Abstract

Background: Street food has become increasingly popular due to its convenience and diversity, meeting the fast-paced demands of modern society. However, poor hygienic practices in food preparation at many vendors have increased the risk of foodborne illnesses. The presence of pathogenic bacteria and antimicrobial resistance in these foods represents a significant public health concern. Objective: To assess the level of bacterial contamination (aerobic bacteria, E.coli, Salmonella spp.) and to determine the antimicrobial resistance profiles of bacterial isolates from street foods sold around university and hospital areas in Bình Lợi Trung Ward, Ho Chi Minh City. Subject and methods: A total of 250 street food samples (boxed rice meals, banh mi with meat, fresh spring rolls, mixed rice paper, and crab noodle soup) were collected in Bình Lợi Trung Ward. A descriptive cross-sectional study design was employed. Results: The overall proportion of non-compliant samples was 72% (180/250). Fresh spring rolls showed the highest contamination rate (100%), followed by banh mi with meat (86%), mixed rice paper (68%), crab noodle soup (54%), and boxed rice meals (52%). The study isolated 43 E.coli strains (23.89%) and 9 Salmonella spp. strains (5%). Regarding antimicrobial resistance, E.coli exhibited the highest resistance to tetracycline (23.26%), followed by cefoxitin (16.28%), ciprofloxacin (13.95%), nalidixic acid and sulfamethoxazole/trimethoprim (11.63%). Notably, one contaminated sample C-7 demonstrated multidrug resistance to 6 out of 10 tested antibiotics. Meanwhile, Salmonella spp. showed high resistance to cefoxitin (66.67%), followed by tetracycline and nalidixic acid (33%). Conclusion: The study reveals high microbiological contamination in street foods in Binh Loi Trung Ward, Ho Chi Minh City, with antibiotic-resistant and multidrug-resistant E. coli and Salmonella spp., posing public health risks and emphasizing the need for strengthened food safety control.
