For the effective control of pesticide residues in food commodities, appropriate measures for monitoring program are strategically needed from the viewpoint of available resources. If only food items of higher intake (more than 10 g per day) are chosen for monitoring, the number of food items decreases from 282 to 22 items, covering 77% of total food intake. Pesticides used in Korea were scored based on acceptable daily intake, specific toxicities, use volume, safety margin in residue limit, and analytical convenience. They were then grouped into four ranks after summing up the scores. When pesticides of higher risk priority were monitored, the inspection load decreased remarkably from 240 pesticides to 110 or 31 items. By limiting both the numbers of food and pesticide items, the efficiency in monitoring load increased up to 15-fold as compared with the total inspection.
