Theresults showed that COI estimates ranged between 217∼378 billion Won while WTPestimates ranged 14,160∼28,320 billion Won. Huge differences between twoestimates resulted from different assumptions for two approaches.Based on benefit-cost analysis on HACCP for slaughter house, it is expectedthat HACCP program bring net benefits to slaughter house. In the future,benefit-cost analysis on HACCP could be improved by using better data on pricesand costs.
