10.22376/ijpbs.2019.10.1.p1-12 Volume 8 Issue 2 2017 (April - June) India is a country where each city boasts of its own unique street food and a large percentage of population relishes these delicacies. The most popular street foods in India are Panipuri or Gol gappas and Papdi chaat among others. The present study attempts to assess the bacteriology of khatta pani and masala sold with Gol Gappas in Dehradun district of Uttarakhand, India, in an attempt to throw light on the inherent risk associated with such foods. Panipuri samples were collected from different locations of Dehradun and analysed for the presence and count of pathogenic bacteria and their susceptibility to various antibiotics. Total Viable Count, Total Coliform Count and Total Staphylococcal Count were found to be in the range of 65 x 10 lessThan sup greaterThan 4 lessThan /sup greaterThan to 74 x 10 lessThan sup greaterThan 5 lessThan /sup greaterThan , 36 x 10 lessThan sup greaterThan 2 lessThan /sup greaterThan to 64 x 10 lessThan sup greaterThan 5 lessThan /sup greaterThan and 62 x 10 lessThan sup greaterThan 4 lessThan /sup greaterThan to 45 x 10 lessThan sup greaterThan 6 lessThan /sup greaterThan respectively. Six isolates were tentatively identified as lessThan i greaterThan Aeromonas sp., Klebsiella sp., Bacillus sp., Escherichia sp., Micrococcus sp. and Pseudomonas sp. lessThan /i greaterThan Antibiotic sensitivity test was performed against 8 antibiotics, in which lessThan i greaterThan Klebsiella sp. lessThan /i greaterThan was inhibited by all the antibiotics used. lessThan i greaterThan Aeromonas sp. lessThan /i greaterThan and lessThan i greaterThan Micrococcus sp. lessThan /i greaterThan showed resistance to Penicllin G and Vanomycin and were inhibited by the rest, while lessThan i greaterThan Bacillus sp. lessThan /i greaterThan , lessThan i greaterThan Escherichia sp. lessThan /i greaterThan and lessThan i greaterThan Pseudomonas sp. lessThan /i greaterThan showed resistance to Vanomycin. Based on this test, MRI% was calculated and was found to be in the range of 12.5 to 25% for all the isolates. Our study shows high level of contamination in one of the most popular Indian street food, lessThan i greaterThan Panipuri lessThan /i greaterThan . Therefore, regular monitoring is required for safety against these food-borne pathogens.
