Abstract: |
This study evaluated microbial contamination in selected street-vended beverages collected in Ea Kao Commune, Dak Lak Province, Vietnam. Total aerobic bacterial count, Coliforms, Escherichia coli, and Staphylococcus aureus were analyzed to assess food safety risks. The results showed that most samples exceeded the acceptable microbiological limits. Coliforms were detected in 100% of pennywort juice samples and 13.33% of peach tea samples, whereas no contamination was found in passion fruit juice. E. coli was detected only in several pennywort juice samples. S. aureus was identified in 60% of pennywort juice samples and 13.33% of peach tea and passion fruit juice samples, with counts ranging from 73.67 × 10³ to 179.67 × 10³ CFU/mL, exceeding regulatory standards. Among the tested beverages, non-heat-treated pennywort juice showed the highest microbial contamination level. The findings indicate inadequate hygiene conditions during beverage preparation, handling, and storage, posing potential health risks to consumers. This study provides scientific evidence for improving food safety management and hygiene control of street-vended beverages in the study area. |
