The aim of the study was to establish the protocol to evaluate the presence of Listeria spp. in food processing environments. The presence of Listeria spp. was evaluated in a selected restaurant in Serbia on three occasions. Samples were collected from 47 sampling spots in the commercial kitchen equipment and environment. The presence of Listeria spp. and Listeria monocytogenes were detected by conventional culture methods and by PCR method. The obtained results showed that the 23 swab samples were positive for Listeria spp. Interestingly, the swabs from the bread-cutting board and meat defrosting sink were positive for Listeria monocytogenes.
