Many people are understandably suspicious of ground beef. It’s a common vector of E. coli, salmonella and saturated fat. But one batch of ground beef, distributed in Virginia and the Carolinas over the past few weeks, has been found to harbor a more unusual contaminant: blue plastic chips. Food Safety News reports that the chips have not been associated with any health concerns. This has led the FDA to issue a class III recall on the affected 1642 pounds of beef; class III recalls are reserved for those products that do not present any serious risks to human health.
