Walmart pulled certain shrimp from its shelves in 13 states after the FDA raised concerns about potential radioactive contamination.

"If you were eating shrimp all the time, like on a daily basis, then there might be more concern," Kowalcyk told the NYT.

The Food and Drug Administration has warned the public not to consume a brand of frozen shrimp sold at Walmart stores in 13 states because it may have been exposed to radioactive material.
