The scope of the proposed research was to establish the presence of bacteria of the genus Salmonella spp. and Listeria spp. in the samples of poultry meat and eggs sold in the commercial food network of the Central Agricultural Market from m. Chisinau. The bacteriological investigations were performed in the laboratory of Microbiology of the Department II of the Faculty of Veterinary Medicine, SAUM. The serotyping of the isolated bacteria forms was performed at the Republican Center for Veterinary Diagnosis. The following culture media were used for isolation and identification: RVS broth, MKTTn broth, XLD agar, BSA, semi-Fraser broth, ALOA agar, Ottaviani and Agosti agar, Oxford agar. In total, 120 samples including 60 egg samples, 20 samples of frozen poultry carcasses and 40 samples from refrigerated broiler carcasses were collected and examined. As a result, the bacteriological investigation on the eggs of current consumption has established the presence of bacteria of the genus Salmonella typhimurium. Also, in the samples of frozen meat were isolated the serotypes Salmonella enteritidis and Listeria monocytogenes and finally, in the samples of refrigerated poultry carcasses was established the presence of serotypes Salmonella typhimurium and Listeria monocytogenes. The bacteriological investigations of poultry products (eggs and meat) showed the presence of their contamination with bacteria of the genus Listeria monocytogenes in 2.5% of the examined samples and with Salmonella bacteria in 8.3%, which may lead to the transmission of these bacteria to consumers by means of contaminated products.
