Walmart has recalled some of its shrimp products in the US after radioactive material was detected in a shipment of seafood. The US Food and Drug Administration (FDA) warned the public not to eat frozen shrimp sold under Walmart's Great Value label, as it could have been exposed to a dangerous isotope in shipping containers.

“To date, FDA has learned that Walmart has received implicated raw frozen shrimp, imported after the date of first detection of Cs-137 by CBP [Customs & Border Patrol], but from shipments that did not alert for Cs-137,” the statement noted.
