The isolated Salmonella serotypes were 4 strains of Salmonella typhimurium and 3 strains of Salmonella enteritis's which were detected in the examined beef burger samples, while 3 Salmonella paratyphoid- B and 2 Salmonella Newport strains were recovered from luncheon samples.

Regarding E.coli, they were detected in only 8 (13.3 %) samples; 5(16.7 %) strains from beefburger and 3(10 %) from luncheon.

The isolated E.coli strains from beef burger were identified serologically into 5 strains E.coli Om K58, while the strains isolated from luncheon were two strains E.coli Oi28&67 and only one strain E.coli O126 K7.
