This product provides good condition for transferring of disease to human. This study was conducted to determine the frequency of <i>E.coli </i>and/or coliform contamination of Tabriz lighvan inMaraghe.<br> <b>Materials and METHODS:</b> in this descriptive cross sectional study, during six months, 100 samples of Tabriz lighvan cheese were in vestigated in Maraghe food and cosmetics laboratory.the samples were in vestigated for contamination with <i>E.coli </i>and Coliform according to Iranian standard guideline. The isolated bacteria were further identified by conventional bacteriologic tests.<br> <b>Results:</b> of the 100 samples, 98% were contaminated with coliform , 50% contaminated with <i> E.coli </i> , in 44% the intensity of pollution was very high, so the numbers of Pergenes in its Pelits were innumerable,also.66% of the samples have the PH higher than limit standard in Iran.<br> <b>Conclusion:</b> Result of this study showed that frequency of traditional cheese lighvan which were contaminated with <i>E.coli</i> and coliform was significantly higher than other surveys.
