This study determined the microbial surface contamination of a total of 120 half beef carcasses from a high-capacity and a low-capacity beef slaughterhouse in Ankara. Samples were taken by aseptic excision-sampling of the muscle-adipose tissue surface of the flank, brisket and rump areas of each half carcass (0.1-0.2 cm thickness, 10×10 cm2 per site; 300 cm 2 total). The samples were analyzed for total aerobic plate counts (TAPC), coagulase-positive staphylococci (CPS), Enterobacteriaceae (EB), total coliform counts (TCC), Escherichia coli biotype I (EC) and presence of Salmonella spp. Levels of both microbial surface contamination and faecal contamination of the beef carcasses tested were high. Mean log TAPC, EB, TCC, EC and CPS were 4.78, 2.08, 2.03, 1.98 and 3.85 log cfu/cm2, respectively. EB, TCC, EC and CPS were detected in 81.6 % (98/120), 79.1 % (95/120), 65 % (78/120) and 38.3 % (46/120) of the samples, respectively. Salmonella spp. were not detected in any samples. It is therefore recommended that slaughterhouses introduce internal hygiene measures such as the HACCP system in order to produce beef of good quality and thus protect public health. © M. & H.
