FDA notices Cs-137 risk in Walmart shrimp
A batch of Great Value frozen raw shrimp imported from Indonesia may contain Cesium-137. The FDA recommends disposing of the affected lots and Walmart is urged to recall the product.

The FDA warns that some Great Value frozen shrimp from Walmart may carry Cesium-137, prompting a recall advisory and consumer guidance.
FDA flags Cs-137 risk in Walmart Great Value shrimp
U.S. regulators say a batch of Great Value brand frozen raw shrimp imported from Indonesia could be contaminated with Cesium-137. The FDA says the product was sold at Walmart and has recommended a recall. The lots listed are 8005540-1 with best by 3/15/2027, 8005538-1 with best by 3/15/2027, and 8005539-1 with best by 3/15/2027. The agency notes the affected shipment did not enter U.S. commerce and Walmart has not yet commented. The Cesium-137 detected in the shipment was about 68 Bq/kg, below the FDA's 1200 Bq/kg threshold; however, repeated low-dose exposure could carry cancer risk over time.
Distributors and retailers should dispose of the product and not sell or serve it, per the FDA warning. Cesium-137 is a radioactive isotope produced by nuclear fission and is a byproduct of nuclear reactors and weapons testing. The FDA emphasizes that while the level found poses no acute hazard, the warning aims to reduce long-term exposure and protect consumers who may encounter repeated exposure over time.
Key Takeaways
"Distributors and retailers should dispose of this product and should not sell or serve this product."
FDA warning directive
"At this level, the product would not pose an acute hazard to consumers."
FDA risk assessment
"Avoiding products like the shipment FDA tested with similar levels of Cs-137 is a measure intended to reduce exposure to low-level radiation that could have health impacts with continued exposure over a long period of time."
FDA warning rationale
"This recall tests whether brands can balance price with safety in a global supply chain."
editorial takeaway
This incident tests how fast safety warnings move through a global supply chain. A single detected shipment can trigger a wider recall and ripple across Walmart shelves and consumer trust. It also highlights the challenge of screening imported seafood for rare contaminants and the need for clear, timely communication from regulators and retailers. As supply chains grow longer, stronger vetting of suppliers and more transparent risk information become essential for public confidence.
Highlights
- Safety should be the default, not a response after the fact.
- A recall is a test of trust for big retailers.
- One shipment is a signal, not a verdict.
- Public health must lead this kind of risk, not profits.
Radiation risk in imported seafood prompts recall and consumer caution
The FDA warning raises concerns about import vetting, supplier transparency, and the speed at which recalls are issued for potentially radioactive contamination. While the detected cesium level is below the agency’s acute-hazard threshold, the potential for long-term exposure prompts precautionary actions and could affect consumer confidence in store brands and imported foods.
Regulators and retailers will need to translate this warning into safer choices for shoppers.
