  • Objectives: To describe the prevalence of E. coli and helminth eggs in vegetable in bun cha (grilled pork noodle) shops in Thanh Xuan and Cau Giay districts, Hanoi. Methods: Raw eaten vegetables from Bun Cha shops were collected and analysed for E. coli and helmith eggs in Hanoi. Results and conclusions: Studies showed that the prevalence of helminth eggs contamination in vegetables was 30% and E. coli 65% which is high for ready foods such as raw vegetables. No statistically significant difference in infection rates between the two different districts in the city was recorded. The main cause of microbial contamination of raw vegetables would be due to the practice of processing. Further studies on risk assessment need to be conducted to assess health risk caused by raw vegetable consumption in Bun cha to address appropriate measures to reduce health risk from this traditional food
