London, England - Researchers in London say your computer keyboard may be dirtier than your toilet. A consumer group tested 33 office keyboards for bacteria. They found four of them were potential health hazards. One of those four had five times the germs as one of the office’s toilet seats.

Keyboards pick up germs through sneezing and coughing. Also, workers who eat at their desk leave behind crumbs that become havens for bacteria. Workers not washing their hands after using the bathroom also contribute to the mess on the keyboard.

To keep your keyboard germ free, experts recommend shaking out all the crumbs and dust. Then wipe it off using a slightly damp lint-free cloth. You could also use an alcohol swab.

One microbiologist said that your keyboard is often a reflection of what’s in your nose and in your gut.
