We describe the investigations and management of a outbreak of linked to consumption of pasteurised milk from a vending machine. Multiple locus variable number of tandem repeats analysis was newly used, confirming that detected in human cases was indistinguishable from that in a calf on the farm. This strengthened the evidence for milk from an on-farm vending machine as the source of the outbreak because of post-pasteurisation contamination. Bacteriological indicators of post-pasteurisation contamination persisted after the initial hygiene improvement notice. We propose that on-farm milk vending machines may represent an emerging public health risk.
我们描述了一起与饮用自动售货机巴氏消毒牛奶有关的爆发的调查和管理情况。多位点可变串联重复分析（MLVA）首次被应用，证实从人类病例中检测到的与农场小牛中的完全相同。由于巴氏消毒后的污染，这加强了农场自动售货机牛奶是此次爆发源头的证据。在最初的卫生改善通知后，巴氏消毒后污染的细菌学指标仍然存在。我们提出，农场牛奶自动售货机可能代表了一种新出现的公共卫生风险。
