Study Finds 80 Percent Americans Exposed to Fertility-Lowering Chemicals in Cheerios, Quaker Oats

According to a recent study, four in five Americans tested positive for an agricultural chemical found in several wheat and oat products, including brands like Cheerios and Quaker Oats. The peer-reviewed study, published in the JESEE journal on Feb. 15, looked at urine samples from American citizens to determine their exposure to chlormequat chloride—a plant growth chemical. Exposure to the chemical can result in lower fertility and harm developing fetuses even at doses below acceptable levels set by regulators. Researchers detected chlormequat in 80 percent of urine samples collected between 2017 and 2023, with “a significant increase in concentrations for samples from 2023.” The chemical was detected in “92 percent of oat-based foods purchased in May 2023, including Quaker Oats and Cheerios,” said the Environmental Working Group (EWG), which conducted the study....
