目的全面了解聊城市托幼机构的消毒质量,为进一步加强托幼机构的消毒技术指导提供科学依据。方法采用现场随机采样及实验室检测的方法,于2011—2012年连续2年对聊城市已注册的各类型托幼机构进行分层随机抽样并对检测结果统计分析。结果 2011—2012年共采集室内空气、工作人员手、物体表面、餐(饮)具、饮水机水、紫外线灯管辐照强度共计908份样品,合格770份,总合格率为84.80%。其中2011及2012年的合格率分别为76.94%、91.33%;城乡托幼机构消毒监测合格率分别为89.98%、77.89%;公私托幼机构消毒监测合格率分别为91.39%、74.84%,差异有统计学意义(均P<0.01)。结论连续2年的监测结果显示,该市托幼机构的消毒质量有明显提高趋势。但城乡、公立和私立托幼机构之间的消毒质量有显著性差异,应重点加强对其托幼机构的消毒监督及管理工作。
Objective To comprehensively understand the disinfection quality of nurseries in Liaocheng and provide scientific basis for further strengthening the disinfection technical guidance of nurseries. Methods By means of on-site random sampling and laboratory tests, stratified random sampling was conducted for all kinds of kindergartens registered in Liaocheng City for two consecutive years from 2011 to 2012, and statistical analysis of test results was carried out. Results A total of 908 samples of indoor air, staff’s hands, object surface, meal (drinking) set, water dispenser and UV lamp were collected during 2011-2012, with a passing rate of 770 and a total pass rate of 84.80%. Among them, the passing rates in 2011 and 2012 were 76.94% and 91.33% respectively; the qualification rates of disinfection monitoring in urban nurseries and child-rearing institutions were 89.98% and 77.89% respectively; the passing rates of disinfection and monitoring in public and private nurseries were 91.39% and 74.84% respectively, Statistical significance (all P <0.01). Conclusion The monitoring results for two consecutive years show that the quality of disinfection in kindergartens and nurseries in this city has been significantly improved. However, the quality of disinfection between urban and rural areas, public and private kindergartens is significantly different, and disinfection supervision and management of nurseries should be strengthened.
