对海白中副溶血性弧菌(Vibrio parahaemolyticus,简称Vp)做半定量风险评估,包括危害识别、污染检测、居民膳食调查及Risk ranger半定量风险评估。膳食调查采用食物频率法,以问卷的方式得到三亚居民食用海白的比例为80%及食用频率为1月1次;污染检测主要3月、4月份期间从三亚第一市场和荔枝沟市场取样,采用GB/T 4789.7-2008法对样品进行检测,检出率为100%并得到两个市场的平均污染量分别为1.65 log10MPN/g,2.63log10MPN/g;最终用Risk ranger得到三亚市售海白的副溶血性弧菌膳食风险为高风险(风险指数为51),三亚海白消费者感染副溶血性弧菌胃肠炎的概率为2.96×10-6(人·d)-1;每年消费污染了副溶血性弧菌的海白所引发的病例数约为740.5人。
A semi-quantitative risk assessment of Vibrio parahaemolyticus (Vp) was conducted, including hazard identification, contamination testing, dietary surveys of residents and semi-quantitative risk assessment of risk ranger. Meal survey by food frequency method, by way of questionnaire Sanya inhabitants to eat sea white ratio of 80% and consumption frequency of January 1; the main pollution detection in March and April from Sanya first market and the market of litchi ditch sampling , Using GB / T 4789.7-2008 method for testing the sample, the detection rate was 100% and the average pollution of the two markets were 1.65 log10MPN / g, 2.63log10MPN / g; White Vibrio parahaemolyticus dietary risk is high risk (risk index of 51), Sanya Haitai consumers infected with Vibrio parahaemolyticus gastroenteritis probability of 2.96 × 10-6 (person · d) -1; annual Consumption of polluted Vibrio parahaemolyticus caused by the number of cases was about 740.5 people.
