During December 1975 and January 1976, seventy-nine persons in Postville, Iowa, and nearby communities were infected with trichinosis by eating locally produced summer sausage made from a mixture of venison (provided by deer-hunting parties) and pork. More than 242 local residents and holiday visitors from five other states and Canada were exposed to the sausage, in which the venison was mixed in a 2:1 ratio with government-inspected and commercially obtained pork. Laboratory examinations of incriminated sausage samples showed one to 65 Trichinella larvae per 100 g and indicated that temperatures during processing had not exceeded 54 degrees C. Corrective measures centered on improving temperature monitoring during the smoking process at the sausage-preparation plant to ensure that adequate temperatures are achieved. Persons possessing the implicated sausage were advised to destroy it or to cook it adequately before eating it.
1975年12月至1976年1月期间，爱荷华州波斯维尔及附近社区的79人因食用当地生产的夏季香肠而感染旋毛虫病，这些香肠由鹿肉（由猎鹿团体提供）和猪肉混合制成。来自其他五个州和加拿大的242多名当地居民和度假游客接触了这种香肠，其中鹿肉与经政府检查并从商业渠道获得的猪肉按2:1的比例混合。对涉案香肠样本的实验室检测显示，每100克中有1至65条旋毛虫幼虫，表明加工过程中的温度未超过54摄氏度。纠正措施的重点是在香肠加工厂的熏制过程中加强温度监测，以确保达到足够的温度。拥有涉案香肠的人被建议销毁香肠或在食用前充分煮熟。
