Packaged in Pollution: Are food chains using PFAS in packaging?
New testing indicates major fast-food chains are still serving up PFAS (per- and polyfluoroalkyl substances) with some of their most popular takeout foods, despite increasing consumer demand and legislative action to phase out the use of toxic PFAS chemicals. Nearly half of all food packaging samples tested positive for fluorine above the screening level, including for fast-food favorites such as McDonald’s Big Mac, Burger King’s Whopper, and Sweetgreen’s salads and warm bowls.
