We report the first outbreak of salmonellosis caused by consumption of contaminated marlin mousse. Between 29 October and 5 November 2008, at least 53 persons developed diarrheal illness, all with a history of eating marlin mousse. Salmonella spp. that did not produce gas from glucose was isolated from stools of 26 affected patients and blood culture from one patient. Salmonella sp. isolates with the same phenotype were isolated in three samples of marlin mousse manufactured on 27 October 2008. The constituents of the mousse were smoked marlin, raw eggs, bovine gelatin, oil, and cream. A laboratory investigation of one sample of marlin mousse manufactured 3 days later, and the individual ingredients sampled a week after production of the contaminated batch were all negative for Salmonella. Serotyping and minimum inhibitory concentration determination were performed on 12 patient isolates related to the outbreak and two mousse isolates. All isolates belonged to Salmonella serovar Typhimurium and were pansusceptible to all antimicrobials tested. Pulsed-field gel electrophoresis revealed that all the isolates were indistinguishable, thus implicating the mousse as the vehicle of the outbreak.
我们报告了首例因食用受污染的马林鱼慕斯引发的沙门氏菌病疫情。2008年10月29日至11月5日期间，至少53人出现腹泻疾病，所有患者均有食用马林鱼慕斯的历史。从26名受影响患者的粪便和1名患者的血培养物中分离出不产生葡萄糖产气的沙门氏菌属。在2008年10月27日生产的三个马林鱼慕斯样本中分离出具有相同表型的沙门氏菌菌株。慕斯的成分包括烟熏马林鱼、生鸡蛋、牛明胶、油和奶油。对3天后生产的一个马林鱼慕斯样本以及在受污染批次生产一周后采集的各个成分进行的实验室调查，沙门氏菌检测均为阴性。对与此次疫情相关的12株患者分离株和2株慕斯分离株进行了血清分型和最低抑菌浓度测定。所有分离株均属于鼠伤寒沙门氏菌血清型，对所有测试抗菌药物均敏感。脉冲场凝胶电泳显示，所有分离株均无法区分，因此表明慕斯是此次疫情的传播媒介。
