General Information:

Listeria monocytogenes is a pathogenic microorganism belonging to the Listeria genus. The bacterium poses a threat for immunocompromised people or pregnant women. It can survive under refrigerated temperatures. Foods that have not been subject to heat treatment are especially at risk of being contaminated by Listeria and have been involved in Listeria outbreaks in the past.

On the medium, the colonies of Listeria monocytogenes will show a characteristic colour staining in comparison to other Listeria. Compact Dry LM can be used for enumeration and also for the detection of Listeria monocytogenes from a pre-enrichment.

Compact Dry LM is ready-to-use. No equipment for media preparation is necessary.


  • Different colouration for presumptive Listeria monocytogenes and Listeria spp.
  • Ready-to-use plate: no media preparation and no equipment for media preparation necessary (time saving).
  • Simple storage: temperature range 1 – 30 °C; long shelf-life in comparison to agar plates.
