August 22, 2025 — The U.S. Food and Drug Administration has announced a voluntary recall of frozen shrimp products due to possible contamination with Cesium-137 (Cs-137), a man-made radioisotope that can elevate cancer risks through longer term, repeated low dose exposure.
The announcement comes shortly after U.S. Customs and Border Control (CBP) detected Cs-137 in shipping containers at the Ports of Los Angeles, Houston, Savannah, and Miami, with agents finding evidence of the radioisotope in a single shipment of frozen bread shrimp. The discovery led the FDA to issue an alert for frozen shrimp supplied by Indonesia-based PT. Bahari Makmur Sejati to Walmart and sold under the “Great Value” brand name.
