(CBS News) -- Consumers are being urged not to buy pig-ear dog treats nor feed them to their pets during an outbreak of salmonella that has expanded to 33 states and sickened 127 people, including 26 hospitalizations.
The warning issued Wednesday by the U.S. Food and Drug Administration and the U.S. Centers for Disease Control and Prevention comes amid an investigation that has prompted two separate recalls in recent days and weeks. The agencies also advised retailers to stop selling all pig-ear treats for now.
Lennox Group, one of two companies that have recalled the product, on Tuesday expanded its previous action, saying it knew of multiple cases of people getting ill from salmonella, with several people identifying Lennox pig ear treats as the brand they had purchased. In its initial recall notice, Lennox said it was aware of two cases in which its pig ears caused dog Illnesses.
Some of the pig ear pet treats originated from Argentina and Brazil, the FDA and CDC said.
The warning extends to pig-ear dog treats already in homes: "handling these treats could make people sick; eating the treats could make dogs sick," the CDC said in its own post. Tests have identified "many different strains in salmonella in pig ears from various brands and suppliers," according to the agency. It added that data on where ill people bought pig ears has not identified a single supplier, distributor or common brand of pig ear treats.
