Studies on the detection of sulfonamide residues in swine edible tissues

돈육내 sulfonamides의 잔류물질 검출에 관한 연구

The study was carried out to determine the residues of sulfonamides in swine edible tissues with high performance thin layer chromatography. For this purpose, the Rf values of sulfonamides in various solvent systems and the recovery rate of sulfameathazine from sampike saples were obtained. Thirty-four samples collected from meat market in Seoul were analyzed. The results obtained from the present study were followings: 1. The average recovery rate of sulfamathazine residues from spiked tissues 0.05, 0.1, 0.5 and 1mg/kg sample weight was 85%. 2. Two of 34 samples of pork for domestic consumption were reported to have been exceeded 0.05 ppm in sulfamethazine residues degree. 3. On the basis of the results, the degree of residues of sulfamethazine in swine meat for domestic consumption is seemed not to be dangerous for public health.
