本文讨论了1981年3月23日和24日在马斯特里赫特举行的欧洲首脑会议期间由印第安纳州沙门氏菌引起的沙门氏菌病的暴发。据估计，在1000-1200名接触者中，有600-700人患病。暴发的原因可能是一种用于各种零食和冷盘的沙拉基料。在准备这种沙拉基料的过程中出现了严重的错误，使得产品中存在的S·印第安纳菌大规模繁殖(每克107株)。南印第安纳州的原始来源从未得到证实。疫情造成了相当大的经济后果。医疗费用估计为40,000法郎，病假费用在200,000至500,000法郎之间，餐饮公司的经济损失约为500,000法郎(1981年汇率：1美元=2.33法郎)。政府当局用于调查疫情的时间估计为150个工日。3月28日星期六，为欧洲首脑会议提供食物的公司提供了家庭聚餐和冷饮自助餐。作为预防措施，所有的准备工作都由食品检验局的一名检查员监督。尽管如此，31人再次成为印第安纳州沙门氏菌病的受害者。在准备食物过程中采集的30份食物样本中，有5份对印第安纳州S。然而，由于在食用前严格控制时间和温度，好氧平板计数和肠杆菌科平板计数非常低(分别为每克104和102)，感染剂量也是如此。一项对厨房条件的调查显示，尽管厨房看起来很干净，但它受到了印第安纳葡萄球菌的高度污染；在采集的70份环境样本中，有16份对印第安纳葡萄球菌呈阳性。因此，交叉污染是不可避免的。据推测，在欧洲峰会期间，在准备受感染的沙拉底料并将其添加到各种菜肴中时，厨房受到了污染。峰会暴发的受害者表现出的严重症状和第二次暴发的低感染剂量表明，所涉及的S·印第安纳州比沙门氏菌的毒力更强。
This paper discusses the outbreak of salmonellosis caused by Salmonella indiana during the European Summit Conference in Maastricht on 23 and 24 March 1981. It is estimated that 600-700 of the 1000-1200 exposed persons became ill. The cause of the outbreak was probably a salad base which was used in various snacks and cold dishes. Serious errors were made during preparation of this salad base which allowed the S. indiana present in the product to multiply on a large scale (107 per gram). The original source of the S. indiana was never established. The economic consequences of the outbreak were considerable. Medical costs were estimated at Fl.40,000, costs due to sick leaves between Fl.200,000 and Fl.500,000 and economic loss to the catering firm at approximately Fl.500,000 (exchange rate 1981: U.S.$1 = Fl.2.33). The time devoted to investigating the outbreak by government authorities was estimated at 150 man-days. On Saturday, 28 March, the company which had supplied the food for the European Summit Conference provided the catering for a family dinner and a cold buffet. As a precaution all the preparations were supervised by an inspector from the Food Inspection Service. In spite of this, 31 people again fell victim to salmonellosis caused by S. indiana. Of 30 food samples taken during preparations of the meals, 5 were positive for S. indiana. The aerobic and Enterobacteriaceae plate counts were however very low (< 104 and < 102 per gram, respectively) as were the infective doses, owing to very stringent control of timing and temperature before consumption. An investigation into conditions in the kitchen showed that although it looked clean it was highly contaminated with S.indiana; 16 of the 70 environmental samples taken were positive for S. indiana. Cross contamination was therefore inevitable. It is presumed that the kitchen became contaminated whilst the infected salad base was being prepared and added to various dishes during the European Summit Conference. The serious symptoms displayed by the victims of the Summit outbreak and the low infective doses in the second outbreak suggest that the S. indiana involved was more virulent than is usual for Salmonella.
