FDA is investigating reports of Cesium-137 (Cs-137) contamination in shipping containers and frozen shrimp products processed by PT. Bahari Makmur Sejati (doing business as BMS Foods) of Indonesia. The U.S. Customs & Border Protection (CBP) alerted FDA to the detection of Cs-137 in shipping containers at four U.S. ports (Los Angeles, Houston, Savannah, and Miami). FDA collected multiple samples for radionuclide analysis, with results confirming the presence of Cs-137 in one sample of breaded shrimp. Although testing to date has not confirmed the presence of contamination in any product in commerce, the product appears to have been prepared, packed, or held under insanitary conditions whereby it may have become contaminated with Cs-137 and may pose a safety concern. To date, FDA has learned that Walmart has received implicated raw frozen shrimp, imported after the date of first detection of Cs-137 by CBP, but from shipments that did not alert for Cs-137. FDA has recommended Walmart recall this product. Consumers should not eat or serve certain lots of Great Value raw frozen shrimp sold at Walmart stores in AL, AR, FL, GA, KY, LA, MO, MS, OH, OK, PA, TX, and WV. The FDA has concluded that the level detected in the breaded shrimp sample could represent a potential health concern. @ https://www.fda.gov/food/alerts-advisories-safety-information/fda-advises-public-not-eat-sell-or-serve-certain-imported-frozen-shrimp-indonesian-firm
