On 23 May 2011, CDC identified a multistate cluster of Salmonella Heidelberg infections and two multidrug-resistant (MDR) isolates from ground turkey retail samples with indistinguishable pulsed-field gel electrophoresis patterns. We defined cases as isolation of outbreak strains in persons with illness onset between 27 February 2011 and 10 November 2011. Investigators collected hypothesis-generating questionnaires and shopper-card information. Food samples from homes and retail outlets were collected and cultured. We identified 136 cases of S. Heidelberg infection in 34 states. Shopper-card information, leftover ground turkey from a patient's home containing the outbreak strain and identical antimicrobial resistance profiles of clinical and retail samples pointed to plant A as the source. On 3 August, plant A recalled 36 million pounds of ground turkey. This outbreak increased consumer interest in MDR Salmonella infections acquired through United States-produced poultry and played a vital role in strengthening food safety policies related to Salmonella and raw ground poultry.
2011年5月23日,美国疾病控制与预防中心(CDC)确认了一起由海德堡沙门氏菌感染引发的跨州聚集性疫情,并从火鸡碎肉零售样本中分离出两株多重耐药(MDR)菌株,其脉冲场凝胶电泳图谱无法区分。我们将病例定义为在2011年2月27日至2011年11月10日期间发病的患者中分离出疫情菌株。调查人员收集了用于提出假设的调查问卷和购物卡信息。从家庭和零售商店收集了食品样本并进行培养。我们在34个州确认了136例海德堡沙门氏菌感染病例。购物卡信息、患者家中含有疫情菌株的剩余火鸡碎肉以及临床样本和零售样本相同的抗菌药物耐药谱都指向A工厂为源头。8月3日,A工厂召回了3600万磅火鸡碎肉。此次疫情增加了消费者对通过美国生产的家禽感染多重耐药沙门氏菌的关注,并在加强与沙门氏菌和生碎禽肉相关的食品安全政策方面发挥了重要作用。
