The present studies were carried out to determine antibiotics residues in pork and beef muscles by EEC-4-plate and HPLC. A total of 2,534 samples of pork muscles and 1,070 samples of beef muscles from slaughter houses were collected in Gyeongnam area from January to December, 2001. The results were summarized as follows; 1. Recovery rates of TCs, Sulfa drug, Penicillin G from fortified pork and beef muscles ranged as 68.79～98.24%, 78.21～94.58% and penicillin G 63.35～67.24% respectively, by HPLC. 2. Antibiotics residues were detected in 36 sample(1.42%) of pork muscles, 29 sample (2.71%) of beef muscles by EEC-4-plate. 3. Detection rate of antibiotic residues 14 samples(0.55%) and 26 samples(2.43%), in pork and beef muscles, respectively by HPLC. Concentration of residues in 22 sample(2.06%) of beef muscle were higher than tolerance level in korea. 4. Antibiotics detected were sulfamethazine(47.37%), tetracycline(15.79%), oxytetracycline (15.79%), penicillin G(15.79%), sulfamerazine(5.26%) in pork muscle samples and oxyteracycline (37.21%), penicillin G(30.23%), sulfamethazine(20.93%), tetracycline(4.65%), sulfamerazine (2.33%), sulfadimethoxine(2.33%), sulfaquinoxine(2.33%) in beef muscle samples.
