Weedkiller found in granola and crackers, internal FDA emails show
The Food and Drug Administration (FDA) has been testing food samples for residues of glyphosate, the active ingredient in hundreds of widely used herbicide products, for two years, but has not yet released any official results.
But the internal documents obtained by the Guardian show the FDA has had trouble finding any food that does not carry traces of the pesticide.
“I have brought wheat crackers, granola cereal, and cornmeal from home and there’s a fair amount in all of them,” FDA chemist Richard Thompson wrote to colleagues in an email last year regarding glyphosate. Thompson, who is based in an FDA regional laboratory in Arkansas, wrote that broccoli was the only food he had “on hand” that he found to be glyphosate-free.
That internal FDA email, dated January 2017, is part of a string of FDA communications that detail agency efforts to ascertain how much of the popular weedkiller is showing up in American food. The tests mark the agency’s first-ever such examination.
“People care about what contaminants are in their food. If there is scientific information about these residues in the food, the FDA should release it,” said Tracey Woodruff, a professor in the University of California San Francisco School of Medicine. “It helps people make informed decisions. Taxpayers paid for the government to do this work, they should get to see the information.”
The FDA is charged with annually testing food samples for pesticide residues to monitor for illegally high residue levels. The fact that the agency only recently started testing for glyphosate, a chemical that has been used for over 40 years in food production, has led to criticism from consumer groups and the Government Accountability Office (GAO). Calls for testing grew after the International Agency for Research on Cancer (IARC) classified glyphosate as a probable human carcinogen in 2015.
