FSIS personnel discovered the problem while reviewing historical sampling data in the context of recent intensified verification testing with multiple Listeria monocytogenes positives. The historical sampling showed a recurrence of Lm isolates with indistinguishable Pulsed-field Gel Electrophoresis (PFGE) patterns over a period of time within the establishment. Isolates present with indistinguishable PFGE patterns in environmental samples (including food contact and non-food contact surfaces) and on RTE meat products indicates that there are insufficient sanitary measures to prevent contamination of the production environment and the products with Lm.
