This study was aimed to compare sanitary conditions by detection of hygiene statue of thechicken breast meat taken from license and unlicensed slaughterhouses. Differentmicrobiological indicators were measured to determine some traits of the local fresh chickenbreast meat during different storage periods under refrigeration and freezing temperature. Alltests were made in the post-graduate laboratories of Animal Sciences Department, College ofAgricultural sciences, University of Sulaimani. The microbial content of breast meat in this studyshowed that the TPC was increased from 3.63×104 to 8.56×104 CFU/gm meat and from 4.13×103to 9.33×103 CFU/gm meat for both unlicensed and license slaughterhouses respectively, thatstored at fridge temperature. In freezing storage, total bacterial count was fluctuated in allsamples of breast meats during 90 days of storage. The coliform bacteria count in breast meat forunlicensed slaughterhouse were increased from 7.65×103 to 1.14×104 CFU/gm meat and weresignificant differences (P≤0.05) in all storage periods at refrigeration temperature were found. Atfreezing temperature, coliform have found only in 0 and 15 days of storage for both unlicensedand licensed. For psychrotrophic bacteria, the count have increased after 6 days of refrigeratedstorage for both unlicensed and licensed slaughterhouses samples and significant differenceswere obtained in most storage periods, whereas the count have fluctuated after 90 days offreezing storage. In generally, the results microbial indicators were within the standard limits ofpermission, Coliform bacteria count revealed that the number was higher than the acceptablecount (more than 103 CFU/gm meat) in case of unlicensed samples.
