平均分配在家庭厨房和浴室之间的14个地点每周监测粪便大肠菌群、总大肠菌群和异养平板计数细菌的数量。前10周为对照期，在第二个10周期间将次氯酸盐清洁产品引入家庭，并在最后10周期间使用次氯酸盐产品实施严格的清洁方案。厨房比浴室污染更严重，马桶座是污染最少的地方，所有三类细菌的最高浓度都出现在潮湿环境和/或经常接触的地方;这些地方包括海绵/抹布、厨房水槽排水区、浴室水槽排水区和厨房水龙头手柄。使用普通家用次氯酸盐产品实施清洁方案，导致这四个地点和其他家庭地点的所有三类细菌显著减少。
Fourteen sites evenly divided between the household kitchen and bathroom were monitored on a weekly basis for numbers of faecal coliforms, total coliforms and heterotrophic plate count bacteria. The first 10 weeks comprised the control period, hypochlorite cleaning products were introduced into the household during the second 10 weeks, and a strict cleaning regimen using hypochlorite products was implemented during the last 10 weeks. The kitchen was more heavily contaminated than the bathroom, with the toilet seat being the least contaminated site, The highest concentrations of all three classes of bacteria were found on sites that were moist environments and/or were frequently touched; these included the sponge/dishcloth, the kitchen sink drain area, the bath sink drain area, and the kitchen faucet handle(s). The implementation of a cleaning regimen with common household hypochlorite products resulted in the significant reduction of all three classes of bacteria at these four sites and other household sites.
