Walmart is recalling certain frozen shrimp products sold under its Great Value brand after the U.S. Food and Drug Administration (FDA) warned that the seafood may be at risk for radioactive contamination. The frozen shrimp were imported from Indonesian company PT. Bahari Makmur Sejati and sold in 13 states, the FDA said.

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

The US Food and Drug Administration on Tuesday urged the public not to eat certain bags of frozen raw shrimp sold at Walmart, citing concerns about unsanitary conditions and radioactive contamination found in shipments from the same supplier.
