A total of 100 random samples of ready- to – eat sandwiches of beef products of kofta , liver, shawerma, and sausage
products (25 samples of each ) were collected from different fast food services in different districts at Kaliobia governorate
to be examined bacteriologically for detection of Coliform and Staphylococcus aureus microorganisms. The obtained
results in the present study indicated that the mean value of coliform counts (cfu/g) in the examined samples of ready- to
- eat meat products were 2.5 x 10³ ± 0.74×10³ for beef kofta, 8.85x10² ±1.92x 10² for beef shawerma, 8 x10³ ± 1.65 x 10³
for beef sausage, 9.0 x 10⁴ ± 2.30 x 10⁴ for beef liver, furthermore the coliform were detected in 60% of beef kofta, 40%
of beef shawerma, 52% of beef sausage and 80% of beef liver. The obtained results in the present study indicated that the
staphylococcus aureus was detected in 32% of beef kofta, 44% of beef liver, 8% of beef shawerma and 16% of beaf
sausage .The obtained results in the present study indicated that the ready- to-eat liver sandwiches were more
contaminated with Staphylococcus aureus as compared with those of kofta, shawerma and sausage. The examined
samples of ready-to-eat liver sandwiches showed high incidence of coliform than those obtained by kofta, sausage and
shawerma.
