The San Diego-based chain today became the first national pet specialty retailer to ban Chinese-made treats from its shelves. The action came days after the U.S. Food and Drug Administration reported that more than 5,600 dogs and 24 cats had became ill over the past seven years after eating jerky treats. More than 1,000 dogs died.

No proof has been found to conclusively link jerky to the pet illnesses. Most of the jerky was produced in China.

Chinese-made dog and cat treats will disappear from Petco’s 1,300 stores, its website and Unleashed by Petco locations over the coming months.

“We know some pet parents are wary of dog and cat treats made in China, especially chicken jerky products, and we’ve heard their concerns,” says Petco CEO Jim Myers.

“Very simply, we feel this decision is in the best interest of the pets we all love and, ultimately, for our business,” he adds.

The FDA investigation and the agency’s latest update spurred Petco to act.

“We’ve been following the FDA warnings and related customer concerns closely, and we’ve been actively reducing our China-made assortment and expanding our American-made offerings for several years now,” Myers says. “We know the FDA hasn’t yet identified a direct cause for the reported illnesses, but we decided the uncertainty of the situation outweighs the lack of actual proof.

“It has taken some time and careful thought to get to this point, but we’re proud to make the change and we believe our customers will be pleased with it as well.”

Among the brands Petco is touting as alternatives to Chinese-made treats are selections from U.S. companies such as American Jerky, Blue Buffalo, Canidae, Dogswell, Merrick, Nature’s Variety and Zuke’s as well as treats and chews from New Zealand, Australia and South America.
