ATP Systems are used to measure cleanliness to determine hygiene and cleaning effectiveness. While there are a number of ATP systems on the market, AccuPoint® Advanced is the only one which has been rigorously tested and validated by AOAC, an independent testing and approval organisation. This approval is unique, because it sets a standard by which all other systems will be judged.
AOAC International is a globally recognised, 501(c)(3), independent, third party, not-for-profit association and voluntary consensus standards developing organisation founded in 1884. When analytical needs arise within a community or industry, AOAC International is the forum for finding appropriate science-based solutions through the development of microbiological and chemical standards. AOAC standards are used globally to promote trade and to facilitate public health and safety.
How Did We Do It?
The process began in early 2015 with the submittal of a validation outline to the AOAC. This was the first time an ATP sanitation verification system was submitted for approval. The AccuPoint Advanced system was validated according to the AOAC Research Institute policies and procedures. The validation has two main parts: Method Developer Studies and the Independent Laboratory Study. Method Developer Studies include pure analyte LOD, matrix and microbial LOD, inhibition, lot-to-lot consistency and stability, instrument variation and robustness testing. The Independent Laboratory Study includes pure analyte and matrix LOD testing.
The comprehensive study took 17 months to complete and resulted in the formal approval of the AccuPoint Advanced Sanitation Verification System on September 9, 2016. Excerpts from the study are contained below.
Principle of the Method
The AccuPoint Advanced test system utilises an ATP‐induced chemiluminescence reaction to determine the cleanliness of test samples. ATP is a chemical compound found in all living cells, including bacteria, yeast and mould, and food debris. Chemiluminescence is a chemical reaction that produces light. ATP chemiluminescence occurs when ATP from a sample comes into contact with luciferase, an enzyme found in fireflies, and luciferin, a substrate (1). The amount of light emitted in this reaction is proportional to the amount of ATP detected in a sample.
Discussion of the Study
The performance validation of the AccuPoint Advanced Hygiene Verification System produced results that support kit claims in providing a useful way to monitor the effectiveness of hygiene programs. Collectively, the results in this validation report provide evidence that the AccuPoint Advanced Hygiene Verification System produces consistent and reliable data for evaluating sanitation program effectiveness on stainless steel surfaces in food processing and food services facilities.
Why Did We Do It?
Neogen® Corporation believes that it’s critical for companies in the food safety industry to have accurate and unbiased information. This is especially important when it comes to claims made about products designed to protect consumers and the companies that produce food or beverage products.
Each time we receive a validation from an independent third party on any of our tests, it provides further assurance to the food production and processing industry that our tests perform as expected. The performance of our AccuPoint Advanced system in recent independent evaluations by AOAC and NSF International validates the investment we have made in their development. We developed the product with the goal of creating a new hygiene verification system that is superior to anything else on the market.
Why are independent evaluations and approvals important?
Independent evaluations by recognised evaluation bodies offer the best way for a prospective customer to judge an ATP system. AOAC and NSF International are well recognised, credible, independent authorities in the food safety industry. Both studies focused their validation efforts on utilising the systems as they’re used in the real world. The results speak for themselves.
