Raw milk cheeses are commonly consumed in France and are also a common source of foodborne outbreaks (FBOs). Both an FBO surveillance system and a laboratory-based surveillance system aim to detect Salmonella outbreaks. In early August 2018, five familial FBOs due to Salmonella spp. were reported to a regional health authority. Investigation identified common exposure to a raw goats' milk cheese, from which Salmonella spp. were also isolated, leading to an international product recall. Three weeks later, on 22 August, a national increase in Salmonella Newport ST118 was detected through laboratory surveillance. Concomitantly isolates from the earlier familial clusters were confirmed as S. Newport ST118. Interviews with a selection of the laboratory-identified cases revealed exposure to the same cheese, including exposure to batches not included in the previous recall, leading to an expansion of the recall. The outbreak affected 153 cases, including six cases in Scotland. S. Newport was detected in the cheese and in the milk of one of the producer's goats. The difference in the two alerts generated by this outbreak highlight the timeliness of the FBO system and the precision of the laboratory-based surveillance system. It is also a reminder of the risks associated with raw milk cheeses.
生乳奶酪在法国被广泛食用，也是食源性疾病爆发（FBO）的常见来源。FBO 监测系统和基于实验室的监测系统都旨在检测沙门氏菌爆发。2018 年 8 月初，向地区卫生当局报告了五起因沙门氏菌引起的家族性 FBO。调查确定了与食用一种生羊奶奶酪的共同暴露，该奶酪也分离出了沙门氏菌，导致国际产品召回。三周后，即 8 月 22 日，通过实验室监测发现全国范围内沙门氏菌纽波特 ST118 增加。同时，早些时候家族性病例的分离物被确认为 S.纽波特 ST118。对实验室确定的部分病例的访谈显示，他们接触了同一种奶酪，包括接触了之前召回中未包含的批次，导致召回范围扩大。此次疫情共影响 153 例病例，包括苏格兰的 6 例病例。在奶酪和其中一只生产者山羊的奶中都检测到了 S.纽波特。此次疫情产生的两种警报之间的差异突出了 FBO 系统的及时性和基于实验室的监测系统的精确性。这也提醒人们注意生乳奶酪相关的风险。
