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.
Out of 25 conventional oat products tested, 23 had “detectable levels” of chlormequat. One in eight organic oat products had the chemical, while two in nine wheat products had low concentrations of chlormequat.
Researchers collected 96 urine samples, out of which 77 showed the presence of chlormequat. The numbers suggest that the subjects likely underwent “continuous exposure” to the chemical since chlormequat leaves the body about 24 hours after ingestion.
