FoodChek™ Actero™ Listeria Enrichment Media, followed by rapid real-time processing with the DuPont™ BAX® System, was approved by AOAC-RI to allow a singlestage, 20-26 hour enrichment (sample-dependent). This method can return Listeria results in just 22 hours for some matrices, one of the fastest time-to-results available for the pathogen in the food safety industry today.
