Federal testing confirmed trace amounts of radioactive cesium in frozen shrimp tied to Walmart’s Great Value brand, and the FDA on Aug. 19 urged consumers not to eat, sell, or serve specific lot codes while investigators trace the contamination. The agency says radiation monitors at U.S. ports flagged several containers from Indonesia and an FDA lab confirmed Cs‑137 in one sample.
What regulators found and what they’re telling consumers
FDA testing measured the confirmed sample at roughly 68.48 becquerels per kilogram (±8.25), well below the agency’s Derived Intervention Level of 1,200 Bq/kg, but still enough for officials to recommend that the implicated lots be pulled from commerce. The agency identified three lot codes of 2‑pound Great Value Frozen Raw Vannamei shrimp (Best‑By March 15, 2027) and has advised consumers who purchased those bags to dispose of them or return them to Walmart for a refund.
Per the FDA advisory, Customs and Border Protection radiation alarms first drew attention to the shipments, and FDA added the Indonesian processor, PT. Bahari Makmur Sejati (BMS Foods), to an import alert that allows detention of future shipments without physical exam while the agency investigates. Retailers receiving the implicated lots have been instructed to remove them from sale and distributors have been told to prevent further distribution.
Major cities most likely affected
FDA’s advisory lists affected shipments that were distributed to stores in 13 states. Based on those states and the largest metropolitan areas within them, the biggest population centers most likely to have received impacted product include Dallas–Fort Worth and Houston in Texas, and Atlanta in Georgia. These cities are called out because they are the largest metros in the states the FDA named — they are not the only places affected, and product was distributed across smaller markets as well.
If you live in any of the affected states — Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Missouri, Mississippi, Ohio, Oklahoma, Pennsylvania, Texas, or West Virginia — check freezer bags for lot codes 8005540‑1, 8005538‑1, or 8005539‑1 and the March 15, 2027 Best‑By date. Do not eat or serve matching product.
What Cs‑137 is and public‑health context
Cesium‑137 is a man‑made radioactive isotope produced by nuclear fission and monitored by public‑health agencies because ingestion can contribute to long‑term cancer risk. Federal pages on isotopes explain that while a single low‑level detection is unlikely to produce immediate symptoms, regulators treat any unexpected presence of Cs‑137 in food seriously and use port radiation screening combined with lab confirmation to keep contaminated shipments out of commerce.
Legal and regulatory fallout
FDA’s finding that product “appears to have been prepared, packed, or held under insanitary conditions” can be cited under the Federal Food, Drug, and Cosmetic Act and underpins the import alert and recall recommendation. The import alert prevents the processor from sending product into U.S. supply chains until it provides acceptable corrective actions and documentation to regulators.
What to do if you bought the shrimp
Check any Great Value frozen raw shrimp in your freezer for the lot codes and dispose of or return matching bags to Walmart for a refund. If you’re concerned about exposure or have health questions, contact your healthcare provider; federal public‑health resources on Cs‑137 and radiation exposure offer additional information.
