Abstract

Using of packed WATER in 20 liter-recycle containers and also disposable one-liter bags is very common in AHVAZ. These packages have lower price compared to disposable bottles of mineral WATER. In this study, 180 samples of packed WATER from three different companies (30 samples from each company in each season) were examined during cold and warm seasons (totally 90 samples in each season). After preparing samples, total microbial count with pour plate method, probable contamination to COLIFORM with MPN method and tests for confirmation of E. COLI and also TOTAL HARDNESS evaluation of samples were performed. According to the results, the mean of total microbial counts of supplied WATERs from companies (1), (2) and (3) were 90.8±26.3, 46.92±9.41 and 8781±1082 CFU/ml respectively, In comparing the results with standard limits, only company number 3 had a significant difference with standard limit (5x102 CFU/ml). The means of Coli forms number in WATER samples of the companies (1), (2) and (3) were 0.993±0.342, 1.705±0.392 and 3.437±0.697 CFU/ml respectively, and according to these results, all the companies had significant differences with standard limits of packed WATERs (0 CFU per 100 ml). There were 2 (3.3%) E. COLI positive in WATER samples of each company. Also the WATER samples, from all companies had TOTAL HARDNESS in the limit of standard levels. Conclusively, the percentage of suitable WATER samples (with respect to TOTAL COUNT, COLIFORM, E. COLI and TOTAL HARDNESS) of companies (1), (2) and (3) were 80%, 70% and 25% respectively. Company (3) (one-liter bags) had a significant difference with two other companies in this respect. Also there was statistically significant difference between cold and warm seasons in WATER samples of all companies from the aspect of hygienic quality (hardness and microbial factors). Regarding the results of this survey, it is necessary for authorities to pay more attention to the companies producing packed WATERs.
