Abstract
Antibiotics, which are commonly used to treat human illnesses, are also used in animals for therapy, prophylaxis, and growth promotion. Sub-therapeutic antibiotic doses have typically been utilized for the last-mentioned purpose, which has contributed to resistance development. According to scientific data, certain antibiotic applications in food-producing animals can result in antibiotic resistance in intestinal bacteria, which can then be passed to the general population, causing treatment-resistant sickness. These antibiotic applications can also result in antibiotic resistance in non-pathogenic bacteria, whose resistance genes can be passed to disease-causing bacteria, resulting in antibiotic-resistant illnesses in people. Thus, this study assessed the antibiotics residues in raw meat sold in 6 slaughter houses in Kaduna State. The study is a descriptive cross-sectional study involving 6 slaughter houses in Central market Kaduna. Muscle, Kidney and liver samples were collected from each slaughterhouse. The antibiotic residues in the meat samples were analyzed using high performance liquid chromatography (HPLC) for tetracycline, ciprofloxacin and oxytetracycline residue results were presented in charts and tables. 18 different samples of beef (6 Muscles, 6 Liver and 6 Kidney) collected from abattoirs and meat vendors, the results shown that all beefs use three or more antimicrobial drugs. This research result revealed that 4(67%) tetracycline (oxytetracycline)were detected in meat samples at higher concentration), Oxytetraxycline (352.88 ± 221.58) of muscles is higher than (332.2± 217.05 of Liver and (263.33 ± 153.98) of Kidney is lower to muscles and liver. The Concentration of oxytetracycline were highest in muscles in samples 2. 3 and 6 which is above the WHO maximum residual limit. The concentration of streptomycin in the muscle, liver and kidney were detected (182.78 ± 56.23), (169.2 ± 58.39), (155.1 ± 50.20) but were within WHO Maximum residual limit. These high level of oxytetracycline residues in greater proportion of muscle samples destined for human consumption beyond MRLs could be as a result of the abuse of veterinary drugs as commonly practiced among livestock producers and vendors without observing withdrawal period prior to slaughter. The high-contamination rate of beef meat in the study areas is likely that consumers experience a high risk of exposure to drug residues.
