NEW YORK – Nestle Purina PetCare is taking Waggin' Train and Canyon Creek Ranch brand dog treats off the market because the products may contain trace amounts of a poultry antibiotic that isn't approved in the U.S.

The chicken jerky products, which are made in China, may contain minute amounts of antibiotic residue, Purina said Wednesday. The antibiotic has been approved by Chinese and European Union regulators, but not in the U.S.

The treats are safe to feed to pets, Purina said. Still, they are being taken off the market in the U.S. until further notice.
