Abstract

The cross-sectional descriptive study was conducted at 65 bottled drink water product production facilities in Dak Lak province in 2023. The objectives were to determine the prevalence of bacterial contamination in bottled drinking water products at some production facilities in Dak Lak province and analyze related factors. The results indicated that 42/65 (64,0%) of samples did not meet the bacterial requirements according to QCVN 6-1:2010/BYT. Unsatisfactory bacterial criteria included Coliform (50.5%), P. aeruginosa (50.5%), and Clostridia (4.6%). All samples were not detected for E. coli and Streptococci feacal. The main factors influencing bacterial contamination of bottled drinking water were the layout design of the production area; factory structure, means of washing and disinfecting hands, sanitary conditions of the jar, practice of personal hygiene, practice cleaning the jar, and practice of packaging the products.
