摘要：The bacteriological quality of microfiltered drinking water dispensers was evaluated, through enumeration of heterotrophic plate count at 22 and 37 °C, total coliforms, Escherichia coli, Enterococcus spp. and Pseudomonas aeruginosa. The aim of this research was to control the hygiene of the microfiltered water and to evaluate the effectiveness of the microfiltration procedure on the survival of bacteria. In total, 54 water samples were analyzed. The results indicated a high contamination frequency with P. aeruginosa (25 and 20% in room temperature and chilled water samples, respectively) and therefore the need to improve the efficacy and the frequency of the dispenser sanitation procedures.
