Abstract

The purpose of the present survey was to evaluate the antibiotic residues in meats and internal organs such as muscle, liver, heart, kidney and spleen of cattle (n=59) and pigs (n=115). The EEC-4-plate-method were employed. The results were obtained as follows ; 1. In BS 6.0, BS 7.2 and BS 8.0 used as media to detect antibiotic residues, the zone($M{\pm}SD,$ cm) of bacterial growth inhibition was narrow($1.40{\pm}0$) in meats, whereas the zone was wide($1.69{\pm}0.25-1.88{\pm}0.23$ and $1.58{\pm}0.18-1.86{\pm}0.15$ in cattle and pigs, respectively) in internal organs. But in SL 8.0, it was difficult to detect the zones ($0-1.40{\pm}0$) of both meats and internal organs. 2. Residues of antibiotic in beef and pork were rarely detected in BS 6.0, BS 7.2 and BS 8.0 (range 1.7-11.9% and 2.6-4.3%, respectively), whereas residual percentages of internal organs were relatively higher(range 69.5-96.6% and 43.5-84.3%, respectively). But in SL 8.0, it was not detected in both beef or pork, whereas they were 0-13.6% and 0-4.3% in interanal organs.
