The U.S. Food and Drug Administration(FDA) has recently issued a warning informing consumers not to eat the frozen shrimp being sold at Walmart. The FDA Recalls Walmart Shrimp on August 19, 2025, mentioning that the shrimp at Walmart might be contaminated with Cesium-137 (Cs-137).

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

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, as it could have been exposed to a dangerous isotope in shipping containers.
