Abstract
Recent years have witnessed a considerable development in poultry, industry generally and particularly in commercial processing of eviscerated and ready-to-cook poultry in order to meet the increasing demand So, this work was planned to assess the public health importance of pathogemc organisms in slaughtering process and equipment
A total of one hundred samples of chicken carcasses were taken from I private shops at Alexandria governorate as 50 swabs from the skin and 50 samples from chicken meat and all examined organoleptically, chemically and microbiologically
Results revealed no organoleptic or chemical changes in the examined
samples.
Microbiological results revealed that the total aerobic count was ranged
from 1.0 x io to 1.9 x 1081g with a mean value of4.9 x io ± 1.5 x 107/g in
the examined chicken meat samples, but in skin it ranged from 5.5 x iO to 1.7
x 108/cm2 with a mean value of 7.5 x 10 ± 9.4 x 106/cm2.
While the total Enterobacteriaceae count of examined chicken meat samples was ranged from 5.0 x 102 to 9.0 x 1051g with a mean value of 3.6 x
io ± 9.0 x 103/g but in the examined skin swabs it ranged from 1.0 x 10 to 3.0 x 106/cm2 with a mean value of 9.2 x io ± 1.5 x 1041cm2.
The total Coliforms count in examined chicken meat samples was ranged from 1.0 x 102 to 3.0 x 105/g with a mean value of 3.9 x io ± 2.1 x 103/g, but in examined chicken skin samples it ranged from 1,0 x 102 to 3.0 x 105/cm2 with a mean value of 8.6 x io ± 1.6 x 10’/cm2.
Results also reveal that Staphylococcus aureus count of chicken meat
samples was ranged from 2.0 x 102 to 3.0 x 105/g with a mean value of 5.2 x
l0 ± 8.9 x 103/g but in examined chicken skin samples it was ranged from 2.0
x 102 to 1.4 x 105/cm2 with a mean value of 2.4 x 10 ± 3.9 x 103/cm2.
Furthermore, identification of Coliforms revealed that the isolated organisms were E. coli, Enterobacter cloacae, Enterobacter aero genes, Enterobacter agglomerans, Enterobacter intermediu,n, Citrobacter freundii, Citrobacter diversus, Citrobacter agglomerans, Klebsiella pneumoniae, Kiebsiella oxytoca and Kiebsiella mobilis from all examined samples of chicken meat and skin with percentages ranged between 34.49% and 3.45 % in meat samples of chicken and percentages ranged between 31.82% and 5.54% in skin samples.
