Eggs are frequently implicated as a source of foodborne salmonellosis. In February 2009 an investigation was commenced following reports of gastrointestinal illness among diners at a Canberra restaurant. The investigation sought to confirm the existence of an outbreak, identify a source and implement public health measures to prevent more cases. Menus and booking lists were obtained from the restaurant and a case-control study was commenced. A suspected case was defined as a person who ate at the restaurant on 13 or 14 February 2009 and subsequently developed diarrhoea and/or vomiting. Twenty cases and 31 controls were enrolled in the study. Eating a tiramisu dessert containing raw egg had a highly statistically significant association with illness (crude odds ratio 130.50, 95% confidence interval 13.54-1605.28). Among the 20 cases, nine of 12 stool samples were positive for Salmonella Typhimurium phage type 170 (STm 170). No microbiological evidence of STm 170 was obtained from the restaurant or during the egg trace-back investigation. This report highlights the risk associated with consumption of foods containing raw or undercooked shell egg.
鸡蛋常被认为是食源性沙门氏菌病的一个源头。2009年2月，在堪培拉一家餐厅就餐的顾客出现胃肠道疾病报告后，展开了一项调查。该调查旨在确认疫情的存在，找出源头并实施公共卫生措施以防止更多病例出现。从餐厅获取了菜单和预订清单，并开展了一项病例对照研究。疑似病例定义为在2009年2月13日或14日在该餐厅就餐，随后出现腹泻和/或呕吐的人。该研究招募了20例病例和31名对照。食用含有生鸡蛋的提拉米苏甜点与疾病存在高度统计学显著关联（粗比值比130.50，95%置信区间13.54 - 1605.28）。在20例病例中，12份粪便样本中有9份鼠伤寒沙门氏菌170型（STm 170）检测呈阳性。在餐厅或鸡蛋溯源调查过程中未获得STm 170的微生物学证据。本报告强调了食用含有生的或未煮熟带壳鸡蛋的食品所带来的风险。
