"Japanese self-support rate of foods have been very low, and the a mount of farm products imported from abroad is still increasing. Safety of foods is one of the most important problem. But a lot of imported farm products are treated by pesticides after these harvest in order to transport for long distance and preserve for a long time, which is called ""Post Harvest"". Then we investigated pesticides in imported citrus fruit, dry fruit, rice and flour. In the rind of citrus fruit out of 23 samples, TBZ was detected at 0.2～37 ppm from 17 samples, OPP at 0.1～16 ppm from 19 samples, DP at 0.1～140 ppm from 21 samples, supracide at 0.02～5.2 ppm from 7 samples, diazinon was at 0.03 and 0.08 ppm from 2 samples. But in these flesh it was scarcely detected. In process foods made from citrus fruit such as marmalade TBZ was detected at 0.1～54 ppm from 6 samples out of 11. In dry prune malathion was detected at 0.056 ppm from a sample out of 10. In raisin captan was detected at 2.3 and 2.8 ppm from 2 samples out of 12. In rice malathion was detected at 0.017～0.062 ppm from 3 samples out of 17. But none of organic phosphorus compounds were detected in Japanese 6 samples,In flour out of 18 samples reldan was detected at 0.01～0.037 ppm from 9 samples, malathion at 0.016～0.059 ppm from 8 samples. 8 samples were detected reldan and malation at the same time. But 2 samples which indicated Japanese products were not detected.At measurements we took as simple and speedy methods as possible."
