In Dhaka, the capital of Bangladesh and one of the most densely populated cities of the world, different categories of street foods are widely consumed by all classes of people, especially for iftar during the holy month of Ramadan. The objective of this research was to assess the microbiological quality of street iftar food items collected from a street in Chalk Bazar locality of Dhaka along with the antibiogram profile of the bacterial isolates. A total of 74 samples belong to ten different categories of street food items and 8 different types of street vended juices were collected aseptically. The bacteria were isolated by using different culture media. The antibiotic susceptibility of the bacterial isolates was determined by the disc diffusion method. In case of street food total viable bacteria (on average of 6 log10 CFU/g). On the other hand, an extended number of total viable bacteria were encountered in all juices samples which also on an average of 6 log10 CFU/mL. Fungi, Pseudomonas spp. and Staphylococcus spp. were found in the majority of the samples irrespective of the categories. Few samples were contaminated with Escherichia coli and Klebsiella spp. Most of the cultivated bacterial strains exhibited resistance against commonly used antibiotics, while several isolates were noted to be multi-drug resistant. The present study revealed a huge array of microbial load which indicates a high risk to public health. Presence of antibiotic-resistant bacteria heightened the risk by many folds and urges the need for frequent surveillance.
