For so many parents, frozen shrimp is a weeknight lifesaver—quick to cook, affordable, and something kids will actually eat without a fight. But this week, Walmart pulled certain shrimp from its shelves in 13 states after the FDA raised concerns about potential radioactive contamination.

Walmart has recalled frozen, raw shrimp sold in 13 states because federal health officials say it could have potential radioactive contamination.

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