Abstract

The purpose of the study to determine the bacteriological quality of the bottled water consumed by students and workers of Bioanalysis and Department of Mental Health, and the water placed in the dispensers, is to compare the bacterial quality before and after the water is placed in the dispenser. To this end, mesophilic aerobes were determined by the plate pouring technique, total coliforms, heat-resistant coliforms, Escherichia coli and Pseudomonas aeruginosa by the membrane filtration. We randomly selected 11 sealed bottles and 11 samples from the dispensers. The mesophiles aerobic load in all the samples of drinking water showed a higher growth than that established by the Official Gazette (GO) of the Bolivarian Republic of Venezuela No. 36,395; for total and heat-resistant coliforms 27% and 36% respectively of the samples do not meet the criteria established in the Venezuelan standard COVENIN Nº 1431-82 and in the GO Nº 36,395; It also occurs with the results obtained for Pseudomonas aeruginosa, where it is observed that 91% of the samples do not meet these requirements. In none of the analyzed samples was the presence of Escherichia coli observed. The water samples from the dispenser showed a significant increase in microorganisms compared to water in the sealed bottles, which allows us to conclude that the dispensers represent a source of contamination for bottled water.
