Safety Data Sheet



Combine RAPID'L.mono Agar Base with RAPID'L.mono Supplement 1 and RAPID'L.mono and RAPID'Listeria spp. Supplement 2 to prepare highly selective plates for the discrimination and enumeration of Listeria monocytogenes and other Listeria spp. in human food products and environmental samples. Differentiation is obtained by the chromogenic detection of PI-PLC (phosphatidylinositol-specific phospholipase C) activity and the ability to ferment xylose. RAPID'L.mono Medium is validated for L. monocytogenes and Listeria spp. detection on the same plate.
