COMPASS® Listeria Agar

ISO 16140-2 validated alternative method for the detection of Listeria monocytogenes and Listeria spp.
COMPASS® Listeria is a rapid alternative method used for the detection of Listeria monocytogenes and of Listeria
spp. in food products, and in environmental samples.
It features a single step of selective enrichment in Fraser ½ broth, followed by subculture onto COMPASS® Listeria
Agar. Enrichment can be performed at 37°C for 18 to 24 hours, or at 30°C for 22 to 28 hours.
This method is certified NF VALIDATION, according to the validation protocol NF EN ISO 16140-2 of 2016 for all
human food products and samples from the industrial production environment. The reference method used for the
validation is the standard NF EN ISO 11290-1 of 2017.

The method is certified NF VALIDATION, under Attestation N° BKR 23/02-11/02.

ISO 16140-2 validated alternative method for the enumeration of Listeria monocytogenes
The COMPASS® Listeria method is also used as a rapid alternative method for the enumeration of L. monocytogenes
in human food products and environmental samples, by surface or deep plating.

The method is certified NF VALIDATION, under Attestation N° BKR 23/05-12/07.
