Commercial beef often undergoes an acid wash for sterilization before sale, and subsequent plastic wrapping can lead to plastic breakdown and contamination of the beef with plastics and plasticizers.

“In a lot of commercial beef, they have to spray it with an acid wash to sterilize it before it goes to like Whole Foods. And then Whole Foods wraps it in plastic. And that combination of the acidic wash plus the plastic breaks down some of the plastic and it goes into the beef.”
