目的通过对食品经营场所高风险专间内紫外线灯安装使用情况和消毒效果进行分层比较分析,反映紫外线灯与该类场所的卫生状况之间的关系。方法对食品经营场所高风险专间中空气和操作台面的微生物指标进行监测,同时调查该专间内紫外线灯安装使用情况。结果共监测78家食品经营场所84间高风险专间中空气和操作台面的微生物指标,其中细菌总数合格率分别为52.4%和73.8%,紫外线灯安装符合率仅为11.9%,消毒效果随着紫外线灯安装符合卫生要求程度的提高而提高。结论如何合理使用紫外线灯,提高紫外线灯安装使用符合率,对改善食品经营场所卫生状况有重要意义。
Objective To stratify the comparative analysis of the installation and use of UV lamps and the disinfection effects in the high risk specialty food business establishments to reflect the relationship between the UV lamps and the hygiene conditions of such places. Methods The microbiological indexes of air and operating countertops in high-risk specialty food premises were monitored, and the installation and usage of UV lamps in this special room were investigated. Results Microbiological indexes of air and worktops in 84 high-risk specialty rooms were monitored in 78 food establishments. The qualified rate of total bacterial count was 52.4% and 73.8% respectively. The compliance rate of UV lamp installation was only 11.9% UV lamps installed in line with the requirements of health improvement and increase. Conclusions How to use UV lamp reasonably and raise the compliance rate of UV lamp installation and use is of great significance to improve the sanitary status of food premises.
