A study, conducted during 2013-2014, aimed at monitoring the number of microorganisms isolated from bovine, sheep and pig carcasses and grown on nutritive media: peptone agar, Endo, bismuth sulfite agar and Saburo. The samples were taken from the surface, as well as from the depth of carcasses (from livestock farms from different districts of the Republic of Moldova), during their marketing period. Microbial dominant species from carcass surface were represented by E. coli and Streptococcus. The greatest number of microorganism colonies were found on the samples from sheep and pig carcasses, the contamination level being higher in the months of April and July. The number of colonies taken from the surface of carcasses, compared with those taken from deep muscle, was 2-3 times higher with a higher incidence on peptone agar and Endo media: up to 66 colonies (sheep), 38 colonies (pig) and 31 colonies (cattle). The number of colonies identified on bismuth sulfite agar and Saburo media was more reduced.
