Purina says the chicken jerky products may contain minute amounts of antibiotic residue. The treats are made in China, and the antibiotic has been approved by regulators in that country as well as European Union nations. But it isn't approved in the U.S.
The company, a U.S. division of Switzerland's Nestle, says the treats are safe to feed to pets. Still, they are being taken off the market in the U.S. until further notice.
The recall doesn't apply to Canyon Creek Ranch dog and cat foods.
