Salmonella are important pathogenic bacteria as cause of disease both for human and animal. If dogs fed Salmonella-contaminated food, dogs can shed Salmonella with feces. In US, surveillance of Salmonella-contaminated wet dog foods were carried out. However there are little reports on surveillance of Salmonella-contaminated wet dog foods in Japan. Therefore, we carried out investigation of Salmonella-contaminated wet dog foods in Japan. We carried out this surveillance following the procedure of procedure of FAMIC in accordance with Pet Food Safety Law. Twenty domestic samples and forty-eight imported samples were examined. The countries of origins of imported foods and samples were including China (n=24), Australia (n=14), the United States of America (n=4), Thailand (n=4) and New Zealand (n=2) . We did not detect Salmonella from any samples. However, bacteria other than Salmonella were isolated from one sample manufactured by one company in a domestic wet food, and the bacteria were identified as Citrobacter freundii. Bacteria other than Salmonella were isolated from three samples produced by three companies in the imported wet food, and when these bacteria were identified, two were C. freundii and one was Stenotrophomonas maltophilia. Since the method adopted this study was aimed to detect Salmonella, it is not clear whatsoever. But it was possible that other bacteria could be detected by using other methods. Therefore, a more in-depth investigation will be needed in Japan. And producers of wet dog foods should reduce the potential for contamination with Salmonella and other bacteria.
