FDA warns against eating certain shrimp sold at Walmart amid investigation into radioactive contamination

(CNN) — The US Food and Drug Administration on Tuesday urged the public not to eat certain bags of frozen raw shrimp sold at Walmart, citing concerns about unsanitary conditions and radioactive contamination found in shipments from the same supplier.

The FDA said that a radioactive isotope, cesium-137, was detected in a sample of breaded shrimp detained at US ports – in Los Angeles, Houston, Savannah, and Miami – from an Indonesian supplier named BMS Foods.

Those contaminated shipments never reached the US market. However, because Walmart’s raw frozen shrimp came from the same supplier – and the agency said it “appears to have been prepared, packed, or held under insanitary conditions whereby it may have become contaminated with Cs-137” – officials advised consumers to avoid eating them.
