Salmonella food poisoning has been one of the most predominant problems on etilogical agent in Japan as well as on Okinawa island. In livestock, Salmonella research hasn't done except domestic fowls for its difficulty. It's the Nitta's reports that we can find serological survey for Salmonella infections of feral mammals on Okinawa island. In order to the safety of livestock is increased, this survey investigates the relations of Salmonella infections livestock and feral mammals. There were isolated 41 samples of Salmonella. The O group we can find particularly in Okinawa. Serovar was S.Oranienburg, S.Weltevreden, S.Unfantis, S.Typhimurium and S.Enteritidis. S.Oranienburg was isolated from the cow first. But unfortunately we couldn't see the relations of salmonella infection between feral mammals and livestock. S.Enteritidis was isolated from Mongoose. S.Weltevreden was isolated from Roof rat. S.Infantis and S.Typhimurium were isolated from Asian house shrew. Salmonella isolated from livestock couldn't be cause of Salmonella isolated from feral mammals. But we considered that farmer should do health control, preventive intrusion to livestock shed of feral mammals, and cleaning livestock shed.沖縄島において、本実験では家畜と畜産施設周辺で捕獲された野生動物を対象としてサルモネラの保有状況を調査し、外来動物であるマングースをはじめとする野生動物と家畜のサルモネラ伝搬に関するリスクを評価した。その結果、家畜から検出されたサルモネラの血清型と野生動物のサルモネラの血清型の間に直接的な感染経路は確認されなかったが、家畜に病原性を持つ血清型（Enteritidis, Typhimurium）が野生動物から確認されたので、野生動物によるサルモネラ伝搬の可能性が示唆される結果となった。
