How well do you clean your bakery? And how effective is your process? If you’re looking for a way to improve your hygiene, you should run a ATP Test. Also known as rapid hygiene monitoring, it measures the effectiveness of cleaning activities and SSOPs performed on food-contact surfaces such as:
How does an ATP test work?
It measures the presence of adenosine triphosphate (ATP) — life’s energy carrying molecule within cells. And food residues, proteins and cells are rich in ATP. They undergo a bioluminescence process when they come in contact with luciferin–luciferase, resulting in light emission.
The intensity of the emitted light is measured with a device called a luminometer. This intensity is proportional to the amount of ATP produced and the level of microorganisms on the swabbed food surface. The ATP content of the sample correlates with the number of microorganisms present because all living cells have a specific amount of ATP.
How to run the test
To perform an ATP test, gather a pre-moistened swab, a food-contact surface, and an automated palm-sized bioluminescence device. Steps needed to complete an ATP assay are:
Remove swab from device
Swab a representative portion/area of a food-contact surface (or equipment)
Reinsert swab into body and screw down
Shake liquid down into bottom of clear tube and mix 2-3 times
Insert pocket swab into the instrument or device
Select swab site and press the run button to execute the counting or measurement

Starting with a BSc degree in Food Science & Technology at the Ohio State University, a MSc and PhD from the Department of Grain Science at Kansas State University. While working at Wendy’s and Dave’s Killer Bread, her technical teams experienced the lack of technical baking information on the internet. Seeing that this was not freely shared, Dr. Lin decided to launch BAKERpedia to cover this gap. With over 2 million pages read annually, BAKERpedia is the world’s only FREE and comprehensive online technical resource for the baking industry.
