Validity Study: Total of twenty five samples were taken, five samples from each of the five different Sunday bazaars of Karachi. All the samples were evaluated from the MPN technique for microbial analysis. Results: The MPN technique gives the consistent results of the presence of microbes in all the selected samples collected from the particular Sunday bazaars of Karachi. Analysis showed that all the dishes selected were positive for the presence of the microorganism rendering cent percent result showing the contamination of the selected cooked food dishes with the microorganisms.
