[Contamination of dog feed with salmonella (author's transl)].

In a comparative investigation of dog feed the percentage of contamination with Salmonellae was determined. 5.7% out of 229 uncooked animal organs, which belonged to 6 different feed-kitchens, were S.-positive. None of the 40 dried feed samples and of the 30 tinned rations examined were positive. The most frequent serotype was S. derby (var. 0-5 neg). The results confirmed our former conclusions (3), that the dog is to be considered an accidental host of enteric salmonella ingested with the feed. Dried or tinned feed is considered as an improvement which minimises the risk of distribution of salmonella, especially high in imported feed.
