Abstract
The aim of this study was to assess the microbiological quality of street food samples. The food samples were bought from local vendors of Panvel region. Street foods are appealing due to its taste, low cost and easy availability. People get attracted towards variety of street foods like pani-puri, ice-cream, juices, sandwiches etc. to a great extent. These foods provide adequate nutrition and energy to the consumers and thus meet their daily requirement of energy and vitamins. The increase in number of cases of food poisoning may occur due to several factors such as poor local infrastructure and lack of sanitary surveillance. Hence, there is a need for proper microbiological survey of these street foods. The study aims at analysing the microbial quality of food samples like Pani- puri, sugarcane juice, ice-cream, kulfi, Sugar Candy, Pepsi stick and Alu Tikki. The samples were brought to the laboratory and tested for the presence of coliforms, Bacillus, Salmonella typhi, Staphylococcus aureus, fungi and yeast. Local Ice cream samples were found to be contaminated with coliforms, Staphylococcus aureus and Bacillus. Pani-puri water sample was found to be contaminated with Pseudomonas, Coliforms and Staphylococcus aureus. Pepsi Stick and Sugar Candy did not contain bacterial contamination but yeast and fungal growth was observed. Considering the socio-economic importance of street foods, it is required that the safety and hygiene of these foods is maintained properly.
