This study was conducted to propose the use of a non-compliance rate for evaluation of the HACCP operational condition. We calculated the sectoral non-compliance rate from the HACCP prerequisite evaluation reports. This rate indicates vulnerability of the operational prerequisite conditions that must be improved to increase HACCP reliability for safe foods. The common weak point in the livestock products industry was storage and transportation management, and operating condition in butcher shops were worse than those for the other livestock businesses. In order to obtain better information on findings, evaluation items should be improved simply with one item for evaluation of one check point.
