摘　　要：【目的】研究上海市金山区海产品牡蛎中副溶血性弧菌的污染现状,并对其可能引发的风险进行评估,为相关部门提供防控依据。【方法】2017年7—10月采用随机抽样的方法在金山区农贸市场、超市、餐饮店中随机采集带壳未加工牡蛎样品40份,参照国家标准检测方法检测牡蛎中副溶血性弧菌含量,并结合2012—2013年上海市金山区居民膳食与健康状况监测结果,应用Risk Ranger软件进行半定量风险评估分析。【结果】40份牡蛎样品中副溶血性弧菌的总体阳性检出率为80.0%(32/40)。以农贸市场检出率最高为85.7%(12/14),其次是餐饮饭店和超市。生食牡蛎,副溶血性弧菌污染的风险分值为63,属于高风险,预计消费者患病的概率为6.85×10~(-4),预计金山区居民每年因生食牡蛎感染副溶血性弧菌致病的发病率为1 247.8/10万。【结论】金山区海产品牡蛎中副溶血性弧菌污染情况较严重。生食海产品牡蛎为高风险,建议消费者减少或不生食牡蛎。食用牡蛎前有效加工是降低副溶血性弧菌食源性疾病发生的有效方法,同时进一步加强海产品流通环节的监测和管理。[Objective]To investigate the prevalence of Vibrio parahaemolyticus(VP)in oysters in Jinshan District,Shanghai and make assessment on the risks that may cause,providing the basis for prevention and control of foodborne disease.[Methods]Raw oyster samples with shells were randomly collected from markets,supermarkets and restaurants in Jinshan District from July to October in 2017.The content of VP in oysters was tested in accordance with the national standard methods.The semi-quantitative risk assessment for VP in oysters was made by Risk Ranger combining with the monitoring results of diet and health status of residents in Jinshan District of Shanghai in 2012-2013.[Results]The overall positive rate of VP in the 40 oyster samples was 80.0%(32/40).The positive rate of VP in oyster samples from farmer’s markets was the highest,85.7%(12/14),followed by those from restaurants and supermarkets.The relative risk for VP in raw oysters was 63.The probability of illness caused by VP in oysters per day per consumer of interest was 6.85×10-4,and the total predicted patients annual incidence rate in this population was 1247.8/105.[Conclusion]The contamination of VP in seafood oysters in Jinshan District is serious.Eating raw oysters is at high risk;consumers are advised to reduce or avoid eating raw oysters,and processing food before eating is an effective method to decrease VP infection.Strengthening surveillance and management is imperative in this regard.
