Radioactive shrimp. That’s not a typo. That’s not clickbait. That’s what’s going down at Walmart right now. The retail giant has issued a multi-state recall for several lots of its Great Value frozen shrimp after the FDA flagged potential contamination with Cesium-137 — a radioactive byproduct most commonly associated with nuclear reactors and atomic bombs.

A widening seafood safety scare has prompted federal officials to expand a nationwide shrimp recall for the second time in a week. Walmart’s popular Great Value brand to the growing list of products pulled from store shelves over concerns about possible radioactive contamination.

The Food and Drug Administration issues a second recall on frozen shrimp after potential exposure to radioactive material.
