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.

More packages of frozen shrimp potentially affected by radioactive contamination have been recalled, federal officials said Thursday.

FDA expands frozen shrimp recall to nine states, including California; consumers urged to check bags and not eat listed products.
