On may 1994, a foodborne outbreak took place in Almazora (Castellón, Spain) after a meal with 116 persons. A sanitary study was made to find out the causes and control the outbreak.
Inspection of the setting and a case-control study were carried out. Several foods and faecal specimens of 23 patients were investigated. We also study the effect of alcohol on the occurrence of the outbreak.
A hundred people was interviewed (86%), 58 ill persons. Salmonella enteritidis was isolated from faeces and statistically implicated food (odds ratio = 75, IC 95 = 15.6-361), a sandwich with tuna, boiled eggs and vegetables. Among adults, epidemiological analysis showed a protective effect of alcohol, adjusted for age, sex and consumption of the implicated food (p = 0.007).
In the study of foddborne outbreaks by Salmonella enteritidis simultaneous consumption of alcoholic drinks and foods should be taken into account to explain some exposed non-cases.
1994年5月，西班牙卡斯特利翁省阿尔马索拉市116人聚餐后发生了一起食源性疾病暴发事件。开展了一项卫生学研究以查明病因并控制疫情。
进行了现场检查及病例对照研究。对23名患者的多种食物和粪便样本进行了调查。我们还研究了酒精对疫情发生的影响。
对100人（86%）进行了访谈，其中58人患病。从粪便中分离出肠炎沙门氏菌，经统计学分析该菌与一种食物有关（优势比=75，95%置信区间=15.6 - 361），这种食物是夹有金枪鱼、煮鸡蛋和蔬菜的三明治。在成年人中，经年龄、性别及相关食物摄入量校正后的流行病学分析显示酒精具有保护作用（p = 0.007）。
在研究肠炎沙门氏菌引起的食源性疾病暴发时，应考虑酒精饮料与食物同时食用的情况，以解释一些暴露但未发病的情况。
