ATP monitoring is a rapid testing method used by many companies to quickly assess the cleanliness of surfaces or liquid samples. Adenosine Triphosphate (ATP) is present in all organic material and is the universal unit of energy used in all living cells. ATP is produced and/or broken down in metabolic processes in all living systems. Processes such as photosynthesis in plants, muscle contraction in humans, respiration in fungi, and fermentation in yeast are all driven by ATP. Therefore, most foods and microbial cells will contain some level of naturally occurring ATP.
Hygiena luminometers (in conjunction with ATP swabs) use bioluminescence to detect residual ATP as an indicator of surface cleanliness. The presence of ATP on a surface indicates improper cleaning and the presence of contamination, including food residue, allergens and/or bacteria. This implies a potential for the surface to harbor and support bacterial growth.
ATP monitoring is used in food and beverage facilities to confirm that ATP presence is eliminated or minimized by effective sanitation procedures. ATP monitoring prevents cross-contamination, ensures product integrity, potentially improves product shelf life, protects brand reputation, and complies with regulatory requirements.
