Monsanto weed-killer found in Cheerios and Quaker Oats after lawsuit

The nonprofit Environmental Working Group found traces of weed-killer in breakfast foods like Cheerios and Quaker Oats products.The chemical in question, known as glyphosate, has been tentatively linked to cancer, though many scientists argue that the evidence isn't conclusive.A California couple was recently awarded $2 billion in a lawsuit concerning the same chemical, which they said caused their non-Hodgkin's lymphoma.As the scientific community awaits further research, consumers are left to decide whether glyphosate poses a risk.The Environmental Working Group has conducted multiple tests to determine the presence of weed-killer in certain breakfast foods.In August 2018, the group published a report that found traces of glyphosate, the most widely used agricultural pesticide in the world, in dozens of Quaker, Kellogg's, and General Mills products, including cereals like Cheerios and Lucky Charms.The report tested levels of glyphosate in 45 samples of conventionally grown oats and determined that 31 fell below its safety criteria. Ten weeks later, the EWG tested another 28 samples, focusing exclusively on Cheerios and Quaker Oats products, and found that all but two showed harmful levels of glyphosate, according to its measures.We don't yet know whether glyphosate is actually linked to cancer. As it stands, most published research has found that glyphosate isn't a health threat at the low levels to which consumers are exposed.Does glyphosate cause cancer？Certain scientific groups have insisted there is a link between glyphosate and cancer, but others aren't convinced.Organizations such as the Environmental Protection Agency, the European Commission, Canada's Pest Management Regulatory Agency, and the World Health Organization's International Program on Chemical Safety have determined that glyphosate does not present a public health concern.Much of the argument surrounding glyphosate boils down to a report published by the WHO's International Agency for Research on Cancer that said the herbicide was “probably carcinogenic in humans.” But an extensive review of the material by Reuters found that the IARC had edited parts of the document that didn't align with its conclusion.While some scientists have backed away from the IARC's findings, others are doubling down.Alex Lu, an associate professor of environmental exposure biology at Harvard, described the IARC as a “world-renowned and reputable” institution whose findings have benefited global cancer researchers. Having conducted his own research of pesticides in children's diets, Lu said he believed the EWG's safety measures were relatively conservative and that its threshold “is too high.”“This is especially true for parents buying breakfast cereals for their infants and children,” said Lu, who is not affiliated with the EWG, though it has covered his findings in the past.The EWG considers any cereal with a glyphosate level of more than 160 parts per billion to be unsafe. The legal limit for oats — as outlined by the Environmental Protection Agency — is 30 parts per million, or 30,000 parts per billion, for adults, making the EWG's threshold nearly 188 times as stringent as the EPA's regulations (though it's common to enforce stricter limits for children).“Since children have an increased susceptibility to cancer-causing substances, it's standard scientific practice to include a tenfold margin of safety,” said Tasha Stoiber, a senior scientist at the EWG.A string of lawsuits has occurred over the possible link between glyphosate and cancerAround the same time that EWG released its August report, a judge ordered Monsanto to pay $78.6 million in damages to a groundskeeper who attributed his cancer to Roundup, the company's popular herbicide, which uses glyphosate as the active ingredient. The judge ruled that Monsanto had intentionally withheld information about Roundup's potential harm, but did not make any claims about whether it contributed to the plaintiff's cancer.On March 19, however, a federal jury ruled that Roundup was a “substantial” contributor to another man's cancer diagnosis in 2015. After using the weed-killer to tend his property for more than two decades, 70-year-old Edwin Hardeman said Roundup caused his non-Hodgkin's lymphoma. The jury has since ordered Monsanto to pay Hardeman $81 million for failing to warn about the risks of Roundup. Hardeman is one of tens of thousands of plaintiffs who have filed similar claims against Monsanto, which was recently acquired by Bayer. On May 13, a California jury ordered Monsanto to pay $2 billion in damages to a husband and wife, Alva and Alberta Pilliod, who each developed non-Hodgkin lymphoma after using Roundup for 35 years. In a statement, Bayer said it would appeal the verdict.“We have great sympathy for Mr. and Mrs. Pilliod, but the evidence in this case was clear that both have long histories of illnesses known to be substantial risk factors for non-Hodgkin's lymphoma,” the company said in a statement.But the Pilliod case focused on the consequences of spraying Roundup — not ingesting traces of it. Are Cheerios safe to eat？In the wake of the EWG's findings, both General Mills and Quaker have insisted their products are safe to eat. The companies released statements to Fast Company citing their compliance with EPA standards.“Our products are safe and without question they meet regulatory safety levels,” General Mills said.“Once the oats are transported to us, we put them through our rigorous process that thoroughly cleanses them,” Quaker said in a statement, adding, “Any levels of glyphosate that may remain are significantly below any regulatory limits.”But it still warrants the question: Are the EPA's standards up to par？A 2017 study published in the Journal of Epidemiology and Public Health argued that it could be time to reassess our criteria. It found enough evidence to suggest that the existing EPA safety standards for glyphosate is “outdated and may fail to protect public health or the environment.”In 2017, court documents revealed conversations between Monsanto and federal regulators, which suggested that a senior EPA official tried to suppress a federal study of glyphosate.The EWG has also claimed that the EPA's standards for pesticides and other chemicals are “heavily influenced by lobbying from industry.” Despite these claims, there's still not enough data to conclusively determine a risk. For this reason, Lu said, people might want to limit their exposure to glyphosate as a precautionary measure.Those worried about the safety of their breakfast foods should consider what the EWG has to say about individual foods.Of the 28 new samples, the group found that Quaker Oatmeal Squares cereal showed the highest levels of glyphosate, nearly 18 times as high as its safety threshold.Other foods that stood out as particularly hazardous by the report's standards included Quaker Overnight Oats and Cheerios' Oat Crunch Cinnamon flavor. But even these foods wouldn't be considered unsafe by the EPA.As with any scientific study, it's possible that new research could shed light on the EWG's warnings. Even studies that once seemed definitive have been called into question. The US Department of Health and Human Services recently determined that, after decades of being labeled a carcinogen, a zero-calorie sweetener called saccharin is not thought to cause cancer.It's also possible that scientists could uncover new safety concerns for crops like wheat, barley, beans, and chickpeas, which are exposed to glyphosate before harvest.
