Ten samples of a popular street food "dahi bhalley" and 5 dishwater, used repeatedly for washing the plates, were collected from different areas of Lahore. They were processed on different media for the detection of coliform and certain pathogenic bacteria. All the food samples showed growth on Streptococcus selective agar, 80% on MacConkey agar and mannitol salt agar media, while 70% indicated the presence of coliform as assessed by growth on brilliant green bile broth and EMB agar. In case of dishwater all the samples showed growth on the five media used. These results indicate that the street- food is unsafe for human consumption as it may lead to food poisoning and enteric infections by the pathogens it harbours.
