2018—2019年六安市公共场所用品用具微生物监测分析

Microbiological Tests of Public Articles and Appliances in Public Places of Lu’an City,China,2018—2019

目的分析六安市公共场所用品用具微生物监测结果,评价该市公共场所卫生水平,为今后卫生监管提供依据。方法2018—2019年对六安市公共场所用品用具微生物检测情况进行监测,分析不同公共场所公共用品用具微生物检测项目的样品合格率差异。结果2年共检测公共用品用具4109份,合格3949份,样品合格率为96.11%,2018和2019年样品合格率分别为95.32%和96.91%,差异有统计学意义(P<0.05)。住宿和理发美容样品合格率分别为96.46%(2865/2970)和95.17%(1084/1139),差异无统计学意义(P>0.05)。按公共用品用具分类,6类公共用品用具差异有统计学意义(P<0.01)。毛巾、茶具和理发工具类的公共用品用具合格率较低,分别为77.53%(414/534)、83.73%(139/166)和84.38%(54/64)。按样品分类,监测的公共用品用具中,理发工具和茶具类的两年总样品合格率较低,分别为94.76%和94.55%,不同类型公共用品用具两年总样品合格率差异有统计学意义(P<0.01)。细菌总数,大肠菌群和金黄色葡萄球菌样品合格率分别为94.49%(617/653),98.17%(964/982)和98.88%(616/623),差异有统计学意义(P<0.05)。结论六安市公共场所用品用具微生物卫生状况较好,但毛巾、茶具和理发工具类样品合格率较低,今后应加强这类物品的卫生监测和卫生指导,提高卫生质量。

Objective To investigate the result of microbiological tests of public articles and appliances in public places of Lu’an City,China,to evaluate the hygiene level of public places in this city,and to provide a basis for future hygiene supervision.Methods An investigation was performed for the microbiological test result of public articles and appliances in the public places of Lu’an City from 2018 to 2019 to analyze the differences in the pass rates of samples of public articles and appliances from different public places.Results A total of 4109 public articles and appliances were tested in the 2 years,among which 3949 were qualified,with a pass rate of 96.11%.The pass rates of samples in 2018 and 2019 were 95.32%and 96.91%,respectively,with a significant difference between the two years(P<0.05).The pass rates of accommodation and hairdressing samples were 96.46%(2865/2970)and 95.17%(1084/1139),respectively,and there was no significant difference between the two groups of samples(P>0.05).According to the classification of public articles and appliances,there were significant differences in pass rates between the six types of public articles and appliances(P<0.01).Towels,tea sets,and hairdressing tools had relatively low pass rates of 77.53%(414/534),83.73%(139/166),and 84.38%(54/64),respectively.Among the public articles and appliances monitored,hairdressing tools and tea sets had relatively low 2-year pass rates of 94.76%and 94.55%,respectively,and there was a significant difference in 2-year pass rate between different types of public articles and appliances(P<0.01).The pass rates of total bacterial count,coliform,and Staphylococcus aureus were 94.49%(617/653),98.17%(964/982),and 98.88%(616/623),respectively,with a significant difference(P<0.05).Conclusion Articles and appliances in public places of Lu’an City have good hygiene status,while towels,tea sets,and hairdressing tools tend to have low pass rates,and therefore,hygiene supervision and guidance for such articles should be strengthened to improve hygiene quality.
