摘　　要：目的以福建省人群食用牡蛎引起副溶血性弧菌(VP)胃肠炎的风险为例,介绍一种快速的风险评估工具(sQMRA)在微生物定量风险评估中的应用。方法利用《2002年中国居民营养与健康状况调查》结果、文献报告和经验推断等方式,对福建省2008年9—11月牡蛎的消费量和零售阶段VP的污染水平、交叉污染和烹制对VP菌落数的影响等共11个参数进行了推算和引用。结果计算得到福建省2008年9—11月VP的感染人数为10 221人,其中有1 022人罹患VP胃肠炎,推算得到的VP胃肠炎的发病概率为2.8×10-5,与人群监测推算的VP胃肠炎发病概率3.8×10-5结果较为接近。结论 sQMRA是一种快速简便有效的微生物定量风险评估工具。Objective A swift quantitative microbiological risk assessment（sQMRA） tool was introduced as an example in the risk assessment of Vibrio parahaemolyticus（VP） gastroenteritis caused by comsuming oysters in Fujian province.Methods The database of Chinese national nutrition and health survey in 2002,paper reviewing and empirical inferring,11 parameters,such as the oyster consumption data and VP contamination level at retail,influence of cross-contamination and preparation on the number of colony forming unit of VP were estimated.Results It was calculated that about 10 221 and 1 022 people infected by VP and had gastroenteritis respectively during September to November in 2008.The estimated probability of VP gastroenteritis was 2.8 × 10-5 which was very close to that estimated based on the surveillance study,3.8 × 10-5.Conclusion The sQMRA is easy and appropriate for quick QMRA estimation.
