Jerky treat mystery: Nearly 600 pets dead; still no source, FDA says
by JoNel Aleccia

Nearly 600 pets have died and more than 3,600 have been sickened in an ongoing, mysterious outbreak of illnesses tied to jerky treats made in China, federal animal health officials said Tuesday.

Most of the cases have been in dogs of all breeds, ages and sizes, although 10 cats have been sickened, too. The pace of the reported illnesses appears to have slowed, but federal Food and Drug Administration officials are now seeking extra help from veterinarians and pet owners in solving the ongoing puzzle.

“To date, testing for contaminants in jerky treats has not revealed a cause for the illnesses,” Martine Hartogensis, a deputy director for the FDA’s Center for Veterinary Medicine, said in the new report. “Despite these warnings, we have continued to receive reports of illnesses in both cats and dogs.”

The new numbers are up from some 500 deaths and 3,200 illnesses tallied in January, but the rate of reports has fallen sharply since then, mostly because two of the largest sellers of pet chicken jerky treats announced recalls tied to the presence of unapproved antibiotic residue detected in the products.

FDA officials don’t think that antibiotic residue is the big problem that has stumped the agency since 2007, when pet owners started reporting their animals were suffering gastrointestinal and kidney problems after eating the popular jerky treats.

Instead, it’s likely that the recall of Nestle Purina PetCare Co.’s Waggin Train and Canyon Creek Ranch treats, plus Del Monte Corp.’s Milo’s Kitchen Chicken Jerky and Chicken Grillers home-style dog treats simply resulted in fewer treats being available. Two other smaller producers also recalled the treats because of the problem.

In fact, FDA officials remain as uncertain as ever about the source of the problem that has led to reports of illnesses and warnings about the possibility of Fanconi syndrome and other kidney problems in animals that ate jerky treats.
