ABSTRACT
The studies on the presence of Listeria spp. microorganisms in beef, pork and raw sausages were carried out. Food samples were purchased from local retailers. In total, 160 samples were examined, 32 from each kind. Listeria strains were isolated from pork (87.5 %) and beef (68.7%). The sausage samples were contaminated in 46.8% to 62.5%. Listeria monocytogenes was the most often isolated species in pork and beef. L.innocua was usually found in sausages. Longer time of preincubation was required to isolate listeria from sausages. Majority of isolated strains of L.monocytogenes were of serotype 1.
