目的了解2006—2013年深圳市市售食品中食源性寄生虫污染状况,为有效防治食源性寄生虫病提供科学依据。方法按照深圳市食品安全风险监测计划,随机采集淡水和海水类水产品、果蔬和沙拉等5类食品,分别采用消化法、浓缩集卵法等检测寄生虫囊蚴、幼虫和虫卵。结果共检测1 891份食品样品,检出寄生虫65份,检出率为3.44%。淡水类水产品检测623份,检出率为6.42%。其中淡水鱼检测567份,检出寄生虫39份,检出率为6.88%;鲩鱼的检出率最高达17.39%。检测淡水软体动物33份,在1份淡水螺中检出粪类圆线虫。检测海水类水产品309份,异尖线虫检出率为3.56%;其中带鱼的检出率高达13.51%。检测生食果蔬95份,检出率为8.42%。检测泡菜194份,检出率为1.03%。检测凉拌菜207份,检出率为1.93%。从肉类(426份)中未检出寄生虫或虫卵。结论深圳市部分市售食品受到寄生虫污染,应加强食品卫生宣教,改变人们不良的饮食习惯,避免感染。
Objective To understand the status of food-borne parasites in the commercially available foods in Shenzhen from 2006 to 2013 and provide a scientific basis for the effective control of food-borne parasitic diseases. Methods According to the food safety risk monitoring plan of Shenzhen, five kinds of freshwater and seawater aquatic products, fruits, vegetables and salads were randomly collected, and the metacercaria, larvae and eggs of parasites were detected by digestion and concentrated eggs collection respectively. Results A total of 1 891 food samples were detected and 65 parasites were detected with a detection rate of 3.44%. 623 freshwater aquatic products were detected, the detection rate was 6.42%. Among them, 567 freshwater fish were detected and 39 parasites were detected, the detection rate was 6.88%. The detection rate of mullet was up to 17.39%. 33 freshwater molluscs were detected, and Stool worms were detected in 1 freshwater snail. 309 seawater aquatic products were detected, the detection rate of Anisakis was 3.56%, and the detection rate of octopus was 13.51%. Detection of raw food 95 vegetables, the detection rate was 8.42%. 194 kimchi was detected, the detection rate was 1.03%. 207 cold dishes were detected, the detection rate was 1.93%. No parasite or eggs were detected from the meat (426). Conclusion Some of the commercially available foods in Shenzhen were polluted by parasites. Food hygiene education should be strengthened to change bad eating habits and avoid infection.
