Abstract

Research to measure the fly density and environmental factors in street vendors foods was done along the Margonda Avenue, Depok City, West Java Province, Indonesia used crossectional design. A total of 100 street vendors were selected randomly, from which different types of foods were sampled for fly density and Escherichia coli. Fly grill was used to measure the fly density, otherwise the analysis of E. coli using the Most Probable Number (MPN) method. Also, environmental factors of street vendors and personal hygiene of food hanlers were observed. Analizing of the data used Chi Square Test and Logistic Regression. It was found that the fly density was a quite high (more than 6) with the average in each location were 9.38 in Point-1, 8,53 in Point-2, and 10.33 in Point-3. Forty one (41) percent of samples contaminated by E. coli and 14% contaminated by Salmonella. The average flies’ density around the street vendors area were high. Almost half of the food sold by street vendors was contaminated by E. coli, some contained other pathogens such as Salmonella. Based on the statistical test, there was an association between flies density and E. coli contamination on food. But statistically, high flies density will prevent contamination as much as 3.86 times (OR=0.26).
