Abstract：
Trichinellosis is a parasitic zoonotic disease transmitted through the consumption of meat from animals infected with Trichinella spp. nematodes. In North America, human trichinellosis is rare and is most commonly acquired through consumption of wild game meat. In July 2022, a hospitalized patient with suspected trichinellosis was reported to the Minnesota Department of Health. One week before symptom onset, the patient and eight other persons shared a meal that included bear meat that had been frozen for 45 days before being grilled and served rare with vegetables that had been cooked with the meat. Investigation identified six trichinellosis cases, including two in persons who consumed only the vegetables. Motile Trichinella larvae were found in remaining bear meat that had been frozen for >15 weeks. Molecular testing identified larvae from the bear meat as Trichinella nativa, a freeze-resistant species. Persons who consume meat from wild game animals should be aware that that adequate cooking is the only reliable way to kill Trichinella parasites and that infected meat can cross-contaminate other foods.
摘要：
旋毛虫病是一种寄生性人畜共患疾病，通过食用感染旋毛虫的动物的肉而传播。线虫.在北美,人类旋毛虫病是罕见的，最常见的是通过食用野生野味肉获得的。2022年7月，向明尼苏达州卫生部报告了一名疑似旋毛虫病的住院患者。症状发作前一周，病人和其他八个人分享了一顿饭，其中包括在烧烤之前冷冻了45天的熊肉，并配以与肉一起煮熟的蔬菜。调查发现了6例旋毛虫病，包括两个只吃蔬菜的人。在冷冻>15周的剩余熊肉中发现了活动旋毛虫幼虫。分子检测确定熊肉中的幼虫为毛毛虫，抗冻的物种。食用野生动物肉类的人应该意识到，充分的烹饪是杀死旋毛虫寄生虫的唯一可靠方法，受感染的肉类可以交叉污染其他食物。
