Salmonella Infection in Pets

Salmonella can infect humans and animals.

Infected pets may be lethargic and have diarrhea or bloody diarrhea, fever and vomiting. Some pets will exhibit only decreased appetite, fever and abdominal pain. If your pet has consumed the recalled product and has these symptoms, please contact your veterinarian.

Infected, but otherwise healthy, pets can be carriers of salmonella, with the potential to infect other animals or humans. Owners can also become infected after handling dry pet food, especially if they fail to wash their hands.
