The microbiological quality of bottled water from different sources in the United Arab Emirates was studied. The study was done on 80 commercial bottled water samples from 4 different manufacturing companies. The results showed that 75% of the 20-L bottles were contaminated by 10 different species of bacteria, whereas 10 to 40% of the 1.5-L bottles were contaminated by 2–4 types of micro-organisms. Heterotrophic bacteria and a few types of human-associated bacteria were isolated. The most frequent organism found in all types of water was Acinetobacter Iwoffii with several genospecies. Storage of water at 4°C preserved the water without microbial multiplication, whereas at 25–37°C, most microbes multiplied, and at 42°C, most contaminants were destroyed. The source of these micro-organisms and their untoward effects on the drinking water were not determined. |
