Biokar COMPASS® Listeria Agar

​​

Biokar COMPASS® Listeria Agar is a chromogenic medium for the rapid detection and enumeration of Listeria monocytogenes and Listeria spp. in food and environmental samples. It differentiates L. monocytogenes by blue-green colonies with a distinct opaque halo, while other Listeria species form colonies without a halo. Validated to ISO 16140-2 and compliant with ISO 11290-1/-2 standards, it is a reliable solution for quality control and food safety testing.
