DuPont Qualicon BAX System Listeria assays

Food microbiologists can obtain next-day Listeria results with the DuPont Qualicon BAX System Listeria monocytogenes 24E and BAX System Genus Listeria 24E assays. The speed of these assays enables users to obtain a ‘yes’ or ‘no’ answer before products are released from the factory.

The BAX System Listeria 24E assays require a single 24 h enrichment step and have a common extraction protocol for all food types. With a performance comparable to conventional culture methods, these rapid PCR assays detect even low levels of Listeria and have been validated by AFNOR (QUA 18/06-07/08) for all human food products and environmental samples.

The samples are incubated in Oxoid 24 Listeria enrichment broth for 24 hours prior to a simple extraction protocol that requires no centrifugation steps. This is followed by analysis and automatic interpretation on the BAX System.
