[Comparison of 3 enrichment media for the study of Listeria monocytogenes in foods].

Analysis organised by the BCR (Bureau Communautaire de Référence) using material in form of capsules containing a strain of Listeria monocytogenes of known concentrations in various types of foods were carried out within the interlaboratory trials. In this work, it is demonstrated that the LEB (Listeria enrichment broth) medium is, of the three media assayed, the most adequate to investigate this organism in foods.
