A British computer magazine has discovered that our computer keyboards could be bad for our health. “Which Computing” asked a laboratory to check 30 keyboards in its London office for bacteria(细菌). The results were shocking and disgusting. The lab scientists said five of the keyboards they tested put people at risk of illness. One keyboard contained 150 times more bacteria than health officials say is safe. Its test results showed it was five times dirtier than a toilet seat.
The researchers said the germs(病菌) they found could easily cause symptoms similar to food poisoning, such as diarrhoea(腹泻) and upset stomachs. They named these illnesses “QWERTY tummy” after the first six letters on the keyboard. The magazine recommended people clean their keyboards regularly to stay healthy and avoid stomach bugs.
The magazine said almost half the people they interviewed cleaned their keyboard less than once a month. Ten percent of people said they never cleaned it. Editor, Sarah Kidner, warned, “Most people don’t give much thought to the dirt that builds up on their PC. But if you don’t clean your computer, you might as well eat your lunch off the toilet.” The main causes of germs and bacteria are crumbs(食物碎屑) and other small pieces of food that drop onto the keys while workers eat at their desks. Oily fingers from eating potato chips and fries also attract bacteria.
Joanne Baxter, a secretary from West London, said she was shocked at this news. “I had no idea that my keyboard could make me ill. I’m afraid to find out what nasty things there are hiding under my keys,” she said.
