The US Food and Drug Administration (FDA) has posted a consumer advisory for certain frozen shrimp products marketed under Walmart’s Great Value since tests revealed possible cesium-137 contamination, a radioactive isotope. The involved product was processed by PT Bahari Makmur Sejati (BMS Foods), an Indonesian seafood company, the agency stated in its latest press release.
Products Affected
The FDA notice includes particular lots of Great Value Frozen Raw White Vannamei Shrimp (2 lb packs) that have been distributed at Walmart stores in various states, such as Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Missouri, Mississippi, Ohio, Oklahoma, Pennsylvania, Texas, and West Virginia.
Everyone…heads up!

Discovery of Cesium-137
The problem was brought to light after U.S. Customs & Border Protection (CBP) detained shipping containers at four of the largest ports – Los Angeles, Houston, Savannah, and Miami – as a possible cesium-137 contamination. The FDA later on tested and confirmed to have detectable traces of the isotope in a sample of breaded shrimp from PT Bahari Makmur Sejati.
The positive sample equaled 68 Bq/kg, well short of the FDA’s Derived Intervention Level of 1,200 Bq/kg. Although the agency emphasized that this value is not an immediate concern for health, chronic exposure over time may be a matter of safety concern.
Avoid the Great Value shrimp from Walmart… Because of the shelf half-life?! 😬 #RadioactiveShrimp ☢️🍤

The FDA explained, “avoiding products like the shipment FDA tested with similar levels of Cs-137 is a measure intended to reduce exposure to low-level radiation that could have health impacts with continued exposure over time.”
Health Risks of Cesium Exposure
Cesium-137 is a byproduct of nuclear reactions and can contaminate food via environmental exposure. The isotope emits radiation capable of damaging DNA, and repeated long-term exposure may increase cancer risk.

The FDA mentioned that trace levels of naturally occurring cesium are present in soil, air, and water across the globe. Nevertheless, unanticipated discoveries in imported foods must be carefully examined.
