Computing asked a microbiologist to examine for bugs on 33 keyboards in a typical London office, a toilet seat and a toilet door handle. 　　Four keyboards were judged potential health hazards and the microbiologist recommended the removal of one keyboard as it had 150 times the pass limit of bacteria -- five times filthier than the swabbed toilet seat. 　　Most people dont give much thought to the grime that builds up on their PC, but if you dont clean your computer, you might as well eat your lunch off the toilet, said Sarah Kidner, editor of Which? Computing in a statement. 　　The study found that eating lunch at desks is the main cause of a bug-infested keyboard. Dropped crumbs and food encourages the growth of millions of bacteria. 　　Poor personal hygiene, such as not washing hands after going to the toilet, may also add to the dirtiness of keyboards. 　　But despite the health hazard of a dirty keyboard, a survey of 4,000 people by the magazine found one in 10 people ever cleaned their keyboard while another two in 10 never cleaned their mouse. 　　Almost half -- or 46 per cent -- cleaned their keyboard less than once a month. 　　To clear out bugs, the magazine recommends users unplug keyboards, turn them upside down and shake them. 　　一项有关电脑键盘上细菌数量的必威体育精装版研究称，以后捡起落在键盘上的食物碎屑往嘴里塞之前可得想好了，这跟从马桶座上捡东西吃差不多。 　　这项研究由英国消费者杂志《Which? Computing》开展。该杂志让一位微生物学家对伦敦某办公室内的33个电脑键盘，一个马桶座和一个卫生间门把手进行细菌检测。 　　经检测发现，其中有四个键盘对人体健康存在潜在威胁。有一个键盘上的细菌数量超标150倍，比擦过的马桶座还要脏5倍，这位微生物学家建议将其从办公室搬走。 　　《Which? Computing》的编辑莎拉?德纳在一份声明说：“多数人都不太在意电脑
