摘　　要：目的了解湖南省桶装饮用水卫生微生物污染状况,分析其饮用安全性。方法按国家饮用水检测标准方法对桶装纯净水、饮用水、矿泉水进行菌落总数、大肠菌群、致病菌、霉菌和酵母菌的实验室培养与检测,应用SPSS 15.0统计学软件分析不同饮用水总合格率之间的差异,并对抽检样品与送检样品的合格率进行比较。结果 147份桶装饮用水合格率为65.3%,不合格指标以菌落总数为主;2006-2009年不同饮用水之间总合格率差异有统计学意义(χ2=22.48,P<0.01);送检样品合格率为76.5%,高于抽检样品合格率51.5%,差异有统计学意义(χ2=10.1,P<0.05)。结论加大力度对桶装纯净水进行卫生监督监测工作,找出关键控制点,是抓好桶装饮用水卫生质量的关键。Objective To investigate the microorganisms in bottled drinking water,and to appraise the drinking security.Methods According to the related national standardized methods,the total number of colony,coliform bacteria,pathogenic bacterium,mould and yeast fungus in purified water,drinking water and mineral water were detected by laboratory tests.And then we compared the difference of the qualification ratio of the submitted samples and the sampling inspection samples with SPSS statistic software.Results The total qualification ratio of 147 samples was 65.3%,which was mainly caused by the index of total plate count.The qualification ratios of various drinking water were not equally and the there were statistically significant differences among them（χ2=22.48,P0.01）.The qualification ratio of the submitted samples was 76.5%,which was higher than that（51.5%） of the sampling inspection samples,and the difference was statistically significant（χ2=10.1,P0.05）.Conclusions Strengthening the health supervision of bottled drinking water will be benefit to enlighten the quality of drinking water.
