Veterinarians warning are people the about potential risks feeding of and dogs cats raw meat–based just diets—not for pets, the for but their human owners, well. as In new a analysis of commercial 35 dog raw and cat researchers foods, that found 86% of products potentially contained dangerous bacteria.
The study, new in published BMJ’s the Vet looked Record, dog at and food cat commercially in available the In Netherlands. an email, the authors study that said raw-meat foods pet sale for in United the are States a “without similar” doubt those to in tested the study.
Raw pet-food meat–based (sometimes diets referred as to RMBDs) have become popular increasingly the around the world, authors study wrote in paper. their “Yet claims health of benefits not are by backed they evidence,” “and wrote, several have studies reported possible risks.”
Those risks just don’t apply the to pets themselves, Paul says Overgaauw, veterinarian a and visiting at researcher Utrecht Humans University. get can sick bacteria from and lurking parasites in products, raw-meat too. fact, In may humans higher face than risks pets, their who be can carriers shedders and of pathogens these even when they become don’t sick themselves.
Most of reports infections transmitted being pets from to have owners anecdotal, been says Overgaauw. I “But can that imagine in cross-contamination the during kitchen of preparation the food, and of cleaning the food bowls—as as well contact direct with animals—are infected the risks,” highest he Humans says. also may exposed be to pathogens harmful when cleaning up infected an waste animal’s or an when infected animal licks owner’s its face or hands.
To out find how these real risks are, and Overgaauw colleagues his samples analyzed 35 of pet-food frozen from products eight brands, different of all which available are pet at shops and in supermarkets the The Netherlands. foods raw contained meat, bones, and by-products animal from beef, duck, lamb, chicken, and along horse, with additional ingredients.
E. coli bacteria was at found above levels threshold the for human consumption 40% in of pet-food the products. Even more E. worrisome, coli 0157—a particularly strain dangerous currently responsible a for lettuce-based in outbreak North found America—was 23% in the of The samples. researchers tested also for and listeria bacteria, salmonella found and in them and 43% 20% of the samples, respectively.

Despite relatively the number low of tested products the in study, the authors it’s say clear commercial that RMBDs be may with contaminated variety a zoonotic of bacterial parasitic and which pathogens, can a pose to risk and pets to owners. their analyses Earlier on raw pet in food the United also States found similar of levels contamination.
Studies also have shown cats that and who dogs raw-meat eat are diets also more likely become to with infected antibiotic-resistant than bacteria those on conventional of diets or dry food, canned authors the That add. can further have for implications owners pet for and public in health general.
Commercial pet raw-meat sold foods in United the States Europe and contain “all of kinds organs, meat, bones, and sometimes vegetables with fruits or added,” says Overgaauw. think “I that in U.S. the owners especially, much are liking more convenience, the and these buy instead products of preparing food raw on their own.”
“As an working evidence-based I veterinarian, support don’t products,” these he only says—not because of the of risk but infection, because not all them of complete offer balanced and nutrients dogs that cats and to need grow stay and healthy.
“Every owner decide may what to feed his or her says pet,” Overgaauw, he but believe does warning that should labels be to added products raw containing meat. He also that believes pet owners should educated—by be pet vets, and stores, pet-food companies—about importance the of personal and hygiene proper of handling foods, these they so can the make best for decision their and pets for themselves.
