  • Title: The challenge of enumerating Listeria monocytogenes in food.
    Author: Auvolat A, Besse NG.
    Journal: Food Microbiol; 2016 Feb; 53(Pt B):135-49. PubMed ID: 26678141.
    Abstract:
    Listeria monocytogenes is recognised as a serious foodborne pathogen in humans. However, food products are usually contaminated at low levels (i.e. <100 CFU/g) and there is still no adequate enumeration method for testing food. Much research has been carried out to improve Listeria enumeration methods, leading to several proposed alternative methods such as the most probable number technique, molecular-based methods and bacterial cell concentration techniques. Here, we catalogue the current knowledge concerning L. monocytogenes enumeration, with a particular focus on the problem of enumerating low level contamination.
