(Beyond Pesticides, June 2, 2023) Scientists have identified 97 different types of pesticides and flame retardants in primate fecal samples, recently reporting their results in the journal Biology Letters. In Uganda’s Kibale National Park, researchers studied the chemical exposure of four species of primates (chimpanzees, Ugandan red colobus, olive baboons and red-tailed monkeys), adding to previous research on the subject. The chemicals demonstrate a measurable effect on primate growth and development, sparking considerable unease as to the future health of these critical species. This study shows how even within a protected national park, wildlife species are at risk from chemical pollution. According to advocates, the use of dangerous pesticides and flame retardants, therefore, must be entirely stopped in order to protect the future viability of wildlife species. Scientists collected a total of 71 fecal samples from the four chosen species to measure levels of chemicals and hormones in a noninvasive manner. After sample analysis, researchers highlight three main groups of chemical pollutants: organochlorine pesticides (OCPs), brominated flame retardants (BFRs), and organophosphate esters (OPEs). Although in a protected area, wildlife species encounter humans through tourism, research, and human development surrounding the park. As these pesticides are so prevalent in areas of […]

(Beyond Pesticides, October 7, 2022) Pyrethroid insecticides are associated with the growing worldwide epidemic of non-alcoholic fatty liver disease (NAFLD), a condition that causes swelling of the liver and can eventually lead to cirrhosis, cancer, or liver failure. According to research published in Environmental Science and Ecotechnology, exposure to pyrethroids like bifenthrin can induce gut microbiota dysbiosis (an imbalance in microorganisms in the intestines). This dysbiosis results in abnormal lipid (fat) metabolism and subsequent accumulation of lipids in liver cells, contributing to NAFLD development. Gut microbiota plays a crucial role in lifelong digestion, immune and central nervous system regulation, as well as other bodily functions. Through the gut biome, pesticide exposure can enhance or exacerbate the adverse effects of additional environmental toxicants on the body. Since the gut microbiome shapes metabolism, it can mediate some toxic effects of environmental chemicals. However, with prolonged exposure to various environmental contaminants, critical chemical-induced changes may occur in the gut microbes, influencing adverse health outcomes. Considering NAFLD is becoming the most prevalent form of liver disease, impacting at least 25 percent of the globe, and a growing body of evidence demonstrates the significance gut microbiota play in overall health, safety analyses that currently do not consider the […]

(Beyond Pesticides, October 4, 2022) A study published in Environmental Pollution finds pyrethroid insecticides contribute to a secondary source of contamination in water resources. Various pyrethroids, including bifenthrin, are detectable in urban catch basins (storm drains) that collect runoff water before draining into the open environment. There is a lack of information regarding the pesticides’ presence in urban catch basins. However, pesticide contamination in water resources is historically commonplace and widespread throughout U.S. rivers and streams, with at least five different pesticides present in 90 percent of water samples. Moreover, thousands of tons of pesticides not only enter waterways (e.g., rivers, streams, lakes, oceans) around the U.S. through urban catch basins but agricultural and nonagricultural sources as well, contaminating essential drinking water sources, such as surface water and groundwater. Reports like these are essential for determining appropriate regulatory action to protect the human, animal, and environmental health from chemical toxicant contamination, especially if chemical contamination is highly detectable. The study notes, “The high detection frequency of bifenthrin and overall pyrethroid concentrations, especially for particle-bound residues, suggest that underground urban catch basins constitute an important secondary source for extended and widespread contamination of downstream surface waters by pesticides such as pyrethroids in urban […]

(Beyond Pesticides, September 15, 2022) A review published in Scientific African finds pesticide exposure contributes to the increase in non-communicable diseases (NCDs) in Tanzania, reflecting implications for global health. There are four main NCDs, including cardiovascular diseases, cancers, respiratory diseases, and endocrine-disrupting diseases like diabetes. These diseases have no bacterial, viral, or fungal causes, but are chronic diseases with risk factors like genetics, tobacco/alcohol use, physical activity, and diet, thus lacking transmission between people. However, research is now investigating the role environmental factors play in NCD risks, such as outdoor and indoor air pollution, exposure to chemicals, radiation, and occupation. Regardless of whether working together or separately, these risk factors contribute to NCDs and subsequent health conditions. Non-communicable diseases are on the rise, and the World Health Organization (WHO) classifies non-communicable diseases as the number one cause of death globally, affecting 41 million individuals. Moreover, WHO estimates NCD death rates to increase by 17 percent in the next decade, significantly surpassing deaths from communicable, maternal, perinatal, and nutritional diseases combined. Therefore, the report notes, “This review is informative to the policy, practices, and intervention towards the existing situation of pesticides in Tanzania. In addition, it calls for further investigation of the absence of data […]

(Beyond Pesticides, September 8, 2022) A study published in Environmental Pollution finds parental exposure to real-world, sublethal concentrations of pesticide residues on grains is a major contributor to unfavorable offspring development among foraging birds. Parents’ ingestion of grains with conventional pesticide residues, whether from contaminated or pesticide-treated seeds, results in chronic exposure that adversely affects offspring health, even at low doses. The adverse effects pesticides and other environmental pollutants have on birds are amply documented and researched. Although many studies evaluate acute or chronic health implications associated with pesticide exposure in a single generation, there is a lack of information on multi-generational impacts that can provide vital information on the fundamental survivability or fitness of bird species. Considering this study emphasizes parental exposure to environmental pollutants can have adverse consequences for future generations, it is necessary that future risk assessments for birds address these implications when implementing agricultural pesticide policies. The study notes, “[S]ublethal effects of such compounds [pesticides] on non-target species should be included in the regulation. Moreover, as agroecosystem pollution is not resulting only from pesticides, there is an urgent need to analyze cocktail effects, not only between molecules of pesticides but also between pesticides and other pollutants such as […]

(Beyond Pesticides, March 23, 2022) A study published in Nature Reviews Earth & Environment warns that thawing of permafrost (a ground that remains completely frozen for two or more years) in the Arctic region can prompt the reemergence of greenhouse gases (e.g., methane and carbon dioxide), microbes, and chemicals (e.g., banned pesticides like DDT). Past research finds gases, microbes, and chemicals drift near the poles, becoming entrapped in ice under the accumulating snowfall. As the global climate continues to rise and the climate crisis worsens, studies like this show significant effects, as ice encapsulating these toxic chemicals is melting. Upon melting, some chemicals can volatilize back into the atmosphere, releasing toxicants into the air and aquatic systems, with the ensuing consequences. Microbes frozen for thousands to millions of years can also emerge from thawing permafrost, with unknown implications on human, animal, and ecosystem health. The melting permafrost is already beginning to impact infrastructure, creating sinkholes that damage roads, trees, and utility poles. Moreover, mixtures of chemicals, microbes, and greenhouse gases (GHGs) in permafrost are difficult to assess. Therefore, studies like this highlight the need to evaluate the health and ecological effects of melting arctic permafrost (and glaciers) from anthropogenic (human)-induced climate change. […]

(Beyond Pesticides, February 4, 2022) In January, the U.S. Department of Agriculture (USDA) issued its 30th Pesticide Data Program (PDP) Annual Summary report (which evaluates each year the presence of pesticide residues on produce) and misleads the public on the safety of food and agricultural practices. This 2020 report concludes that more than 99% of the produce samples tested showed residues below established U.S. Environmental Protection Agency (EPA) benchmark levels. At first blush, this sounds very reassuring, but Beyond Pesticides maintains that there is (always) more to the “safety” story, not least of which are serious deficiencies in EPA’s establishment of those “tolerances.” Those flaws include a lack of risk assessment for vulnerable sub-populations, such as farmworkers, people with compromised health, children, and perhaps, cultural/ethnic and regional sub-groups of the general population, and a failure to fully assess serious health outcomes such as disruption of the endocrine system (which contributes to numerous serious diseases). For everyone, Beyond Pesticides recommends choosing organic produce whenever possible — the vast majority of which does not contain synthetic pesticide residues. The PDP report asserts that “the data . . . illustrate that residues found in agricultural products sampled are at levels that do not pose […]

(Beyond Pesticides, November 9, 2021) Replacing a modern, â€western’ diet of highly processed foods with a Mediterranean diet filled with conventional, chemically-grown fruits and vegetables triples exposure to toxic pesticides, according to research recently published in The American Journal of Clinical Nutrition. However, this disturbing change can be eliminated by eating a Mediterranean diet consisting entirely of organic food, which is not sprayed with synthetic pesticides. The advantages of the Mediterranean diet, often ranked as the â€best diet’ and emphasized by medical practitioners for its health benefits, now appear to depend on the production practices involved in the meals an individual eats. “There is growing evidence from observational studies that the health benefits of increasing fruit, vegetables and wholegrain consumption are partially diminished by the higher pesticide exposure associated with these foods,” said study coauthor Per Ole Iversen, MD. “Our study demonstrates that consumption of organic foods allows consumers to change to a healthier diet, without an increased intake of pesticides.” Researchers began their investigation by establishing a randomized trial consisting of 27 adults, all of whom were postgraduate student volunteers on a study abroad course in Greece. The experiment lasted a total of five weeks, including a two-week intervention in the […]

(Beyond Pesticides, July 08, 2021) A Portland State University (PSU) study finds oysters of varying distances from wastewater discharge pipes along the Oregon and Washington state coast contain low levels of chemical contaminants. Although wastewater treatment facilities clean water draining from sinks and toilets, the process does not adequately remove all contaminants. The process can leave behind pharmaceutical drugs and personal care products (e. g., shampoos, make-up, deodorant) residues in treated water. PSU has already found that pesticides from the forestry industry threaten clams, mussels, oysters (bivalves) along the Oregon coast. Marine ecosystem pollution is difficult to track and measure, and pesticide regulations can invoke variations in water quality requirements through discrepancies in buffer zones and application concentrations. The combined presence of pesticides, medicine, and personal care products in aquatic environments has direct implications for species and ecosystem health and indirect consequences for human well-being. Therefore, studies like this can help government and health officials develop strategies to reduce the number of chemicals entering aquatic ecosystems, with researchers noting officials can “better understand whether contaminant exposure affects oyster condition.” Researchers wanted to evaluate how proximity to wastewater facilities affects variations in aquatic pollution. Thus, scientists transplanted one-week-old Pacific oysters along the Oregon and […]

(Beyond Pesticides, April 22, 2021) Past maternal exposure to the pesticide dichlorodiphenyltrichloroethane (DDT) during pregnancy can increase the risk of breast cancer and cardiometabolic disorders (e.g., heart disease, obesity, diabetes) up to three successive generations, according to a new study published in Cancer Epidemiology, Biomarkers & Prevention. Although previous studies highlight early life or in utero exposure to DDT increasing breast cancer risk later in life, this study is the first to note generational effects on grandchildren’s health. DDT continues to adversely affect the health of the U.S. population, nearly 50 years after its ban. However, this ban is not global, as many countries still use or manufacture the chemical compound. Furthermore, residues of DDT metabolite, DDE, continue to readily contaminate food and water worldwide. Therefore, studies like these highlight the need to investigate how first-generation pesticide exposure can impact future generational health in order to prevent adverse health outcomes, especially during sensitive developmental periods (i.e., in utero, infancy/childhood). The study researchers note, “Discovery of actionable biomarkers of response to ancestral environmental exposures in young women may provide opportunities for breast cancer prevention.” To assess the association between multi-generational health risks and chemical exposure, researchers used the Public Health Institute’s Child […]

(Beyond Pesticides, March 4, 2021) A new study finds glyphosate use stimulates soil erosion responsible for releasing banned, toxic pesticide chlordecone (Kepone), which was used in banana production. For years, an unknown pollution source continuously contaminated water surrounding islands in the French West Indies (Martinique and Guadeloupe). However, researchers from the University of Savoie Mont Blanc in France have found that chlordecone—extensively used on banana farms from 1972 to 1993—is the contamination culprit. Glyphosate is the most popular herbicide in the world, thus ubiquitous in the environment. Therefore, it is vital to understand the implication glyphosate use has on soil health and the potential re-release of soil-bound, toxic contaminants into the surrounding environment to safeguard human health. Researchers note, “[Chlordecone] fluxes drastically increased when glyphosate use began, leading to widespread ecosystem contamination. As glyphosate is used globally, ecotoxicological risk management strategies should consider how its application affects persistent pesticide storage in soils, transfer dynamics, and widespread contamination.” Conventional pesticide use contaminates soil and their respective Critical Zone (CZ) compartments. These CZ compartments interact between the four main spheres (i.e., hydrosphere, biosphere, lithosphere, and atmosphere) of the Earth to support life. Recent decades demonstrate an increase in soil erosion due to sediment changes […]

(Beyond Pesticides, September 18, 2020) In late August, Consumer Reports magazine (CR) issued a report titled, “Stop Eating Pesticides,” which offers consumers a rating system CR developed and employed to help them “get the health benefits from fruits and vegetables while minimizing [the] risk from toxic chemicals.” In addition to providing its analysis and ratings of the pesticide risk of a variety of produce items, CR recommends eating organically grown and raised foods whenever possible. It also makes a host of recommendations on federal pesticide policies and emphasizes the importance of maintaining the integrity of the National Organic Standards (of the USDA-housed National Organic Program). Beyond Pesticides appreciates that this mainstream publication has arrived at many shared, science-based assessments of the risks of pesticides. That said, a wholesale transition to organic and regenerative agriculture — rather than making the public figure out which fruits and vegetables are “safer” or “less safe” — is the real answer to the health risks of pesticides in the food supply, according to Beyond Pesticides. The CR analysis used data from the U.S. Department of Agriculture’s (USDA’s) Pesticide Data Program for 2014–2018. Those pesticide residue data were compiled from tests of approximately 450 pesticides across 24,000 […]

(Beyond Pesticides, September 10, 2020) A new analysis by Science of Cannabis Laboratories Inc. (SC Labs) finds detectable concentrations of pesticides and heavy metals in rolling papers, with hemp/blunt wraps and cellulose-based rolling papers containing the highest levels of contaminants. The analysis follows a SC Labs’ finding of high levels of chlorpyrifos—a neurotoxic, organophosphate insecticide—in the rolling paper of pre-rolled cannabis, which was undergoing compliance testing. Although the rolling paper regulations generally track standards for toxic tobacco products (which means there is very little meaningful regulation), the rolling paper use with cannabis may add an addition layer of scrutiny since some statewide cannabis regulations and independent certifications adhere to stricter guidelines similar to organic practices. Researchers note the goals of the experiment “were to assess the exposure risks to the consumer as well as identify any potential liabilities for cannabis producers who use these products to make their pre-roll products.” This report, and others like it, are significant as cannabis use expands in in the U.S. and around the world, and given that one of the most popular ways to consume cannabis product is as a rolled cigarette. Study author and president of SC Labs Josh Wurzer, Ph.D., said, “This [issue] is something that cannabis and paper […]

(Beyond Pesticides, August 6, 2020) New research finds that a decline in wild pollinator abundance, notably wild bees, limits crop yields in the U.S., according to the study, “Crop Production in the USA Is Frequently Limited by A Lack of Pollinators.” The study results, published in the journal Proceedings of the Royal Society B, find the annual, national average value of wild bee pollination for the most economically important and pollinator-dependent crops is approximately $1.5 billion, with the total value of all U.S. pollinator-dependent crops equaling $50 billion annually. The United Nations states that 75% of the 115 top global food crops depend on insect pollination, with one third of all U.S. crops dependent on pollinators, according to the U.S. Department of Agriculture (USDA). However, research finds that many insect populations are declining by half with a third threatened by extinction, including managed and wild pollinators, mainly due to habitat fragmentation, climate change, and extensive pesticide use. With the global reliance on pollinator-dependent crops increasing over the past decades, a lack of pollinators threatens food security and stability. The researchers in the study note, “Our findings show that pollinator declines could translate directly into decreased yields or production for most of the crops studied, […]

(Beyond Pesticides, July 16, 2020) Long-term exposure to sublethal (low-level) concentrations of the neonicotinoid in soil negatively affects the health and behavioral development of black garden ants (Lasius niger) colonies, according to a study published in Communications Biology by scientists at the University of Bern, Switzerland. Ants are one of the most biologically significant insects in the soil ecosystem, acting as ecosystem engineers. Their burrowing behavior aerates the soil, allowing oxygen and water to penetrate down to plant roots. Additionally, ants increase soil nutrient levels by importing and accumulating organic material like food and feces, thus enhancing nutrient cycling. Like many other insects, ants are unfortunate victims of the global insect apocalypse or population decline, and much research attributes the recent decline to several, including pesticide exposure. Broad-spectrum pesticides, like neonicotinoids, indiscriminately kill pests and nontarget organisms alike, as their ubiquitous use contaminates soils, even in untreated areas. This study highlights the necessity of rethinking chemical pest management, developing sustainable agricultural practices that reduce the use of agrochemicals, like pesticides, to prevent permanent environmental ecosystem damage. Researchers in the study note, “To prevent irreparable damages to functioning ecosystems, [we] suggest to either fully incorporate long-term effects in risk assessment schemes, or to make a shift […]

(Beyond Pesticides, May 21, 2020) Use of the herbicide dicamba increases humans’ risk of various acute and chronic cancers, according to research published in the International Journal of Epidemiology by the National Institutes of Health (NIH). Many pesticides are “known or probable” carcinogens (cancer-causing agents), and their widespread use only amplifies chemical hazards, adversely affecting human health. However, past research lacks comprehensive information regarding human health effects associated with long-term pesticide use. This study highlights the significant role that long-term research plays in identifying potential health concerns surrounding registered pesticides, especially as the Environmental Protection Agency (EPA) plans to reaffirm its decision to allow dicamba use on genetically engineered (GE) crops. Nathan Donley, Ph.D., a scientist with the environmental health program at the Center for Biological Diversity, comments: “This sweeping study exposes the terrible human cost of the EPA’s reckless decision to expand the use of dicamba. […]For the EPA to approve widespread use of this poison across much of the country without assuring its safety to people and the environment is an absolute indictment of the agency’s persistent practice of rubber-stamping dangerous pesticides.” Dicamba—a benzoic acid chemical that controls broadleaf weeds—is one of the most widely applied herbicides in corn production. As a result of weed resistant to […]

(Beyond Pesticides, May 14, 2020) Four banned organochlorine pesticides (OCP) are present in over 60% of a cohort of reproductive-age, black women in Detroit, according to a study published in Environmental Research by Boston University School of Public Health (BUSPH). OCPs are lipophilic (fat combining/dissolving), environmentally steadfast chemicals linked to harmful health effects. This study stresses the importance of monitoring pesticide accumulation, particularly regarding environmentally persistent chemicals and their metabolization via indirect exposure routes. Lead author Olivia Orta, Ph.D., a postdoctoral research associate in the Department of Epidemiology at BUSPH, highlights the significance of water monitoring—especially in light of historically disproportionately high hazards for people of color (e.g., Flint, Michigan)—and testing sources prone to OCP contamination. She remarks, “The sources that we identified as potential OCP correlates should be tested for pesticide contamination,[…] especially drinking water.” Environmental contaminants, like organochlorine pesticides (OCP), can persist in the environment decades after use stops, as OCPs have greater chemical stability and gradual attenuation. Minority populations are at higher exposure risk of environmental contaminants (i.e., pesticide) exposure that can catalyze adverse health and birth effects, especially in metropolitan areas. Although black women endure higher body burdens than other U.S. populations, there remains a lack of research surrounding the association. Boston University researchers enrolled […]

(Beyond Pesticides, November 1, 2019) The recently published report Pesticide Residue Monitoring Program Fiscal Year 2017 Pesticide Report, from the U.S. Food & Drug Administration (FDA), provides data on the levels of pesticide residues that show up on the foods U.S. consumers eat. The report adds fuel to public concern about contamination of the food supply, and to discussion in the scientific and advocacy communities about what is and is not safe for human health. It is also a sobering reminder of just how much chemical-intensive agriculture depends on pesticides, whether insecticides, herbicides, or fungicides. This FDA report has been prepared annually since 1987 and is based on the agency’s Pesticide Residue Monitoring Program, which evaluates both domestically produced and imported human food samples, including fruit, vegetable, and animal products. As the report notes, “Three federal government agencies share responsibility for the regulation and oversight of pesticide chemical residues in or on food. The U.S. Environmental Protection Agency (EPA) registers (i.e., approves) the use of pesticides and establishes tolerances for pesticide chemical residues in or on food resulting from the use of the pesticides. Tolerances are the EPA-established maximum residue levels (MRLs) of a specific pesticide chemical that is permitted in […]

(Beyond Pesticides, February 13, 2019) Friends of the Earth (FOE) released a report last week again showing pesticide residues in the food supply. The report, Toxic Secret, found store and name brand foods produced and sold by the top four U.S. food retailers — Kroger (NYSE:KR), Walmart (NYSE: WMT), Costco (NYSE:COST) and Albertsons — contain residues of toxic pesticides linked to a range of serious health and environmental problems. Among the pesticides found is the herbicide glyphosate, confirming residue testing results found in numerous studies. Glyphosate, the active ingredient in Roundup, has has been detected in popular foods, including “100% pure” honey, Doritos, Oreos, Goldfish, Ritz Crackers, German beers, California wines, and UK bread. Glyphosate has been ranked as potentially cancer causing in humans and adversely affects the human gut microbiome. See Residue Testing Find More Glyphosate in Popular Cereals. The FOE study finds that oat cereals, apples, applesauce, spinach and pinto beans at the retailers contained detectable amounts of glyphosate, organophosphates and neonicotinoids. The average level of glyphosate found in cereal samples (360 parts per billion) was more than twice the level set by scientists at Environmental Working Group for lifetime cancer risk for children. The average level of glyphosate found in pinto beans (509 ppb) was more […]

(Beyond Pesticides, November 30, 2018) A study published this month in Science of the Total Environment reveals numerous pesticide residues persisting in soil, harming the viability of agricultural lands and increasing risk of off-site contamination. Funded by the Horizon 2020 programme of the European Commission, researchers from the European Diverfarming project at the University of Wageningen in the Netherlands suggest nations urgently reevaluate conventional land use and inputs including water, energy, fertilizers, machinery and pesticides. Researchers decrying the lack of soil protection policies endeavored to determine which pesticides had the highest soil persistence and toxicity to non-target species. Three hundred seventeen surface soil samples were analyzed from 11 European countries. Selected countries were those with the largest amounts of active agricultural land, characterizing six distinct cropping systems. Sampled soils purposefully represented different soil properties and were taken from crops with the highest pesticide use per hectare. Samples were then analyzed for the concentration of 76 pesticide residues. These 76 pesticides were selected as being most often applied on conventional crops. Eighty-three percent of samples contained varying degrees of pesticide residues, with 25 percent showing one pesticide residue and 58 percent showing mixtures of two or more. Only 17 percent of […]

(Beyond Pesticides, November 21, 2018) A study published last month in the Journal of Apicultural Research finds significant numbers of U.S. honey bees at risk after exposure to hazardous synthetic pesticides intended to control mosquitoes. With many beekeepers rarely given warning of insecticide spraying, researchers say the risk of losing colonies could increase. Advocates say fear of Zika and other mosquito-borne illnesses could result in counterproductive and reactionary insecticide spraying that will add further stress to managed and native pollinators already undergoing significant declines. Researchers aimed to determine whether neighboring honey bee colonies could be similarly affected by aerial insecticide spraying. To calculate the percentage of colonies that could be affected, density of honey bee colonies by county was compared with projections of conditions thought to be prone to regional Zika virus outbreaks. Researchers found 13 percent of U.S. beekeepers at risk of losing colonies from Zika spraying. In addition, it was determined that many regions of the U.S. best suited for beekeeping are also those with favorable conditions for Zika-prone mosquitoes to proliferate. These regions include the southeast, the Gulf Coast, and California’s Central Valley. “[Considering] all the threats facing bees,” says study lead author Lewis Bartlett of the […]

(Beyond Pesticides, November 8, 2018) Two months after publishing its first series of tests, part two of an Environmental Working Group (EWG) study finds residues of Roundup’s active ingredient, glyphosate, in all General Mills’ Cheerios and PepsiCo’s Quaker Oats products sampled. Health advocates are expressing concern about the consequences of chronic glyphosate exposure, and say U.S. federal agencies must limit the herbicide’s use on oat-based breakfast foods regularly marketed to children. In addition, organic itself is under threat, as chemical-intensive management practices undermine the future of the growing organic movement. In this second round of testing, EWG scientists purchased products around San Francisco and Washington DC. 28 samples of conventional and 16 samples of organic oat products were collected. Approximately 300 grams of each General Mills and PepsiCo product were packaged and shipped to Anresco Laboratories, in San Francisco. Detected glyphosate residues were compared to EWG’s own health benchmark of 160 parts per billion (ppb). This benchmark is based on risks of lifetime exposure and what EWG scientists consider allowable and protective of children’s health with an adequate margin of safety. EWG’s results detected glyphosate residues in all 28 samples of conventionally grown oat products. The vast majority (all but two) […]

(Beyond Pesticides, August 28, 2018) Reinforcing findings of glyphosate residues in numerous food products, high levels of the herbicide is found in Cheerios and other popular oat-based food products, according to a study conducted by Environmental Working Group (EWG). The news comes at a time of increased public attention to the weed killer, following a landmark court case that resulted in a $289 million verdict for a school groundskeeper who presented evidence that regular glyphosate use caused him to develop cancer. Glyphosate, the active ingredient in Roundup, has been found in popular foods, as the prior research has found similar results, and the chemical has also been detected in “100% pure” honey, Doritos, Oreos, Goldfish, Ritz Crackers, German beers, California wines, and UK bread. Glyphosate has been ranked as potentially cancer causing in humans and adversely affects the human gut microbiome. EWG tested 45 different conventionally grown oat products, and 16 organic items. Results found glyphosate in nearly every conventional product, 43 out of 45, and 5 of the 16 organic products. However, conventional products generally contained much higher levels of glyphosate than those which were organic certified (typically caused by chemical drift from neighboring chemical-intensive farms and environmental contamination).
