摘　　要：目的掌握乐清市桶装饮用水卫生质量现状,并且对存在问题做原因分析,为监管部门下一步监督管理提供科学依据。方法随机抽取市场销售的桶装饮用水320份,按GB17324-2003、GB8537-2008、GB19298-2003规定的方法检测,检测项目有菌落总数、总大肠菌群、铜绿假单胞菌、pH值、电导率。结果 320份样品总合格率33.75%,饮用纯净水、天然净水、天然矿泉水合格率分别为25.6%、38.7%、96.8%,合格率之间差异有统计学意义(χ2=63.11,P<0.001)。通过QS认证的企业合格率为41.8%;未通过QS认证的企业合格率为23.8%,差异有统计学意义(χ2=11.502,P=0.001)。桶装饮用纯净水、天然净水菌落总数合格率合格率较低,分别为25.6%、45.2%。结论我市的桶装饮用水卫生状况令人堪忧,细菌菌落总数超标比较严重。另外通过QS认证的企业饮用水合格率明显高于未通过QS认证的企业,建议政府监管部门在继续要求未通过的企业进行认证的同时,也要加强对企业认证后的日常监督和检测。Objective To investigate yueqing bottled drinking water sanitary quality present situation, problems and to do cause analysis, provide a scientific basis for the supervision and administration of the next step to regulators Method We randomly selected bottled drinking water of 320, according to GB17324-2003, GB8537-2008, GB19298-2003 method specified detection. The test items include the total number of colonies, total coliform bacteria, pseudomonas aeruginosa, pH, conductivity. Results In total of 320 parts of the total sample 33.75 percent pass rate, clean drinking water, natural water, natural mineral water passing rates were 25.6%, 38.7%, 96.8%, respectively, the difference between the pass rate was statistically significant （x2=63.11, P〈0.001）. QS certified enterprise through a pass rate of 41.8%; does not pass through the QS certified companies was 23.8%, the difference was statistically significant （x2=11.502, P=-0.001）. Botded drinking water, natural water purification total number of colonies pass rate lower pass rate, 25.6%, 45.2%. Conclusion City of bottled drinking water health is worrying, and the total number of bacterial colonies exceeds seriously. Also drinking water through enterprise QS certification pass rate is significantly higher than that through the QS certification of enterprises. It suggests that government regulators should continue to require the unpass enterprise to get authentication, and should also strengthen the supervision and inspection of the daily business after certification.
