Methods; In this descriptive ,cross-sectional study samples were collected from seven ice factories in Bandar Abbas. Sampling was done by standard method.    Amount of the Contamination of ice and water to coliforms was investigated by the Multiple Tube method to determine the MPN, isolate bacteria and identify the microorganisms using conventional bacteriological techniques and counting the total count of bacteria by the Plate Count method on a nutrient agar medium. The data was analyzed by the SPSS software. Results; In this study, a total of 84 samples were investigated. Gram-positive bacteria (65.5%) and gram-negative bacteria(34.5%) were separated from each other. The MPN rate in samples and total count of bacteria were 0->1100 and 2×101×104 CFU/mL, respectively. Conclusion;The results suggest that necessary precautions be taken by environmental health specialists and other public health authorities in production, transportation and distribution of the ice blocks to reduce the rate of bacterial contamination.
