BM0014 micrAlert Listeria is a selective medium for the detection, recovery, and isolation of Listeria species from cleaned, disinfected inanimate surfaces.
It should be used in conjunction with SW0006 micrAlert Neutraliser Swab Kit.
BM0014 micrAlert Listeria is based on Half Fraser Broth, developed in 1988 by Fraser
(1). Listeria monocytogenes is commonly found in soil, sewage, or faeces.
It is difficult to eradicate and can cause serious food poisoning.
L. monocytogenes is frequently tested for in food processing facilities to avoid contamination. Contamination can occur at all steps of the food manufacturing chain from raw materials to place of consumption. Confirmation that food processing surfaces are free from contamination with Listeria spp. after cleaning and disinfection is a critical step in preventing disease. Residual disinfectant actives may inhibit the growth of viable organisms preventing detection, so the neutralising agents contained in SW0006 micrAlert Neutraliser inactivate these residual disinfectants allowing improved recovery of sub-lethally damaged target organisms in BM0014 micrAlert Listeria.
