Telephones and computers are obvious locations.

There are also potentially serious health implications associated with using dirty equipment. Analysis of a keyboard normally reveals remnants of food and drink, hair, nails and lots of dead skin!

Recent research conducted by the University of Arizona has shown that telephones harbour up to 25,127 microbes per square inch, keyboards 3,295 microbes and computer mice 1,676.

Considering a toilet seat contains only 49 microbes per square inch you can now begin to see the real cost of not maintaining the cleanliness of your office equipment.
