EPA Using Industry-Funded Research to Determine if Glyphosate Causes Cancer

The U.S. Environmental Protection Agency (EPA) used industry-funded research to conclude that the herbicide chemical glyphosate is not likely to cause cancer in humans—contradicting findings by the World Health Organization (WHO)—according to an analysis the EPA posted to, then swiftly removed from, its website on Friday.

“EPA’s determination that glyphosate is non-carcinogenic is disappointing, but not terribly surprising—industry has been manipulating this process for years,” said Nathan Donley, a scientist with the Center for Biological Diversity (CBD). “The analysis done by the World Health Organization is more open and transparent and remains the gold standard.”

The agency’s since-deleted analysis (pdf), which includes an October 2015 memorandum from its Cancer Assessment Review Committee (CARC), states:

Groups cited in the analysis include private biochemical firms like Inveresk Research International, Nufarm, and Arysta Life Sciences.

WHO reported the exact opposite in a groundbreaking March 2015 study, which prompted a wave of measures against the use of the chemical. California placed it on the state’s public ‘cancer list’ in September, while workers around the country lined up to sue Monsanto for conducting what they called a “prolonged campaign of misinformation” to convince farmers, consumers, and the government that its Roundup line of products was safe to use.

As CBD points out, because the studies cited in the EPA’s analysis are unpublished, they have not been subject to public scrutiny. In addition, they focus on testing glyphosate as a singular ingredient, rather than looking at the effects of herbicides available in stores.
