People may absorb toxic industrial chemicals from some brands of dental floss, a new study says. It’s the latest evidence that Americans are routinely exposed to this vast class of chemicals, known as PFAS, some of which have been linked to heart disease and cancer.
Although scientists have known that PFAS are used in Glide, “this finding suggests that it may be more important than expected,” said Courtney Carignan, an associate professor of food science and toxicology at Michigan State University who was not part of the study.
“I’m not trying to tell people, ‘don’t floss,’” Katie Boronow, a staff scientist at the Silent Spring Institute in Newton, Massachusetts, who was part of the study, told BuzzFeed News. “It’s about choosing safer products.”
A spokesperson for CVS Pharmacy said by email that the company is “committed to assuring that the products we offer are safe, work as intended, comply with regulations and satisfy customers. We will be reviewing the study and will also contact the supplier of this product.”
Colgate-Palmolive and Safeway did not respond to requests for comment from BuzzFeed News.
