If you have a dog or cat that became ill after eating jerky pet treats, the Food and Drug Administration (FDA) would like to hear from you or your veterinarian.

The agency has repeatedly issued alerts to consumers about reports it has received concerning jerky pet treat-related illnesses involving 3,600 dogs and 10 cats in the U.S. since 2007. Approximately 580 of those pets have died.

To date, FDA’s Center for Veterinary Medicine (CVM) has conducted more than 1,200 tests, visited jerky pet treat manufacturers in China and collaborated with colleagues in academia, industry, state labs and foreign governments. Yet the exact cause of the illnesses remains elusive.

To gather even more information, FDA is reaching out to licensed veterinarians and pet owners across the country. “This is one of the most elusive and mysterious outbreaks we’ve encountered,” says CVM Director Bernadette Dunham, DVM, Ph.D. “Our beloved four-legged companions deserve our best effort, and we are giving it.”

In a letter addressing U.S. licensed veterinarians, FDA lists what information is needed for labs testing treats and investigating illness and death associated with the treats. In some cases, veterinarians will be asked to provide blood, urine and tissue samples from their patients for further analysis. FDA will request written permission from pet owners and will cover the costs, including shipping, of any tests it requests.

Meanwhile, a consumer fact sheet will accompany the letter to veterinarians so they can alert consumers to the problem and remind them that treats are not essential to a balanced diet. The fact sheet also explains to consumers how they can help FDA’s investigation by reporting potential jerky pet treat-related illnesses online or by calling the FDA Consumer Complaint Coordinator for their state.

Severe cases have involved kidney failure, gastrointestinal bleeding, and a rare kidney disorder. About 60 percent of cases involved gastrointestinal illness, and about 30 percent involved kidney and urinary systems.

The remaining cases reported various symptoms, such a
