Persistent Listeria that find a harborage site in food facilities can significantly increase the risk of broader contamination. Presence/absence screening alone cannot identify recurring strains. Until now, strain typing has been costly and time-consuming, requiring an isolate in pure culture.

The Listeria PatternAlert™ assay is easy to use and provides results in just seven hours after a presumptive positive screen, without the need for an isolate. This fully automated method is easy to use and enables QA teams to take rapid action to reduce the risk of contamination and recall.

RAPIDLY IDENTIFY AND TARGET LISTERIA HARBORAGE SITES

Works directly from a positive enrichment

• Follows standard screening workflow
• Runs on fully automated Encompass Optimum™ workstation

Creates user-specific database of patterns

• No match to public database
• No speciation unless optional Lm-specific kit used

Provides rapid and actionable data to:

• Identify root cause of recurring contamination
• Eliminate harborage sites
• Quickly address emergent issues
