Salmonella can affect animals and there is risk to humans from handling contaminated pet products. People handling dry pet food and-or treats can become infected with Salmonella, especially if they have not thoroughly washed their hands after having contact with the 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. If your pet consumed the recalled product and has these symptoms, please contact your veterinarian.
