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

The Food and Drug Administration has recalled three more lots of frozen shrimp over concerns the products may be contaminated with a radionuclide (Cesium-137). The recall applies to a limited quantity of Great Value frozen raw shrimp EZ-peel & deveined tail-on 21-25 per pound packages.

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.
