There has been a decline in the number of human trichinellosis cases associated with consumption of commercial pork in the United States, while the relative importance of trichinellosis from game meats has increased. An investigation of an outbreak of trichinellosis in Idaho occurring after consumption of improperly prepared cougar jerky is described. Ten cases of trichinellosis were identified among 15 persons who ate the implicated meat. Viable Trichinella larvae were recovered from frozen cougar tissue. Polymerase chain reaction on parasite DNA yielded results consistent with genotypes T. nativa and Trichinella type T6. This report of cougar meat as a source of human trichinellosis and the finding of freeze-resistant Trichinella organisms in wildlife in Idaho extends the range of this genotype. Consumers of game need to cook the meat thoroughly, since even frozen meat may harbor viable Trichinella that can cause illness.
在美国，与食用商业猪肉相关的人类旋毛虫病病例数量有所下降，而来自野味的旋毛虫病的相对重要性有所增加。本文描述了对爱达荷州一起因食用未妥善处理的美洲狮肉干而引发的旋毛虫病疫情的调查。在食用了涉事肉类的15人中，确诊了10例旋毛虫病病例。从冷冻的美洲狮组织中发现了活的旋毛虫幼虫。对寄生虫DNA进行的聚合酶链反应结果与本地旋毛虫基因型和旋毛虫T6型一致。这份关于美洲狮肉作为人类旋毛虫病来源的报告以及在爱达荷州野生动物中发现抗冻旋毛虫生物体的情况，扩大了这种基因型的分布范围。野味消费者需要将肉彻底煮熟，因为即使是冷冻肉也可能含有能致病的活旋毛虫。
