The FDA is warning the public about eating certain Great Value raw frozen shrimp sold at some Walmart stores around the country.
The agency issued the warning after a Customs and Border Protection alerted the agency about possible Cesium-137 contamination, a radioactive isotope, from shipping containers.
Frozen shrimp from the distributor has tested positive, but the FDA says no shrimp that has tested positive has entered the U.S. food supply. The product is sold at Walmart stores in more than a dozen states.
