And while no one wants to bite down on stainless steel in peanut butter or bone fragments in smoked sausage, this type of contamination is one of the top reasons for food recalls in the U.S. Food safety experts and federal agencies use the terms 'extraneous' or 'foreign' materials to describe things like metal fragments, rubber gaskets and bits of bugs that somehow make it into packaged goods.
