(Beyond Pesticides, June 5, 2025) A study conducted in Pennsylvania and published in Environmental Entomology highlights threats to nontarget organisms from neonicotinoid insecticide exposure. Using species of ground beetles as an example, the study documents sublethal behavioral effects as well as decreased week-long survival. This research fills a notable gap in current research, with the authors explaining, âPredatory soil arthropods are under-represented in insecticide toxicity studies, severely limiting our understanding of how insecticides affect soil-invertebrate communities in agroecosystems.â Â The researchers continue, âAs a step toward addressing this issue, we conducted novel acute oral, topical, and soil-based toxicity assays on 9 ground beetle species (Coleoptera: Carabidae) in response to the neonicotinoid insecticides clothianidin, thiamethoxam, and imidacloprid.â The nine carabid beetle species, all common to agroecosystems in central Pennsylvania, were exposed to clothianidin, while additional assays with thiamethoxam and imidacloprid were conducted on the two most abundant species. A wide body of science exists that connects neonicotinoid exposure to health effects in a variety of nontarget organisms. Neonicotinoids, a class of neurotoxic insecticides, act as agonists of nicotinic acetylcholine receptors, âpersist under field conditions, and are water soluble, enabling them to translocate into plants and provide systemic protection of seedlings,â the […]

(Beyond Pesticides, June 3, 2025) Chemical contaminants in wastewater have long been of concern, especially given the significant costs of upgrading wastewater treatment facilities to remove existing and emerging chemicals. In advancing chemical safety, one of the many regulatory determinations that Beyond Pesticides advocates for, prior to the allowance of any toxic chemical use, is the establishment of a realistic cleanup or disposal strategy. Yet, a plethora of petrochemical pesticides flood the market and contaminate the air, soil, water, and crops before poisoning humans and wildlife. A study in the Journal of Environmental Chemical Engineering uses the detectable levels of metabolites (breakdown products) of pesticides in wastewater to gauge exposure to populations living near flower bulb fields throughout the Netherlands. Wastewater samples were collected from five wastewater treatment plants (WWTPs) located in different parts of the Netherlands, with two of the locations (Tollebeek and Lisse) located near flower bulb fields and the other three representing control areas. The study finds that higher levels of chemicals correlate with proximity to agricultural fields and present a heightened health risk. The authors describe wastewater-based surveillance (WBS) as a complementary approach to human biomonitoring that they use âto assess the spatial differences in human […]

(Beyond Pesticides, May 30, 2025) The Making America Healthy Again (MAHA) Commission report, Make Our Children Healthy Again: Assessment, published on May 23, drew criticism from the pesticide industry and agribusiness allies for pointing to independent science that identifies a range of pesticide-induced health hazards.* The Commission, chaired by Robert F. Kennedy, Jr., Secretary of the Department of Health and Human Services (HHS), is composed of the heads of numerous agencies of the federal government and the White House, from the U.S. Environmental Protection Agency (EPA), the U.S. Department of Agriculture (USDA), and the Office of Management and Budget (OMB), to the Assistant to the President and Deputy Chief of Staff for Policy Stephen Miller. The MAHA Commission was established by Executive Order 14212 on February 13, 2025. Despite extensive citations to the science on pesticide hazards, the report includes a section on âCrop Protection Tools,â in which there is a repetition of chemical industry talking points that pesticide residues in food comply with existing tolerances, thus implying that pesticides in food are safe. (See USDA Pesticide Data Program Continues to Mislead the Public on Pesticide Residue Exposure.) However, overall the reportâs introduction sets a tone that seeks to catalogue […]

(Beyond Pesticides, May 29, 2025) A study, published in Environmental Toxicology and Pharmacology, âinvestigates genotoxic effects on farmers in ParaĂba, Brazil, analyzing buccal mucosa cells [cells from inside the cheek] for DNA and cellular damage,â the authors write. In comparing data from 33 pesticide-exposed agricultural workers to 29 unexposed people in a control group, the researchers report that the âfindings revealed significantly higher frequencies of cellular alterations and DNA damage among exposed farmers relative to the control group, with no significant impact from factors such as smoking, alcohol consumption, or family cancer history.â They continue, âThese results underscore the genotoxic risks linked to prolonged pesticide exposure and highlight the necessity for stricter regulatory measures.â As Beyond Pesticides documents in Disproportionate Pesticide Hazards to Farmworkers and People of Color Documented… Again, farmworkers have been excluded from labor and occupational safety protection laws since their inception. The Occupational Safety and Health Administration (OSHA) defers all policy on pesticide protections to the U.S. Environmental Protection Agency (EPA), which has been widely criticized for providing inadequate worker protection standards. This study focuses on workers in Brazil, but represents issues that impact communities worldwide. âThe agricultural sector plays a pivotal role in Brazilâs economy, encompassing […]

(Beyond Pesticides, May 28, 2025)Â A study in Birth Defects Research bolsters existing evidence that agricultural workers, and specifically Hispanic workers in California, are disproportionately bearing the burden of pesticide exposure. Caroline Cox, formerly of the Center for Environmental Health in Oakland, and Jonathan K. London, PhD of the University of California, Davis, examine how currently-used agricultural pesticides unequally affect communities along racial and ethnic gradients. Ms. Cox is a member of Beyond Pesticidesâ board. Using 2022 data from the California Department of Pesticide Regulation (CDPR) and the U.S. Census Bureau, the researchers analyzed county, census tract, and school district data for the percentage of non-Hispanic White population in each population unit and determined the total agricultural use of commercial formulations of pesticides in the same units. CDPR reporting systemâs granular data, including application locations at a resolution of one square mile, and the specific products, dates, and amounts of pesticides used, allows comparison of the data with demographic records. The results show that Hispanicsâ exposure status is robust, independent of current or past data or âindividual pesticides of public health concern.â Pesticides that harm reproductive health were strikingly concentrated among Hispanic populations. There is abundant evidence of racial and ethnic […]

(Beyond Pesticides, May 19, 2025) The Trump administration has removed crucial protections established under the Migratory Bird Treaty Act (MBTA), including those that protect birds from pesticide poisoning. The Migratory Bird Protection Act (MBPA), introduced in May by Rep. Jared Huffman (D-CA) and Rep. Brian Fitzpatrick (R-PA), will restore protections against an âincidental take.â Beyond Pesticides is calling for the protection of migratory birds and the restitution of funds to implement the law. This is not the first time that President Trump has reduced protection for migratory birds. In his first term (2017), the Department of the Interior issued a policy that relieved industries of the requirement to protect birds, and they will no longer be held accountable for bird deaths. In addition, the agency is expected to propose rules to make this policy change permanent. >> Tell your U.S. Representative to cosponsor the Migratory Bird Protection Act (H.R. 3188). MBTA was passed in 1918 to protect migratory birds soon after the last Passenger Pigeon died in captivity, followed by the last Carolina Parakeet. MBTA originally resulted from the loss of birds due to a number of threatsânotably at the time, the collection of bird feathers. It prohibits the take (including killing, […]

(Beyond Pesticides, May 8, 2025) A study, published in Environmental Pollutants and Bioavailability, assesses the impacts on Nile tilapia (Oreochromis niloticus) with subacute and chronic exposure to thiamethoxam, a neonicotinoid insecticide, and finds genotoxicity, oxidative stress, and changes in tissue structure, among other threats to organ function and overall fish health. âThe study focused on biochemical markers, genetic damage, pesticide residue levels in fish flesh, and histopathological changes in fish exposed to different concentrations of thiamethoxam,â the authors state. The threats do not end there; human health is also at risk from the consumption of these contaminated fish. âUnfortunately, neonicotinoids, rapidly washed into surface water from agricultural areas, pose a significant threat to environmental water quality and can harm non-target species, particularly aquatic organisms,â the researchers state. The accumulation of these chemicals leads to âultimately harming both aquatic ecosystems and human health,â they say. In particular, the study highlights that prolonged exposure to high doses of thiamethoxam can cause âsignificant negative effects on fish health,â the authors note. They continue: âThis exposure led to increased levels of urea and ALT [alanine aminotransferase] in the blood, indicating potential damage to the kidneys and liver. Additionally, thiamethoxam caused oxidative stress, as evidenced […]

(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 Montaguâs harrier (Circus pygargus) nestlings, the authors âshed light on an overlooked collateral effect of pesticides, i.e., a general modification of gut bacterial assemblages,â 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. âAdditionally, our findings support the ‘One Health‘ framework, stressing the interconnectedness of wildlife, ecosystem, and human health, particularly in pesticide-affected agricultural areas,â the researchers share. âThe gut microbiota is crucial for host health and can be impacted by various environmental disruptions, yet the effects of multiple pesticide exposures on farmland organismsâ microbiomes remain largely unexplored,â the authors state. In the study, they âassessed microbiota changes in a wild apex predator exposed to multiple pesticides in agricultural landscapes,â which âprovides evidence of pesticide impacts on wildlife gut microbiota, highlighting links between pesticide exposure and changes in microbiota composition,â the researchers note. The Montaguâs harrier, as an apex predator, serves as a âbio-sentinelâ or bioindicator species for assessing ecosystem health. âAs top-level predators […]

(Beyond Pesticides, April 25, 2025) A novel study in Chemosphere finds impacts on male fertility in a bee species (Osmia bicornis) with exposure to sulfoxaflor, a systemic sulfoximine insecticide with similar mechanisms to neonicotinoids. âFor the first time, we demonstrate that short-term chronic, field-realistic exposure to a common pesticide reduced pre-copulatory display (36%) and sounds (27%) [courtship behaviors], increased the number of copulations (+110%) and the mating duration (+166%), while finally reducing sperm quantity (25%) and mating success (43%),â the researchers report. They continue, âOur research raises considerable concern on the impact of field-realistic, low sublethal pesticide levels on the fertility and reproductive success of pollinators.â Mating behaviors and the ability to successfully reproduce determines the survival of species. As the authors state: âMating disorders may therefore contribute to the recent decline in insect and pollinators’ health worldwide. While the impact of pesticides on pollinators is widely considered as a driving factor for reducing pollinators’ health, their effect on mating behaviour and male fertility remains widely overlooked.â The red mason bee (O. bicornis) can âprovide essential pollination service for both crops and wild plants sustaining food production and biodiversity while serving as a bioindicator of environmental health.â The abundance and […]

(Beyond Pesticides, April 23, 2025) Recent reviews of scientific literature, in both Chemosphere and Reports in Public Health, associate Parkinsonâs disease (PD), the second most prevalent neurodegenerative disease globally, with pesticide exposure. âGiven the pervasive nature of pesticide residues in everyday food consumption and inadequate monitoring of their long-term toxicological impacts, the role of pesticide exposure as a modifiable risk factor for neurological disorders, including PD, warrants urgent attention,â the researchers state in the article in Chemosphere. In describing the history of Parkinsonâs and previous research, the authors in Reports in Public Health note that while PD etiology is not fully understood, it is a multifactorial disease. âHereditary factors are present in approximately 10% of diagnosed cases of Parkinsonâs disease, presenting early onset; while the other 90% of cases are categorized as idiopathic or sporadic Parkinsonâs disease, occurring in older individuals and may be associated with exposure to environmental agents,â the researchers say. This disease, first described by English physician James Parkinson, M.D. in 1817, involves neurochemical changes that present as âthe appearance of cardinal motor symptoms, such as bradykinesia, rigidity, postural instability, and rest tremor, which are essential for the clinical diagnosis of the disease,â the researchers note.

(Beyond Pesticides, April 18, 2025) A recent study published in Foods assesses the ability of the fungicide azoxystrobin (AZX) and naturally occurring toxins produced by certain fungi, known as mycotoxins, to display effects of cytotoxicity (cell damage). These effects were evaluated using three common mycotoxins found in food, including ochratoxin A (OTA), deoxynivalenol (DON), and T-2 toxin as mixtures with AZX within human hepatocarcinoma (HepG2) cell cultures. In analyzing combinations of these compounds at sublethal concentrations, the authors find modified toxicological behavior and synergistic effects that highlight the complexities of chemical mixtures, and potential threats to liver health through dietary exposure to both toxicants and toxins, that are not adequately regulated for their interactions. While fungicides, like azoxystrobin, are intended to prevent or control fungal diseases, resistance to these pesticides can increase the presence of fungi, and subsequent mycotoxins, on crops. This scenario allows for co-exposure of fungicides and mycotoxins within food products that present a risk to consumers. These chemicals can threaten human health individually, as the researchers confirm in their study, but present a greater threat in combination. The mixture of AZX with all three mycotoxins exhibits the highest toxicity, with synergistic effects at all tested concentration levels. […]

(Beyond Pesticides, April 17, 2025) A literature review in Reproductive Sciences finds glyphosate (GLY) and glyphosate-based herbicides (GBH) impact womenâs reproductive health, adding to the long list of documented harm from this widely used weed killer. The authors note, âConsidering the widespread use of GLY, the controversy regarding its endocrine-disrupting potential and reproductive toxicity, and the innumerable lawsuits filed against Bayer and Monsanto by consumers for morbidities related to Roundup™ exposure, the purpose of this review is to summarize the current literature on the potential adverse effects of GLY and GBHs on the female reproductive tract and discuss possible clinical implications on reproductive health outcomes, including polycystic ovarian syndrome (PCOS), endometriosis, and female fertility.â Glyphosate and aminomethylphosphonic acid (AMPA), the primary metabolite (breakdown product) of GLY, are found throughout the environment in soil and water, as well as in samples of blood, urine, seminal plasma, and breast milk. Studies have detected residues in farmworkers, as well as “in the urine of 60â80% of the general public in the USA, including pregnant women and children.â (See studies here, here, and here.) The ubiquitous use of GLY and GBH, and subsequent persistence, threatens the health and well-being of all. Previous studies have […]

(Beyond Pesticides, April 11, 2025) In a new report by Save our Seeds Foundation on Future Farming, a consortium of EU-based scientists and bioethicists raise concerns about the implications and threats of generative artificial intelligence (GAI) for genetic engineering. Artificial intelligence will impact all aspects of society, including the acceleration of genetic editing tools that may lead to increased risks of harmful traits/genetic data being incorporated into products on the global marketplace. Organic farmers, conservationists, and public health professionals who collaborate with Beyond Pesticides grow increasingly concerned about the long-term impacts of deregulation and ongoing federal funding freezes and firings on needed regulatory oversight of the tech sector, including AI. Review of Save our Seeds Report So, what is artificial intelligence (AI)? AI is a broad field that focuses on building machines and systems that can think, learn, and solve problemsâincorporating elements of human behavior. It powers things like voice assistants, self-driving cars, and recommendation systems on apps like Netflix or Spotify. In short, AI is designed to understand information, make decisions, and complete tasks intelligently. Generative AI, however, is an extension of AI focused on creativity. The main goal is to generate new contentâwhether in writing, photography, video, music, […]

(Beyond Pesticides, April 10, 2025) The Los Angeles Board of Supervisors has voted to declare today, April 10, Dolores Huerta Day, honoring the lifelong efforts of social justice activist Dolores Clara FernĂĄndez Huerta on the celebration of her 95th birthday. In the words of Chair Pro Tem Hilda L. Solis, according to Colorado Boulevard, âDolores Huertaâs contributions to Los Angeles County and to Latinos across the country have inspired generations of leaders fighting for justice for all. Now more than ever, we honor Dolores Huerta for her work as one of the most influential labor activists of our time… may her legacy continue to light a fire in us all.â Ms. Huerta, in accepting the recognition, noted, âI accept this on behalf of Los Angelesâ working people, especially our immigrant community, whose labor supports families and children. The Supervisors have gone above and beyond to assist immigrants, and as we face challenges ahead, itâs vital to continue supporting their bold, compassionate leadership for our most underserved communities.â This action follows prior recognition from then Acting Governor of California Eleni Kounalakis in 2024 and the state of Washington in recognizing Ms. Huertaâs decades of leadership.

(Beyond Pesticides, April 8, 2025) A comprehensive literature review in Environment & Health analyzes evidence from human biomonitoring, epidemiological studies, and toxicological studies that link adverse effects on womenâs reproductive health, specifically impacting the ovary, to pesticide exposure. In examining the scientific literature, consisting of over 200 studies performed in the last 25 years, the authors find pesticide exposure threatens womenâs health through ovarian dysfunction. âEpidemiological studies have shown that pesticide exposures are associated with early/delayed menarche [first occurrence of menstruation], menstrual cycle disorders, early menopause, long time to pregnancy, polycystic ovary syndrome, primary ovarian insufficiency, infertility, and implantation failure in women,â the researchers state. They continue, âBoth in vivo [in animals] and in vitro [in cells] studies have shown that exposure to pesticides disrupts the estrous cycle, reduces the follicle pool, alters hormone levels, and impairs oocyte [egg] maturation.â These reproductive implications are noted with many different classes of pesticides, such as insecticides, including organochlorine pesticides (OCPs), organophosphates (OPs), pyrethroids, and neonicotinoids, as well as herbicides and fungicides. The authors, however, comment on present research gaps: âMuch of the available epidemiological evidence focuses on legacy insecticides, such as OCPs, and a subset of insecticides that are still in use […]

(Beyond Pesticides, April 4, 2025) In March, the California Department of Pesticide Regulation (DPR) announced the launch of SprayDays California, âa first-of-its-kind statewide system designed to provide transparent, accessible and timely notifications and information about the use of specific pesticides[,]â according to the agencyâs press release. The state says that notification will occur in âadvance of the scheduled use of California restricted material pesticides in production agriculture.â Growing out of the passage of AB 617 Community Emissions Reduction Act in California, passed in 2017, farmworker safety advocates have long been urging an implementation strategy that provides notification of pesticide spraying. In late 2017, the California Air Resources Board (CARB) began implementation of AB 617, a bill enacted with the stated intent of addressing the air quality crisis in many communities of predominantly people of color who are disproportionately harmed by toxic chemicals. While the overall goal of the law is to reduce air pollution in these communities, farmworker advocates have sought to operationalize a pesticide spraying notification system to warn communities when nearby spraying is scheduled to take place. The idea behind notification programs and transparency in government is that it enables those potentially exposed to take precautionary measures to […]

(Beyond Pesticides, April 3, 2025) As highlighted by Beyond Pesticides in recent comments to the U.S. Environmental Protection Agency (EPA), chlorpyrifos (CPF) has been under scrutiny for decades due to associated adverse health effects, noted particularly in the extensive and consistent scientific evidence of neurotoxic dangers to childrenâs health. The latest research on CPF, published in Environmental Toxicology and Genes & Diseases, reveals additional threats to the immune system and male reproduction that are not captured in current EPA risk assessments of chlorpyrifos and raises serious health questions, given that residues are found throughout the food supply. CPF, a widely used organophosphate insecticide in agriculture, is a cholinesterase inhibitor that binds irreversibly to the active site of an essential enzyme for normal nerve impulse transmission, acetylcholine esterase (AChE), inactivating the enzyme. Many insecticides, including organophosphates and carbamates, target AChE, causing them to be highly toxic to both insects and mammals that have this enzyme as a crucial part of their nervous systems. The history of chlorpyrifos exemplifies the failure of pesticide law and policy, as this chemical, among many others, not only has direct adverse health effects but is contributing to the climate crisis, biodiversity collapse, and disproportionate levels of […]

(Beyond Pesticides, April 2, 2025) In examining prenatal residential proximity of documented pesticide spraying in California to the menstrual cycle characteristics of 273 Latina adolescents, researchers report in the American Journal of Epidemiology a positive association between exposure to the insecticide methomyl and heavy bleeding. Other pesticides appear to influence menstrual symptoms as well. âAdolescentsâ menstrual cycle characteristics can be âvital signsâ of health and impact quality of life,â the authors share. They continue, âTo our knowledge, this is the first study to examine the association between prenatal pesticide exposure and menstrual outcomes in adolescents of any demographic group.â Menstrual cycle characteristics, such as dysmenorrhea (painful or uncomfortable menstrual cramps), irregularity, and heavy menstrual bleeding, can also be indicators of underlying health conditions, including endometriosis, polycystic ovary syndrome (PCOS), thyroid dysfunction, and bleeding disorders. By associating the pesticide exposure of mothers during pregnancy to impacts on their children, the researchers highlight important health risks for women and young girls that are often disregarded. âThe prenatal period is a critical period of reproductive development that may be particularly sensitive to endocrine disruption,â the researchers share. As previously reported by Beyond Pesticides, endocrine-disrupting chemicals are any synthetic or natural compounds that hinder […]

(Beyond Pesticides, March 27, 2025) In Ecotoxicology, results of a study on Nile tilapia (Oreochromis niloticus) exposed to florpyrauxifen-benzyl (FPX) suggest the new herbicide causes oxidative stress (imbalances affecting the bodyâs detoxification abilities that lead to cell and tissue damage), with specific genotoxic (damage to genetic material) and hepatotoxic (damage to the liver) effects on nontarget species. The authors state: âAccording to the available literature, no data exist on the toxicity of FPX in fish. Therefore, this study aims to investigate, for the first time, the potential toxicity and associated mechanistic effects of the pyridine-carboxylic acid herbicide (FPX) on the non-target species, Nile tilapia.â According to the Wisconsin Department of Natural Resources, âFlorpyrauxifen-benzyl is a systemic herbicide (i.e., it moves throughout the plant tissue). It is a WSSA Group 4 herbicide, meaning that the mechanism of action is by mimicking the plant growth hormone auxin and causing excessive elongation of plant cells, ultimately killing the plant.â The researchers, from Menoufia University, the Agricultural Research Center, and Cairo University in Egypt, focus on FPX as it is the active ingredient in Divixton 2.5% EC, a newly released herbicide used in rice fields and applied directly to freshwater aquatic bodies for emergent […]

(Beyond Pesticides, March 25, 2025) An editorial in Expert Review of Cardiovascular Therapy finds that triazole fungicides pose a significant risk of cardiotoxicity with âgrowing concerns regarding their safety for human health, especially in long-term exposure,â the authors share. After analyzing the known mechanisms of cardiotoxicity of triazole pesticides in mammals, they conclude that âthe most effective approach to mitigating triazole-induced cardiotoxicity lies in prevention.â Triazoles, a class of fungicides, target fungi by inhibiting the biosynthesis of ergosterol, an essential component of their cell membranes. As the researchers share, âCompounds such as tebuconazole, propiconazole, and difenoconazole are among the most used triazoles in agriculture.â Triazoles are utilized as antifungal medications, despite the rise of resistant infections, in addition to their use as systemic pesticides on many fruit and vegetable crops, including grapes, wheat, corn, and soybeans.  As Beyond Pesticidesâ previous coverage indicates, many triazole fungicides in the U.S. are registered for use despite evidence of endocrine disruption established over a decade ago in a U.S. Geological Survey report. These pesticides exhibit common mechanisms of toxicity often disregarded in U.S. Environmental Protection Agency (EPA) risk assessments, with a multitude of studies showcasing the myriads of health threats that the agency does […]

(Beyond Pesticides, March 21, 2025) Sin maĂz, no hay paĂs â âWithout corn, there is no countryâ (Mexican saying) In the face of U.S. efforts to require Mexico, under a trade agreement, to import genetically engineered corn, last week the Mexican legislature approved a constitutional amendment identifying native corn as âan element of national identityâ and banning the planting of GE seeds. This brings to a head a clash over issues of food sovereignty and security, genetic integrity, health protection, and environmental safety. In 2020, the Mexican government committed to phasing out the importation of genetically engineered (GE) corn by 2024. Mexico had also planned to ban by April 1, 2025, the weed killer glyphosate, integral to GE corn productionâbut recently delayed its decision. These actions by Mexico triggered vigorous pushback by the U.S., resulting in the formation of a panel under the U.S.-Mexico-Canada Agreement (USMCA) to decide which country was in the right. The USMCA, negotiated in 2018 during President Trumpâs first term, replaced the North American Free Trade Agreement. Under USMCA, parties can adopt measures to protect human animal or plant life or health. However, in December 2024, the USMCA panel ruled in favor of the U.S., rejecting […]

As the article says: âWhether they hop around the prairie, dabble in wetlands, flit through forests, or forage along the shore, birds are suffering rapid population declines across the United States… If these habitats are struggling to support bird species, itâs a sign that theyâre not healthy for other wildlife, or even humansâbut working to restore them will have benefits across ecosystems.” The 2025 edition of the State of the Birds report, showcasing a status assessment of the health of the nationâs bird populations, was cultivated by scientists from bird conservation groups through the U.S. Committee of the North American Bird Conservation Initiative (NABCI). The report notes, âDespite ample evidence that conservation can work, the status quo approach to conservation is not turning bird populations around.â As NABCI shares, the report contains â[s]obering evidence that Americaâs birds continue to decline across the board.â They continue, saying: âBirds are telling us that the habitats […]

(Beyond Pesticides, March 19, 2025) In a major win for small-scale food producers and peasant farmers in Kenya, âthe Kenya Court of Appeal blocked the Kenyan government from importing genetically modified organisms (GMOs) into the country[,]â according to a press release by Alliance for Food Sovereignty in Africa (AFSA)âan alliance of organizations and movements across the continent advocating for agroecology and food sovereignty. âWe celebrate this ruling as a major victory for small-scale farmers across Kenya,â said David Otieno, a small-scale farmer and member of the Kenyan Peasants League, a social movement consisting of consumers, farmers, pastoralists, and fishers rallying against the multinational corporate takeover of food systems in Kenya. Mr. Otieno continued: âGMOs are not the solution to food insecurity in our country. Instead, they deepen dependency on multinational agribusinesses, threaten biodiversity, and compromise farmersâ ability to control their food systems.â Genetically engineered seeds are designed to be resistant to commonly used pesticides, including the weedkiller glyphosate, which locks farmers into dependence on multinational corporations rather than their own ability to practice seed saving and enhance their food sovereignty. This battle for control over the ownership of land and seeds in Kenya resonates with the growing movement of consumers, […]
