This study was conducted to derive the level of importance of HACCP evaluation items in meat packing plants. Based on the results, we proposed a method to increase the objectivity of HACCP criteria for meat packaging plants by giving different evaluation scores to each evaluation item. To assign a differential score for each HACCP evaluation item, the severity of the hazard and the rate of non-compliance in the past 3 years (3,905 of the prerequisite section, 2,057 of the HACCP management section) were analyzed. The results were as follows. The importance and score differentiation of each HACCP evaluation item was derived. The total scores of the prerequisite section and HACCP management section were set at 200 and 100, respectively. However, to maintain objectivity of the HACCP evaluation items, further study is needed to develop detailed criteria for each HACCP evaluation item and score.
