US retail giant Walmart has recalled some shrimp products in 13 states after a shipment of the product tested positive for radioactive contamination.

The US Food and Drug Administration said varieties of the seafood sold under the retailer’s Great Value label could have been exposed to the hazardous material while being shipped in containers.

One sample of breaded shrimp tested positive but “did not enter US commerce”, the FDA said in a statement.

It has advised customers to throw away any shrimp recently bought at Walmart that matches this description and not to eat or serve it.

“The health and safety of our customers is always a top priority,” a Walmart spokesperson told the BBC. “We have issued a sales restriction and removed this product from our impacted stores. We are working with the supplier to investigate.”

The spokesperson added that any customers who had bought the recalled products could visit their local Walmart for a full refund.

The US states where the recalled shrimp were sold are Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Missouri, Mississippi, Ohio, Oklahoma, Pennsylvania, Texas and West Virginia.

The shrimp came from an Indonesian supplier, a shipment of which tested positive for Cesium-137, which is the radioactive form of the chemical element Cesium.
