Glyphosate—the active ingredient in Monsanto‘s Roundup weedkiller that some studies have linked to cancer—is also a secret ingredient in nearly 20 popular beers and wines.

That’s the finding of a new study from the education group U.S. PIRG, which found glyphosate in 19 of 20 wine and beer brands tested, including organic labels and brews.
