A dog in Missouri became sick after chewing on pet treats made from pig ears, which prompted the recall of a product that may be contaminated with Salmonella.

Keys Manufacturing Company of Paris, IL said its recalled Pig Ears for Pet Treats were distributed in Pennsylvania, Virginia, Missouri, Iowa, Ohio, Illinois, Florida, Kentucky, Michigan, Arkansas, Indiana, Louisiana, Texas and Minnesota.

The product was distributed in 100-count cases packed in cardboard boxes shipped between Sept. 27-Oct. 6, 2010; Nov. 1-Nov. 29, 2010; and Jan. 3-Jan. 25, 2011.

The company said it has been working with the FDA to identify any products that might contain the bacteria and to determine what caused the problem.

Consumers who purchased Pig Ears for Pet Treats can return them to the place of purchase for a full refund. Consumers with questions may contact the company at 1-217-465-4001.

Salmonella not only can can affect animals, but there is risk of infection to humans who handle contaminated pet products. Wash your hands after contact with the pet chews or any surfaces exposed to these products.

Pets with Salmonella infections may be lethargic and have diarrhea or bloody diarrhea, fever, and vomiting. Some pets will have only decreased appetite, fever and abdominal pain. Infected but otherwise healthy pets can be carriers and infect other animals or humans. If your pet has consumed the recalled product and has these symptoms, contact a veterinarian.
