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.

Some packages of Great Value frozen shrimp sold at Walmart are at risk for potential for Cesium-137 contamination, the FDA says.

More bagged, frozen shrimp are part of another recall issued by the U.S. Food and Drug Administration (FDA) on Aug. 21. This recall affects 13 products that may have also been contaminated with radioactive isotope Cesium-137 across nine states.
