During 1975-2012, CDC surveillance identified 1,680 trichinellosis cases in the United States with implicated food items; among these cases, 1,219 were attributed to consumption of raw or pork products, and 461 were attributed to nonpork products. Although trichinellosis in the United States has historically been associated with consumption of pork, multiple nonporcine species of wild game also are competent hosts for Trichinella spp. and have been collectively implicated in the majority of trichinellosis cases since the late 1990s (1-4) (Figure 1). During July 2016-May 2017, the Alaska Division of Public Health (ADPH) investigated two outbreaks of trichinellosis in the Norton Sound region associated with consumption of raw or undercooked walrus (Odobenus rosmarus) meat; five cases were identified in each of the two outbreaks. These were the first multiple-case outbreaks of walrus-associated trichinellosis in Alaska since 1992 (Figure 2). Health care providers should inquire about consumption of commercially prepared and personally harvested meats when evaluating suspected trichinellosis cases, especially in areas where consumption of wild game is commonplace.
1975年至2012年期间，美国疾病控制与预防中心（CDC）的监测发现，在美国有1680例旋毛虫病病例涉及相关食品；在这些病例中，1219例归因于食用生猪肉或猪肉制品，461例归因于非猪肉制品。尽管在美国，旋毛虫病历来与食用猪肉有关，但多种非猪类野生动物也是旋毛虫属的适宜宿主，自20世纪90年代末以来，大多数旋毛虫病病例都与它们有关（1-4）（图1）。2016年7月至2017年5月期间，阿拉斯加公共卫生部门（ADPH）调查了诺顿湾地区两起与食用生的或未煮熟的海象（海象属）肉有关的旋毛虫病疫情；两起疫情各发现5例病例。这是自1992年以来阿拉斯加首次出现多例与海象相关旋毛虫病的疫情（图2）。在评估疑似旋毛虫病病例时，医疗服务提供者应询问患者是否食用过商业加工的和个人收获的肉类，特别是在食用野生动物很常见的地区。
