Twenty-one people in New Hampshire became ill after becoming infected with salmonella from pet treats, Joey's Jerky. 

According to The Concord Monitor, the minor outbreak has prompted a recall of the Joey's Jerky brand chicken jerky, a dog treat, made by Kritter's Kitchen Kreations. There is no listing on the Food and Drug Administration website. 

"While uncommon, pet food and treats can sometimes be contaminated with salmonella, which is why it is so important for pet owners to wash their hands after handling pet food and treats," Dr. José Montero, public health director of the New Hampshire Department of Health and Human Services, said in a statement.

The illness was reported in Merrimack and Hillsborough counties. 

According to the Monitor, state officials are waiting for test results to determine whether the treats are positive for the same strain of salmonella that sickened the 21 people. The Huffington Post reported the dog treats are suspected to be involved in the salmonella outbreak were sold at six stores in New Hampshire: America's Pet in Hudson, Blue Seal in Bow, K9 Kaos in Dover, Osborne's Agway in Concord, Sandy's Pet Food Center in Concord, and The Yellow Dogs Barn in Barrington.

New Hampshire health authorities advised people to dump the jerky in the trash.
