Some packages of Great Value frozen shrimp sold at Walmart are at risk for potential for Cesium-137 contamination, the FDA says.

Great Value brand frozen shrimp sold at Walmart stores in Ohio could be contaminated with Cesium-137, warns the FDA.

Certain raw frozen shrimp products sold in Walmart under the Great Value brand have been recalled after Cesium-137, or Cs-137, was detected in shipping containers at four U.S. ports, according to the Food and Drug Administration.
