Eighty random samples of beef burger, kofta, hawawshi and variety meat (20 of each) were collected
from different street vendors in Cairo governorate to evaluate their value of Enterobacteriaceae. The
mean values of Enterobacteriaceae counts in the examined samples (cfu/g) were 2.67×10³ ± 0.53×10²
for beef burger, 6.41×10³ ± 1.72×10³ for kofta, 9.33×10³ ± 2.16×10³ for hawawshi and 1.09×10⁴ ±
0.25×10⁴ for variety meat, respectively. The results declared that the values of coliform count/g in the
examined samples of street vended meat products were 7.12×102 ± 1.46×102 for beef burger, 1.86×10³
± 0.59×103 for kofta, 4.27×10³ ± 0.92×10³ for hawawshi and 7.48×10³ ± 2.10×10³ for variety meat.
Accurately, O26: H11, O55: H7, O91: H21, O103: H2, O111: H2, O113: H4, O124, O126: H21 and
O127:H4 E. coli strains were isolated from such examined samples. Concerning salmonella organisms,
S. entertidis was isolated from beef burger (5%), hawawshi (5%), variety meat (10%) while not isolated
from kofta, S. Heidlberg was isolated from kofta (5%), S. Infantis was isolated from hawawshi (5%), S.
Montevideo and S. Typhimurium were isolated from variety meat (5%) for each.
