Antibiotics are commonly used as food additives in broiler farms and their use tends to be excessive regardless and incorrect that can leave some antibiotic residues in chicken meat. The aimed of this study was to analyze on  antibiotic residues level amoxicillin and tetracycline in chicken meat sold in Medan. The antibiotic residues analysis was conducted by extracting the antibiotic from chicken meat with water and acetonitrile (2:8, v/v) and detected by high performance liquid chromatography-mass spectrometry detector using C-18 column (4.6 mm i.d., length 30 mm, particle size 1.8 µm) at 35 oC, with the mobile phases,  0.1 % formic acid solution in water and 0.1 % formic acid solution in methanol with gradient elution technique at a flow rate of  0.5 ml/minute. The result exhibited that the chicken meat that were collected from five  markets  in Medan apparently contained antibiotic residues  tetracycline . The level of  tetracyclin residue in chicken meat was  0.1157-1.4436 µg/g, which exceed the maximum level  for tetracyclin residue allowed in foodstuffs of animal origin which is 0.1 ug/g.   Keywords: residue, antibiotic, amoxicillin, tetracycline, chicken meat
