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.
