The current tsunami of lawsuits against Monsanto over glyphosate’s deadly attributes are serving to refocus scrutiny on Monsanto’s past interaction with the EPA. Jim
“It’s been 34 years since Monsanto Co. presented U.S. regulators with a seemingly routine study analyzing the effects the company’s best-selling herbicide might have on rodents. Now, that study is once again under the microscope, emerging as a potentially pivotal piece of evidence in litigation brought by hundreds of people who claim Monsanto’s weed killer gave them cancer.
“This week tissue slides from long-dead mice in that long-ago research study are being scrutinized by fresh eyes as an expert pathologist employed by lawyers for cancer victims looks for evidence the lawyers hope will help prove a cover-up of the dangers of the weed killer called glyphosate.
“Glyphosate, which is the active ingredient in Monsanto’s branded Roundup products, is the most widely used herbicide in the world, and is applied broadly in the production of more than 100 food crops, including wheat, corn and soy, as well as on residential lawns, golf courses and school yards.
“Residues have been detected in food and human urine, and many scientists around the world have warned that exposure through diet as well as through application can potentially lead to health problems. The World Health Organization’s International Agency for Research on Cancer (IARC) declared glyphosate a probable human carcinogen in 2015 based on a review of scientific literature, triggering the wave of lawsuits against Monsanto, and pushing California regulators to announce they would add glyphosate to a list of known carcinogens…
“A February 1984 memo from Environmental Protection Agency toxicologist William Dykstra stated the findings definitively: ‘Review of the mouse oncogenicity study indicates that glyphosate is oncogenic, producing renal tubule adenomas, a rare tumor, in a dose-related manner.’ Researchers found these increased incidences of the kidney tumors in mice exposed to glyphosate worrisome because while adenomas are generally benign, they have the potential to become malignant, and even in noncancerous stages they have the potential to be harmful to other organs. Monsanto discounted the findings, arguing that the tumors were ‘unrelated to treatment’ and showing false positives, and the company provided additional data to try to convince the EPA to discount the tumors…
“Monsanto fought the plaintiffs’ request to view the mouse tissue slides, calling it a ‘fishing expedition,’ but was overruled by U.S. District Judge Vince Chhabria who is overseeing the roughly 60 combined lawsuits under his purvey. Monsanto has confirmed that roughly 900 additional plaintiffs have cases pending in other jurisdictions. All make similar claims – that Monsanto manipulated the science, regulators and the public in ways that hid or minimized the danger posed by its herbicide.”
