Radioactive shrimp Walmart warning is making headlines after the U.S. Food and Drug Administration (FDA) issued an urgent health alert. Consumers are being told not to eat certain frozen shrimp sold at Walmart due to possible contamination with a radioactive substance called Cesium‑137. Here’s what’s happening, what it means for your health, and how to stay safe.
What Triggered the Radioactive Shrimp Walmart Warning?
During routine inspections at ports in Los Angeles, Houston, Savannah, and Miami, U.S. Customs and Border Protection detected Cesium‑137, a radioactive isotope, in shrimp shipments from PT Bahari Makmur Sejati, also known as BMS Foods, based in Indonesia.
The FDA later confirmed that at least one sample of breaded shrimp tested positive for Cesium‑137. As a result, the agency placed an import ban on all BMS Foods shrimp and issued a public safety warning. While only one sample tested positive, the FDA is urging Walmart to recall all potentially affected lots as a precautionary measure.
Which Products Are Affected?
Consumers should check their freezers for the following product:
- Brand: Great Value (Walmart store brand)
- Product: Frozen Raw EZ Peel Tail-On Farm-Raised White Vannamei Shrimp
- Weight: 2-lb bag
- Lot Codes: 8005540‑1, 8005538‑1, 8005539‑1
- Best-by Date: March 15, 2027
These shrimp products were distributed in at least 13 U.S. states, including Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Missouri, Mississippi, Ohio, Oklahoma, Pennsylvania, Texas, and West Virginia.

What Is Cesium‑137 and Why Is It Dangerous?
Cesium‑137 is a radioactive element produced during nuclear reactions. While very small amounts are naturally present in the environment due to past nuclear testing, elevated levels in food products can be harmful when consumed over time.
Health risks associated with Cesium‑137 exposure include:
- Increased risk of certain cancers from DNA damage
- Long-term internal radiation exposure from ingestion
- Cellular damage from low-dose but persistent exposure
The FDA stated that the shrimp sample contained approximately 68 becquerels per kilogram (Bq/kg) of Cesium‑137. While this is below the FDA’s legal limit of 1,200 Bq/kg, the agency considered the detection significant enough to warrant a product warning due to the cumulative nature of radiation exposure.
What the FDA Is Doing About It
The FDA has taken the following steps:
- Issued an Import Alert to block further shrimp shipments from BMS Foods.
- Requested Walmart to recall the affected shrimp, even if only one sample was confirmed contaminated.
- Published a consumer alert advising the public not to eat the specific Great Value shrimp packages.
- Initiated a traceability review to ensure no additional contaminated products are in the supply chain.
The FDA has made it clear that while the detected levels of radioactivity are not immediately harmful, caution is necessary when radioactive elements are found in food products.
What Is Walmart Doing?
Walmart has pulled the affected shrimp products from its shelves and distribution centers. Consumers who purchased the shrimp are being offered full refunds upon return of the product packaging or receipt.
Walmart is working with the FDA and the supplier to gather additional information and ensure that no other products in its seafood line are affected. The company has not reported any illnesses related to this incident.
What Should You Do If You Bought This Shrimp?
Here’s what to do if you believe you have purchased the potentially contaminated shrimp:
- Do not eat the product. Even if you already consumed some, stop using it immediately.
- Check the packaging for the lot numbers and best-by date mentioned above.
- Return it to Walmart for a full refund or properly discard the shrimp.
- Contact your healthcare provider if you have health concerns or experience unusual symptoms.
At this time, no illnesses have been reported, and the FDA has stated that short-term exposure is unlikely to cause immediate health effects. However, it’s better to avoid any potential risk.
How Did Radioactive Shrimp End Up in Stores?
The shrimp came from a supplier in Indonesia, a country known for exporting large quantities of farmed seafood. It’s still unclear how Cesium‑137 entered the supply chain. Possible sources include:
- Contaminated water used in shrimp farming
- Improper handling near industrial waste sites
- Exposure during transportation or packaging
The FDA is currently working with international food safety partners to investigate the cause and prevent similar incidents in the future.
Why This Warning Is a Big Deal
The radioactive shrimp Walmart warning shines a light on key food safety concerns in today’s globalized economy:
- Global Supply Chain Risks: U.S. consumers often depend on imported food. This increases the risk of contamination from sources with different safety standards.
- Regulatory Vigilance: The FDA and U.S. Customs play a critical role in detecting threats before they reach our plates.
- Consumer Awareness: Understanding how to identify recalled products can help keep families safe.
While Cesium‑137 contamination in food is rare, it’s not unheard of. In previous years, trace levels have been found in imported mushrooms and seafood. However, those cases often did not trigger consumer alerts like this one.
Could There Be More Contaminated Shrimp?
At this point, the FDA has not announced additional positive tests beyond the single sample. However, the agency has emphasized that their investigation is ongoing. More recalls or updates could be issued if new evidence surfaces.
Consumers are urged to stay informed by checking the FDA website or subscribing to food recall alerts.

Conclusion: Safety Comes First
The radioactive shrimp Walmart warning is a reminder that even familiar grocery brands can face unexpected risks. Thanks to the FDA’s early detection and Walmart’s prompt cooperation, the situation is being managed swiftly.
While there is no cause for panic, consumers should take the warning seriously. If you have any of the shrimp in question, dispose of it immediately and stay informed about any further updates.
