adverse health effects? Nothing in the President’s executive order appears to meet the intent of the statute and its stated purpose to protect “the ability of the domestic industrial base to supply materials and services for the national defense and to prepare for and respond to military conflicts, natural or man-caused disasters, or acts of terrorism within the United States . . .” Without […]

Dietary Exposure of Poultry to Common Pesticide Mixtures Threatens Reproductive Health, Study Finds

(Beyond Pesticides, February 18, 2026) Research finds that widespread agricultural pesticide use increases chronic dietary exposure in poultry and leads to adverse reproductive effects, despite meeting legal residue limits. As published in Poultry Science by researchers in Poland, the study analyzes low-dose exposure of roosters (Gallus gallus domesticus) to the fungicide tebuconazole (TEB), the insecticide imidacloprid (IMI), and the weed killer glyphosate (GLP) individually and in mixtures, with all concentrations at or below the maximum residue limits (MRLs) established by the European Union (EU). “Sub-MRL pesticide exposure impaired male reproductive function, with the most pronounced effects observed following combined treatments,” the authors report. They continue: “[E]xposure resulted in reduced semen quality, decreased fertility and hatchability, and increased embryo mortality, particularly in groups receiving IMI alone or in combination. These functional impairments were accompanied by detectable pesticide residues in reproductive tissues and body fluids, as well as modulation [modification/alteration] of local and systemic immune parameters.” The results of the experiment highlight how combined pesticide exposure, resulting from common use of multiple pesticide active ingredients concurrently, produces “stronger and more persistent reproductive effects than individual compounds, indicating mixture-specific toxicity.” This study is particularly important, as it represents the chronic exposure to MRL-compliant […]

Study Identifies Pesticide Residues in Soil as a Main Driver of Adverse Effects to Soil Biodiversity

(Beyond Pesticides, February 13, 2026) In a novel, continent-wide study of soil biodiversity throughout Europe published in Nature, researchers find 70% of the sampled sites contain pesticide residues, which “emerged as the second strongest driver of soil biodiversity patterns after soil properties,” particularly in croplands. As soil biodiversity is key for ecosystem functioning, agricultural and land management practices that safeguard biodiversity are imperative. This study, however, highlights how pesticides alter microbial functions, including phosphorus and nitrogen cycling, and suppress beneficial taxa, such as arbuscular mycorrhizal fungi and bacterivore nematodes, and adds to a wide body of science that links pesticide residues in soil to adverse effects on biodiversity. In analyzing 373 sites across woodlands, grasslands, and croplands in 26 European countries, and examining the effects of 63 pesticides on soil archaea, bacteria, fungi, protists, nematodes, arthropods, and key functional gene groups, the data reveals “organism- and function-specific patterns, emphasizing complex and widespread non-target effects on soil biodiversity.” As the authors state, “[T]o our knowledge, ours is the first study to demonstrate the relative importance of pesticides in comparison to soil properties, ecosystem type and climate at a continental scale.” Study Importance As Kristin Ohlson describes in her book The Soil […]

As Litigation and Settlements Mount for the Weed Killer Paraquat, Advocates Call for a Ban and Alternatives

(Beyond Pesticides, February 11, 2026) The first U.S. jury trial on the weed killer paraquat against global chemical companies Syngenta Crop Protection, Chevron U.S.A., FMC Corporation, and their predecessors was scuttled last month due to a settlement on the eve of the case being heard in court. Settlements are commonly used by pesticide manufacturers seeking to avoid public disclosure of internal documents on chemical hazards and wrongdoing that could result from a public trial. In Mertens et al. v. Syngenta, Chevron, and FMC, the six plaintiffs suing three corporations allege that exposure to paraquat-based herbicide products contributed to their Parkinson’s Disease diagnosis. While the terms of the settlement have not yet been disclosed, Lawsuit Information Center states that the paraquat class action multidistrict litigation (MDL) includes 8,257 cases as of January 16, 2026. In 2021, multiple cases were settled for more than $187 million. Background on Mertens Complaint In their complaint, the plaintiffs point to five causes of action, including “strict products liability design defect” (Count 1), “strict products liability failure to warn” (Count 2), negligence (Count 3), breach of implied warranty of merchantability (Count 4), and punitive damages (Count 5).

U.S. Abandons International Collaboration on Existential Health Challenges at Time When Most Needed

(Beyond Pesticides, February 6, 2026) The United States, under Donald Trump’s direction, has withdrawn from 66 international organizations, the most important for health being the United Nations’ World Health Organization (WHO) and the Intergovernmental Panel on Climate Change. International organizations committed to the application of the best available science and policy development via consultation and consensus serve as a vital check against rampant personal and industry nest-feathering at the expense of global health. The Trump administration has removed this check while expanding his and his associates’ self-dealing and dismissing the critical interactions of crises such as climate change and synthetic chemicals. Although Trump announced this move on inauguration day last year, the completion of the process last week puts the stamp of finality on his total abandonment of public health. This in turn threatens the collapse of WHO—and even the U.N.—altogether, which has wide implications for agriculture, particularly pesticide policies, climate action (and inaction), and infectious disease monitoring, including vaccines and pandemic prevention. [See commentary: On Public and Environmental Health and Worldwide Collaboration.] Other U.N. environmental, health, and agricultural organizations on the list are groups focused on forest degradation, freshwater and oceans, mining, minerals, metals, and sustainable development, biodiversity, and ecosystem […]

Amid Immediate and Chronic Health and Environmental Effects, Drift-Prone Herbicide Slated for Reapproval

[Update on February 9, 2026: In a press release on Friday, February 6, titled “EPA Implements Strongest Protections in Agency History for Over-the-Top Dicamba Use on Cotton and Soybeans for Next Two Growing Seasons,” the U.S. Environmental Protection Agency (EPA) continues to ignore the wide body of science that documents harms from dicamba, as well as the viability of alternative methods, in establishing what the agency is boasting are “the strongest protections in agency history for over-the-top (OTT) dicamba application on dicamba-tolerant cotton and soybean crops” as a direct response to the “strong advocacy of America’s cotton and soybean farmers.” These so-called “strong protections” are described as a way to ensure farmers can access the tools they “need” while also protecting the environment from dicamba’s harmful drift. In using “gold-standard science and radical transparency,” EPA created new label restrictions for the next two growing seasons that include “cutting the amount of dicamba that can be used annually in half, doubling required safety agents, requiring conservation practices to protect endangered species, and restricting applications during high temperatures when exposure and volatility risks increase.” Relying on unenforceable label restrictions and mitigation measures, however, fails to adequately protect health and the environment.

Data from Agricultural Health Study Associate Diabetes with Pesticide Exposure

(Beyond Pesticides, February 4, 2026) Using data from the Agricultural Health Study (AHS) database launched in 1993 by the National Cancer Institute and the National Institute of Environmental Health Sciences, research study results “show greater diabetes risk“ from exposure to organochlorine, organophosphate, and carbamate insecticides, phenoxy and other herbicides, and the fumigant carbon tetrachloride/disulfide exposure. The study, published in Environment International, evaluated nearly 4,000 diabetes cases drawn from AHS follow-up surveys between 1999 and 2021. Results Researchers found evidence of an association between 18 pesticide active ingredients and diabetes. These included two phenoxy herbicides, 2,4,5-T and 2,4,5-TP, and seven organochlorine insecticides (DDT, aldrin, dieldrin, chlordane, heptachlor, toxaphene, and lindane). While all these organochlorine pesticides are banned for use in the U.S. (with the exception of pharmaceutical uses of lindane), legacy residues of the chemicals and/or their metabolites continue show up in the environment, food, and the human body, and 2,4,5-T and its TCDD dioxin contaminant has multigenerational effects. There was exposure risks among other pesticides were identified as well, including: 3 organophosphate insecticides (diazinon, malathion, and phorate); 2 carbamate insecticides (carbofuran and carbaryl); 3 other herbicides (butylate, metribuzin, and chlorimuron ethyl); and the fumigant carbon tetrachloride/disulfide.

Pesticide Contamination in Small Water Bodies Threatens Biodiversity and Ecosystem Functioning, Study Finds

(Beyond Pesticides, February 3, 2026) In analyzing the direct and indirect effects of pesticides that act simultaneously upon macrozoobenthos communities (invertebrates living in or on sediment) in standing small water bodies (SWBs) in Germany, researchers find high risks to biodiversity and ecosystem functioning. Published in Hydrobiologia, the experiment finds high risks to invertebrates and highlights how both direct and indirect effects are vital to comprehensive assessments of pesticides. While typically overlooked in regulatory reviews, SWBs are defined as shallow standing or running freshwaters “with a surface area of less than 50 hectares (ha),” such as lakes or ponds, including farm ponds, as well as headwater streams, springs and flushes, and ditches. SWBs are biodiversity hotspots that contribute to numerous ecosystem services and are adversely affected by agricultural land use effects such as pesticide contamination. “Holistic assessments of pesticide effects on invertebrate communities in standing small water bodies have, however, not yet been successful,” the authors note. To address this, the researchers developed an indicator for evaluating pesticide impacts on macrozoobenthos communities, populated with aquatic invertebrates, such as snails, worms, crayfish, and clams, through indirect toxic effects on aquatic plants called INPOND: INdirect Pesticide impacts ON Diversity in standing small water […]

Neonicotinoid Insecticides Cause Deadly Overheating Behavior in Honey Bees, Study Finds

(Beyond Pesticides, January 29, 2026) A study of ecotoxicity risk from neonicotinoid insecticides, published in Environmental Chemistry and Ecotoxicology, finds that chemicals in this class of pesticides, particularly dinotefuron, increase the body temperature of Apis mellifera (European honey bee) and subsequently accelerate the translocation (movement) of contaminants into hives by the honey bees. The research indicates that neonicotinoids affect acetylcholine receptors in the nervous system, leading to an “elevation in octopamine titer [neurotransmitter/hormone] and subsequent increase in the body temperature of honeybees,” the authors report. They continue: “Furthermore, we observed a considerable upregulation [of] the expression of a flight gene flightin in honeybees. This gene accelerates the homing behavior of honeybees and facilitates the rapid and frequent transport of neonicotinoid pesticide-contaminated nectar to the hive.” In describing their results, the researchers state: “For the first time, we propose that neonicotinoid pesticides accelerate the homing ability of honeybees by affecting their body temperature, which leads to more neonicotinoid pesticides entering the hive and explains the prevalence of neonicotinoids and at higher concentrations in terms of their effects on the honeybee body temperature that enhances homing.” This accelerated movement of neonicotinoid pesticides into honey bee hives heightens the toxicity risks to honey […]

Pervasive Pesticide Contamination of Beehives Across Europe, the First EU-Wide Study of Its Kind

(Beyond Pesticides, January 28, 2026) A study published last year in Science of The Total Environment reports widespread pesticide contamination collected from beehive monitoring across the European Union (EU). “This study has produced the first EU-wide distribution map of terrestrial pesticide contamination and demonstrates widespread pesticide contamination of EU environments,” the authors write. The study, led by a cohort of citizen-scientists, documents pesticide drift across the European continent. The results found that 188 of the 429 targeted pesticide compounds were detected in noninvasive, in-hive passive samplers (APIStrips) across 27 EU countries between May and August of 2023. This finding emerges at a time when public health and environmental advocates raise concerns about the European Union’s backtracking on commitments to reduce pesticide use by 2030, although the European Commission announced in July 2025 that “the use and risk of chemical pesticides has decreased by 58% by 2023 [from the 2015-2017 reference period], while the use of more hazardous pesticides fell by 27% over the same period.” Results The study results reveal that no landscape is safe from pesticide exposure, despite the European Union having better regulations in place than most other countries/regions. The researchers found: “There was no sample site where […]

Widely Used Insecticide in Food Production Triggers Neurological Effects Linked to Parkinson’s Disease

(Beyond Pesticides, January 27, 2026) A three-part study published in Molecular Neurodegeneration draws a connection between Parkinson’s disease (PD) and the organophosphate chlorpyrifos. “Since chlorpyrifos (CPF) exposure has been implicated as a risk factor for PD, we investigated its association to incident PD and if this association is biologically plausible using human, rodent, and zebrafish (ZF) studies,” the researchers state. Together, the three experiments “strongly implicate exposure to CPF as a risk factor for developing PD,” as the authors find that exposure, even at very low concentrations, causes selective toxicity to dopaminergic neurons that are critical for functions of movement, cognition, emotion, and more. The results reveal that in humans, long-term residential exposure is associated with more than a 2.5-fold increased risk of developing PD, while exposure in mice causes “motor impairment, dopaminergic neuron loss, microglial activation, and an increase in pathological α-synuclein (α-syn) [proteins primarily found in the brain].” The researchers continue, “Using ZF, we found that CPF-induced dopaminergic neuron loss was at least partially due to autophagy dysfunction and synuclein accumulation, as knocking down LC3 [a protein chain] recapitulated the dopaminergic neuron loss.” These three studies highlight the association of CPF with increased risks for developing PD, as […]

Chronic Low-Dose Exposure to Insecticide Chlorpyrifos Reduces Wild Fish Lifespan by Accelerating Aging

(Beyond Pesticides, January 23, 2026) A fish called a lake skygazer (Culter dabryi) shows accelerated aging when exposed to chronic low doses of the insecticide chlorpyrifos, according to a powerful study by researchers from several Chinese institutions, as well as Carleton University in Canada and the University of Notre Dame in Indiana. The study, in Science, finds that chronic low-dose exposures resulting in the accumulation of sublethal effects over time cause deterioration of molecular, cellular, and organ functions that reduce lifespan and fertility. In the study, the fish showed reduced survival in a “dose- and physiological age-dependent manner,” while acute high doses did not have these effects, the authors write. Because the mechanisms researchers focused on are conserved throughout vertebrates, “even low doses of pesticide may pose long-term risks to longevity” in thousands of species, including humans. The regulation of pesticides is based on laboratory animals’ exposure to acute high doses of a chemical–generally measured as the dose that kills half the test animals within 96 hours of exposure. Thus, the assumption that guides the calibration of “safe” or allowable levels of exposure is that lower doses, even if chronic, pose no threat. The current study unambiguously refutes that assumption, […]

Review Finds Reproductive Toxicity from Neonicotinoid Insecticides, Highlighting Widespread Hazard

(Beyond Pesticides, January 22, 2026) Published in Environmental Research, a review of experimental studies by George Mason University researchers regarding reproductive toxicity of neonicotinoid pesticides (neonics) in rodents finds that all studies “demonstrated negative impacts on male reproductive endpoints in association with neonic exposure, including reduced sperm count, reduced sperm motility, and altered sperm morphology.” These studies highlight how neonics, designed to target insect nervous systems, can affect mammalian systems, representing risks to human health. Criteria for inclusion in the review was restricted to endocrine and/or reproductive outcomes in male rats and mice, leading the authors to analyze 21 studies published between 2005 and 2025. “This narrative review employed a systematic approach and determined that neonics exhibit reproductive toxicity in male rats and mice, particularly impairing testicular function and sperm quality at high exposure levels,” the researchers report. They continue, “Despite species-specific differences, the conserved nature [core mechanism] of reproductive processes across mammals supports the relevance of these findings to human health.” Study Background Neonicotinoids are a class of insecticides that share a common mode of action that affects the central nervous system of insects, resulting in paralysis and death. There is a wide body of science on the effects […]

USDA Monitoring Report Declares Pesticide Residues in Food Supply Safe, Despite Science to the Contrary

(Beyond Pesticides, January 21, 2026) The data in the annual U.S. Department of Agriculture (USDA) pesticide residue report, released earlier this month, continues to show a pattern of pesticide residues in the majority of food tested by the U.S. Department of Agriculture (USDA). Health advocates say low-level pesticide residues in the food supply within legal limits raise serious hazard concerns, while USDA, in its Pesticide Data Program–Annual Summary, Calendar Year 2024, points to controversial residue standards as a measure of safety. The USDA report finds that over 57 percent of tested commodities contain at least one pesticide and that less than one percent of detected residues violate the legal limit set as a tolerance by the U.S. Environmental Protection Agency (EPA). Residues allowed under tolerances establish allowable pesticide use patterns in agriculture that, beyond dietary risks, result in exposure to farmworkers, farmers, waterways, wildlife, and the broad ecosystem in which they are used. (See Eating with a Conscience for a list of pesticides allowed in food production by commodity.) With respect to the preponderance of evidence on adverse health and ecological effects of cumulative exposure to toxic agrichemicals, including pesticides, Beyond Pesticides has called for the transition to organic agriculture.

Protection from Elevated Chemical Hazards Before High Court, Converges with Adverse Effects of Deregulation

(Beyond Pesticides, January 20, 2026) With Monday’s celebration and affirmation of Martin Luther King Jr.’s life and legacy, the question of adequate protection of the people and communities at greatest risk from toxic chemical production, transportation, use, and disposal looms large. This is especially true with the current diminished federal regulatory authority and Bayer/Monsanto’s U.S. Supreme Court challenge of chemical manufacturers’ responsibility to warn users of their products of hazards like cancer. Actions Being Taken In response to the chemical industry campaign to deny people the right to sue under longstanding failure to warn law, groups are calling for public support of U.S Senator Cory Booker’s (D-NJ) bill, Pesticide Injury Accountability Act(S. 2324) seeks to uphold this right  to sue. The groups are calling on 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.  In an additional action in honor of Martin Luther King, Jr., Beyond Pesticides is calling on the public to “Tell members of Congress to ensure that with the termination of environmental justice programs at EPA, they […]
