Bacterial contamination of surface carcasses in relation to the order of the slaughtered swine.

摘要

The aim of the study was evaluating the bacterial contamination of surface carcasses in relation to the order of slaughtering on the day of slaughter. The total bacteria count as well as the enterobacteriaceae, enterococci and Salmonella rods were described. The total count of aerobic bacteria in the swine carcasses vacillated from 4.3x103 to 8.7x103 microorganisms per 1 cm2. Significant differences in the level of contamination of the examined carcasses were not discovered. Enterobacteriaceae were confirmed in 8 samples (27%) and enterococci in 9 (30%). Salmonella rods were not determined in the examined samples. The order of slaughter of the swine did not influence the general level of bacterial contamination of the carcasses. The level of the sanitary inspection at the examined slaughter house was at a good level.
