The risky chemicals that keep cooking grease from leaking out of fast-food containers are widespread, according to a peer-reviewed study released Wednesday.

Researchers said they detected fluorine in nearly half the 400 container samples from 27 fast-food chains, including the four largest in the U.S., McDonald’s Corp., Starbucks Corp., Chipotle Mexican Grill Inc. and Yum! Brands Inc. That’s an indication that potentially dangerous chemicals, called PFAS, were present in wrappers for popular items like burgers, burritos and pastries, the authors said.
