(Beyond Pesticides, March 13, 2025) Study results published in Pesticide Biochemistry and Physiology “suggest that combined [pesticide] exposure may further amplify the toxicity and compromise the intestinal barrier.†The researchers studied the toxic effects of the insecticides abamectin and spirodiclofen, as well as the fungicide fluazinam, individually and in combination. In exposing mice and Caco-2 cells to these pesticides, the results show the disruption of intestinal functions and highlight the need to assess potential synergistic effects of pesticide mixtures as a part of the regulatory review process. Effects on the intestinal barriers of mice represent a threat to “the first line of defense against the external environment,†the researchers say. The intestinal mucosal epithelial structure plays an important role in preventing harmful substances from entering the intestines and causing damage to cells. [Caco-2 cells represent a human cell line, derived from a colon cancer patient’s tissue, and mimic the small intestine. These cells are vital in research as a model of the intestinal epithelial barrier.] “Currently, most studies investigating the effects of pesticide residues on the barrier function of Caco-2 cells concentrate on the exposure to a single residue, while the potential toxic effects arising from the . . .

(Beyond Pesticides, March 12, 2025) Earthjustice filed a lawsuit with the U.S. Department of Agriculture (USDA), challenging the Department’s alleged illegal purging of datasets, resources, and pertinent information that organic farmers rely on to carry out their operations, according to the complaint filed on February 24, 2025. The deletion of public data compounds the numerous threats facing organic and regenerative organic farmers across the nation. The uncertainty associated with the starting and then stopping of tariffs has led to surges in costs and supply chain challenges. Meanwhile, core organic programs, including the Organic Certification Cost Share Program, Organic Data Initiative, and Organic Certification Trade and Tracking Program, remain unfunded, leaving huge uncertainties for the organic sector moving forward. The administration has canceled the spring meeting of the National Organic Standards Board (NOSB), the Congressionally-mandated board established to guide the setting of standards and materials on the National List of Allowed and Prohibited Substances. In theory, organic farmers and public and environmental health advocates align with some of the stated objectives of the Make America Healthy Again Commission (MAHA), established by executive order on February 13, 2025. MAHA’s stated efforts to “drastically lower….chronic disease rates and . . .

(Beyond Pesticides, March 11, 2025) A study in Toxics analyzes ipconazole, a triazole fungicide often used as a coating on treated seeds and as a foliar treatment on the leaves of plants. “Triazole pesticides are widely used throughout the world, but their abuse causes toxic effects in non-targeted organisms,†the researchers state. In the current study, unintended reproductive effects are noted in male sheep (ram) and pigs (also known as porcine or swine). This research focuses on the impact of ipconazole exposure on spermatozoa (sperm) in two mammal species and finds spermiotoxicity through significantly reduced sperm viability, as well as alterations in enzyme and gene expression related to fertility. “To our knowledge, this is the first study to evaluate the cytotoxic effect of the triazole ipconazole on mammalian spermatozoa,†the authors share. This analysis utilizes semen samples from the Reproductive Biotechnology Laboratory of the Major National University of San Marcos in Lima, Peru, the university where six of the nine researchers are Faculty of Veterinary Medicine.  “The sperm were exposed to ipconazole concentrations of 1, 5, 10, 50 and 100 µM, and to a control without ipconazole,†they say. Similar concentrations have been used in . . .

(Beyond Pesticides, March 10, 2025) Following International Women’s Day, celebrated on March 8, 2025, the poignant findings on women, gender, and hazardous substances in a United Nations report raise critical issues of concern and cause for urgent action to phase out petrochemicals. The Report of the Special Rapporteur on the implications for human rights of the environmentally sound management and disposal of hazardous substances and wastes, by Marcos Orellana, was delivered to the 79th Session of the United Nations General Assembly in July 2024. Excerpts from the report follow: “Women make up roughly 60 to 70 per cent of the agricultural labour force in developing countries where pesticides and pesticide handling are especially poorly regulated. In Zambia, for example, two thirds of the labour force is engaged in agriculture, and 78 per cent are women farmers and peasants. Women there play a significant role in pesticide application, often without any or adequate personal protective equipment, especially during activities such as weeding, harvesting, and washing pesticide-laden clothes.†“In higher-income countries, women who do agricultural work are often poor and/or migrants; pesticides are one of many dimensions of marginalization and damage to their well-being.

(Beyond Pesticides, March 7, 2025) In honor of International Women’s Day on Saturday, March 8, 2025, Beyond Pesticides sheds light on the disproportionate risks to women from toxic chemicals that are often unaccounted for and even dismissed throughout pesticide regulatory review and the underlying statutes. In a roundup of Daily News coverage in 2024, as well as the most recent scientific studies in 2025, on the scientific links between pesticide exposure and adverse effects in women, this article highlights the growing inequities in pesticide threats to women’s health. Women farmers and farmworkers are particularly excluded when assessing pesticide risks. As previously reported by Beyond Pesticides, a study published in Occupational and Environmental Medicine finds that pesticide exposure, especially during puberty, can play a role in ovarian cancer development among female farmers. Although there are many studies that evaluate the risk for cancers among farmers, very few scientific articles cover the risk of ovarian cancer from pesticide exposure. Additionally, this study suggests the role of hormones in ovarian cancer prognosis and development, highlighting an association with endocrine disruption. Endocrine disruption can lead to numerous health problems in multiple organ systems, including hormone-related cancer development (e.g., thyroid, breast, . . .

(Beyond Pesticides, March 6, 2025) A proposed change to a model pesticide ordinance in the city of Portland, Maine was soundly defeated on Monday, March 3 after public engagement and a near-unanimous city council vote. In a 6-1 vote, the council rejected the school district’s request for a waiver under the city’s pesticide use ordinance to use the insecticide chlorantraniliprole/acelepryn (diamide insecticide). A campaign to reject the waiver was led by Avery Yale Kamila, cofounder of Portland Protectors, and supported by Beyond Pesticides. Portland passed a landmark Pesticide Use Ordinance in 2018 and a synthetic fertilizer ban over five years later. As stated in Beyond Pesticides testimony to the council, “Key to [the Portland ordinance’s] passage was an understanding that Portland was not going to take a product substitution approach to land management, replacing a toxic pesticide with an “organic†pesticide, but that it was facilitating the adoption of an organic systems approach that used allowed inputs (defined in the ordinance) when necessary.†The ordinance refers to allowed materials under federal organic certification law. The Landcare Advisory Committee, created by Portland’s ordinance, recommended the toxic pesticide use waiver with some objections, raising questions . . .

(Beyond Pesticides, March 5, 2025) Legislation in the state of Washington (Senate Bill 5474) is moving forward to establish a first-in-the-nation Organic Action Plan to “expand opportunities for organic, regenerative, climate-smart, and sustainable producers.†If passed, this bill would build on California’s trailblazer status as a leader in cultivating the expansion of the organic marketplace. Advocates hope that in developing the Plan, Washington will follow in the footsteps of California and European Union by setting targets for total cropland under certified organic management and bridge the gap between climate, public health, and biodiversity. As federal funding cutbacks continue to impact farmers’ ability to leverage resources and grants from the U.S. Department of Agriculture (USDA), organic and transitional farmers are eager to see states like Washington take responsibility and improve the financial viability of farmers. Mike Stranz, vice president of advocacy at National Farmers Union, spoke to Brownfield Ag News when visiting the Wisconsin Farmers Union town hall meeting on February 21 echoing these concerns, saying, “A lot of conservation and climate initiatives, a lot of local foods initiatives and programs, dollars for those were halted and cut short even as farmers and ranchers were . . .

(Beyond Pesticides, March 4, 2025) A study in GeoHealth of pediatric cancers in Nebraska links exposure to agricultural mixtures with the occurrence of these diseases. The authors find statistically significant positive associations between pesticide usage rates and children with cancer, specifically brain and central nervous system (CNS) cancers and leukemia. “Our study is the first to estimate the effect of an agrichemical mixture on the pediatric cancer rate in Nebraska,†the study authors share. “One significant advantage of our study is that we identified the pesticide consistently applied over 22 years in Nebraska counties and then estimated the overall mixture effect of these pesticides on pediatric cancer.†The elevated effect of pesticide mixtures, a reality that is not evaluated in the U.S. Environmental Protection Agency’s (EPA) pesticide registration program, was reported in Oecologia (2008), documenting harm to amphibian populations even if the concentration of the individual chemicals is within limits considered acceptable. (See additional coverage here.) There is a wide body of science highlighting the disproportionate risk of adverse health effects in children with pesticide exposure.

(Beyond Pesticides, March 3, 2025) When the United Nations (UN) adjourned the fifth session of the Intergovernmental Negotiating Committee to develop an international legally binding instrument on plastic pollution, including in the marine environment, Inger Andersen, executive director of the United Nations Environment Programme (UNEP), said, “The world’s commitment to ending plastic pollution is clear and undeniable.†She continued, “Here in Busan [Korea], talks have moved us closer to agreeing on a global legally binding treaty that will protect our health, our environment, and our future from the onslaught of plastic pollution.†In March 2022, the UN Environment Assembly adopted UNEA Resolution 5/14 entitled “End plastic pollution: Towards an international legally binding instrument.† With the Trump Administration shutting down environmental programs and exiting from collaborative international environmental agreements, the work of the world community has taken on elevated importance, given the urgency of health, biodiversity, and environmental crises; so, too, has the work going on at the state level and in local communities across the United States. The interconnectedness of the pesticide and plastic problems was brought into focus recently with a scientific review of articles showing elevated pesticide hazards linked to plastic contamination.

(Beyond Pesticides, February 28, 2025) It is well established that children are more vulnerable than adults to environmental insults such as pesticides, from conception onward. Children living in agricultural areas are exposed differently from those in urban areas. A study of rural children by researchers at Mexico’s Universidad Atónoma de Nayarit compared two communities located less than a quarter of a mile from agricultural fields with one control community located more than a mile away. The study shows that children in the field-adjacent towns are clearly exposed to pesticides and are experiencing cellular distress as a result. The state of Nayarit is on the west coast of Mexico near Mazatlan. Rural children encounter aerial application, spray drift, and erosion. If their parents are agricultural workers and especially if they apply pesticides, they bring home residues on their clothes. Residential storage of pesticides and small children’s propensity to play in the dirt and put things in their mouths exacerbate their exposure. Urban children get hit by pesticides in their homes, schools, and parks. The researchers took blood and urine samples from 431 children aged six to 12 and collected questionnaires as to pesticide exposures from . . .

(Beyond Pesticides, February 27, 2025) In analyzing current scientific literature and data on glyphosate-based herbicides (GBHs), a research article in Environmental Sciences Europe finds that glyphosate (GLY) persists in bones before reentering the bloodstream. The mechanisms in which GLY interacts with important cells for development, called hematopoietic stem cells (HSCs), and breaks and rearranges DNA offer a possible explanation for the heightened risk of cancer, specifically blood cancers like non-Hodgkin lymphoma (NHL), myeloma, and leukemia. “Existing data on GLY/GBH metabolism and genotoxicity provide critical insights into how exposures may be contributing to blood cancers,†according to the study’s author, Charles Benbrook, PhD. Dr. Benbrook continues: “A significant portion of GLY reaching blood moves quickly into bone marrow and then bone, where it can bioaccumulate and persist… Data reviewed herein suggest that a portion of the GLY excreted by most people on a daily basis can be traced to the shedding of calcium-GLY complexes in bone back into the blood supply.†This allows for near-constant contact between glyphosate molecules and hematopoietic stem cells, which are immature cells that can develop into any type of blood cell. Mutations in hematopoietic stem cells can cause blood cancers . . .

*** Beyond Pesticides has recently received an insulting broadside from an environmental group; click here to read the original email and a response from the organization that includes a deep history of Beyond Pesticides’ commitment to ecological and organic farming practices in local food systems that are just. (Beyond Pesticides, February 26, 2025) The National Park Service (NPS) recently announced a settlement agreement regarding the management of northern California’s Point Reyes National Seashore (PRNS) that will result in the closure of 12 out of 14 historic dairy and cattle ranches, including those organically managed, within the park. This decision comes after nearly a decade of legal disputes and negotiations between environmental groups, ranchers, and the NPS, ending 170 years of family ranching, displacing multi-generational farmers—at least 90 farmworker families—and abandoning 77 historic ranch buildings. Critics lambast the agreement as devastating local organic agriculture and food production in West Marin County, which is essential for creating long-term climate solutions. Over the decades since PRNS’ inception, local and national environmental groups have litigated against ranchers and the National Park Service, including demanding range expansion for the native tule elk, which were reintroduced to . . .

(Beyond Pesticides, February 25, 2025) A literature review of over 90 scientific articles in Agriculture documents microplastics’ (MPs) increase in the bioavailability, persistence, and toxicity of pesticides used in agriculture. The interactions between MPs and pesticides enhance the threat of pesticide exposure to nontarget organisms, perpetuates the cycle of toxic chemical use, and decreases soil health that is vital for productivity. “The increasing presence of MPs in agricultural ecosystems has raised concerns about their impact on pesticide bioavailability, efficacy, and environmental behavior,†says study author Kuok Ho Daniel Tang, PhD, a global professor in the Department of Environmental Science at the University of Arizona. He continues, “These synthetic particles interact with pesticides through adsorption and desorption processes, altering their distribution, persistence, toxicity, and uptake by plants and other organisms.†Microplastics in the Environment As Beyond Pesticides has previously reported, microplastics are ubiquitous and threaten not only human health but all wildlife in both aquatic and terrestrial ecosystems. The universal distribution of plastics means that they cannot be avoided. Humans and other organisms take up plastics in the form of microparticles and nanoparticles by inhalation, ingestion, and skin contact every day. Microplastics are about . . .

(Beyond Pesticides, February 24, 2025) The sweeping firing of federal workers, including an estimated 200,000 probationary employees (under one to two years of employment), will have a broad impact on programs to protect health and safety as well as the environment, leaving a critical need for local and state government to fill some of the gaps in critical programs, where possible. A headline in Science magazine warns, “Mass firings decimate U.S. science agencies,†and the dean of the College of Agricultural Sciences at Oregon State University told Oregon Public Broadcasting, “We’ve lost half of our teams, and all of these up-and-coming young scientists. . .so it’s like we’ve lost the next generation of scientists in agriculture and natural resources.†The same applies to important positions across the federal government, affecting every aspect of work necessary to protect public health and biodiversity and address the climate crisis. In response to President Trump’s executive orders and actions, there has been, as The New York Times reports, “new lawsuits and fresh rulings emerging day and night,†raising what experts fear may become a constitutional crisis.

(Beyond Pesticides, February 21, 2025) The prospects for rational environmental policies in the U.S., including commitments to biodiversity and public health protections, are in disarray as the Trump administration sweeps through the federal government without any evaluation of program importance or effectiveness. At the U.S. Environmental Protection Agency (EPA), the destruction is likely to derail or reverse reasonable decisions to ban or restrict numerous toxic chemicals and to bury concern for ecosystem-wide harms. On biodiversity, President Trump has killed a major report, the National Nature Assessment, that had been due for completion on February 11. The assessment is part of the U.S. Global Change Research Program, which produces the national climate assessment, but it was created by an executive order issued under President Biden rather than by Congress. More than 150 experts, including federal employees and volunteers from academia, nonprofits, and businesses, reviewed the state of the nation’s lands, water, and wildlife. The assessment is a U.S.-specific version of a recent global report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), covered here by Beyond Pesticides.

(Beyond Pesticides, February 20, 2024) Researchers at the University of Oregon found that the rollout of genetically engineered corn in the early 2000s, followed by exponential increases in glyphosate-based herbicides, “caused previously undocumented and unequal health costs for rural U.S. communities over the last 20 years.†Their results “suggest the introduction of GM [genetically modified] seeds and glyphosate significantly reduced average birthweight and gestational length.†The conclusions of this study emerge as fossil fuel advocates, including President Donald Trump, are mobilizing to pioneer “energy dominance†despite the market movement toward renewable energy. Just as chemical-intensive farmers and land managers continue to spray synthetic fertilizers and pesticides, a successful rollout of alternatives must rely on feeding the soil rather than the plant. Advocates continue to demand that elected officials and regulators embody the precautionary principle and scientific integrity in decision-making. Given the hostile federal climate on anything relating to holistic solutions, communities are coming together to move beyond input-dependent land management systems and adopt organic criteria of allowed and prohibited substances, mandatory public comment process, independent third-party certification, and a federal advisory board (National Organic Standards Board) consisting of farmers, environmentalists, consumers, scientists, economists, researchers, and other . . .

(Beyond Pesticides, February 19, 2025) In Global Ecology and Conservation, a study of bat species in organic desert date palm plantations highlights the invaluable ecosystem services these beneficial organisms provide. “Bats are crucial in suppressing pest arthropods in agroecosystems, contributing vitally to sustainable agriculture,†the study authors share, which makes supporting bat populations important not just for biodiversity but to help enhance their roles in pest management.   There are various studies connecting organic agriculture and the value it provides for bats and their ecosystem services. (See studies here, here, and here.) While many studies also recognize bat species threatened by pesticides, habitat loss, and climate change, “the importance of bats in agriculture in extreme environments, such as deserts, has received far less attention,†the researchers state. (See previous coverage on pesticide exposure and bats here and here.) They continue, “Date palm plantations represent one of the few productive systems in hyper-arid regions,†noting the study’s novel design. The date palm, primarily grown throughout the Middle East and North Africa, is one of the earliest domesticated fruit trees. “The date palm cultivation’s monocultural nature increases susceptibility to pest infestations due to limited plant diversity, . . .

(Beyond Pesticides, February 18, 2025) With petrochemical pesticides and fertilizers linked to the climate crisis and extraordinary threats to health and biodiversity, recent actions by the Trump administration are highlighting the critical importance of local and state action to mitigate the hazards. On this point, the headline of a National Public Radio article published last week says, â€Trump funding freeze could leave communities on their own as climate threats grow.†Previously, President Trump as a candidate called climate change a “hoax†and has targeted “‘every one’ of President Biden’s policies designed to transition the United States away from fossil fuels,” according to The New York Times. The Guardian reported last October after Hurricane Helene, “As the hurricane continued to ravage the region over the weekend, the former president dismissed global warming in a Saturday speech, and the following day referred to the climate crisis as “one of the great scams of all time.†When considering the historic Palisade fires that began in January in southern California, according to The Guardian, John Abatzoglou, a climatologist at the University of California, Merced, said, “Climate change is adding fuel to the fire and it is absolutely outpacing our ability to adapt in certain areas.†With the . . .

(Beyond Pesticides, February 14, 2025) A study in the European Journal of Preventive Cardiology finds that organic food consumption lowers the risk of developing atherosclerotic cardiovascular disease (ASCVD). Heart health is important not just on Valentine’s Day, but every day. While celebrating with friends and family, consider spreading love in ways that promote long-term health and wellness with an organic meal paired with organic flowers and chocolates. Eliminating exposure to petrochemical pesticides and synthetic fertilizers, such as with an organic diet, mitigates disease risks including brain and nervous system disorders, cancer, endocrine disruption, and cardiovascular disease (CVD). In this latest study, the scientists and doctors analyze registered diagnoses of ASCVD from the Danish National Patient Register in comparison with the diets of a cohort of middle-aged women and men from the Danish Diet, Cancer and Health study. The eligible study participants, including 41,407 men and women of which 5,365 developed ASCVD, filled in a detailed 192-item food frequency questionnaire and a lifestyle questionnaire on their consumption of organic vegetables, fruit, dairy products, eggs, meat, and bread and cereal products.
