IS IT REALLY CLEAN? ATP testing is a way to check that it is.
WHAT IS ATP TESTING? ATP (Adenosine Triphosphate) is present in all animal, vegetable, bacteria, yeast and mould cells. Detection of ATP indicates the presence of contamination by any of these sources. Everyday objects with an ATP reading of 300 or higher are considered to have a high risk for illness transmission. Using a Hygiena SystemSURE II™ ATP Meter, a device commonly used to monitor sanitary conditions in industry, hygienists swabbed the objects to measure levels of Adenosine Triphosphate (ATP)
HOW IS ATP TESTING DONE?
Measurement of ATP requires only a few minutes and is based upon the firefly luciferase bioluminescence assay.
The properties of the ATP assay are well suited to determinations of cleanliness, with cleanliness being defined as the absence of organic (derived from life) material. Clean surfaces have no ATP, while dirty surfaces have ATP and perhaps live microbial cells. The result of an ATP test that is available in minutes permits the immediate assessment of the sample condition and whether additional cleaning action is required. The traditional method of determining cleanliness is the aerobic plate count. This test requires 2 days to complete. This procedure is limited in the type of microorganisms it can detect and does not detect organic residue.
Simply swab a 10cm square area of the surface, place in the Hygiena SystemSURE II™ ATP Meter and wait 15 seconds for indicative results.

We believe cleaners should be asked to regularly and thoroughly clean touch points. Doesn’t it make sense to CLEAN> PROTECT and PREVENT bacteria and mould from putting your assets at risk? We designed our invisible sealers to make this process easy and or we can conduct a Touch Point Health Check so you can see what the cleaners may regularly miss .
These are ATP test results from a recent field study conducted in Sydney Australia in May/ June/July 2013
“People do not realize the amount of contamination they are exposed to going to work each day and doing everyday things like filling their gas tank or riding on an escalator,” said Dr. Charles Gerba, Professor of Microbiology at the University of Arizona. “This new testing is compelling because it underscores the importance of hand and surface hygiene. Most cold and flu viruses are spread because people touch surfaces in their immediate area and then touch their faces, other objects and other people. Washing and drying your hands frequently throughout the day, can help prevent your risk of getting sick or spreading illness around the office.”
A national ’touch point’ cleanliness survey you will find interesting.
The testing was conducted by trained hygienists in high traffic locations in Atlanta, Chicago, Dallas, Los Angeles, Miami and Philadelphia. Using a Hygiena SystemSURE II™ ATP Meter, a device commonly used to monitor sanitary conditions in industry, hygienists swabbed the objects to measure levels of Adenosine Triphosphate (ATP). ATP is present in all animal, vegetable, bacteria, yeast and mold cells. Detection of ATP indicates the presence of contamination by any of these sources. Everyday objects with an ATP reading of 300 or higher are considered to have a high risk for illness transmission. In all, more than 350 separate swabs were taken and analyzed.
The percentage of public surfaces tested and found to have high levels of contamination (an ATP count of 300 or higher), includes:
- 71 percent of Gas Pump Handles
- 68 percent of Mailbox Handles
- 43 percent of Escalator Rails
- 41 percent of ATM Buttons
- 40 percent of Parking Meters/Kiosks
- 35 percent of Crosswalk Buttons
- 35 percent of Vending Machine Buttons
