A total of 450 samples comprising 150 each of muscles, livers and kidneys were collected from 150 sheep carcasses in Kuwait and tested by both Rapid Premi®Test kits for rapid detection of antimicrobial-positive samples, and the High-performance liquid chromatography (HPLC) for residual determination of amoxicillin, tetracycline, oxytetracycline, and tylosin. Premi test revealed that 82%, 64% and 100% of the muscle, liver and kidney samples examined, respectively were positive for antimicrobials. HPLC analysis revealed mean concentrations (µg/kg) of 45.26, 148.17, 103.18, and 71.80 for amoxicillin, oxytetracycline, tetracycline, and tylosin respectively in muscles; 64.43, 263.15, 177.04, and 112.94, respectively in livers; and 53.12, 368.21, 196.40, and 138.63, respectively in kidneys. Although many samples exceeded the maximum residue limit (MRL) of Codex Alimentarius, the assessment of dietary exposure to the antimicrobials tested through consumption of sheep meat and organs did not constitute any health hazards in the different age groups of Kuwaiti population.
