1974年9月，疾病控制中心报告了有史以来最大的食源性沙门氏菌病爆发，影响了大约3400人，发生在纳瓦霍族印第安人保留地。致病因子是新港沙门氏菌，传播媒介是免费烧烤时提供给大约11000人的土豆沙拉。土豆沙拉的原料在不合适的温度下储存了16个小时。暴发的规模使我们能够通过计算暴发后2周内未参加烧烤的人的腹泻病发生率和检查暴发后获得的粪便培养结果来研究继发性传播。我们没有发现二次传播。我们的结论是，卫生官员应监测大型社交聚会上的食物准备和服务，沙门氏菌病的人际传播通常可能不会发生，即使在被认为极易交叉感染的环境中。
In September 1974, the largest outbreak of foodborne salmonellosis ever reported to the Center for Disease Control--affecting an estimated 3,400 persons--occurred on the Navajo Nation Indian Reservation. The responsible agent was Salmonella newport and the vehicle of transmission was potato salad served to an estimated 11,000 persons at a free barbecue. The cooked ingredients of the potato salad had been stored for up to 16 hours at improper holding temperatures. The magnitude of the outbreak allowed us to study secondary transmission by calculating the rates of diarrheal illness during the 2 weeks following the outbreak in persons who did not attend the barbecue and by examining the results of stool cultures obtained after the outbreak. We found no secondary transmission. We conclude that a health official should monitor food preparation and service at large social gatherings and that person-to-person transmission of salmonellosis probably does not normally occur even in settings considered highly conductive to cross-infection.
