No, the chances of your pet contracting salmonella poisoning are very low. Cats and dogs regularly become carriers of Salmonella, and may shed Salmonella and other bacteria in their stools without displaying any symptoms of Salmonella infection.
Your pet, however, may be susceptible to Salmonella and other bacteria if your pet has a suppressed or compromised immune system. A balanced raw diet helps to build a strong immune system and maintain healthy gut flora, keeping your pets safe from disease-causing pathogens, including Salmonella.
The bigger concern is to keep humans safe from Salmonella when feeding raw. As the usual route of Salmonella infection is faecal-oral, exercise basic hygiene and practise some common sense: do not eat your cat or dog’s poop, wash your hands and keep surfaces clean.
