A total of 104 dairy product samples (33 kareish cheese, 38 yoghurt and 33 sour cream) were randomly purchased from different shops, markets and street vendors in Kafer El-Sheikh city for isolation and serological identification of E.coli serotype O157:H7.

24.2%, 21% and 42.2% of kariesh cheese, yoghurt and sour cream respectively, contained E.coli.

All the suspected strains were serologically identified for E.coli O157:H7, using E.coli O157:H7 kits.

The organism could be detected in 3% of examined kareish cheese while could not be detected in yoghurt and sour cream examined samples.

E.coli serotypes of O157:H7, O111:H4,, O26:H11, O114:H21,O86, O55:H7,, O125:H21,O126, O128:H2, and O124 were serologically identified by percentages of (12.5%, 0 and 0), (25%, 25% and 26.6%), (12.5%, 12.5 % and 13.3%), (12.5%,12.5% and 6.7%), (0 ,12.5 % and 0) , (0, 12.5 %and 6.7%) ,(0,0 and 20%), (12.5% ,0and 0), (12.5% , 25% and 20%) and (12.5%,0 and 6.7%) of the isolates of each examined kareish cheese, yoghurt and sour cream samples respectively.
