摘要：Background: Today,bottled water is used in many countries of the world due to its relatively low cost,better taste,ease of access and low levels of impurities. In unfavorable conditions,the maintenance of microorganisms due to hydrophobicity and adherence to bottles and as a result of increased lipolytic activity can lead to undesirable changes in color,taste and odor,and in cases of more severe load,microbial contamination may cause unhealthy water and flooding. In this study,the presence or absence of coliform in a number of bottled water brands was examined. Methods: The microbial quality of 10 markers of bottled water present in the market of Sari that was randomly selected from each mark and three samples was examined. The samples were analyzed using the coliform - presence/absence (P-A) test. The results were compared with national standards and the World Health Organization (WHO) guidelines. Data were analyzed using SPSS version 24 and EXCEL. Results: Samples showed no microbial contamination Also,coliform and fecal coliforms were not observed in any of the samples. Finally,it was revealed that all cases were in accordance with national standards and WHO guidelines. Conclusion: Increasing the health indexes of places,food supply and distribution centers,and maintaining health conditions and measures that have been considered especially in the recent years on the health of bottled water,have greatly reduced the problems..
