evidence: While the U.S. Environmental Protection Agency (EPA) does not currently allow chlormequat use on any food crops, in 2018 the Trump administration approved its use on imported oats and, two years later, increased the allowable level on food from 10 parts per million (ppm) to 30 ppm. [...] Previous research from EWG found the pesticide in 92% of oat-based foods , including in Quaker Oats and Cheerios. In April last year, Taminco, which manufactures chlormequat, asked the EPA to allow the chemical on U.S.-grown barley, oats and wheat. The EPA proposed allowing the change , but the proposed rule isn’t finalized.
