Ben Cowling, an associate professor at University of Hong Kongs School of Public Health, told HK Magazine that a filtration system may remove bacteria, but could miss viruses, which tend to be smaller in size. 香港大学公共卫生学院副教授本-考林对《香港杂志》说,过滤系统能除去细菌,但除不掉比细菌体积更小的病毒。
Cowling also expressed another concern: If the staff need to frequently visit the toilet they may increase the risk of bringing other pathogens from the washroom into their food and drink preparation area. 考林还说了他另一个担忧:如果店员频繁进出卫生间,他们更有可能将病原体从厕所带到食品饮料准备区。
