During investigations on street food vendors’ materials, seventy samples of three types of dish washing water (E1, E2, E3), eighty-five pieces of money, eighty utensils were collected for microbiological assessment. Hands microbiological status of one hundred twenty-five consumers and
seventy sellers were also assessed. The analysis revealed that 100% of E1 washing waters were very impure, while, 44.5% of second washing water (E2) were impure, 44.5% very impure and 11% acceptable. 45.45% of E3 washing water were acceptable, 27.27% impure and 27.27% very impure. The spoons and the dinner plates were sometimes contaminated with unacceptable levels (above 102) of different bacteria such as, coliforms and Staphylococcus aureus (P 0.05). Knives microbiological examination revealed presence of numerous bacteria (8.6 x 105 cfu/knife) such as coliforms, S. Aureus, Salmonella and Shigella. Pieces of money analysis revealed presence of coliforms and S. aureus. These data showing pathogen bacteria in food vending sites indicates hygiene monitoring failure.
