Abstract :

The important of transmission of pathogens through ice is not less than transmission it through the water. The cause's ice contamination is contaminated water, unhealthy ways of transit, distribution and inappropriate keeping conditions. In this cross-sectional study, a total sample of 36 from four factories, ice storage of Urmia City is selected randomly from 3 parts of feed water, production process and ice output in the summer. The samples are investigated from the view of total coli form and fecal coli form. The health condition of factories and the method of chlorination of water resources are assessed by check list. The results showed that, 50 percent of the samples of raw feed water to ice maker factories and the product process more than standard and 16.67% from them contaminated with fecal coli form. And in ice output 58.33% and 8.33%. The survey about health condition of factories showed that, 75% factories in order to buildings position and personal health, 56.2% with tools and 25% by chlorination in were appropriate situation, but the method preservation and storage of all factories were inappropriate from the view of health. The survey results showed that, lack of water chlorination to ice maker factories is the main factor of bacterial contamination of ice production. Therefore, authorities should pay more attention on microbiological health conditions of ice including microbiological investigation and supervision on production process distribution and transit.
