Escherichia coli is a normal inhabitant of the intestines of
animals and humans but its recovery from food may be of
public health concern due to the possible presence of enteropathogenic and/or toxigenic strains which lead to sever
gastrointestinal disturbance. It is
considered as the major indicator of fecal pollution in food
production. Its presence in processed foods results from
recontamination, because this bacterium usually does not
survive food preservation processes. The main reasons for the
presence of E. coli in food products are nonobservance of
relevant technological regimes, incompliance with recommended
process standards, and the lack of personal hygiene
