Some pet parents know about the risks raw meat diets pose to pets. Bacterial contamination can still make pets sick, but there are other dangers, too.

A recent study showed that although various commercial dog foods carried some undesirable bacteria, raw meat diets were more likely to contain bacteria resistant to multiple antibiotics. These bacteria are especially dangerous when transmitted to immunosuppressed people or pets. In addition, there are risks posed to the public by the dissemination of multidrug-resistant bacteria.

Some still tout the benefits of raw food diets, but most such claims haven’t been proven. However, evidence of the potentially dangerous effects is building — especially as they impact immunocompromised, very young or elderly dogs. Now it looks like the same may hold true for their humans.
