January 25, 2013 — The Hartz Mountain Corporation of Secaucus, New Jersey, has announced it is voluntarily withdrawing its Hartz Chicken Chews and Hartz Oinkies Pig Skin Twists wrapped with Chicken for dogs in the United States because they contain trace amounts of antibiotic residue.
Hartz is taking this action after recent testing found trace amounts of illegal antibiotic residue in samples of the affected dog treats.
These antibiotics are approved for use in poultry in China and other countries but are not in the U.S.
