The FDA has expanded its recall of frozen shrimp over potential radioactive contamination, now affecting more U.S. states.

FDA advises public not to eat, sell, or serve certain imported frozen shrimp from an Indonesian firm - This recall is due to possible contamination with Cesium-137. The products were sold at Walmart stores in Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Missouri, Mississippi, Ohio, Oklahoma, Pennsylvania, Texas and West Virginia.

So, if you have shrimp in your freezer or thawing in your refrigerator, check to make sure it’s not from Sand Bar, Arctic Shores, Best Yet, First Street, Great American Seafood Imports or Walmart’s Great Value brand.
