First Case Report of Possible Sarcocystis truncata-induced Food Poisoning in Venison.

Along with the increase in consumption of raw animal meat, the prevalence of food poisoning is increasing. A 67-year-old Japanese man had eaten raw venison 4 hours prior to the beginning of vomiting. Many white cysts were discovered in the venison, with numerous bradyzoites being detected after the cysts were punctured. The presence of the Sarcocystis spp. 18S rRNA gene was detected by polymerase chain reaction, and Sarcocystis truncata was isolated from the venison. Sarcocystis truncata has not previously been identified in sika deer (Cervus nippon) in Japan. This is the first report of possible Sarcocystis truncata-induced food poisoning following consumption of venison.
