FDA Warning Issued
The U.S. Food and Drug Administration has sounded an unusual alarm in the frozen-food aisle. According to an agency alert, select packages of Great Value frozen shrimp—carried nationwide by Walmart—may be contaminated with the radioactive isotope Cesium-137.

What We Know So Far
Product: Great Value frozen shrimp
Retailer: Walmart
Potential Hazard: Cesium-137 contamination
Source of Alert: U.S. Food and Drug Administration
Date of Advisory: August 19, 2025

Why Cesium-137 Matters
Cesium-137, a by-product of nuclear fission, is known for its radioactive properties and potential health impacts if ingested. While the FDA has not detailed concentration levels in this initial notice, the mere presence of the isotope in food prompts immediate regulatory attention.

Consumer Guidance
In its statement, the FDA emphasized that the warning applies only to “some packages” of the product. The agency advised shoppers who have purchased Great Value frozen shrimp from Walmart to monitor the FDA’s website and any store-posted notices for next steps, which may include disposal instructions or possible recall information.

Next Steps
Regulators are continuing to evaluate the situation. For now, consumers are urged to remain vigilant and await further details from the FDA regarding the scope of the contamination and any required corrective actions.

“Food safety is our first priority,” the agency said in its notice, adding that updates will be provided “as soon as they become available.”
