Abstract

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.
