FDA warns public not to eat possibly radioactive shrimp sold at Walmart

The Food and Drug Administration is warning the public not to eat, sell or serve certain Great Value raw frozen shrimp sold at Walmart due to possible contamination with Cesium-137, a radioactive isotope.

U.S. Customs and Border Protection alerted the FDA about possible Cesium-137, or Cs-137, detected in shipping containers at four U.S. ports, the FDA said Tuesday in a press release. Testing on frozen shrimp from the distributor, Indonesia's BMS Foods, also tested positive, the FDA said.

However, no shrimp that has tested positive for Cesium-137 has entered the U.S. food supply, according to the FDA.
