摘要
目的对深圳市水产品进行监测与分析,了解当地水产品污染状况。方法2006-2008年,在深圳市餐饮单位、肉菜综合市场和超级市场采集鲜活鱼、贝壳类等331份水产品进行重金属、农药、致病菌、贝类毒素、肝吸虫等项目的检测,并依据相关标准进行卫生学评价。结果2006-2008年,淡水鱼类的污染率分别为8.62%、3.09%、20.19%;综合3年结果,324份淡水鱼中,副溶血性弧菌超标18份,铅超标9份,亚硝酸盐超标3份;污染率较高的鱼种主要有鲩鱼28.13%、桂花鱼25.93%。在2006年检测的7份贝类样品中,尚未检出贝类毒素超标。综合2007-2008年结果,鲜活水产品中,肝吸虫囊蚴污染率依次为:鲩鱼20.00%、福寿鱼17.14%、鲫鱼12%。结论深圳市水产品存在不同程度的致病菌、重金属、化学物质或肝吸虫囊蚴污染,应加强水产品养殖、销售和消费环节的卫生监管和指导,减少生食水产品,确保消费者食品安全。
Objective To monitor and analyze the hygienic status of aquatic products in Shenzhen in order to understand the pollution of aquatic products. Method 331 aquatic samples including fish,shellfish and other aquatic products were collected by random from restaurants,fairs and supermarkets in Shenzhen from 2006 to 2008. Hygienic evaluation was based on the results of testing items including heavy metals,pesticides,pathogenic bacteria,clonorchis sinensis and Vibrio parahaemolyticus etc. Results The pollution rates of aquatic products were 8. 62% ,3. 09% and 20. 19% in 2006,2007 and 2008 respectively. The main pollutant items were vibrioparahaemolyticus,lead and nitrite,and the qualified rates of main polluted fish breeds were 28. 13% in grass carp,25. 93% in freshwater grouper. The contents of shellfish toxin were not exceeded the standards in 7 samples. The pollution rates of clonorchis sinensis were high,20. 00% in grass carp, 17. 14% in tilapia and 12% in crucian.
