An outbreak of 538 cases of trichinellosis occurred in France in December 1993. Seven cases developed neurotrichinosis and 23 had cardiologic complications. No deaths were recorded. Two patients had a positive muscle biopsy showing living Trichinella larvae. One of them was typed as Trichinella spiralis. A case-control study showed that horse meat was the only meat associated with illness (odds ratio = 80.7). The risk of illness increased with the amount of horse meat eaten and when it was consumed raw. The cases, which were spread out in five foci, bought horse meat from five butchers who had received parts of a single horse carcass imported in November 1993 from Canada. The Trichinella International Screening Program, implemented since 1985 after two similar episodes involving a thousand cases, failed to detect the incriminated horse carcass. This new horse meat-related outbreak led to modifications of the internationally recommended screening methods whereby the weight of meat samples tested was increased.
1993年12月，法国爆发了538例旋毛虫病疫情。7例发展为神经型旋毛虫病，23例出现心脏并发症。无死亡病例记录。两名患者肌肉活检呈阳性，显示有活的旋毛虫幼虫。其中1例被鉴定为旋毛形线虫。一项病例对照研究表明，马肉是唯一与疾病相关的肉类（比值比=80.7）。患病风险随着马肉食用量的增加以及食用生马肉而上升。这些病例分布在五个疫点，病例是从五名屠夫那里购买的马肉，这些屠夫收到了1993年11月从加拿大进口的一匹马的部分胴体。自1985年在两起涉及一千例病例的类似事件后实施的旋毛虫国际筛查计划，未能检测出涉案的马胴体。这次新的与马肉相关的疫情导致对国际推荐的筛查方法进行了修改，增加了检测肉样的重量。
