Toxoplasma gondii infections are common in humans and animals worldwide. The ingestion of food or water contaminated with oocysts excreted by infected cats or ingestion of uncooked or undercooked meat containing tissue cysts of T. gondii are the 2 major modes of transmission of T. gondii. Deer are a popular game. Recently, outbreaks of clinical toxoplasmosis were reported in humans in North America linked to ingestion of undercooked venison. Here, we review prevalence, persistence of infection, clinical disease, epidemiology, and public health risks of T. gondii infections in deer and other cervids for the past decade. Estimates of worldwide serological prevalence are summarized individually for each species of deer, elk, moose, and caribou. Genetic diversity of 112 viable isolates of T. gondii from cervids is discussed, including its public health significance. Prevalence of T. gondii in deer is very high. Any part of a deer, including liver, spleen, and muscles, should be cooked thoroughly before human consumption.

弓形虫感染在世界范围内的人类和动物中都很常见。食物或水的污染，通过感染的猫或含有的组织囊肿未煮过的或煮熟的肉的摄取排泄出的卵囊的摄取弓形虫是变速器的2种主要模式弓形虫。鹿是一种流行的游戏。最近，据报道，在北美，与未煮熟的鹿肉的摄入有关的人中爆发了临床弓形虫病。在这里，我们回顾了弓形虫的流行，感染的持续性，临床疾病，流行病学和公共卫生风险在过去的十年中，鹿和其他子宫颈感染。每种鹿，麋鹿，驼鹿和北美驯鹿的全球血清学流行率估计值分别进行了总结。讨论了112种来自弓形虫的弓形虫可行菌株的遗传多样性，包括其公共卫生意义。鹿中弓形虫的患病率很高。鹿的任何部分，包括肝脏，脾脏和肌肉，在食用之前都应彻底煮熟。
