PFAS chemicals are made up of a chain of linked carbon and fluorine atoms, which do not degrade in the environment.<br />A 2015 CDC report found endocrine-disrupting PFAS have been detected in the blood of 97% of Americans.<br />According to CNN, they're used in all sorts of consumer products, including fast food packaging.<br />Foods that contain a lot of grease -- such as burgers, fries, and cookies -- are prime candidates for wrappers made with PFAS.<br />While earlier forms of PFAS have already been banned, experts say newer forms appear to have many of the dangerous health effects as the older versions.<br />What's more, they appear to migrate even faster from the paper to the fast food it wraps.<br />They've been found in the packaging for Burger King's 'Whopper,' chicken nuggets and cookies, and in McDonald's wrappers for the 'Big Mac,' fries, and cookies.
