Excerpt: The next time you get a muffin with your coffee or pick up a hamburger at a drive-thru, you could also be getting a side of chemicals that have a poor safety and environmental record, a new study shows.
Researchers tested more than 400 samples of bags, wrappers, boxes, and cups from 27 fast-food and fast-casual restaurant chains in the U.S. in 2014 and 2015.
Many of these kinds of paper packaging and paperboard containers are laced with per- and polyfluoroalkyl substances, or PFASs, they found.
PFASs, also called fluorinated chemicals, are a big class of more than 3,000 widely used chemicals that make things grease- and stain-resistant. The problem is, the substances don’t break down over time. That means they build up in the environment and in our bodies.
