The results of a 3-year study of trichinosis in British Columbia wild-life, based on the testing of more than 9,000 tissue specimens from a large variety of animal species, indicated that trichinosis is widespread among wild mammals in the southern and central parts of British Columbia. This continuing survey has established that the disease is carried by at least 15 species of terrestrial mammals including 3 species of rodents. The finding of Trichinella spiralis in ground squirrels and nonsynanthropic mice may be the first reported in North America. Although trichinosis appears to be eradicated in domestic pigs in British Columbia, a sylvatic cycle of the disease continues to exist independently and poses a potential threat to human health. It is possible for human beings to contract trichinosis by consuming inadequately cooked meat from certain wildlife species, especially bears, as well as meat products (such as pork or beef sausage) to which game meat has been added; several local outbreaks were caused by this source. Another hazard of unknown potential is the spread of trichinosis from the wild animal reservoir--from rodents in particular--to domestic pigs and thus to man.
一项针对不列颠哥伦比亚省野生动物旋毛虫病的为期3年的研究结果表明，旋毛虫病在不列颠哥伦比亚省南部和中部的野生哺乳动物中广泛存在。该研究基于对来自多种动物物种的9000多个组织样本的检测。这项持续进行的调查证实，至少有15种陆生哺乳动物携带这种疾病，其中包括3种啮齿动物。在北美，首次在草原犬鼠和非伴人鼠中发现旋毛虫。虽然旋毛虫病在不列颠哥伦比亚省的家猪中似乎已被根除，但该病的野生动物传播循环仍然独立存在，并对人类健康构成潜在威胁。人类有可能因食用某些野生动物（尤其是熊）未煮熟的肉以及添加了野味肉的肉制品（如猪肉或牛肉香肠）而感染旋毛虫病；当地曾发生过几起因这种来源导致的疫情。另一个潜在风险未知的危害是旋毛虫病从野生动物宿主，特别是从啮齿动物传播到家猪，进而传播给人类。
