“The levels in nearly half of the meat and fish tested were double or more the only currently existing federal advisory level for any kind of the widely used manmade compounds, which are called per- and polyfluoroalkyl substances, or PFAS.”  

"PFOS, an older form of PFAS no longer made in the U.S., turned up at levels ranging from 134 parts per trillion to 865 parts per trillion in tilapia, chicken, turkey, beef, cod, salmon, shrimp, lamb, catfish and hot dogs. Prepared chocolate cake tested at 17,640 parts per trillion of a kind of PFAS called PFPeA."
