Novel outbreak-associated food vehicles (i.e., foods not implicated in past outbreaks) can emerge as a result of evolving pathogens and changing consumption trends. To identify these foods, we examined data from the Centers for Disease Control and Prevention Foodborne Disease Outbreak Surveillance System and found 14,216 reported outbreaks with information on implicated foods. We compared foods implicated in outbreaks during 2007–2016 with those implicated in outbreaks during 1973–2006. We identified 28 novel food vehicles, of which the most common types were fish, nuts, fruits, and vegetables; one third were imported. Compared with other outbreaks, those associated with novel food vehicles were more likely to involve illnesses in multiple states and food recalls and were larger in terms of cases, hospitalizations, and deaths. Two thirds of novel foods did not require cooking after purchase. Prevention efforts targeting novel foods cannot rely solely on consumer education but require industry preventive measures.

由于病原体不断变化和消费趋势的变化，可能会出现与疫情相关的新型食品载体（即与过去疫情无关的食品）。为了识别这些食物，我们检查了疾病控制和预防中心食源性疾病暴发监测系统的数据，发现了 14,216 起报告的暴发以及有关食物的信息。我们将 2007-2016 年爆发的食品与 1973-2006 年爆发的食品进行了比较。我们确定了 28 种新型食品载体，其中最常见的类型是鱼、坚果、水果和蔬菜；三分之一是进口的。与其他疫情相比，与新型食品车辆相关的疫情更可能涉及多个州的疾病和食品召回，并且在病例、住院和死亡方面更大。三分之二的新食品在购买后不需要烹饪。针对新食品的预防工作不能仅仅依靠消费者教育，还需要行业预防措施。
