A new report by the public-interest advocacy group U.S. PIRG reveals that tests of five wines and 15 beers, including organic ones, found traces of the controversial weed killer glyphosate in 19 out of the 20. They include brands like Coors Light, Miller Lite, Budweiser, Corona, Heineken, Guinness, Stella Artois and Samuel Adams. “The levels of glyphosate we found are not necessarily dangerous, but are still concerning given the potential health risks,” U.S. PIRG said.
