Three cases of food poisoning after the consumption of raw deer meat occurred in Wakayama Prefecture on June 2, 2018. Sarcocystis truncata was detected in the raw deer meat, and we found that the agent expressed diarrhea-inducing 15 kDa protein similar to that of Sarcocystis fayeri. Among genus Sarcocystis, only S. fayeri is officially recognized as a causative agent of food poisoning by the Ministry of Health, Labour, and Welfare of Japan. The detected S. truncata has been shown to be strongly linked to the food poisoning, yet its causative agent was officially reported as unknown. There have been some reported diarrhea cases that seem to be related to raw deer meat contaminated with other Sarcocystis, such as Sarcocystis sybillensis and Sarcocystis wapiti. Our findings indicate that we should recognize any Sarcocystis species expressing the diarrhea-inducing protein as the causative agent of food poisoning after consumption of raw meat.
