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

The FDA is currently investigating reports of Cesium-137 radioactive contamination in shipping containers and frozen shrimp products.

Walmart has recalled some of its shrimp products in the US after radioactive material was detected in a shipment of seafood. The US Food and Drug Administration (FDA) warned the public not to eat frozen shrimp sold under Walmart's Great Value label could have been exposed to a dangerous isotope in shipping containers.
