Toxic Chemical Linked to Infertility Discovered in Popular Oat-Based Foods

A study by the Environmental Working Group found that the pesticide chlormequat, linked to infertility in animals, was detected in the majority of oat-based foods sold in the U.S., including popular brands like Quaker Oats and Cheerios. The chemical was found in 77 of 96 urine samples taken from 2017 to 2023, with levels increasing in recent years. While the EPA allows chlormequat to be used on ornamental plants only, its use has been permitted on imported oats and other foods sold in the U.S. since 2018. The EWG opposes the EPA's proposal to allow chlormequat use on certain crops grown in the U.S. Organic oat products are recommended to reduce exposure to chlormequat, as they are grown without synthetic pesticides.
