Examination of Listeria monocytogenes in milk products.
The aim of our examinations was to make clear whether listeriae occur in Hungarian milk products, first of all, in cheese. In the course of model-examinations, the most suitable enrichment- and isolation media were selected. An examination method was elaborated involving cold-enrichment and KOH treatment. Milk samples from different parts of the country and cheeses produced by different technologies were examined. To the present, 80 raw milk samples and 100 cheese samples were examined. Listeria monocytogenes could be detected in 3 raw milk and 2 cheese samples.
