Raw milk samples obtained from the Foundation of Milk Industry, three private dairy companies and individual dairy farms in Sivas, were tested for the presence of Listeria species. A total of 100 raw milk samples were analysed by Food and Drug Administration (FDA) and two-stage enrichment techniques. Two-stage enrichment procedure was found to be more effective than FDA method in isolating Listeria species from raw milk. The overall incidence of Listeria species in raw milk was 6%. Listeria monocytogenes was found in 4% of the raw milk samples, while L. innocua was found in 2% of the samples. One sample was revealed to contain two serotypes of L. monocytogenes.
