Glad I’m not working in an Office anymore, even though my house probably isn’t that much cleaner with three kids attending daycare and school daily.

Researchers swabbed about 5,000 surfaces in office buildings, including law firms, insurance companies, healthcare offices, call centers and factories. The swabs were analyzed with a device that measures adenosine triphosphate (ATP), which is a molecule found in all animal, vegetable, bacteria, yeast and mold cells. High ATP levels are present in food or other organic residues left on surfaces. The more ATP found on a surface, the more likely it’s flourishing with bacteria and viruses. An ATP reading of over 100 suggests a surface could use a scrub-down. Readings of 300 or higher are considered officially dirty and at high risk for spreading illness.
