目的了解湛江市各类食品中常见食源性致病菌的污染情况,为食品安全风险评估及预警提供依据。方法 2011—2013年采用随机抽样的方法对湛江市9个县(市、区)具有代表性的监测网点(包括超市、农贸市场、餐饮业等)销售的各类食品进行抽样,按照《国家食源性致病菌监测网工作手册》提供的检测方法进行检测。结果 3年共抽取13大类食品752份样品,检出阳性样品65份,阳性率为8.64%,分离出食源性致病菌65株。检出率居前3位的食品分别为生食动物性水产品30.19%(32/106)、婴幼儿食品10.13%(8/79)、桶装饮用水9.09%(3/33)。检出率居前3位的致病菌分别为副溶血性弧菌27.36%(29/106)、蜡样芽胞杆菌11.67%(7/60)、铜绿假单胞菌9.09%(3/33)。餐饮业和农贸市场的检出率(14.04%和13.41%)高于超市(4.98%),差异有统计学意义(P<0.01);第2、3季度的检出率(13.94%和12.61%)高于第1、4季度(6.09%和5.22%),差异有统计学意义(P<0.05)。结论生食动物性水产品、婴幼儿食品以及桶装饮用水的食源性致病菌污染较为严重,今后要重点加强对这几类食品的卫生监督,夏秋季节重点加强对餐饮业和农贸市场的监督管理。
Objective To understand the pollution status of common food-borne pathogens in various kinds of food in Zhanjiang and provide the basis for food safety risk assessment and early warning. Methods From 2011 to 2013, a random sampling method was used to sample various types of foodstuffs sold in representative monitoring stations (including supermarkets, farmers’ markets, and catering industries) in 9 counties (cities and districts) of Zhanjiang City. According to the “ Source Pathogen Monitoring Network Manual ”to provide testing methods for testing. Results A total of 752 samples of 13 major food samples were collected during the three years. 65 positive samples were detected, the positive rate was 8.64%, and 65 foodborne pathogens were isolated. Among the top 3 food products, the detection rate was 30.19% (32/106) for raw food animals, 10.13% (8/79) for infant food and 9.09% (3/33) for bottled drinking water respectively. The pathogenic bacteria with the highest detection rate were 27.36% (29/106) of Vibrio parahaemolyticus, 11.67% (7/60) of Bacillus cereus, 9.09% (3/33) of Pseudomonas aeruginosa, . (14.04% and 13.41%) than the supermarket (4.98%), the difference was statistically significant (P <0.01). The detection rates in the second and third quarters (13.94% and 12.61% ) Was higher than the first and the fourth quarter (6.09% and 5.22%), the difference was statistically significant (P <0.05). Conclusions The food-borne pathogens of raw animal-based aquatic products, infant food and bottled drinking water are more serious. In the future, we should focus on strengthening the hygiene supervision of these types of food. In the summer and autumn, we will focus on intensifying the food-borne pathogens Supervision and management.
