Listeria monocytogenes is a pathogenic bacteria which can cause serious food poisoning. For the detection of Listeria monocytogenes, conventional methods are long and they require heavy work load. On the contrary, the medium CHROMagar Listeria helps to easily differentiate Listeria monocytogenes from other Listeria directly at the isolation step. Listeria monocytogenes colonies are blue and are surrounded by a white halo due to a specific phospholipase activity.

CHROMagar Listeria method combines a single enrichment step (Fraser 1/2 24h at 30ºC) followed by isolation of 100µl on CHROMagar Listeria.
Detection of absence of L.monocytogenes can be done in 24h after growth on CHROMagar Listeria while suspected colonies can be confirmed by a single test designated CHROMagar Identification Listeria, thus positive samples can be detected within 3 days.
