is a worldwide occurring apicomplexan parasite. Due to its high seroprevalence in livestock as well as in game animals, . is an important food-borne pathogen and can have significant health implications for humans as well as for pets. This article describes the prevalence of . in free-ranging macropods hunted for consumption. All hunted macropod species (commercial as well as non-commercial hunt) show a positive seroprevalence for . . This seroprevalence is influenced by various factors, such as sex or habitat. Furthermore, the parasite shows a high level of genetic variability in macropods. Genetically variable strains have already caused outbreaks of toxoplasmosis in the past (Canada and the US). These were attributed to undercooked game meat like venison. Despite this risk, neither Australia nor New Zealand currently have food safety checks against foodborne pathogens. These conditions scan pose a significant health risk to the population. Especially, since cases of toxoplasmosis have already been successfully traced back to insufficiently cooked kangaroo meat in the past.
是一种在全球范围内存在的顶复门寄生虫。由于其在牲畜以及野生动物中的血清阳性率很高,它是一种重要的食源性病原体,对人类和宠物的健康都可能产生重大影响。本文描述了在为食用而猎杀的自由放养的有袋目动物中该寄生虫的流行情况。所有被猎杀的有袋目动物物种(商业猎杀以及非商业猎杀)对该寄生虫的血清阳性率均为阳性。这种血清阳性率受多种因素影响,如性别或栖息地。此外,该寄生虫在有袋目动物中表现出高度的遗传变异性。过去,遗传变异菌株已在加拿大和美国等地引发弓形虫病疫情,这些疫情被归因于未煮熟的野味,如鹿肉。尽管存在这种风险,但澳大利亚和新西兰目前都没有针对食源性病原体的食品安全检查。这些情况可能对民众构成重大健康风险。特别是因为过去已经成功地将弓形虫病病例追溯到未充分煮熟的袋鼠肉。
