Sanitary status of fresh-purified drinking water and its influencing factors in Kunshan City

目的了解昆山市现制现售水卫生状况及水质影响因素,为政府相关部门决策提供科学依据。方法对昆山建城区内现制现售水经营单位进行问卷调查,对现制现售水机器出水水质进行检测,通过logistic回归分析来探讨现制现售水质量主要影响因素。结果共调查售水机94台,11台机器出水不符合CJ 94-2005《饮用净水水质标准》,合格率为88.31%。水质是否合格的影响因素为机器安装地点周围是否存在污染源、机器防护门是否完整、水质过滤材料的更换和是否开展水质自检。结论法律法规的缺位、经营单位自身管理不到位成为影响现制现售水卫生安全的重要因素。建议由企业主导,政府、行业支持,从关键影响因素着手,制定合理、科学、规范的卫生管理制度和操作规范。
