M.A.Hassan1, G.I.Heikal2 and R.M.Barhoma3"


A total of 60 random samples of cattle carcasses were collected from the different abattoirs located in Qaliubiya governorate. The samples taken from each carcass were represented meat, spleen, liver and kidneys (15 samples of each), the samples were collected directly after slaughtering and evisceration. The collected samples were subjected to bacteriological examination. The results of microbiological examination in examined samples of meat, spleen, liver and kidneys revealed that the mean of total APC were 2.26×104± 0.51×104, 4.09×104± 0.63×104, 1.95×105± 0.27×105, 6.48×105± 1.89×105, respectively. While the mean of coliform count with the mean of 5.54×102± 1.02×102, 8.92×102± 2.14×102, 9.17×103± 2.35×103, 2.38×104± 0.61×104, respectively, total Staphylococci count with the mean of 1.28×103± 0.33×103, 2.69×103± 0.47×103, 4.49×103± 1.-06×103, 1.10×104± 0.25×104 respectively. The incidence of Staphylococcus aureus was 6.67%, 13.33%, 13.33%, 26.67% in meat, spleen, liver and kidneys, respectively. The public health importance of isolated bacteria and the possible sources of contamination of cattle carcasses with such bacteria as well as suggestive hygienic measures to improve the quality of carcasses were discussed.
