That’s because, according to new research, such wrappers commonly contain the toxins perfluorinated chemicals (PFCs) or polyfluoroalkyl and perfluoroalkyl substances (PFASs). None of the paper cups analyzed came back with detectable levels of fluorine. Additionally, 20 percent of the subsection had detectable levels of PFOA, a synthetic and potentially carcinogenic PFC previously used to make Teflon. The study did not test for these chemicals in the food itself, but previous research has shown that the chemicals in food wrapping can migrate from the wrapper to the food. The study noted that hotter, greasier foods ― like many of the items sold at fast food restaurants ― are the most likely sources of chemical-leaching.
