New Solutions by Neogen to Detect Listeria spp., L. mono
Neogen has developed a simplified, sensitive method to detect both Listeria spp. and Listeria monocytogenes utilizing only one sample enrichment broth and one agar plate.
Neogen’s new NF-certified One Broth One Plate workflow can be used to test all food and environmental samples, and provides results in as little as 48 hours — with enhanced sensitivity versus ISO 11290 methodology. The workflow has received NF validation/AFNOR certification (NEO: 35/06-07/16; NEO: 35/05-07/16).
The primary enrichment in the One Broth One Plate workflow is Acumedia’s LESS Plus media, a highly selective enrichment broth for the detection of Listeria spp. Manufactured using the highest quality dehydrated culture media (DCM), LESS Plus medium is compliant to ISO 9001:2008.
The workflow’s agar plate utilizes Listeria Chromogenic Agar (LCA), which is a selective medium that is formulation compliant to ISO 11290-1:2014 according to Ottaviani and Agosti, and performance compliant to ISO 11133:2014. By utilizing both chromogenic and phospholipase enzyme reactions, the media allows for easy identification and differentiation of both L. monocytogenes and Listeria spp. on one plate.
Neogen can supply the LCA media fully ready to use as part of Lab M’s Pinnacle™ pre-poured media range, which includes all necessary supplements with no need to weigh, cool or autoclave media. Alternatively, the LCA media is available in DCM format, with additional supplements required, as part of Lab M’s Harlequin™ chromogenic media range.
