Glyphosate Exposure Linked to Behavioral and Gut Health Concerns in New Studies

(Beyond Pesticides, November 15, 2023) A study previously published in the Federation of American Societies for Experimental Biology (FASEB) is drawing renewed attention to the gut microbiome in the scientific community. The study, involving a team including Demetrio Sierra-Mercado, PhD, of the University of Puerto Rico School of Medicine, initially established a link between glyphosate exposure and increased anxiety and fear-related behavior in rats. Glyphosate, a widely-used herbicide, has been detected in trace amounts in fruits, vegetables, grains, and other food and beverages, according to the U.S. Environmental Protection Agency (EPA). Originally deemed safe for humans due to the way it interacts with the shikimic acid pathway—a metabolic route that is absent in humans—glyphosate’s indirect effects on human health are now under scrutiny as the research linking it to anxiety-like behavior grows.  Dr. Sierra-Mercado’s team is expanding on his previous research to take a closer look at the compound’s potential disruption of the gut microbiome, which plays a pivotal role in regulating both physical and mental health. His upcoming study, anticipated in August 2024, aims to delve into the intricate relationship between glyphosate exposure and the gut-brain axis, with a focus on how this may influence neurological and emotional health […]

Pesticide-Intensive Agricultural Practices Lead to Elevated Childhood Cancer Rates in Brazil

(Beyond Pesticides, November 7, 2023) Two decades after the introduction of genetically engineered, herbicide-resistant crops and the consequential exponential growth in weed killers, Brazil is seeing an increase in childhood cancer. This is the conclusion reached in a comprehensive study spanning 15 years (2004-2019), “Agriculture Intensification and Childhood Cancer in Brazil,” published in Proceedings of the National Academy of Sciences (PNAS) in October. For the past 20 years, soybean herbicides have been killing and sickening children in the Cerrado and Amazon regions–where soybean cultivation is concentrated. The study reveals a link between an increase in soy cultivation and a spike in cases of acute lymphoblastic leukemia (ALL), the most common cancer affecting children, among indirectly exposed populations. Researchers identify pesticide-contaminated drinking water as the driving force behind the increased cancer rates occurring downstream from soybean sites.  In 2003, Brazil legalized its first official genetically modified (GM) crop, welcoming the era of GM soybeans and sparking a radical transformation in its agricultural landscape–for better or worse. The introduction of Monsanto’s Roundup Ready soybean seed promised farmers an efficient and herbicide-resistant alternative to traditional crops. A significant shift occurred in the areas dedicated to soy cultivation in the Cerrado region, tripling from […]

EPA Rejects Petition Seeking Review of Complete Ingredients in Pesticide Products

(Beyond Pesticides, October 16, 2023) After six years, the Environmental Protection Agency (EPA) finally responded to a citizen petition requesting that the agency evaluate complete formulations of pesticide products, not just the ingredients the manufacturer claims attack the target pest (so-called “active” ingredients). EPA’s response: No. Nowhere in EPA’s denial of the need for a more robust toxicological analysis is the problem more evident than in its refusal to require analyses of the so-called “inert ingredients” or “adjuvants” included in various formulations of pesticide products. The citizen petition [see more background] was followed by a lawsuit for the same purpose in 2022. Inerts and formulants are substances that enhance the distribution or adhesion of the active ingredient; adjuvants enhance the effectiveness of the active ingredient. These terms suggest that those chemicals have no effect on anything in the area where the pesticide is applied—a wildly inaccurate implication. At least as early as 1987, EPA had recognized that some inerts and adjuvants were “of toxicological concern,” yet it still requires very few toxicological tests of whole-formula pesticides or their purportedly inactive components. EPA responded to the petition as follows: “[T]he Agency appropriately assesses, as part of its review, the impacts to […]

Bayer’s Use of EU-Forbidden Pesticides Ignites Protest in South Africa 

(Beyond Pesticides, September 19, 2023) Farmworkers in Paarl, South Africa took to the streets on Friday, September 8, demanding an end to the indiscriminate importation and use of pesticides, herbicides, and fungicides containing substances prohibited by the European Union (EU). This protest is part of a broader global trend of outcry against systemic issues of environmental racism that disproportionately burden communities with environmental and health risks.   Organized by the Women on Farms Project, the protesters marched to the headquarters of Bayer. The German pharmaceutical, biotechnology, and pesticide company, responsible for producing and exporting agrochemicals known to be toxic to ecosystem and human health, has previously faced multiple lawsuits, including a multimillion-dollar one linking their glyphosate weed killer products (RoundupÂź) to non-Hodgkin Lymphoma. At the Bayer office, the protesters presented a memorandum demanding an end to the importation and use of EU-prohibited substances.    Protesters sought to expose the hypocritical tactics European agrochemical companies use to sell products in developing nations, even when those products are deemed unsafe in their home countries. Numerous farmworkers, like victim-turned-activist Antie Dina, spoke out about their health issues from petrochemical exposure. In her talk, Dina emphasizes that, “… enough is enough, we do not want any […]

Of Note During Organic Month, Study Finds Organic Diet and Location Affect Pesticide Residues in the Body

(Beyond Pesticides, September 7, 2023) During Organic Month, the importance of organic practices is brought into sharp focus by a study published in July in Environmental Health Perspectives, which emphasizes the importance of an organic diet and location to residues of pesticides in the body. The study finds urinary levels of the weed killer glyphosate significantly decrease through an organic diet for pregnant individuals living further than 0.5km (~1640ft) from an agricultural field. However, the study finds that adopting an organic diet among pregnant individuals living closer than 0.5km to an agricultural area does not significantly decrease glyphosate levels, indicating alternative sources of contamination outside of diet. Although past studies prove time and time again that an organic diet can reduce the levels of pesticides in the body, far too few studies investigate how the intervention of the organic diet can alter glyphosate levels among pregnant individuals living near or far from agricultural fields on which the herbicide is used. Furthermore, pesticides’ presence in the body affects human health, especially during vulnerable life stages like childhood, puberty, pregnancy, and old age. The study raises the complexity of fully tracking multiple exposures to glyphosate and other pesticides and the need for […]

“Legalized Poisoning of 5,500 People” Message Highlights Controversy Over Aerial Pesticide Spray in Oregon

(Beyond Pesticides, September 5, 2023) Lincoln County, Oregon  community members are fighting a plan announced by a private landowner to aerially spray 473 acres of clear-cut forest over the Beaver Creek watershed with a pesticide mixture containing carcinogenic glyphosate (commonly found in Roundup).  The aerial spraying is slated to take place approximately one mile from a water intake at Seal Rock Water District, which supplies water to 5,500 residents. Beyond the risks to human health, residents are concerned about the impacts on wildlife in the creek valley. Local advocates describe the area to include native wetland plants, birds, and fish, including the federally protected Coho Salmon and Marbled Murrelet, beaver, river otter, and roaming elk herds. Beavercreek is also a protected state natural area, where families paddle and walk along the state park marshlands.  Neighbors of Beaver Creek and the surrounding community are organizing phone banking, public art displays, and a petition urging Governor Tina Kotek to put a moratorium on the spray operation. One of the efforts displays the message “legalized poisoning of 5,500 people” through lights projected onto a basalt rock formation at Seal Rock State Park. The community has gathered over 2,000 petition signatures and over 100 […]

Study Finds Glyphosate Exposure Among the General Population Poses a Risk to Neurological Health

(Beyond Pesticides, August 31, 2023) A study published in Environmental Research finds glyphosate levels in the body adversely affect neurological health. Specifically, oral intake (e.g., eating contaminated foods), inhalation, and dermal exposure to glyphosate lowered cognitive function scores, heightened likelihood of severe depressive symptoms, and impaired auditory (hearing) function. Thus, this study provides some of the first evidence linking glyphosate exposure to specific neurological health outcomes among the general U.S. population, indicating the need for further studies on mechanisms driving neurotoxicity and the medical significance over time. Although this study is among the first to highlight specific neurological effects from glyphosate exposure among the general population, this study is not the first to identify potential neurotoxicity from glyphosate exposure. (Previous research cited below.) The ubiquity of glyphosate uses in agriculture—which leaves residues of the toxic chemical in food—and in public areas (e.g., parks, and walkways) may mean that exposures to it represent a significant risk factor for the disease. Glyphosate is already implicated or proven in developing numerous health anomalies, including cancer. The neurological system, including the brain, spinal cord, and a vast network of nerves and neurons, is responsible for many bodily functions—from sensation to movement. However, pesticides play various roles in […]

Study Cites Multiple Chemical Characteristics, Strengthening Weed Killer Glyphosate Cancer Ranking

(Beyond Pesticides, August 11, 2023) Reinforcing earlier findings, a systematic review published in Chemosphere finds the popular herbicide glyphosate and its formulations (glyphosate-based formulations-GBF) exhibit five out of the ten key characteristics (KC) of carcinogens (cancer-causing chemicals). Specifically, glyphosate exhibits strong evidence of genotoxicity, epigenetic alterations (heritable changes in gene expression), oxidative stress, chronic inflammation, endocrine disruption, and disturbs gut microbiota implicated in lymphomagenesis (growth and development of lymphoma). Although organizations like the International Agency for Research on Cancer (IARC) designate glyphosate as a probable human carcinogen, and scientific literature supports the findings on these adverse effects purported by glyphosate, the chemical remains on the U.S. market in various formulations. Glyphosate is the most commonly used active ingredient worldwide, appearing in many herbicide formulas, not just Bayer’s (formerly Monsanto) RoundupÂź. The use of this chemical has been increasing since the inception of crops genetically modified to tolerate glyphosate over two decades ago. The toxic herbicide readily contaminates the ecosystem with residues pervasive in food and water commodities. In addition to this study, literature proves time and time again that glyphosate has an association with cancer development, as well as human, biotic, and ecosystem harm. Therefore, advocates point to the need for national policies to reassess hazards associated with […]

Zebrafish Study Links Glyphosate Exposure to Heart Damage Through Aging and Reduced Creation of Cardiac Muscle Cells

(Beyond Pesticides, June 30, 2023) Exposure to environmentally relevant concentrations of the herbicide glyphosate (GLY) has the potential to induce heart damage (cardiotoxicity) through the aging (senescence) of cells and a reduction of the number of rapidly increasing (proliferating) cells, according to a study published in Ecotoxicology and Environmental Safety. Specifically, glyphosate induces toxic effects on cardiomyocytes (cardiac muscles) responsible for contractions that pump the blood. Cardiovascular (heart) disease (CVD) is one of the leading causes of death in the U.S., with approximately 700,000 people dying annually of heart disease, equating to 25% of all U.S. deaths. Additionally, heart conditions are one leading cause of disability in the U.S. Research has shown that environmental pollutant exposure can increase the risk of developing cardiovascular disease, including stroke, heart attack, heart failure, atrial fibrillation, and cardiac arrest. Considering chemical exposure exacerbates adverse disease effects, reviews like these highlight the significance of evaluating synergism between diseases and toxic chemicals to safeguard human health. The study warns, “Our findings offer important information regarding the potential mechanisms of GLY cardiotoxicity toxicity. Notably, our study provides new insights into the relationship between GLY and senescence. Cardiac dysfunction of GLY to non-target organisms need to be noted in future study. Our study raises concerns about the […]

Study Elevates the Connection Between Pesticides, the Gut-Brain Axis, and Disease

(Beyond Pesticides, June 27, 2023) Pesticides interfere with biological processes. This is their purpose. Unfortunately, they nearly always have unintended consequences, many of which have been ignored by their manufacturers. A new review article by Irish and Dutch researchers in the ISME Journal adds to the emerging scientific literature examining how pesticides affect the relationship between the human gut and the human brain (the “gut-brain axis”). Often called the “second brain” because it houses nerve cells and produces neurotransmitters, the gut-brain axis may be the most important locus where microbes and pesticides meet. The human gut plays host to a variety of microorganisms, ranging from bacteria and archaea to fungi, viruses and yeasts.[1] In a healthy person these microbes remain in balance and often cooperate both with each other and with human cells. The gut and the brain are deeply integrated through the vagus nerve and the neuroendocrine system. The vagus nerve is a treelike bundle of fibers extending from the lower part of the brain to nearly every body organ, but particularly the heart, lungs and digestive tract. The neuroendocrine system comprises specialized cells inhabiting nearly all the organs of the body that respond to signals from the brain […]

EU and U.S. Pesticide Regulators Ignore Developmental Neurotoxicity of Pesticides, Industry Hides Data

(Beyond Pesticides, June 9, 2023) Glyphosate, usually marketed as the herbicide Roundup, has long been the poster child for shoddy regulation by both the U.S. Environmental Protection Agency (EPA) and the European Food Safety Authority (EFSA). In a study published June 1, 2023 in Environmental Health by Axel Mie and Christina RudĂ©n, PhD, of Stockholm University and the Centre for Organic Food and Farming in Uppsala, the authors followed up on earlier work that documented deficiencies in information provided to European Union (EU) regulators by manufacturers. They identified nine studies on developmental neurotoxicity (DNT) that had been submitted to the U.S. Environmental Protection Agency (EPA) but were not disclosed to EU authorities. According to the research, seven of these studies would have “actual or potential regulatory impact.” According to the authors: “Of the nine undisclosed DNT studies, three were sponsored by Bayer and performed in their own laboratory. Three studies were sponsored by Syngenta and performed in their Central Toxicology Laboratory. One study each was sponsored by Nissan Chemicals and Ishihara Sangyo Kaisha (ISK), and these were performed at Huntingdon Life Sciences. For the remaining study, the sponsor and laboratory are unknown to us.” This study is a new example […]

Corporations Are Asked to Stand Up for Health and the Environment; Sell Organic Compatible Products

(Beyond Pesticides, March 27, 2023) In a move labeled “risk mitigation”—that is, mitigation of the risk to its shareholders—Bayer-Monsanto announced in 2021 that it would phase out Roundup™ products containing glyphosate for the residential lawn and garden market as of January 2023. In taking this action, Bayer-Monsanto is making no admissions, and glyphosate products will still be available to farmers. However, Lowe’s and Home Depot are still selling the glyphosate-based lawn and garden products. Tell Lowe’s and Home Depot to eliminate Roundup™ and other toxic pesticides, promote organic practices, and sell organic compatible products.  In fact, since this is a voluntary reformulation, and Bayer-Monsanto has decided its own timing, the company cannot be held accountable to anything. The company could change its mind, and stores can continue to sell the glyphosate-based products as long as they want. And keep in mind that replacement versions of Roundup™ products are also toxic. RoundupÂź Dual Action, for example, contains the following active ingredients: triethylamine salt of triclopyr, fluazipop-P-butyl, diquat dibromide, and ammonium salt of imazapic. Thus, Bayer/Monsanto announces that it is changing the formulation of Roundup and moving away from glyphosate, while continuing to sell Roundup™ products formulated both with and without glyphosate—leaving consumers unaware of their risks. The U.S. Environmental Protection Agency (EPA) has […]

Glyphosate Exposure Associated with Liver and Metabolic Disorders in Children, Young Adults

(Beyond Pesticides, March 7, 2023) Exposure to glyphosate (Roundup) and its breakdown products is associated with an increased risk of liver and metabolic disorders in children and young adults, according to research published in Environmental Health Perspectives earlier this month. While glyphosate has developed a well-deserved reputation as a carcinogen, research is finding that cancer is one of a myriad of chronic diseases associated with the notorious chemical. As this body of literature grows, growing awareness by the public is increasing pressure on the U.S. Environmental Protection Agency to cancel its allowed uses. Researchers began their investigation concerned about the rise of liver disorders and metabolic syndrome among young people. This trend has been pronounced among populations of color. The worrying increase has led many to consider synthetic chemical exposure as a contributing factor, as lack of diet and exercise is unlikely to account for the entirety of the increase. To better understand these impacts, researchers enrolled existing participants in the CHAMACOS (Center for the Health Assessment of Mothers and Children of Salinas) study, a long running cohort of mothers and their children born between the years 2000 and 2002 in the Salinas Valley of California. Enrolled participants consistent mostly […]

Glyphosate Weed Killers Reduce Crop Yields and Hamper Climate Mitigation Efforts

(Beyond Pesticides, February 15, 2023) Glyphosate use in grassland pastures reduces crop yield and impedes climate change mitigation, finds two studies (1,2) published this month from the University of Turku, Finland. While massive public relations campaigns by the agrichemical industry have poured in millions of dollars to convince politicians and the public that pesticides are necessary to ‘feed the world’ and address the climate crisis, the data does not support these claims. “Only in recent years, we have started to realise that intensive agriculture and agrochemical pollution in fact contribute to a reversal of the intended purpose. Soils are polluted with pesticides and at the same time, extreme weather events erode soil nutrients,” says study coauthor Benjamin Fuchs, PhD. Researchers approached their investigation through two separate experiments on the grass Festuca pratensis, an important forage crop grown for grazing animals throughout the world. The first experiment was conducted in an enclosed greenhouse, while the second took place in a field setting. For both experiments, plots were separated between glyphosate-sprayed and unsprayed controls. All plots received three different approaches to cutting the grass: one group that was intensely cut to two inches (5cm), the second group cut to six inches (15cm), […]

Garden Pesticide Use Harms Local Bird Populations, Study Authors Say “We Should Simply Ban These Poisons”

(Beyond Pesticides, February 8, 2023) Spraying pesticides around one’s garden negatively impacts local bird populations, according to research published by scientists at the University of Sussex, UK in Science of the Total Environment. Although this reasoning sounds common sense to those versed in the works of Rachel Carson, it underscores the immense importance of carrying on the legacy of her work and continuing to educate the public about the ongoing dangers posed by modern pesticides. As the study authors write, “Overall, our study shows that garden bird abundance and richness is strongly influenced by both extrinsic and intrinsic factors, and suggests that garden management, particularly regarding pesticide use, has a significant effect on bird life.” Researchers collected data by partnering with the British Trust for Ornithology, which conducts annual citizen-science counts of bird populations in UK gardens. Nearly 24,000 residents participate in the survey, which also includes information about the urbanization level surrounding their gardens, and other habitat characteristics. A group of these volunteers were provided with a questionnaire about their pesticide practices between 2020-2021, recording information on how often the pesticides were applied, as well as the pesticide brand name. After removing incomplete or unusable data, 615 individual gardens […]

Glyphosate Induces Oxidative Stress, A Cancer Precursor, According to NIH Study

(Beyond Pesticides, January 31, 2023) Glyphosate exposure induces oxidative stress in the body, a key biomarker known to heighten an individual’s risk of cancer, according to research published in the Journal of the National Cancer Institute by a team of scientists from the National Institutes of Health. The findings, which tracked study participants’ past use of glyphosate and exposure levels through urine, are particularly concerning in light of recent data showing that four out of five (81.6%) U.S. residents have detectable levels of glyphosate in their bodies. Despite these concerning data, evidence of widespread exposure to a carcinogen has so far failed to sway regulators at the U.S. Environmental Protection Agency, necessitating meaningful change by elected officials to reform pesticide regulation. Scientists began with the determination from the International Agency for Research on Cancer (IARC) that there is epidemiological evidence associating glyphosate with blood cancers like non-Hodgkin lymphoma, and strong evidence of carcinogenicity in laboratory animal research brought on by genotoxicity (DNA damage) and oxidative stress. “Oxidative stress occurs when the production of reactive oxygen species (ROS) and other free radicals exceeds the body’s antioxidant defense mechanisms, causing damage to DNA, proteins, and lipids,” the study explains. This process can […]

Denying Science, Manufacturing Doubt: Monsanto/Bayer’s Promotion and Defense of Glyphosate/Roundup

(Beyond Pesticides, December 16, 2022) A report released last week — Merchants of Poison: How Monsanto Sold the World on a Toxic Pesticide — exposes not only Bayer/Monsanto malfeasance in its “promotion” of its glyphosate-based herbicide products, including the notorious RoundupÂź, but also, the broader landscape of corporate efforts to white- or green-wash products that companies know are harmful to people and the environment. The report was issued by U.S. Right to Know (USRTK, a nonprofit investigative research group focused on promoting transparency for public health), Friends of the Earth (FOE), and Real Food Media. It carries the pithy subtitle, “A case study in disinformation, corrupted science, and manufactured doubt about glyphosate,” a description cited by the Friends of the Earth press release as “at the core of the pesticide industry’s public relations playbook.” Beyond Pesticides welcomes this report, which comports with much of our previous coverage of the pesticide industry’s egregious misbehavior, and of glyphosate, the world’s most widely used herbicide. FOE calls the report the “first comprehensive review” of the Bayer/Monsanto “defense strategy” employed in attempts to deny science, manufacture doubt, and discredit critics who have researched, reported on, and/or advocated against the company’s flagship glyphosate products because […]

Hormone Mimicking Properties of Glyphosate Weed Killer and Related Compounds Increase Breast Cancer Risk

(Beyond Pesticides, November 25, 2022) A study published in Chemosphere adds to the growing body of research demonstrating the endocrine (hormone) disrupting effects of glyphosate play in breast cancer development. Exposure to the herbicide glyphosate and other glyphosate-based herbicides (GBHs) at high concentrations mimics the estrogen-like cellular effects of 17ÎČ-estradiol (E2), altering binding activity to estrogen receptor α (ERα) sites, thus causing fundamental changes in breast cancer cell proliferation (abundance).  Glyphosate is the most commonly used active ingredient worldwide, appearing in many herbicide formulas, not just Bayer’s (formerly Monsanto) RoundupÂź. The use of this chemical has been increasing since the inception of crops genetically modified to tolerate glyphosate over two decades ago. The toxic herbicide readily contaminates the ecosystem with residues pervasive in food and water commodities. In addition to this study, literature proves time and time again that glyphosate has an association with cancer development, as well as human, biotic, and ecosystem harm. Therefore, advocates point to the need for national policies to reassess hazards associated with disease development and diagnosis upon exposure to chemical pollutants. The researchers note, “The results obtained in this study are of toxicological relevance since they indicate that glyphosate could be a potential endocrine disruptor in the mammalian system. Additionally, […]

EPA’s Deficient Pesticide Analysis Contributes to Ecological Decline

(Beyond Pesticides, November 21, 2022) Once again, the Environmental Protection Agency (EPA) has registered a new pesticide without performing a thorough review of its impacts on biodiversity as well as threatened and endangered species. Inpyrfluxam was registered in 2020 and only after being sued by the Center for Biological Diversity for failure to comply with the Endangered Species Act (ESA) did EPA commit to completing draft effects determinations by Fall 2022. Once again, EPA’s draft biological evaluation is incomplete and inadequate. EPA is accepting comments on its draft biological evaluation at Regulations.gov.  Tell EPA and Congress that Pesticide Registrations Require Complete Science. The Review of Inpyrfluxam is Incomplete and Inadequate.  The agency’s draft effects assessment is flawed and incomplete. We share the details because it shows that EPA is out of step with the science and its regulatory responsibility when it comes a thorough review for ecosystem effects of pesticides.   The agency used fish early life stage (ELS) tests to estimate chronic fish toxicity. This is inappropriate. The fish ELS is a sub-chronic test of sensitive life stages. Although it is often used as a surrogate or predictor of chronic toxicity, it does not adequately address potential adverse effects on reproduction or transfer of the test chemical to eggs/offspring […]

Weed Killer Use Destroys Soil Life and Ecosystems, Paper Finds

(Beyond Pesticides, November 11, 2022) A paper published in Trends in Ecology & Evolution in late October sounds an unnerving alarm about the globally ubiquitous use of herbicides and the ecological destruction being caused. It asserts that widespread environmental contamination with these herbicide compounds is influencing soil, plant, and animal microbiomes in ways that are not only not well understood, but also, can have significant impacts on the functioning of organisms and their ecosystems — with evolutionary implications. Impacts of herbicides on microbiota in soils include, for example, those on nutrient cycling, and altered organism and plant performance, which can affect pollination and animal consumption of plants. This research reinforces what Beyond Pesticides wrote in covering a 2021 study: “The popular herbicide glyphosate negatively affects microbial communities, indirectly influencing plant, animal, and human health. Exposure to sublethal concentrations of glyphosate shifts microbial community composition, destroying beneficial microorganisms while preserving pathogenic organisms.” Herbicides are a category of pesticide used to control weeds in agriculture and commercial forests, on managed landscapes, byways, gardens, and lawns, and directly on surface waters to control aquatic weeds. They are designed to kill “target” plant species considered undesirable in any of those circumstances. Herbicide use has exploded […]

Glyphosate Induces Antibiotic Resistance in Deadly Hospital-Acquired Infection

(Beyond Pesticides, November 8, 2022) Glyphosate weed killers induce antibiotic resistance in deadly hospital-acquired bacteria, according to a new study published late last month in the journal Scientific Reports. This is the latest finding connecting commonly used herbicides to the rise of antibiotic resistant bacteria, with prior research showing glyphosate, 2,4-D, and dicamba able to create resistance in Salmonella and E. coli. While federal regulatory agencies continue ignore the role of pesticides in the development of antibiotic resistance, it is critical for states and localities to take action to protect their most vulnerable both from toxic exposure to these herbicides and the multitude of indirect effects caused by their use. This is all happening as antibiotic resistance is rising to dangerously high levels in all parts of the world, according to the World Health Organization. In the May 1, 2022 issues of the Bulletin of the World Health Organization, Samira Choudhury, PhD, et al. writes, “Often referred to as the silent pandemic, antimicrobial resistance claims the lives of over 700,000 people annually.” The authors continue, “A study suggests that if no actions are taken, antimicrobial resistance will cause 10 million deaths per year by 2050 and an economic impact of […]

Glyphosate Based Herbicides and Bee Health: The American Bumble Bee

(Beyond Pesticide, October 20,2022) Exposure to environmentally relevant levels of glyphosate-based herbicides (GBHs) weakens bumblebees’ (Bombus Terrestris) ability to distinguish between colors or fine-color discrimination. According to research published in Science of The Total Environment, a lack of fine-color discrimination skills can threaten bumble bee survivability through impact on colony fitness and individual foraging success. Much research attributes the decline of insect pollinators (e.g., commercial and wild bees and monarch butterflies) over the last several decades to the interaction of multiple environmental stressors, from climate change to pesticide use, disease, habitat destruction, and other factors. In the U.S., an increasing number of pollinators, including the American bumblebee and monarch butterfly, are being added or in consideration for listing under the Endangered Species Act, with specific chemical classes like systemic neonicotinoid insecticides putting 89% or more of U.S. endangered species at risk. Pollinator decline directly affects the environment, society, and the economy. Without pollinators, many plant species, both agricultural and nonagricultural, will decline or cease to exist as U.S. pollinator declines, particularly among native wild bees, limits crop yields. In turn, the economy will take a hit, as much of the economy (65%) depends upon the strength of the agricultural sector. As science shows, pesticides are one of the most significant stressors […]

Chemical Alterations in the Body from Glyphosate-Based Herbicide During Perinatal Exposure Induces Chronic Liver Injury

(Beyond Pesticides, October 13, 2022) Offspring’s exposure to glyphosate-based herbicides (GBHs) preceding and proceeding birth (perinatal) induces liver damage. A study published in Toxicology and Applied Pharmacology demonstrates the role excess iron in the body from GBH exposure plays in liver toxicity via an increased uptake of calcium and oxidative stress. The liver, the largest solid organ in the human body, is an essential part of the digestive system, responsible for blood detoxification, nutrient metabolization, and immune function regulation. The rates of chronic liver diseases are increasing, representing the second leading cause of mortality among all digestive diseases in the U.S. Because GBHs are ubiquitous in many herbicide products, studies report that these toxic chemical compounds are detectable in infants, children, and pregnant women. Children are particularly vulnerable to the impacts of pesticide exposure as their developing bodies cannot adequately combat exposure effects. Although studies show how chemical exposures affect overall human health, more research is now questioning how these toxic chemicals influence digestive health and the subsequent occurrence of diseases. Therefore, it is essential to understand how harmful chemical exposure impacts health and well-being during critical developmental periods. The study notes, “[T]he possible role played by perinatal exposure to GBH […]
