Isolation of Salmonella spp. from Treats for Dogs

Post date:2019.06.13

Treats, which pet owners use to reward their pets for actions as instructed during training, are mostly half raw products made in Japan, and made from chicken, pork, beef, deer meat, horse meat, turkey, mutton.

Mr. Yukawa in Kurashiki University of Science and The Arts in Japan reported about the isolation of Salmonella spp. from treats for dogs in the 161st meeting of the Japanese Society of Veterinary Science. Salmonella spp. is one of the bacteria which are capable of causing not only food poisoning for humans, but also gastroenteritis accompanied by vomiting and diarrhea for dogs and cats. In the report, Salmonella spp. were isolated from 7 of 303 (2.3%) treats samples. Their serotypes were 3 strains of Salmonella O4:i:-, 2 strains of S. Rissen, and 7 strains of S. Thompson. The detection rate of Salmonella O4:i:- has been increasing in both humans and animals recently. Previously, S.Enteritidis had been mostly detected in human salmonellosis, accounting for 51.2% of strains isolated from 1994 to 1998 in Hokkaido, Japan, while Salmonella O4:i:- is getting attention as human salmonellosis because it was mostly detected from 2014 to 2015, accounting for 30.3%. These Salmonella spp. detected treats were made from chicken, pork, and beef, and 2 of them were made in Korea. In similar foreign research, it has also been reported that Salmonella spp. were isolated from 2 to 5% of samples.

Following the report, the Ministry of Agriculture, Forestry and Fisheries issued a notification about attention on Sept. 30, 2018. The notice showed points of consideration in the production of pet food, and asked to contact the Ministry of Agriculture, Forestry and Fisheries Livestock and Fisheries Safety Management Division promptly when health damage of dogs or cats caused by Salmonella-detected pet food had been confirmed. To avoid the risk of the contamination of these salmonella serotypes, which can infect humans, we need to wash hands carefully after touching treats with bare hands or treating pets’ excrement.
