中文摘要:

      目的 检测宿迁市市售包装饮用水中大肠菌群和铜绿假单胞菌的污染情况。方法 按照GB 4789.3-2010(第二法)和GB/T 8538-2008对市场上抽取的包装饮用水样品进行大肠菌群和铜绿假单胞菌的检测。对检测数据使用SPSS软件进行差异显著性分析, 对市售包装饮用水中大肠菌群和铜绿假单胞菌的污染情况以及两者的检出情况与产品包装规格的相关性进行分析。结果 抽检的86份样品中有4份样品检出大肠杆菌, 检出率为4.65%, 22份样品检出铜绿假单胞菌, 检出率为25.58%, 检出大肠菌群、铜绿假单胞菌为阳性的样品均为桶装包装饮用水。大肠菌群的检出率与铜绿假单胞菌检出率之间存在极显著差异(x2=7.340, P=0.007)。结论 宿迁市包装饮用水存在安全隐患, 食品监管部门应加强监督管理, 切实保障消费者健康。

英文摘要:

      ObjectiveTo detect the contamination situations of coliform bacteria and Pseudomonas aeruginosain packaged drinking waterin the markets of Suqian city. MethodsAccording to GB4789.3-2010 (the second method) and GB/T 8538-2008,the coliform bacteria and Pseudomonas aeruginosa in packaged drinking water samplesweredetected., and the significant differences of data were analyzed by SPSS software. The contamination situations of coliform bacteria and Pseudomonas aeruginosain samples and the correlation between detection results of the above 2 indexes and packaging specifications of product were analyzed. Results Thecoliform bacteria were detected in 4 samples from 86 samples, thePseudomonas aeruginosawere detected in 22 samples, and the detection rates were 4.65% and 25.58%, respectively. All positive samples were bottled packaging drinking water. There was a significant difference between the detection rates of coliform bacteria and Pseudomonas aeruginosa(x2=7.340, P=0.007). Conclusion There are hidden safety risks in packaged drinking water of Suqian city, and the food regulatory departments should strengthen supervision and management, so as to effectively protect the health of consumers.
