From the dust settles at the food debris and even dirt . The computer keyboards are high on the list of repositories of germs and bacteria to eliminate. To this are increasingly in demand for sanitation services . For fear of damage , computers are often overlooked by the companies office cleaning , avoiding a thorough cleaning between the keys.
A large study conducted by Ecoform , a leader in the field of sanitation and disinfection of the environment, together with Prof. Pastoni , President of the National Order of Biologists , found that the office desks have a high bacterial load , in addition, the microorganisms present are potentially pathogenic , meaning they are able to cause disease in humans.
On almost 4000 drawings made between desktop PCs , notebooks and phones , the most glaring is that desktops and laptops , as well as office phones have significant percentages of potentially pathogenic bacteria (67% and 69 % on phones and PCs ) and as if that were not enough , the indicators of fecal contamination have detected a massive presence of bacteria , respectively, 30% and 8 % on mobile keyboards .
To corroborate the finding Ecoform also Professor Charles Gerba , University of Arizona. What is clear is that lurk more bacteria in a keyboard of the computer that is in a tablet of a toilet and, consequently , the risk of infection is greater in the office rather than in a toilet . Main culprit in the dock is the snack consumed in their own workplace and poor personal hygiene.
These are the figures of the American research :
• toilet 49 bacteria / square inch = 7.60 bacteria/cm2 (rounded to 8 CFU/cm2 )
• Mouse 1676 b/p2 = 259.78 CFU/cm2 (260 CFU/cm2 )
• Keyboard 3295 = 510.73 b/p2 CFU/cm2 (511 CFU/cm2 )
• telephone 25127 b/p2 = 3894.69 CFU/cm2 ( 3895 CFU/cm2 )
