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

Days after the FDA issued a do-not-eat warning about imported shrimp sold at Walmart, a Florida company actually issued a recall of that shrimp and a California company recalled shrimp sold under five other brands.

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.
