Lab M Harlequin Chromogenic media for Listeria monocytogenes
Harlequin™ Listeria Chromogenic Agar (ISO) helps differentiate Listeria monocytogenes from other Listeria species
Recently released figures1 showing an increase in the incidence of listeriosis throughout Europe in 2009 illustrate the continuing need for comprehensive and highly effective methods of enriching and isolating Listeria species at all stages in food production. The figures show an increase in the number of listeriosis cases in humans by 19.1% compared to 2008, with 1,645 cases in 2009.
