Taenia saginata cysticercosis causes financial losses to the beef industry and farmers, and represents a significant source for human infection in many countries. A case-control study was conducted to identify risk factors for bovine cysticercosis on farms in Switzerland. The case group (n=119) consisted of farms with infected cattle identified at slaughter in 2005 and 2006. Infections were confirmed by morphological or molecular diagnosis. The control group (n=66) comprised randomly selected farms with cattle slaughtered in the same period but with no evidence or history of infection. In personal structured interviews with the farmers, information regarding local surroundings and farm management was collected. Logistic regression revealed the following 5 factors as being positively associated with the occurrence of bovine cysticercosis: the presence of a railway line or a car park close to areas grazed by cattle, leisure activities around these areas, use of purchased roughage and organized public activities on farms attracting visitors. This information is considered useful for government authorities to direct control strategies as well as for farmers to take measures tailored to local situations.
牛带绦虫囊尾蚴病给牛肉产业和养殖户造成了经济损失，并且在许多国家是人类感染的一个重要来源。开展了一项病例对照研究，以确定瑞士农场牛囊尾蚴病的风险因素。病例组（n = 119）由2005年和2006年在屠宰时发现有感染牛的农场组成。感染通过形态学或分子诊断得到确认。对照组（n = 66）由同期随机选择的有牛被屠宰但无感染证据或感染史的农场组成。在对养殖户进行的结构化个人访谈中，收集了有关当地环境和农场管理的信息。逻辑回归显示，以下5个因素与牛囊尾蚴病的发生呈正相关：靠近牛放牧区域有铁路线或停车场、这些区域周边的休闲活动、使用购买的粗饲料以及农场有吸引游客的有组织公共活动。这些信息被认为对政府当局指导控制策略以及养殖户采取因地制宜的措施很有用。
