FDA warns Walmart shrimp may be contaminated
The FDA warns consumers to discard certain Walmart frozen shrimp due to possible Cs-137 contamination and advises medical advice if exposure is suspected.

FDA warns certain Walmart frozen shrimp may be contaminated with Cs-137 and urges disposal.
Walmart shrimp contamination prompts FDA safety warning
The FDA said on Tuesday that some frozen raw shrimp sold at Walmart may be contaminated with the radioactive substance Cesium-137. The agency ties the issue to shipping containers and products processed by the Indonesian company PT Bahari Makmur Sejati, known as BMS Food, with the affected items arriving in 13 states under Walmart's Great Value frozen shrimp line. U.S. customs officials reported Cs-137 positive containers were blocked from entry in Los Angeles, Houston, Miami and Savannah, and all positive shipments were denied admission.
The agency noted that tested samples did not exceed the current intervention level of 1200 Bq/kg, but it warned that the level detected in a breaded shrimp sample could represent a potential health concern if combined with radiation exposure from other sources. The FDA advised consumers who purchased raw frozen shrimp matching the described description to discard the product and to consult a healthcare provider if exposure is suspected. Walmart and the Indonesian supplier did not immediately respond to requests for comment.
Key Takeaways
"If you have recently purchased raw frozen shrimp from Walmart that matches this description, throw it away."
FDA advisory to consumers
"Cs-137 is the radioactive form of Cesium, a soft, flexible, silvery-white metal that becomes liquid near room temperature."
Scientific background on contaminant
"The level detected in the breaded shrimp sample could represent a potential health concern."
Health officials on risk potential
The episode highlights how quickly a food safety scare can move through a modern supply chain. Screening at ports and the rapid public health advisory show a functioning system, but the incident also tests public trust in familiar brands and imported goods. Even when measurements stay below official thresholds, uncertainty remains about the cumulative risk to consumers who eat multiple foods or rely on higher-risk diets. The episode may press regulators to tighten traceability and require clearer labeling for imported seafood.
Highlights
- Safety must outrun the shipping clock
- Trust in groceries is earned not assumed
- A warning on a bag should never be routine
- Public health safety depends on fast clear guidance
Public health risk from contaminated seafood triggers alert
Cs-137 contamination in seafood products can pose health risks, especially with cumulative exposure. The alert covers numerous shipments and a major retailer, raising questions about traceability, supplier oversight, and consumer trust.
Public health safety depends on speed, transparency, and clear guidance for shoppers.
