Abstract

A cross-sectional study was conducted to determine microbial quality of domestic brands of bottled water due to the increased demand and consumption of bottled water in Malaysia. This study aims to determine microbial quality of domestic brands bottled water commercially available from outlets. Questionnaire was distributed among 215 students of Faculty of Medicine and Health Sciences in order to determine the level of knowledge and attitude of respondents towards microbial quality in bottled water. Microbiological quality of 11 different bottled water products were tested for total coliform, Escherichia coli and Pseudomonas aeruginosa. The membrane filter technique was applied with culture grown on M¬coliblue24 Broth and Pseudomonas Broth for total coliform and Escherichia Coli as well as Pseudomonas aeruginosa, respectively. Most of the respondents have poor knowledge of microbial quality in bottled water (123 (57.2%)) while 92 (42.8%) of respondents have good levels of knowledge regarding microbial quality in bottled water. Attitude level showed that most of the respondents have poor attitude towards microbial quality in bottled water which was 151 (70.2%) while 64 (29.8%) of respondents had good level of attitude regarding microbial quality in bottled water All samples showed negative growth of Escherichia Coli and Pseudomonas aeruginosa. Except for total coliform which have been detected in two samples. Detection of total coliforms showed that mineral water source is being contaminated with surface water or waters draining from surface soil. The number was compared with the WHO Guideline for Drinking Water Quality (2011) and National Standard for Drinking Water Quality (2000) and all the bottled water brands were fit for human consumption as drinking water. Routine monitoring and applying local and international criteria for bottled water are crucial to maintain its quality as well as to protect the human health. Keywords: Bottled water, total coliform, Escherichia Coli, Pseudomonas aeruginosa
