目的纸币的反复使用易受到细菌的污染,可能对人体健康造成危害。本研究目的是了解广州市市面流通纸币的卫生状况,为进一步加强其管理与保洁、消毒工作提供科学依据。方法对广州市内商铺,银行进行纸币的随机抽样共371张(来自银行80张,非银行291张),进行表面菌落总数的测定和纸币表面致病菌检出率的测定,用SPSS13.0软件对测定结果进行统计分析。结果研究结果显示各种面值的纸币表面菌落总数为164.33cfu/cm2,来源于银行的322.22cfu/cm2,非银行的75.97cfu/cm2,大肠埃希菌、金黄色葡萄球菌和绿脓杆菌的检出率分别为84.0%,16.0%,3.3%。结论银行和非银行的纸币污染状况差异有统计学意义(P<0.05),大肠埃希菌污染率高提示受污染严重,对病菌的传播有重要的意义。
The repeated use of purpose banknotes is easily contaminated by bacteria and may cause harm to human health. The purpose of this study is to understand the health status of circulating paper money in Guangzhou and to provide a scientific basis for further strengthening its management, cleaning and disinfection. Methods A total of 371 banknotes (from 80 banks and 291 non-banks) were randomly sampled from shops and banks in Guangzhou to determine the total number of surface colonies and the detection rate of pathogen on the surface of banknotes. SPSS13.0 The software carries on the statistical analysis to the determination result. Results The results showed that the total number of colonies on the surface of banknotes of various denominations was 164.33cfu / cm2, which was 322.22cfu / cm2 from the bank, 75.97cfu / cm2 from the non-bank, and that of the Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa The rates were 84.0%, 16.0% and 3.3% respectively. Conclusion The banknotes of banknotes were significantly different from banknotes (P <0.05). The high contamination rate of E.coli suggested that it was seriously polluted and had important significance for the spread of germs.
