As food manufacturers and processors recognize the importance of the microbiological environmental hygiene monitoring as part of good manufacturing practices, the need for a cost effective, easy-to-use, fast and accurate method to assess environmental sampling has become increasingly essential. All four systems utilize an identical test principle Bacteria are recovered from the surface of food manufacturing or processing equipment using a pre-moistened swab, which is capable of neutralizing commonly employed detergents and sanitizers. The sample swab is then transferred into an organism specific media (swabs have a convenient break point so are easily deposited into the growth media). Once incubated, any target organism will be identified with the simple colour change.
