Walmart has initiated a recall of specific shrimp products after concerns were raised about potential radioactive contamination. The US Food and Drug Administration (FDA) has warned that frozen shrimp sold under the Great Value brand might have been exposed to Caesium-137, a radioactive isotope discovered in a sample from a shipment. Although the affected sample did not reach the market, consumers in 13 states are advised to dispose of recently purchased shrimp from three implicated batches.

"We take the health and safety of our customers seriously," a spokesperson for Walmart stated. They further affirmed that the company has acted swiftly by placing sales restrictions and removing the affected products from store shelves. Customers who possess the recalled shrimp are encouraged to return the items to any Walmart location for a full refund.

The shrimp in question was sourced from an Indonesian supplier, which has had various shipping containers barred from entering the US due to contamination concerns. The FDA has confirmed that while the tested amount of Caesium-137 was not sufficient to cause immediate health risks, prolonged exposure could potentially increase the risk of cancer by inflicting damage on cellular structures. This radioactive element, primarily a result of nuclear reactions, can also be found in minute quantities in the environment.

As of now, the FDA has not detected Caesium-137 in other tested shrimp products but has cautioned that this does not entirely eliminate the possibility of contamination in the food supply. The agency continues to monitor the situation closely to safeguard public health.
