Enumeration and Identification of Listeria monocytogenes on Ready-to-Eat (RTE) Frankfurters

Abstract

We will practice enumerating Listeria monocytogenes on commercial frankfurters by inoculating, dilution technique, and spread plating onto selective medium Modified Oxford Agar. The presumptive colonies will be identified using Gram staining, catalase test, and 12L test. In this chap- ter, it requires students to finish part of the work independently.
