Why Did FDA Issues Warning on Walmart Shrimp Recall Over Possible Radioactive Contamination

The U.S. Food and Drug Administration (FDA) has issued a serious warning to consumers about frozen shrimp sold at Walmart under its Great Value brand, after testing revealed potential exposure to radioactive material. The agency confirmed that certain lots of imported shrimp may contain Cesium-137, a radioactive isotope that poses health risks with prolonged exposure.

What Happened?

According to the FDA, shipping containers from an Indonesian supplier tested positive for traces of Cesium-137 during routine screening. While some containers were denied entry into the U.S., the FDA believes a limited amount of product already reached Walmart’s shelves before detection.

The affected shrimp includes the following:

• Great Value Frozen Raw Shrimp (16 oz)
• Lot codes: 8005540-1, 8005538-1, 8005539-1
• Best-by date: March 15, 2027

If you have shrimp in your freezer that matches these details, the FDA urges you to stop consuming it immediately and discard it.

Why Is Cesium-137 Dangerous?

Cesium-137 is a byproduct of nuclear reactions and has been linked to increased cancer risks if consumed regularly over time. While the levels detected were below the threshold for immediate harm, long-term exposure—even in small amounts—can be dangerous.

The FDA stressed that this recall is a precautionary measure to protect public health.

What Should Shoppers Do?

• Check your freezer for Great Value frozen raw shrimp with the listed lot numbers.
• Do not eat it—even if it looks and smells fine.
• You may return the product to Walmart for a refund or safely dispose of it.

Consumers with health concerns are advised to contact their healthcare provider.

Walmart’s Response

Walmart has already started pulling the affected shrimp from store shelves and online listings. The company said in a statement that it is “working closely with the FDA to ensure the safety of our customers and to prevent further distribution of the product.”

Why This Matters for Shoppers

Food safety recalls are not uncommon, but radioactive contamination is extremely rare in the seafood industry. With shrimp being one of the most consumed types of seafood in the U.S., this case highlights the importance of strict screening of imported products.

For now, Walmart shoppers are encouraged to stay alert, double-check their freezers, and rely on FDA updates.
