A study by cleaning products company Kimberly-Clark Professional, which indicates that there are more germs in microwaves and company keyboards than in the toilet bowl .
To reach this conclusion, the researchers sampled 5,000 surfaces in law firms, insurance companies, factory offices, etc. And they analyzed these samples with a meter for levels of adenosine triphosphate (ATP) , a molecule found in all animals, plants, bacteria, yeasts and fungi. High levels of ATP are present in food or other organic residues that remain on certain surfaces. Thus, the more ATP is on a surface, the more likely it is to contain bacteria and viruses. Specifically, an ATP reading of more than 100 suggests that a surface needs a gentle cleaning. A place with a reading of 300 or more will be considered officially dirty and at high risk of spreading disease.
In offices, measures ATP exceeded the reading of 300 in faucets in kitchens and restrooms, doors microwave, computer keyboards, doors of refrigerators and buttons on vending machines for drinks and food .
