FDA更新李斯特菌疫情调查：编号1417疫情病例升至50例，涉事食品仍未确定
美国食品药品监督管理局（FDA）10月28日更新其食源性疾病疫情调查表：编号第1417号的单核细胞增生李斯特菌疫情病例数已由46例增至50例，涉事食品尚未确定，调查仍在进行中。
根据 FDA 公布的调查表，该疫情于2026年9月23日列入调查，目前尚未发起任何产品召回；FDA 已就该疫情启动溯源调查、现场检查与样本采集三项工作，以查明污染来源。
FDA 表示，认为自己出现食源性疾病症状的人，应联系医疗服务提供者与公共卫生官员，并告知发病前所吃过的食物，这些信息往往有助于查明新发或持续中的疫情来源。FDA 同时说明，未形成具体消费者行动建议的调查，未必能最终确定污染源或成因。
FDA Updates Listeria Outbreak Investigation: Cases in Outbreak Ref #1417 Rise to 50, Product Still Not Identified
The U.S. Food and Drug Administration (FDA) updated its foodborne illness outbreak investigation table on October 28: the case count for the Listeria monocytogenes outbreak listed as reference #1417 has increased from 46 to 50, the food product linked to the illnesses has not yet been identified, and the investigation remains active and ongoing.
According to the FDA table, the outbreak was first posted on September 23, 2026, and no recall has been initiated. FDA has initiated traceback, on-site inspection, and sampling work for this outbreak to identify the source of contamination.
FDA says people who think they have symptoms of foodborne illness should talk to their healthcare provider and public health officials and provide details of what they ate before becoming sick, which often helps solve emerging or ongoing outbreaks. The agency notes that investigations that do not result in specific, actionable steps for consumers may or may not conclusively identify a source or contributing factors.
