A robust hygiene verification program is at the heart of any ATP food safety programme. Progressive, proactive facilities develop Standard Operating Procedures (SOPs) that formalise their cleaning and hygiene test process.
Validation and verification of the facility’s SOPs can be accomplished through a robust hygiene monitoring programme. To help with this, Neogen® offers a range of products to detect the amount of residue or organic matter, including bacteria, yeast and mould, left on a surface or in rinse water after cleaning.
Neogen’s ATP test system leads the industry and provides a near-instant measurement of organic material left on a surface. Hygiene swab tests, such as protein swabs can also provide a relatively quick measurement of general cleaning by reporting the amount of protein left on the surface. While ATP systems report a numeric value, protein detection swabs change colour in the presence of proteins.
Another important indicator of SOP efficacy is the relative presence of microorganisms on the surface. While also affected by the cleaning portion of the SOP, this marker relates more closely to the efficacy of the sanitiser.
AccuClean Advanced delivers industry-leading speed and sensitivity for determining the cleanliness of food contact surfaces and equipment through residual protein detection. AccuClean Advanced is a simple, 10-second visual test that reveals detected protein residue through an easy-to-interpret colour change. With a detection limit of 10 μg protein per sample, the ATP test provides sensitive, reliable results.
AccuPoint Advanced Hygiene Verification System measures the ATP collected from food contact surfaces or rinse water samples as an indication of the cleanliness of the surface or purity of the rinse water. Approved by the AOAC Research Institute, AccuPoint Advanced was found to perform according to the manufacturer’s documented claims and can be used throughout the global marketplace and within the regulatory arena. The system works by measuring the light created when ATP reacts with liquid stable enzyme chemical reagents in the system’s unique sampling devices. The higher the levels of food residue and microorganisms in a surface or rinse water sample, the more ATP, and the more light produced.
