Computer keyboards are germ dumps
The British consumer magazine Which? Computing commissioned a microbiologist to examine 33 keyboards, a toilet seat and a toilet door handle, in a typical London office for bugs generally found in unhygienic places.
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, which means 5 times filthier than the swabbed toilet seat.
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.
