The assessment of the bacteriological quality among 390 samples of bottled drinking water was studied. The samples were tested for Escherichia coli, Clostridia, total Coliform, Streptococci feacal and Pseudomonas aeruginosa. The rates of microbial contamination in bottled drinking water were of 56.7% (2017) and 50.7% (2018). The samples failed to meet QCVN drinking water standard of acceptable limits of bacterial presence including Pseudomonas aeruginosa (41.5%), total Coliform (11.8%), Clostridia (4.6%); Escherichia coli (4.9%) and Streptococcifeacal (1.3%). It is necessary to strengthen the inspection, supervision, propagation, and education that give warnings, ensure water quality and raise the awareness of producers, traders and consumers.
