从 20 世纪 70 年代开始，美国肠炎沙门氏菌血清型肠炎 (SE) 感染的发病率和相关疫情的数量急剧增加。到 1994 年，SE 是最常报道的沙门氏菌血清型，东北地区每 10 万人口中实验室确诊感染的发生率超过 10 例。深入的流行病学和实验室调查发现，带壳鸡蛋是人类 SE 感染的主要媒介，并且这些鸡蛋已被蛋鸡体内 SE 的跨卵巢传播所污染。旨在防止鸡蛋中SE污染和生长的三项关键干预措施包括以农场为基础的计划，以防止SE被引入产蛋鸡群、早期和持续冷藏带壳鸡蛋，以及对消费者和食品工人进行有关食用生鸡蛋或未煮熟鸡蛋风险的教育。自1996年以来，人类SE感染的发病率已大大下降，尽管由SE污染鸡蛋引起的许多病例和疫情仍在发生。
Beginning in the 1970s, the incidence of Salmonella enterica serotype Enteritidis ( SE) infection and the number of related outbreaks in the United States has increased dramatically. By 1994, SE was the most commonly reported Salmonella serotype, with an incidence of > 10 laboratory-confirmed infections per 100,000 population in the Northeast. Intensive epidemiologic and laboratory investigations identified shell eggs as the major vehicle for SE infection in humans, and that the eggs had been internally contaminated by transovarian transmission of SE in the laying hen. Three key interventions aimed at preventing the contamination and growth of SE in eggs have included farm-based programs to prevent SE from being introduced into egg-laying flocks, early and sustained refrigeration of shell eggs, and education of consumers and food workers about the risk of consuming raw or undercooked eggs. Since 1996, the incidence of SE infection in humans has decreased greatly, although many cases and outbreaks due to SE contaminated eggs continue to occur.
