Animal-source proteins of concern include beef, pork, poultry, fish, and other meat from domesticated or wild animals as well as milk* and eggs. Several studies1–6 reported in peer-reviewed scientific journals have demonstrated that raw or undercooked animal-source protein may be contaminated with a variety of pathogenic organisms, including Salmonella spp, Campylobacter spp, Clostridium spp, Escherichia coli, Listeria monocytogenes, and enterotoxigenic Staphylococcus aureus. Cats and dogs may develop foodborne illness after being fed animal-source protein contaminated with these organisms if adequate steps are not taken to eliminate pathogens; secondary transmission of these pathogens to humans (eg, pet owners) has also been reported.1,4 Cats and dogs can develop subclinical infections with these organisms but still pose a risk to livestock, other nonhuman animals, and humans, especially children, older persons, and immunocompromised individuals.
To mitigate public health risks associated with feeding inadequately treated animal- source protein to cats and dogs, the AVMA recommends the following:
* The recommendation not to feed unpasteurized milk to animals does not preclude the feeding of unpasteurized same-species milk to unweaned juvenile animals.
