micrAlert Salmonella

micrAlert Salmonella

SKU: BM0015 Category:

BM0015 micrAlert Salmonella is a selective enrichment media for the isolation of Salmonella spp. from cleaned, disinfected inanimate surfaces.
It should be used in conjunction with SW0006 micrAlert Neutraliser Swab Kit.

BM0015 micrAlert Salmonella is designed to indicate the presence of Salmonella spp. on previously cleaned and disinfected surfaces. Salmonella spp. are frequently tested for on food processing surfaces to ensure the effectiveness of the cleaning/disinfection regimen and reduce the risk of food contamination. Salmonellae can decarboxylate lysine resulting in production of cadaverine, an alkaline amine capable of overcoming acid produced by fermentation thus maintaining a higher pH in the medium.

Residual disinfectant actives may inhibit the growth of viable organisms preventing detection, so the neutralising agents contained in SW0006 micrAlert Neutraliser are designed to inactivate these residual disinfectants allowing improved recovery of sub-lethally damaged target organisms using BM0015 micrAlert Salmonella.
