evidence: Last year, two rounds of tests commissioned by EWG found glyphosate – the active ingredient in Roundup and the most widely used herbicide in the world – in more than 95 percent of popular oat-based food samples. Today we are releasing the results of tests of 12 wheat-based products, including five samples of dried pasta and seven samples of cereal. [...] Most glyphosate is sprayed on "Roundup ready" corn and soybeans genetically engineered to withstand the herbicide. Increasingly, glyphosate is also sprayed just before harvest on wheat, barley, oats and beans that are not genetically engineered. Glyphosate kills the crop, drying it out so it can be harvested sooner than if the plant were allowed to die naturally. [...] Earlier this month, Friends of the Earth tested 30 samples of oat products and 27 samples of dry pinto beans, and found glyphosate in every sample tested. And on Monday, U.S. PIRG released results of tests on 15 beers and five wines. In all but one of the samples, glyphosate was found at levels five to 100 times lower than what is found in oats.
