A ten-fold increase in Salmonella Typhimurium DT104 cases in The Netherlands during September-November 2005 prompted an outbreak investigation. A population-based matched case-control study included 56 cases and 100 controls. Risk factors for infection were consumption of a pre-processed raw beef product (odds ratio 4.2, 95% confidence interval 1.5-12.0) and of food from mobile caterers (odds ratio 4.9, 95% confidence interval 1.1-22.1). Bacterial molecular typing established a link with another DT104 outbreak in Denmark caused by beef from a third European country. The incriminated beef was traced in The Netherlands and sampling yielded DT104 of the outbreak-associated molecular type. We concluded that this outbreak was caused by imported contaminated beef. Consumers should be informed about presence of raw meat in pre-processed food products. Optimal utilization of international networks and testing and traceability of foodstuffs has the potential to prevent foodborne infections.
2005年9月至11月期间，荷兰鼠伤寒沙门氏菌DT104病例增加了10倍，促使开展了一次疫情调查。一项基于人群的匹配病例对照研究纳入了56例病例和100名对照。感染的危险因素包括食用预处理生牛肉产品（比值比4.2，95%置信区间1.5 - 12.0）和食用流动餐饮商提供的食物（比值比4.9，95%置信区间1.1 - 22.1）。细菌分子分型确定此次疫情与丹麦另一起由来自第三个欧洲国家牛肉引起的DT104疫情有关。在荷兰追踪到了涉案牛肉，采样检测出与此次疫情相关分子型的DT104。我们得出结论，此次疫情是由进口受污染牛肉所致。应告知消费者预处理食品中存在生肉的情况。国际网络的优化利用以及食品的检测和可追溯性有预防食源性感染的潜力。
