豚肉에서의 抗生劑 殘留와 回收에 關한 硏究

A study on antibiotic residues and their recovery in pork tissues

Groups of pigs were injected intramuscularly once daily for two days with therapeutic dose of penicillin (3㎎/㎏ Body weight), ampicillin(10㎎/㎏ B.W.) or chloramphenicol (5.5㎎/㎏ B.W.) and killed by stunning 24 hour after the second injection, Samples of gluteus muscle(opposite injection site), kidney, serum and urine were collected when slaughtered and determinded antibiotic residues by microbiological assay. The results were as follows; 1. All samples of muscle, kidney and serum in pigs injected with penicillin, ampicillin or chloramphenicol were found in positive reaction by microbiological assay plate technique. 2. In all pigs injected with penicillin, the antibiotic was present at levels of ＞0.04㎍/g tissues. 3. In the pigs injected with ampicillin, ＞0.04㎍/g tissues was found in 3/4 sites; but 5 urine samples were all negative. 4. muscle, kidney and serum have little commercial value samples of them are most suitable for antibiotic assays.
