(Beyond Pesticides, June 30, 2026) A peer-reviewed article, published in Scientific Reports, focuses on the link between exposure to pesticide mixtures and Alzheimer’s Disease (AD) prevalence at the county-level across the United States. Alzheimer’s, a type of dementia that affects memory, thinking, and behavior, accounts for 60-80% of dementia cases. In conducting a novel cross-sectional analysis of data on pesticide application intensity and disease prevalence, the researchers, from the Medical University of South Carolina, are able to identify exposure clusters with significant associations to the occurrence of AD. The strongest positive associations, where AD prevalence increases as pesticide exposure increases, are “observed for a soil fumigation/nematicide system, an herbicide-dominant vegetation control regime, and a neuroactive insecticide system,” the authors note. These findings link pesticide mixtures to increased AD rates. (See the full PDF of the study here.) Study Importance and Background AD is a condition that gradually damages and destroys neurons in the brain, with disproportionate risks across the U.S. in certain geographical areas. (See here and here.) “These spatial patterns suggest that contextual and environmental determinants may contribute to disparities in dementia burden beyond established individual-level risk factors,” the researchers state. They continue, “Although AD dementia is the leading […]

(Beyond Pesticides, June 12, 2026) In a literature review published in Caspian Journal of Environmental Sciences, researchers assessed 27 peer-reviewed studies conducted between 2011 and 2025 on the adverse impacts of insecticides, including neonicotinoids, pyrethroids, organophosphates, chlorpyrifos, and fipronil. Across agricultural and suburban environments, pesticides were detected in the majority (88 percent) of samples. This review builds on the continuous flow of science that highlights the adverse impacts of synthetic pesticide dependency on ecosystems and wildlife that are essential to global biodiversity. Main Findings The researchers, based at a variety of research institutions in Jordan, Uzbekistan, Iraq, and India, refined their search to 27 studies after screening for geographic diversity and empirical robustness; for example, they excluded studies that did not include empirical data, relied solely on nonagricultural contexts, or only assessed exposure through urban wastewater exclusively. Toxicological data assessed include pesticide occurrence, toxicity, and biological responses. This literature review is not a meta-analysis, but rather a narrative synthesis of various findings. The main findings include: Documented Widespread Pesticide Occurrence. In the United States, based on data collected between 2013 and 2017, 88 percent of water samples contained pesticides, with a median of 18 compounds across all sites and 24 […]

(Beyond Pesticides, May 11, 2026) As studies stack up on adverse synergistic effects of chemical mixtures, serious deficiencies in the regulatory review of pesticides have come into sharp focus. As the hazards are shown to escalate and the regulatory review process is shown to fall short, public health advocates are telling Congress, the U.S. Environmental Protection Agency, and the Department of Health and Human Services that they must consider the effects of pesticides in the context in which they are used and with reference to the organic alternative.  A recent study in Toxics reviewed the current literature on pesticides, microplastics, or metal exposure in combination with per- and polyfluoroalkyl substances (PFAS) on aquatic vertebrates and invertebrates, finding that PFAS can modify, including intensify, the toxicity of co-occurring pollutants.   A commentary in Frontiers in Toxicology, by  Maricel Maffini, PhD, and Laura Vandenberg, PhD,  notes, “Current approaches also rely on the assumption that testing chemicals one at a time is appropriate to understand how chemicals act under real-world conditions. Numerous mixture studies, including ones that demonstrated cumulative effects, have disproven this assumption.”   As noted by the naturalist, writer, and conservationist John Muir, known as the “Father of the National Parks,” and those before and after him, including the English poet John Donne, […]

(Beyond Pesticides, April 28, 2026) In Chemical Research in Toxicology, researchers from the Universitat Rovira i Virgili in Catalonia, Spain highlight the threats to human and environmental health with “combined exposures to multiple chemical toxicants, including industrial chemicals, heavy metals, pesticides, endocrine-disrupting chemicals (EDCs), and per- and polyfluoroalkyl substances (PFAS).” As these compounds are encountered in mixtures in real-world settings, the resulting interaction can have additive or synergistic effects that risk assessments fail to adequately capture. As the authors point out: “This leads to a systematic underestimation of health risks, particularly for vulnerable populations. Despite robust evidence on mixture toxicity, major regulatory frameworks such as the U.S. Toxic Substances Control Act (TSCA) and the EU’s [European Union] REACH program continue to assess chemicals in isolation.” Importance and Background Environmental toxicants are ubiquitous throughout nature and within all organisms. In humans, these compounds can accumulate, referred to as ‘Body Burden’, which encompasses numerous chemicals such as pesticide mixtures. “Critically, organisms are rarely exposed to a single chemical in isolation,” the researchers note. “Rather, they continuously encounter complex mixtures of contaminants whose combined effects may differ substantially from those predicted by examining each substance individually.” As the authors explain, regulatory agencies underestimate […]

Riparian zones, recognized as biodiversity hotspots, “are increasingly subjected to various stressors, including chemical contaminants such as pesticides,” the authors state. As transportation of these compounds can occur not only through surface runoff but through flooding events, the frequency and duration of floods can greatly impact the cumulative effects of pesticides on soil health and organisms within ecosystems. In analyzing pesticide residues following simulated flooding within a controlled experiment, the researchers find: “[S]ix pesticides were detected exclusively in riparian root-zone soil following four repeated flooding events. Our findings indicate that both longer flood durations and repeated flooding events tend to increase […]

(Beyond Pesticides, April 15, 2026) Researchers in the Czech Republic tested indoor dust across 116 homes and found that 93 percent of homes across urban and rural areas contained residue of at least one current-use pesticide (CUP). The study also found in every household residues of hexachlorobenzene (HCB) and pentachlorobenzene (PeCB), the breakdown products or byproducts of certain banned organochlorine pesticides (OCP). These compounds, as well as DDT metabolites DDE and DDD, were detected in more than half of the homes tested. Results in this study and previous research confirm that pesticides used outdoors find their way indoors, resulting in an exposure pattern that is not calculated when pesticides are registered and allowed on the market. The findings are published in Indoor Environments. These findings characterize the legacy of toxic pesticide exposure resulting from the proliferation of pesticides in the United States and around the world without a complete assessment of the chemicals’ residual activity and multigenerational adverse impacts on health. Based on the decades of peer-reviewed scientific literature on pesticide exposure and effects from across the globe, public health and environmental advocates warn that there is a continuation of this pattern of long-term effects associated with new pesticides linked […]

(Beyond Pesticides, April 14, 2026) A novel study mapping pesticide mixtures and cancer risk, published in Nature Health, “reveals a robust spatial association between environmental pesticide exposure risk and cancer incidence.” The team of international researchers incorporates pesticide risk modeling with Peruvian National Cancer Institute (INEN) registry data to map pesticide-induced cancer clusters in Peru, finding significant associations between pesticide mixtures and cases of carcinogenicity. The study analyzes 31 active ingredients to identify pesticide-associated cancer hotspots, none of which are classified as carcinogenic on their own by international standards. When combined as pesticide mixtures, as experienced in real-world environments, heightened risks and synergistic effects are noted. “Collectively, these findings strongly support a mechanistic [causal] link between pesticide exposure and cancer, challenging assumptions of human non-carcinogenicity derived from reductionist experimental models,” the authors state. “This study redefines the exposome [measure of all environmental, dietary, lifestyle, and social exposures of an individual] as a lineage-conditioned, mechanistically tractable framework and shows how complex pesticide mixtures can contribute to carcinogenic trajectories, with profound and far-reaching implications for global health policy and socio-ecological equity.” Background An extensive body of scientific literature connects individual pesticide active ingredients to a wide array of health and environmental effects […]

(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 […]

(Beyond Pesticides, February 12, 2026) Editor’s Note. This is a piece about improving risk assessments and a proposal that could offer a more realistic characterization of the harm associated with the complexities of pesticide exposure. Beyond Pesticides notes that risk assessment methodology, unless it is considered in the context of a rigorous alternatives assessment, begins with the mostly false assumption that petrochemical pesticides are needed (or are essential) to achieve cost-effective pest management, agricultural productivity and profitability, and quality of life, when, in fact, this is not the case. Therefore, improved risk calculations—as the article being reviewed here proposes—while important to characterizing the harm and the unknown adverse effects associated with pesticide use, still impose some level of harm deemed by the government to be acceptable. Even worse, the adverse effects of exposure cannot be fully characterized because of uncertainties or a lack of data on harmful endpoints, as is the case currently with endocrine-disrupting pesticides not fully evaluated by the U.S. Environmental Protection Agency (EPA), California’s Department of Pesticide Regulation (DPR), or other regulatory bodies. These pesticides are known to induce cancer, reproductive harm, infertility, biodiversity decline, and other life-threatening, often multigenerational, effects. The authors do recognize the serious […]

(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. […]

(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, November 7, 2025) There is little dispute that modern industrial culture has produced a constellation of related chronic conditions contributing powerfully to human disease. In recent decades, attention has begun to focus on the developmental origins of health and disease—prenatal exposures to pesticides, for example, that contribute to diseases in adulthood, such as cardiovascular and metabolic problems, along with the combination, known as cardiometabolic syndrome. Cardiometabolic disorders include obesity, hypertension, cholesterol imbalances, and insulin resistance. The usual suspects blamed for the syndrome are poor diet, physical inactivity, and genetic predisposition. These are all well-established risk factors, but they fail to fully account for the sharp rise in cardiometabolic syndrome globally. Obesity prevalence has doubled and diabetes quadrupled over the last 40 years, according to the Non-Communicable Diseases (NCD) Risk Factor Collaboration. In a study on early life exposure to a pesticide mixture, researchers analyze sex differences in cardiometabolic outcomes from prenatal and early life. The study was conducted by an international team of scientists led by Ana M. Mora, M.D., of the Center for Environmental Research and Community Health at the University of California, Berkeley, using data from the Center for the Health Assessment of Mothers and Children of […]

(Beyond Pesticides, October 21, 2025) A study, published in International Journal of Hygiene and Environmental Health, calculates cumulative dietary pesticide exposure and finds a significant positive association between pesticide residues in food and urine when analyzing over 40 produce types. The research uses data for 1,837 individuals from the 2015–2016 National Health and Nutrition Examination Survey (NHANES) and compares them to biomonitoring samples of the participants. According to the researchers, “Here we show that consumption of fruits and vegetables, weighted by pesticide load, is associated with increasing levels of urinary pesticide biomarkers.” They continue, “When excluding potatoes, consumption of fruits and vegetables weighted by pesticide contamination was associated with higher levels of urinary pesticide biomarkers for organophosphate, pyrethroid, and neonicotinoid insecticides.” The NHANES data is derived from a national biomonitoring survey from the U.S. Centers for Disease Control and Prevention (CDC), which collects information about consumption of fruits and vegetables as well as urine samples. Background As the study authors explain: “Hundreds of millions of pounds of synthetic pesticide active ingredients are used every year in the United States, and pesticide exposure can occur through food, drinking water, residential proximity to agricultural spraying, household pesticide use, and occupational use. Pesticide […]

(Beyond Pesticides, October 7, 2025) Published in Environment International, a study utilizing silicone wristbands provides a snapshot of chemical exposure in over 600 participants across 10 European countries. Using the wristbands as passive and noninvasive samplers, the researchers find that organic farmers’ wristbands contain lower pesticide levels than other groups, offering insight into the benefits of organic and disproportionate risks to farmers using chemical-intensive methods. The results further reveal prevalent environmental pesticide mixtures, in addition to highlighting exposure to current-use pesticides (CUPs) and legacy (banned) pesticides that occurs through multiple exposure routes to workers, residents, and consumers. “Our study offers a comprehensive analysis of non-dietary pesticide exposure patterns among various populations across the EU [European Union], underscoring its widespread prevalence and identifying significant occupational and residential predictors,” the authors explain. As pesticide exposure occurs through both dietary and nondietary routes, such as through dermal (skin) contact and inhalation of contaminated air, there “is a growing need for aggregated [total; combined] exposure estimates across occupationally and nonoccupationally exposed populations.” The study includes testing for 193 pesticides, both legacy pesticides and CUPs, captured in silicone wristbands worn by farmers, residents living close to treated fields (neighbors), and the general population (consumers) 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 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, August 19, 2025) A new study from Argentina highlights the importance of applying the concept of the exposome (total exposures over lifetime) as a scientific framework, the value of biomonitoring, and findings of adverse pregnancy outcomes. The study documents the presence and effects of pesticides on maternal and fetal health during pregnancy. The results show that pregnant Argentine women are exposed to dozens of pesticides, and that certain mixtures of these chemicals are associated with harm to pregnancy outcomes, especially among rural women. The exposome, the authors write, comprises the “non-genetic factors that may be involved in the development or aggravation of human disease. The prenatal exposome includes all environmental chemicals that the mother is exposed to during pregnancy (maternal exposome) and those chemicals that reach the placenta and fetus from the maternal circulation (fetal exposome).” The authors emphasize that understanding the exposome almost by definition requires studying mixtures of environmental chemicals rather than analyzing the effects of each in isolation. The second important aspect of the study is its use of biomonitoring. The researchers analyzed urine samples from 90 pregnant women in various gestational stages from rural and urban regions of Argentina. The researchers also collected demographic […]

(Beyond Pesticides, June 6, 2025) Published in Environmental Pollution, a study of commercial dry pet products finds dietary pesticide residues in dog and cat food, “highlighting the urgent need for improved regulatory frameworks to address the presence of non-approved pesticides in pet food.” Additionally, the researchers point out: “Current regulatory frameworks primarily assess the toxicity of individual pesticide compounds, yet real-world exposure involves complex mixtures that may lead to additive or synergistic effects. The presence of multiple residues in a single sample suggests that companion animals may be subjected to combined toxicological burdens that are not yet fully understood.” (See studies here, here, and here.) The researchers assess pesticide contamination, and their associated toxicological risks, in 83 total food products for dogs (43) and cats (40). Of the foods tested, the researchers found a total of 51 pesticides, many of which are banned in the European Union (EU), including 47% fungicides and 37% insecticides. “Pesticide residues in pet food pose potential risks to animal health, yet their occurrence and dietary exposure in companion animals remain largely unexplored,” the authors state. They continue: “To our knowledge, this is one of the first comprehensive investigations assessing both pesticide prevalence and potential dietary […]

(Beyond Pesticides, May 13, 2025) A study in Environmental Pollution examines ecological and health risks in farmland soil with pesticide contamination. “Although agricultural soil pesticide residues have long threatened the environment, a relatively complete system for evaluating their health and ecological risks has not yet been developed,” the authors state. In addressing this research gap, the study finds that “more than ten pesticides were detected in 98.62% of the soil samples, which changed the soil environment” and threatens the health of the soil microbiome. The authors continue, “This study investigated the correlation between pesticide residue risks and soil ecological security and human health, revealed the response characteristics of soil microbial communities under pesticide stress, and identified microbes strongly related to pesticide ecological risks.” Pesticides, as the authors emphasize, “inevitably pollute agricultural soil, affect the ecological environment, and pose a threat to human health.” (See studies here, here, and here.) With this in mind, they assess 50 selected pesticides in 145 soil samples from agricultural land in Zhejiang Province, China and calculate the associated risks to ecosystems and public health. In describing the importance of this research, the authors explain: “Pesticides are prone to leakage and drift in environmental media, turning […]

(Beyond Pesticides, April 29, 2025) A study in Environment International finds pesticide-induced alterations in the gut microbiota of a farmland raptor species. In collecting blood and cloacal samples from Montagu’s harrier (Circus pygargus) nestlings, the authors “shed light on an overlooked collateral effect of pesticides, i.e., a general modification of gut bacterial assemblages,” which can lead to an imbalance of microorganisms (dysbiosis) and the promotion of potential pathogens, as well as negatively impact the health of birds of prey. “Additionally, our findings support the ‘One Health‘ framework, stressing the interconnectedness of wildlife, ecosystem, and human health, particularly in pesticide-affected agricultural areas,” the researchers share. “The gut microbiota is crucial for host health and can be impacted by various environmental disruptions, yet the effects of multiple pesticide exposures on farmland organisms’ microbiomes remain largely unexplored,” the authors state. In the study, they “assessed microbiota changes in a wild apex predator exposed to multiple pesticides in agricultural landscapes,” which “provides evidence of pesticide impacts on wildlife gut microbiota, highlighting links between pesticide exposure and changes in microbiota composition,” the researchers note. The Montagu’s harrier, as an apex predator, serves as a ‘bio-sentinel’ or bioindicator species for assessing ecosystem health. “As top-level predators […]

(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, March 17, 2025) When Secretary of Health and Human Services Robert F. Kennedy, Jr. announced last week that he is directing the U.S. Food and Drug Administration (FDA) to explore rulemaking to review substances in food affirmed by the food companies to be Generally Recognized as Safe (GRAS), he said he is “committed to promoting radical transparency to make sure all Americans know what is in their food.” The issue of independent review of the food industry’s GRAS declarations has long been the subject of critiques raising public health concerns. As this issue emerged, on another food safety issue, Beyond Pesticides is asking  FDA to use its broad authority under the Federal Food, Drug, and Cosmetic Act to “ensur(e) that human foods and animal feeds are safe” from residues of pesticide mixtures, in light of new troubling scientific data. Under various memoranda of understanding between FDA, the U.S. Environmental Protection Agency (EPA), and the U.S. Department of Agriculture (USDA) going back decades, FDA could consult with EPA on food safety issues ignored by the agency, including  recent data published in Pesticide Biochemistry and Physiology, which “suggest that combined [pesticide] exposure may further amplify the toxicity and compromise the intestinal […]
