An extensive international survey conducted at the University of Helsinki indicates that pet owners do not consider raw food to considerably increase infection risk in their household. In the survey, targeted at pet owners, raw food was reliably determined to be a contaminant only in three households.
The safety of feeding raw food to pets has become a topic of debate on a range of forums, but so far, no outbreaks of contamination among humans caused by raw pet food have been reported. Raw food denotes any meat, internal organs, bones and cartilage fed to pets uncooked.
Now, a survey conducted at the Faculty of Veterinary Medicine investigated perceptions on food-transmitted pathogens among pet owners who feed their pets raw food.
A total of 16,475 households from 81 countries responded to the survey. Out of these, only 39 households (0.24%) reported having been contaminated by pet food, and were also able to name the pathogen. The most common pathogens reported were Campylobacteria followed by Salmonella, in addition to which there were occurrences of Escherichia coli, Clostridium, Toxoplasma and a single Yersinia infection.
