Are you reading this at your PC? Maybe on a laptop? Or are you among the growing number of ‘mobile people’? Whatever device you are using to read this article…When was the last time you cleaned it? If you are at a desk, take a peek inside the keyboard…Do you see where I am going with this? According to a research study carried out by Queen Mary, University of London, 16% of phones had E. coli on them.

So apart from the food, the skin cells, the body fluids, the hair, and the dust, what else is hiding in there? It might surprise you to know that there are quite probably more germs in your keyboard than there are in the toilet.

Meet a few of the germs that can be found on your device

Bacteria on computer devices

If it makes you feel any better, take a look at the results we found in an office close to here!

Office Keyboard ATP Testing

We have focused on keyboards during our testing, but they are not the dirtiest places at work! According to a recent report published by Web MD, the six dirtiest places in your offices are:

  1. Tap handles in lavatories
  2. Microwave door handles
  3. Keyboards
  4. Refrigerator door handles
  5. Water fountain buttons
  6. Vending machine buttons

4,800 surfaces across a wide range of offices were tested by the researchers to obtain those results.
Have a look around you, are there nooks and crannies that simply don’t get cleaned? Surfaces that get overlooked? How thorough are the cleaning procedures in your business?

A busy day at the office

Generally speaking, what germs need to survive is similar to any species: food, moisture, warmth and time, all readily available at the office! Bacteria reproduce roughly every 20 minutes, E. coli tend to divide every 17 minutes, so in a 24 hour period one bacteria will divide exponentially to become billions in the right conditions. Start with one bacteria at 9 am in the office and use the equation below to see how many ‘colleagues he has’ by 9am the next day.

Have a go, you may need a calculator!

B = number of bacteria at the beginning of a time interval (1)
b = number of bacteria at the end of the time interval (?)
n = number of generations (number of times the cell population doubles during the time interval) (72)

b = B x (2 to the power of n)
