InSite L. mono Glo swab test for Listeria

InSite L. mono Glo is a single, safe and self-contained swab system for the simultaneous detection of Listeria species and Listeria monocytogenes. The results are read visually, and Listeria can be detected in as little as 24 h without the need for subculturing or further steps, eliminating cross-contamination risks.

An effective environmental monitoring program is the first line of defence to protect final product from Listeria contamination. Detecting down to less than 10 colony forming units of Listeria, the swab test enables users to monitor their environment with confidence.

InSite L. mono Glo is claimed to be more economical than outsource testing and Listeria contamination is detected days earlier, to allow for corrective action sooner, minimising the risk to finished product. The device uses a 5 cm sponge swab to maximise the recovery of Listeria from surfaces. The all-in-one device is designed to eliminate cross-contamination risks and avoid the need for separate sponges, diluents, bags and pipettes.

The device is easy to use — simply swab, snap and squeeze, incubate and read using the naked eye. A media colour change from yellow/amber to grey/black indicates a presumptive positive result for Listeria species. Samples presumptive for Listeria species that exhibit green fluorescence under ultraviolet light indicates a presumptive positive result for Listeria monocytogenes. No expensive equipment is required.

This is an AOAC-RI Performance Tested Method.
