An outbreak of listeriosis in Denmark occurred in May 2009. Multilocus variable number of tandem repeats analysis typing, later confirmed by pulsed-field gel electrophoresis typing, showed that isolates from eight patients had identical patterns and were distinguishable from Listeria monocytogenes isolates from other Danish patients. Seven out of eight patients had received a meal with beef from the same meals-on-wheels delivery catering company 3 weeks prior to onset of disease. Two patients died of their infection. Large-scale delivery of precooked meals to a vulnerable population represents a threat if proper measures against listeriosis are not taken.
2009 年 5 月，丹麦暴发李斯特菌病疫情。多位点可变数目串联重复分析分型，随后经脉冲场凝胶电泳分型确认，显示 8 名患者的分离株具有相同的模式，与来自丹麦其他李斯特菌病患者的单增李斯特菌分离株不同。8 名患者中有 7 人在发病前 3 周食用了同一流动餐饮公司提供的含牛肉的餐食。2 名患者死亡。如果不采取适当的李斯特菌病防控措施，向弱势群体大规模配送预煮餐食存在威胁。
