Bottled purified water production and consumption process of the microbial contamination and influencing factors

目的探讨生产企业在生产、消费者饮用过程中造成桶装纯净水微生物污染及其影响因素,为生产企业规范管理、消费者合理正确使用桶装纯净水,提供科学依据。方法选取惠阳区内14家桶装纯净水生产企业及其每家15户消费者,通过对企业生产、消费者饮用过程中主要环节的现场卫生学调查及样品检测分析与研究,查找微生物污染及其影响因素。结果造成桶装纯净水微生物污染的影响因素主要有:1.生产企业从业人员操作不规范;桶、盖消毒不合格;灌装间空气污浊;桶盖密封差及水体消毒不合格;2.饮水机无定期消毒及储水时间过长。结论影响桶装纯净水受微生物污染是多因素的,既有生产企业的因素,又与消费者未合理、正确使用饮水机密不可分。
