The purpose of research was to study contamination of meat and meat products of poultry farming with Salmonella and Proteus spp. Investigation was carried out in Perm during the period from January to July 2015. The strains of Proteus vulgaris, P. mirabilis, P. morganii, P. rettgeri, S. enteritidis, S. infantis allocated from chicken meat and chicken semi-finished products (98 samples in total) were material for research. Research was conducted according to the technique approved by the state standards. Following solid nutrient media were used in the work: Endo's agar and bismuth-sulfite agar. As a result, it was established that the studied chicken meat and semi-finished products in 39.80% of cases showed growth of Proteus spp. on solid nutrient media. Thus, mechanically deboned chicken is more often contaminated with Proteus spp. than other meat products of poultry farming (43.24% of total number of positive results). Salmonella spp. was found in 1.87%. The bismuth-sulfite agar is the most effective nutrient medium for Salmonella spp. detection in foodstuff and is capable to minimize the crowding properties of Proteus spp. This medium allows indicating Salmonella spp. the colonies of which give characteristic metal gloss. The meat from forcedly killed and ill birds should be subjected to the bacteriological research in order to avoid the infection spreading.
