And people think blogging is a safe job. A microbiologist working for Which? Magazine has found keyboards with 150 times the recommended limit of bacteria. It was also five times as filthy as a toilet seat swabbed at the same time.

The main cause appears to be eating lunch at your desk and filling it with crumbs, which encourage the growth of bacteria. The design of keyboards creates nice warm spaces safe from disturbance and easy cleaning, except the occasional pounding down; it would be interesting to find out if the bacteria count is higher under the tilde key than under the e or a. Another source may be from not washing your hands after going to the toilet.

I just banged my ergonomic keyboard upside down on my desk and was appalled at the amount that came out. ::Guardian and Which?
