Walmart has recalled some shrimp products in 13 US states after one shipment of seafood tested positive for radioactive contamination. The US Food and Drug Administration said varieties of frozen shrimp sold under Walmart's Great Value label could have been exposed to a dangerous isotope in shipping containers.

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

The shrimp possibly affected is sold at Walmarts in thirteen states, including in Florida, Texas and Pennsylvania
