Title
bacteriological evaluation of bottled water from domestic brands in tehran markets, iran
English Abstract
Transmission of waterborne disease is a major concern of public health and it is important to know microbial quality of bottled water. This study was conducted about bacteriological evaluation of bottled water from domestic brands in Tehran markets. 35 samples of bottled water were collected randomly from seven different brands. The samples were examined about HPC bacteria, coli forms and E. coli according to standard methods for examination of water. Results showed that the mean and standard deviation of HPC bacteria in examined samples were 3.14×102 and 2.07×102 CFU/ml, respectively. HPC was ranged from 2.4×101 to 9.50×102 CFU/ml among bottled water examined. Total coliforms bacteria were detected in 14.28% bottles of mineral water. None of the bottle samples was positive for fecal coliforms and Escherichia coli. The presence of coliforms in bottled water suggests the potential of pathogenic enteric microorganisms and it requires an improved surveillance system in production of bottled water.
