Plain-English summary
A group of 28 research dogs was tested to see if they would shed Salmonella bacteria after eating raw food diets contaminated with Salmonella. Out of the 16 dogs that ate the contaminated food, 7 started shedding the bacteria within a week, while none of the dogs that ate safe food showed any signs of illness. Interestingly, some of the bacteria found in the dogs matched the types found in the contaminated food. This study highlights that dogs eating contaminated raw diets can spread Salmonella, which could pose health risks to both pets and people.

Abstract
Twenty-eight research dogs were enrolled to determine the prevalence of salmonellae shedding after consumption of 1 Salmonella-contaminated commercial raw food diet meal. Sixteen dogs were exposed to Salmonella-contaminated commercial raw food diets and 12 to Salmonella-free commercial raw food diets. Seven of the exposed dogs shed salmonellae 1-7 days after consumption of Salmonella-contaminated raw food diets. None of the dogs fed Salmonella-free diets shed salmonellae. No clinical signs were observed in either group. Five of the 7 dogs shed the same serotypes as those recovered from food samples used for feeding. Results showed the same serotypes and antimicrobial resistance pattern in 2 of the 7 shedders. Dogs fed Salmonella-contaminated raw food diets can shed salmonellae and may, therefore, be a source of environmental contamination potentially leading to human or animal illness.
