中文摘要：本研究分析了三次食品中毒事件爆发的案例，这几次事件的起因与传播途径事先均未知。应用批量精确溯源分析法逐渐缩小问题食品的清单范围，最后筛选出问题源和传播途径。对食物流进行跟踪调查是突发食品安全事件调查的有效方法，尤其能协助识别易腐败或包含病毒的食品源。
外文摘要：Often, food-borne outbreaks cannot be clarified. One reason for this is that foods are no more available for testing once the outbreak is detected. Specifically, this can be the case for foods with a short shelf-life, such as plant foods. Moreover, sometimes the food matrix leads to performance failures of laboratory methods. In such situations, investigational tracing can be the key to outbreak clarification. The analysis of food flows in supply chains can display epidemiological correlations, show the extent of events and may allow rapid outbreak containment. This article presents three examples of outbreaks where the causative agent and/or the transmitting vehicle were unknown. Batch-precise traceability studies first helped to narrow down the list of questionable foods and later to identify the causative vehicles and their sources. Investigational tracing of food flows is a powerful tool for rapid outbreak clarification and specifically helpful for causative foods that are easily perishable and/or contaminated with viruses.
