Healthy cats and dogs have natural defenses to certain bacteria. We have all seen what they will put in their mouths or lick down at the park!
The salivary glands in cats and dogs contain the enzymes lysozyme and peroxidase, lactoferrin, defensins, cystian and an antibody, lgA, which are all antibacterial. In the stomach the pH balance drops to 1 and 2. That’s equal to the pH balance of Hydrochloric acid. The strong stomach acid is not only there to digest raw meat and bone, it helps kill off unwanted bad bacteria. This is only part of the body’s defenses.
This is not to say that dog and cats can not get sick from bacteria like salmonella – they are just better at defending the body from them.
Nutriment food products are tested for salmonella and other bacteria to the full extent required by law and we only ever use fresh meat and other ingredients fit for human consumption.
