The objective of this study was to investigate the food safety status of street foods in the city of Can Tho, Vietnam. A total of 410 consumers was interviewed to get an insight into the popular street foods in the studied area. Vietnamese sandwich (34.63%) and sugarcane juice (24.51%) were consumed popularly according to the survey. A total of 263 street food samples (i.e.Vietnamese sandwich, n = 131 and sugarcane juice, n = 132) were collected from different locations such as schools, hospitals, markets, and other locations in four districts (i.e. Ninh Kieu, Cai Rang, Phong Dien and O Mon) of Can Tho city for microbiological analysis. Total aerobic mesophilic counts (TMC), yeast and mold, coliform, E. coli, and Staphylococcus aureus were assessed. Microbial contamination of Vietnamese sandwich was 5.7-9.2 log CFU/g (TMC), 2.0-7.4 log CFU/g (yeast and mold), 2.5-7.9 log CFU/g (coliform), 1.0-5.9 log CFU/g (E. coli), and 1.7-6.6 log CFU/g (Staphylococcus aureus). There was a significant difference in Vietnamese sandwich sampling among districts (p0.05) was observed in sugarcane juice samples among districts and locations. The observation of the handling practices of street food vendors showed inadequate hygiene practices, assessment of the street foods safety showed that they do not satisfy the Vietnam hygiene standard of specific foods. These findings give an insight into the safety status of sampled street foods and may provide needed information for Vietnam’s authorities to further improve the safety of street food and create food safety awareness among consumers and handlers, thereby preventing risk to public health.
