    Fecal coliform contamination of beef carcasses during the slaughtering process
    (FOOD NUTRITION PRESS INC, 2001) Yalcin, S; Nizamlioglu, M; Gurbuz, U
    The purpose of this study was to determine the fecal coliform counts of beef carcasses during different stages in the slaughter process. A total of nine carcasses were selected at random in the abattoir. The samples were taken by excision from three different sites; rump, brisket and shoulder. The samples were collected from the same carcasses at four different stages of processing; after dressing, after evisceration, after washing and after chilling for 24 h in a chilling room. The processing steps did not increase the fecal coliform counts on the rump samples. There were no significant differences in the samples of rump and shoulder among different processing steps. The contamination level of the brisket after washing was significantly higher than other processing steps. Brisket and shoulder parts are critical points for microbiological sampling as these sites showed higher microbial counts after chilling steps. The data obtained have relevance for the planning of washing methods for the production of clean and safe carcasses.

    Microbiological conditions of sheep carcasses during the slaughtering process
    (FOOD NUTRITION PRESS INC, 2004) Yalcin, S; Nizamlioglu, M; Gurbuz, U
    This study was undertaken to determine the microbiological quality of sheep carcasses during different stages in the slaughtering process. A total of eleven carcasses were selected at random in an abattoir. The samples were taken by excision from four different sites; leg, brisket, shoulder and neck. The samples were collected from the same carcasses at four different stages in the slaughtering process; after dressing, after evisceration, after washing and chilling. The aerobic mesophilic bacteria, coliforms and Enterobacteriaceae recovered from each sample were enumerated. Chilling reduced the aerobic mesophilic and coliform counts of carcasses, significantly. Levels of carcass microbial load after chilling were 1.69, 0.11 and 0.11 log cfu/cm(2) for aerobic mesophilic counts, coliform counts and Enterobacteriaceae counts, respectively. According to data obtained in the present study, chilling of carcasses was the most important step in improving the hygienic quality of carcasses. Processing stages changed significantly both aerobic mesophilic and coliform counts of neck, therefore, among different sites of carcass, neck should be the only critical site for microbiological sampling for sheep carcasses.

    The possibility of using potassium sorbate in cemen and its effect on the microbial quality of pastrami
    (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1999) Tekinsen, OC; Dogruer, Y; Nizamlioglu, M; Gurbuz, U
    This investigation was carried out to determine the possibility of the use of sorbic acid in cemen and its effect on the microbial quality of pastrami. The pastrami samples were experimentally produced by the tradional meted. The garlic ratio of cemen paste which consist of 50 % water, 15 % cemen flour, 20 % garlic and 15 % red pepper was decreased 25 %, 50 % and 75 %. The cemen samples were respectively suplemented with 0, 0.15 % and 0.30 % potassium sorbat. Microbial quality (general viable microorganisms, mould, yeast, Lactobacillus, Staphylococcus-Micrococcus and Enterobacteriaceae) of the samples were determined on the 1st, 7th, 15th, 30th and 60th days storage periods. It was observed that the number of general viable microorganisms, mould, yeast, Lactobacillus, Staphylococcus-Micrococcus and Enterobacteriaceae of the samples on the Ist, 7th, 15th, 30th and 60th storage days generally increased depending upon the decreasing amount of garlic in cemen; however, the potassium sorbate added to cemen paste at the 0.30 % level significantly prevented the increase of microorganisms. The microbial stability of pastrami samples manufactured with containing 25 % garlic and 0.30 % potassium sorbate were superior than that of other groups. In conclusion, the pastramies made with cemen suplemented with 15 % garlic and 0.30 % potassium sorbate were of good quality from microbiological point wiew.
