(Beyond Pesticides, April 15, 2020) Home pesticide use during pregnancy is associated with an increased risk of a child developing the kidney cancer nephroblastoma, or Wilms’ tumor, according to research published in Cancer Epidemiology by a team of French scientists. Wilms’ tumor is one of the most common childhood cancers but has an inscrutable etiology. This study adds weight to the theory that pesticides are a driver of the tumor’s development, as pesticide use was more strongly associated than other widely investigated causes, including parental smoking and alcohol consumption during pregnancy. Families enrolled in an ongoing nationwide French study were questioned by phone about their lifestyle, including smoking habits, mother’s alcohol consumption, and household pesticide use. Participants were further segmented by their frequency of these risk factors, and pesticide use was narrowed down by type, including herbicide, fungicide, and insecticide use, as well as where the chemicals were used (indoor/outdoor). Researchers ultimately enrolled 117 families whose children developed nephroblastoma, and included 1100 families as a control. A regression analysis found no association between either parent smoking and incidence of the disease. Similarly, no pattern was found in the relation between maternal alcohol consumption and Wilms’ tumor. However, use of any […]

(Beyond Pesticides, April 7, 2020) Last week, the U.S. Environmental Protection Agency (EPA) registered a carcinogenic herbicide for new uses without following  the required public notification and comment process, the Midwest Center for Investigative Reporting (MCIR) reports. The chemical in question, isoxaflutole, is a broadleaf weedkiller that can now be applied to genetically engineered (GE) soybeans in half of U.S. states. Health and environmental groups are outraged by EPA’s furtive move, accusing the agency of colluding with the pesticide industry. “Clearly no one from the public health community knew about this because no one commented,” said Nathan Donley, PhD, of the Center for Biological Diversity to MCIR. “Yet there was all these industry comments, all these positive comments. Someone was tipped off that this docket had been opened. One side was able to comment, the other wasn’t.” Without public notification, only 54 comments were received. In its decision document, the agency touted how most of the input “were generally in favor of the decision to register the new use.” When questioned about its move, EPA simply told MCIR that it “requested public comment on the proposed registration decision.” The Federal Register provides the public notice of a proposed rulemaking by […]

(Beyond Pesticides, March 23, 2020) Ignoring science to side with Monsanto/Bayer, EPA has repeatedly failed to assess glyphosate’s impacts on public health and endangered species. Last week, a broad coalition of farmworkers, farmers, and conservationists, filed a federal lawsuit against the Environmental Protection Agency (EPA) over its January 2020 re-approval of the pesticide glyphosate, best known as the active ingredient in Monsanto’s Roundup pesticides. With Center for Food Safety (CFS) serving as legal counsel, the suing organizations are  Beyond Pesticides, the Rural Coalition, Organización en California de Lideres Campesinas, and the Farmworker Association of Florida. While EPA defends glyphosate, juries in several cases have found it to cause cancer, ruling in favor of those impacted by exposure. Glyphosate formulations like Roundup are also well-established as having numerous damaging environmental impacts. After a registration review process spanning over a decade, EPA allowed the continued marketing of the pesticide despite the agency’s failure to fully assess glyphosate’s hormone-disrupting potential or its effects on threatened and endangered species. The review began in 2009, has already taken 11 years, without a full assessment of the widespread harmful impacts on people and the environment in that time period. “EPA’s half-completed, biased, and unlawful approval sacrifices the […]

(Beyond Pesticides, March 3, 2020) Pregnant mothers living in areas where carcinogenic pesticides have been used are at increased risk of their child developing an acute form of leukemia, according to research published last month in the International Journal of Hygiene and Environmental Health by researchers at the University of California, Los Angeles. The findings are based on a review of pesticide use data in rural, agricultural areas of California, where many minority, low-income and farmworking communities live. Under current laws, the U.S. Environmental Protection Agency (EPA) permits the use of cancer-causing pesticides with an expectation that a certain number of cancers (anywhere from 1 in 1,000 to 1 in 1,000,000, based on the pesticide in question) should be considered ‘acceptable risk.’ While past studies have shown similar connections between pesticide exposure in the womb and the development of childhood cancer, this is one of the first to utilize geographic information systems (GIS) data, rather than parental interviews on past exposures. Researchers used California public records of cancer incidence from 1998-2011, alongside statewide pesticide use reports (California is the only state to make this information publicly accessible and searchable). A list of 65 pesticides were investigated for their specific connection […]

(Beyond Pesticides, January 27, 2020) United States military veterans suffering from bladder cancer, hypothyroidism, hypertension, and Parkinson’s-like symptoms after their exposure to Agent Orange will remain unprotected and uncompensated until at least late 2020, according to a letter sent by Veterans Affairs (VA) Secretary Robert Wilkie to U.S. Senator Jon Tester (D-MT). Send a letter to Veterans Affairs (VA) Secretary Robert Wilkie insisting that bladder cancer, hypothyroidism, hypertension, and Parkinson’s-like symptoms be added to the VA’s list of eligible conditions. Congress included a provision in the must-pass December federal spending bill requiring VA to provide legislators “a detailed explanation” for the now multi-year delay in determining whether to list the diseases. The provision is intended to cut through the ongoing delays, but there is no indication VA is going to meet the 30-day deadline. “The longer VA continues to drag its feet on expanding the list of conditions associated with Agent Orange, the longer our veterans continue to suffer—and die—as a result of their exposure,” Senator Tester said in a statement to the news site Connecting Vets. He continued, “It’s time for VA to stop ignoring the overwhelming evidence put forth by scientists, medical experts and veterans and do right by those who served. Any […]

(Beyond Pesticides, January 10, 2020) A new study by researchers out of the University of Iowa College of Public Health, published in JAMA (the Journal of the American Medical Association) Internal Medicine, demonstrates that greater exposure to pyrethroid insecticides is associated with higher risks of death from all causes and from cardiovascular disease. These compounds can be inhaled, ingested, or absorbed through the skin; they are highly neurotoxic, and have also been linked to certain cancers, endocrine disruption, and suppression of the immune system, as well as respiratory and reproductive impacts. The researchers gathered data, for 2,116 adults aged 20 or older, from the National Health and Nutrition Examination Survey. Each of those subjects had contributed a urine sample at some point between 1999 and 2002. Urine samples reflect levels of a pyrethroid metabolite (3-phenoxybenzoic acid) present, which in turn offer information about pyrethroid exposure. The researchers followed the participants until 2015; the research analysis was performed in the summer of 2019. Data were adjusted to accommodate multiple factors (age, sex, ethnicity, socioeconomic status, diet and lifestyle, smoking status, body mass index, and urinary creatinine levels). The co-authors report that subjects with the highest levels of metabolites had a 56% […]

(Beyond Pesticides, January 9, 2020) United States military veterans suffering from bladder cancer, hypothyroidism, hypertension and Parkinson’s-like symptoms after their exposure to Agent Orange will remain unprotected and uncompensated until at least late 2020, a letter sent by Veterans Affairs (VA) Secretary Robert Wilkie to U.S. Senator Jon Tester (D-MT) indicates. Congress included a provision in the must-pass December federal spending bill requiring VA to provide legislators “a detailed explanation” for the now multi-year delay in determining whether to list the diseases. This is seen by advocates for veterans as a serious lack of support and compensation just at a time when the current administration mobilizes the military. According to Military Times, 83,000 veterans suffer from bladder cancer, Parkinson’s-like symptoms or hypothyroidism, and an untold number have high blood pressure. The paper interviewed Army Sgt. Maj. John Mennitto, who explained, “Since we first spoke in 2016, I have been diagnosed with bladder cancer. . . I also have hypothyroidism. My greatest concern for me and my fellow veterans who have debilitating diseases caused by exposure to Agent Orange is that our family members will be left with nothing.” A robust 2014 review by the National Academy of Medicine recommended including […]

(Beyond Pesticides, November 5, 2019) Herbicide use is associated with an increased risk of developing cutaneous melanoma, a skin cancer, according to a meta-analysis published last month in the Journal of the European Academy of Dermatology and Venereology. For those working on farms and in other occupations with frequent exposure to herbicides, the risk is another in a long list of pesticide-induced diseases. Ultimately, researchers suggest, “A precautionary public health safety policy that includes preventive individual counselling and surveillance to workers exposed to pesticides may be advisable.” Authors of the study conducted a systematic review of the peer-reviewed literature on pesticide exposure and skin cancer, finding nine acceptable studies for analysis. These studies represent nearly 185,000 individuals, and included enough data to make a risk estimate and determine 95% confidence intervals. Although pesticides and insecticides in general were not associated with increased risk of skin cancer, general use of herbicides was (relative risk 1.85; 95% confidence interval, 1.01-3.36). Spouses whose partners work as pesticide applicators are also found to be at higher risk of developing cutaneous melanoma. As skin cancer has increased significantly over the past 50 years, many appropriately point to the link between sun exposure and development of […]

(Beyond Pesticides, September 11, 2019) Germany is the latest entity to take action on getting glyphosate-based pesticides out of the marketplace. Chancellor Angela Merkel has announced that, beginning in 2020, the country will phase out herbicides that contain glyphosate by the end of 2023. The phase-out will occur through a series of scheduled reductions in amounts allowed for use, with a goal of a 75% reduction over the next four years. The announcement comes after “nation-wide protests and demands from [Merkel’s] junior coalition partner, the Social Democrats, for more decisive action on environmental issues.” This action stands in telling contrast to the U.S. Environmental Protection Agency’s (EPA’s) repeated failures to protect people, ecosystems, and our food supply, from this toxic compound. The German government also plans to oppose any European Union (EU) request for renewal of licensing of these herbicides, according to the environment ministry. Bayer AG, maker of glyphosate-based herbicides and owner of original manufacturer Monsanto, has pushed back, saying that the government is “getting ahead of itself” by banning glyphosate-based herbicides prior to any decision by the relevant EU authority, and that EU laws disallow unilateral decisions by member states. (Pesticide licensing decisions lie with EU governance in Brussels, […]

(Beyond Pesticides, September 4, 2019) Sixteen organizations representing health, environmental, farmer, and farmworker communities joined together yesterday to call on EPA to remove glyphosate from the marketplace. The groups cite a combination of high-profile lawsuits, environmental impacts, increasing reports of weed resistance, and growing public concern over the health effects of glyphosate in their comments on EPA’s interim reregistration review decision for the chemical. The comments warn that EPA is at risk of damaging the public’s trust in the agency’s review process for toxic pesticides. “EPA’s myopic review and response to the dangers posed by glyphosate does a disservice to American farmers, farmworkers, and commercial landscapers wishing to use least-toxic products that do not put them at risk of health impacts, and consumers aiming to make the safest choice in regards to what to feed their family and how to manage their yards,” the comments read. The document likewise replies to EPA’s attacks against the World Health Organization’s International Agency for Research on Cancer (IARC), which determined glyphosate to be a probable carcinogen based on sufficient evidence of carcinogenicity in experimental organisms. EPA has indicated that its process for evaluating glyphosate, “…is more transparent than IARC’s process” and that IARC’s […]

(Beyond Pesticides, August 13, 2019) The U.S. Environmental Protection Agency (EPA) is refusing to approve product labels that disclose that the herbicide glyphosate may cause cancer, according to a press release published last week. The move comes after the state of California listed glyphosate on its Prop 65 list of chemicals known to cause cancer, birth defects or other reproductive harm. Health advocates are condemning the decision as the latest in a long string of EPA actions aimed at benefiting industry at the expense of consumer and public health. Many are concerned that the incessant stream of industry-friendly decisions is eroding public trust in the agency and its ability to act as an independent regulator. While a state judge gave the Prop 65 warning labels the go-ahead, a prior ruling from U.S. District Court Judge William Shubb in Sacramento placed a preliminary injunction on the California requirement that remains in place today. The state added glyphosate to its Prop 65 list after the International Agency for Research on Cancer (IARC) designated the chemical as a group 2A carcinogen.  Under Prop 65, California regulators are required to provide “clear and reasonable” warning labels when any one of four requirements in the […]

(Beyond Pesticides, June 4, 2019) A class-action lawsuit is accusing Starbucks stores in New York of misusing a highly toxic, carcinogenic pesticide near food, putting the health of customers and employees at risk.  “Stores throughout Manhattan have for many years been permeated with a toxic pesticide called Dichlorvos [DDVP], which is highly poisonous and completely unfit for use in proximity to food, beverages and people,” the suit reads. According to the lawsuit, Hot Shot brand No Pest Strips were placed in food areas in violation of labels that prohibit the pesticide’s use in “the food/feed areas of food/feed processing or food/feed manufacturing or food/feed service establishments.” A pest control operator found the illegally placed products on a number of separate occasions, hidden under bagels or in pastry display cases, during a five year period from 2013 to 2018. This was not at only one location, but appeared to be a common occurrence at nearly every one of the 100+ stores serviced by the pest control operator. The case brings to light a number of issues with the use of synthetic pesticides. The unsanitary conditions permitted to persist within Starbucks stores, per the pictures provided in the suit (see page 14), […]

(Beyond Pesticides, May 9, 2019) On Wednesday, the U.S. Environmental Protection Agency (EPA) issued a proposed interim decision on glyphosate’s registration review, ignoring widespread scientific consensus on the herbicide’s carcinogenicity and instead restating the agency’s firm position that glyphosate is “not likely to be carcinogenic to humans.” EPA’s bold statement stands in stark contrast to scientific consensus to the contrary. In 2015, the World Health Organization’s International Agency for Research on Cancer (IARC) found glyphosate to be a probable human carcinogen. In response to resistance from the European Food Safety Authority, 94 expert scientists published an article in support of IARC’s methodologies and findings. Since 2015, several more publications have added significant weight to the body of evidence supporting glyphosate’s carcinogenicity. A February 2018 meta-analysis of studies on glyphosate suggested “a compelling link between exposures to GBH [glyphosate-based herbicides] and increased risk of NHL [non-Hodgkin lymphoma]. A February 2019 University of Washington study found that glyphosate increased the risk of non-Hodgkin lymphoma by as much as 41%. Despite attempts by current and former EPA top officials to “kill” their report, Agency for Toxic Substances and Disease Registry (ATSDR), a agency at the U.S. Department of Health and Human Services, released its […]

(Beyond Pesticides, May 2, 2019) Researchers have documented an increase in food and drinking water residues of neonicotinoids, insecticides linked to breast cancer. Using the Pesticide Data Program (PDP), 1999-2015, of the U.S. Department of Agriculture, the researchers identified near-peak detection frequencies in 2015, after a decline from 2008-2013. Imidacloprid remains the most common neonicotinoid detected across imported commodities, while the neonicotinoids clothianidin, thiamethoxam, acetamiprid, and flonicamid are replacing imidacloprid in domestic production. Authors note that these newer neonicotinoids are potentially more toxic than imidacloprid, raising concerns for understudied human health and environmental impacts. The study, Trends in neonicotinoid pesticide residues in food and water in the United States, 1999–2015, published in the journal Environmental Health, finds the highest detection frequencies for neonicotinoids in drinking water, with 30% of treated drinking water turning out positive for imidacloprid in 2011. Certain fruits and vegetables are also frequently contaminated by neonicotinoids, with detection frequencies ranging from 20% to as high as 57% in the case of imidacloprid on cauliflower. While the study points to specific fruits and vegetables as posing higher risk, the main message reaches beyond individual commodity or individual neonicotinoid results. Authors uncover a systematic increase in detection of neonicotinoid […]

(Beyond Pesticides, March 20, 2019) In a second verdict against Bayer/Monsanto yesterday, a jury found unanimously that a California man’s non Hodgkin lymphoma (NHL) was substantially caused by the herbicide glyphosate (Roundup). The case being heard in federal court in San Francisco now moves to the damages phase. Last August in San Francisco Superior Court, a California groundskeeper was awarded $39 million in compensatory damages, and $250 million in punitive damages in a case that linked his NHL to Monsanto’s glyphosate/Roundup. In October, the judge in the case upheld the verdict, but reduced the award to $78 million. According to the Associated Press, the trial judge, U.S. Judge Vince Chhabira “is overseeing hundreds of Roundup lawsuits and has deemed [this case] and two others ‘bellwether trials.“ The case was brought by Edwin Hardeman of Santa Rosa, CA. He said he had been using Roundup since the 1980’s. During the trial, according to The Guardian, Judge Chhabria, “approved Monsanto’s request to prohibit Hardeman’s attorneys from raising allegations about the corporation’s conduct, saying issues about its influence on science and government were a ‘significant … distraction.’” This set up a limitation that required the plaintiff’s attorneys to focus solely on studies linking the chemical to cancer […]

(Beyond Pesticides, March 5, 2019) Wild, edible plants subject to drift from the herbicide glyphosate during forestry operations can be contaminated with the chemical an entire year after an initial application, according to a new study published in the Canadian Journal of Forest Research. Glyphosate is often used in forestry to knock down unwanted trees, shrubs, and other plants after clear-cutting to provide room for the regrowth of trees deemed valuable. However, this new research shows that “non-target” species, such as raspberries and blueberries, eaten by wildlife and sometimes wild foraged by humans can retain significant levels of glyphosate contamination due to drift and overspray. Forester Lisa Wood, PhD, from the University of Northern British Columbia began this research based on input and requests from Canadian indigenous First Nations communities. Back in 2013, shrubs foraged by traditional berry-pickers in northeastern British Columbia were sampled and found to contain glyphosate residues, leading to the need for a broader investigation. Dr. Wood sampled the roots and shoots of 10 plant species from an area that had been aerially sprayed with glyphosate a year prior as part of forestry operations to clear aspen and make room for coniferous re-plantings. The 10 plants, which […]

(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, November 7, 2018) Brazil’s rapid industrialization of its agricultural sector may be coming at the cost of resident health, according to a new study published in Chemosphere by an international team of scientists. The researchers link the rise in the country’s pesticide use since the turn of the century to significant increases in colon cancer, particularly in the country’s most intensive agricultural southern regions. With the recent election of far right president Jair Bolsonaro, who has supported policies that would loosen Brazil’s pesticide regulations, advocates are concerned the county’s farming industry is moving in an unsustainable direction. Researchers note that as Brazil’s agriculture industry has grown over the last two decades, it has become the world’s leading consumer of pesticides. In the year 2000, roughly 160 million tons of pesticides were used in the country. By 2012, that number reached nearly 500 million tons. Scientists compared pesticides sold to standard mortality rates (SMR) in each Brazilian state. SMR measures mortality by comparing observed mortality to expected mortality when adjusting for age and gender. A rate above one indicates that there is excessive mortality. Despite improvements in detection and treatment, colon cancer deaths recorded in the country increased from […]

(Beyond Pesticides, October 31, 2018) Residents in the town of Great Barrington, MA are concerned about the health effects that could result from creosote-coated railroad ties stored in their neighborhood. According to a report in the Berkshire Eagle, soon after the Massachusetts Department of Transportation (MDOT) parked a load of railroad ties along tracks that cut through a neighborhood, community members began to complain about the smell. Creosote is a mixture of thousands of different chemical compounds. Derived mainly from coal tar and regulated as a pesticide by the U.S. Environment Protection Agency (EPA), the material represents a significant hazard that puts people and the environment in danger, and can be readily replaced by safer, alternative materials. “I would want to roll up my windows immediately,” Beth Rose told the Berkshire Eagle. Another Great Barrington resident, Jeanne Bachetti, told the paper, “I started to smell them right after they moved [them] in there. Sometimes we get a propane smell from [nearby] AmeriGas, so I couldn’t tell. Then it dawned on me — that’s not gas.” MDOT is currently in the process of a project to upgrade roughly 40 miles of freight line, and is using 60,000 railroad ties as part […]

(Beyond Pesticides, August 16, 2018) The jury verdict last week awarding groundskeeper Dewayne “Lee” Johnson $289 million in compensatory and punitive damages because of the carcinogenic effect caused by the herbicide glyphosate/Roundup, which he used, brought to the forefront a long standing concern about inadequate regulation of hazardous pesticides and chemical industry corruption. In the case, the jury heard from numerous scientists and medical experts, including Christopher Portier, Ph.D., who has researched the toxicity and carcinogenicity of glyphosate. One of the challenges in the court case was overcoming the lack of regulatory action on glyphosate, despite the overwhelming science indicating its adverse effects, including its connection to non-Hodgkin lymphoma. Globally, food safety agencies have spent the past few years insisting that glyphosate is not carcinogenic. Health and environment advocates point to the 2015 International Agency for Research on Cancer (IARC) designation of glyphosate as a “probable carcinogen” as the knell to which regulators, pesticide users, and the public should pay attention. The jury listened and considered the scientific facts. Glyphosate has perhaps been the subject of more controversy than any other pesticide in recent memory. Advocates in the scientific and environmental realms note the multiple risks its use represents, while […]

(Beyond Pesticides, February 9, 2018) Attorneys General in eleven states join Monsanto and the National Wheat Growers Association last month in challenging California’s listing of glyphosate as a carcinogen under the state’s Proposition 65 law. California added glyphosate to the list of cancer-causing chemicals in July 2017, but has since been attacked by Monsanto and its allies for carrying out state law that requires carcinogens to be labeled and monitored. The plaintiffs, led by the National Association of Wheat Growers, argue that listing glyphosate as a carcinogen under Prop 65 will irreparably harm the agriculture industry, adversely affecting farmers and consumers throughout the U.S. The case, seeking a stay of the listing, was filed in the in Federal Court in the Eastern District of California in November, 2017. Earlier last year, Monsanto lost its case before a state Superior Court in which it sought to stay the Prop 65 listing. Idaho, Indiana, Iowa, Kansas, Louisiana, Michigan, Missouri, North Dakota, Oklahoma, South Dakota and Wisconsin have filed an amicus brief in support of the preliminary injunction sought by agriculture groups against California’s Prop 65 regulation. The U.S. Chamber of Commerce and the California Chamber of Commerce filed their own amicus brief in support of […]

(Beyond Pesticides, December 21, 2017) On December 18, the U.S. Environmental Protection Agency (EPA) declared that glyphosate is likely not carcinogenic. Relatedly, after weeks of stalemate on a decision by European countries, the European Union (EU) voted, in late November, to extend the license for the herbicide for another five years, despite massive opposition in member countries. In the U.S., the Center for Biological Diversity charged that the EPA assessment relied heavily on industry studies to arrive it its conclusion, and ignored its own guidelines for assessing cancer risks. Senior scientist at the Center for Biological Diversity Nathan Donley said, “The only way the EPA could conclude that glyphosate poses no significant risks to human health was to analyze industry studies and ignore its own guidelines when estimating cancer risk. . . . The EPA’s biased assessment falls short of the most basic standards of independent research and fails to give Americans an accurate picture of the risks posed by glyphosate use.” Glyphosate is due for its EPA registration review in 2019, and opponents are concerned that the December 18 announcement portends likely re-registration — which advocates say is bad news for human health and the environment. As the chief […]

(Beyond Pesticides, July 10, 2017) The state of California has listed glyphosate, the active ingredient in the popular Roundup, as a known carcinogen under its Proposition 65 law. This listing went into effect July 7, 2017. Now, state officials have to develop guidelines for product labels and determine what level of exposure to the pesticide will put people at risk for developing cancer. Some have argued that the state’s proposed levels are not protective enough. Meanwhile, the state continues to face pressure from Monsanto, maker of glyphosate, which continues to challenge the decision to list the chemical as a known cancer-causing agent. California’s decision to list glyphosate as a carcinogen was prompted by the International Agency for Research on Cancer’s (IARC) finding in 2015 that it is a “probable” human carcinogen. This classification was based on sufficient evidence of carcinogenicity in experimental animals. Later that year, California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) announced that it intended to list glyphosate as a cancer-causing chemical under California’s Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65).  Under California law, Proposition 65 requires that certain substances identified by IARC be listed as known cancer-causing chemicals. Glyphosate’s listing became effective […]
