Abstract
Atotal of three hundred swabs were taken from 75 buffalo carcasses slaughtered at Cairo abattoir. The swabs were taken from four areas
represented by abdomen, round, shoulder and brisket (each of 50 cm2) swab samples were examined bacteriologically for aerobic plate count,
Enterobacteriaceae count, colifonn count, Staphylococcus aureus count and isolation of Salmonellae.
The mean aerobic plate count of abdomen, round, shoulder and brisket were 8x10’, 6.3x105, 9.4x105 and 1.5x105, respectively.
While the mean Enterobacteriaceae count were 2.7x104, 9.4x103,
-
1.6x104 and 1.5x104 in examined samples of abdomen, round, shoulder and brisket, respectively.
Concerning the mean Staphylococcus aureus count was 7.5x102, 4.5x102, 6.2x102 and 1.5x102, respectively. While coliform MPN/cm2 were 1.3x102, 0.4x102, 1.7x102 and 2.9x102 for abdomen, round, shoulder and brisket, respectively. Salmonellae were found in 6.7%, 1.3%, 18.7%, 2.7% and 7.3%, while Escherichia coli was found in 16%, 8%, 20% and 8% for abdomen, round, shoulder and brisket, respectively. Totally Salmonellae were found in 7.3% and E. coli was found in 13% of total swab samples.
Serological isolates of Salmonellae were S. typhimurium in 4.33%, S. anatum in 2%, S. agona in 0.66% and S. montivedeo in 0.3% of total swab samples while, E. coil serotypes isolates were 055:K59 in 4%, 0111:K58 in 3.33%, 026:K66 in 2.33%, 0119:K69 in 2% and 044:K74 in 1.33%.
The public health importance of isolated organisms as well as the suggested measures for improving the quality of buffalo carcasses were
discussed.
