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

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