Abstract
This study was planned to throw the light on the prevalence of E. coli in
meat and some meat products and to determine its virulence gene that may be
considered a significant food safety threat.
Two hundred samples of meat and some meat products; minced meat,
kofta, sausage, beefburger, pastirma, luncheon and hot dog (25 of each) were
randomly collected from supermarkets, butcher shops and street vendors in

coli was (17%) from the total collected samples at a percentages of (44%, 28%,
20%, 16%, 12%, 8%, 4% and 4%) respectively.
Serological identification of E. coli isolated from meat, minced meat,
beefburger and pastirma revealed that strains of E. coli were belong to
serotypes O:157 K:-, O:91 K:-, O:103 K:-, O:125 K:70 respectively, while
O:26 K:60 serotype was isolated from kofta and sausage. Strains from luncheon
and hot dog were Untyped, in addition to isolated E. coli strains from all
samples were untyped by using Anti-coli I, II and III.
