A Facebook group called Animal Parents Against Pet Treats and Food Made in China is warning pet owners about jerky treats from China that are under investigation by the US Food and Drug Administration.

The group is attaching warnings to packages of these treats in stores that read: "Beware! FDA investigates pet treats from CHINA. Thousands of complaints filed. Hundreds of deaths reported."

Since 2007, more than 3,600 dogs and 10 cats have reportedly become ill and 580 of these died from eating jerky treats, most of which came from China, said Linda Tollefson, associate commissioner for FDA's Office of Foods and Veterinary Medicine. However, FDA has been unable to isolate a contaminant so a recall for the treats has not been issued.
