Live poultry-associated salmonellosis is an emerging public health issue in the United States. Public and animal health officials collaborated to investigate one of the largest (356 cases, 39 states) of these outbreaks reported to date. A case was defined as illness in a person infected with the outbreak strain of Typhimurium with illness onset between 1 March and 22 October 2013. The median patient age was seven years (range: < 1-87 years); 58% of ill persons were children ≤ 10 years, 51% were female, 25% were hospitalized; 189 (76%) of 250 patients reported live poultry exposure in the week before illness; and 149 (95%) of 157 reported purchasing live poultry from agricultural feed stores. Traceback investigations identified 18 live poultry sources, including 16 mail-order hatcheries. Environmental sampling was conducted at two mail-order hatcheries. One (2.5%) of 40 duplicate samples collected at one hatchery yielded the outbreak strain. Live poultry are an important source of human salmonellosis, particularly among children, highlighting the need for educational campaigns and comprehensive interventions at the mail-order hatchery and agricultural feed store levels. Prevention and control efforts depend on a One Health approach, involving cooperation between public and animal health officials, industry, health professionals, and consumers.
与活禽相关的沙门氏菌病是美国一个新出现的公共卫生问题。公共卫生官员和动物卫生官员合作，对迄今为止报告的此类最大规模疫情之一（356例病例，涉及39个州）展开调查。病例定义为感染鼠伤寒暴发菌株、发病时间在2013年3月1日至10月22日之间的患者。患者年龄中位数为7岁（范围：<1 - 87岁）；58%的患者为10岁及以下儿童，51%为女性，25%住院治疗；250名患者中有189名（76%）报告在发病前一周接触过活禽；157名报告从农业饲料店购买过活禽的患者中有149名（95%）如此。追溯调查确定了18个活禽来源，包括16个邮购孵化场。在两个邮购孵化场进行了环境采样。在其中一个孵化场采集的40份重复样本中有1份（2.5%）检测出暴发菌株。活禽是人类沙门氏菌病的一个重要来源，尤其是在儿童中，这凸显了在邮购孵化场和农业饲料店层面开展教育活动和全面干预措施的必要性。预防和控制工作依赖于“同一健康”方法，即公共卫生官员和动物卫生官员、行业、卫生专业人员及消费者之间的合作。
