Abstract
Nowadays antibiotics are used on a large scale in animal farms and veterinary field without control. Antibiotics are used in treatment and prophylaxis of many diseases, and also for growth promotion. Studies ensured that the presence of antibiotic residues in different tissues and internal organs of animals lead to many hazards to Public health if these food stuffs of animal origin are used as human food. This research was done on materials from slaughtered animals (buffaloes, sheep and camels) collected from Balady and El-Moneib abattoir to know the incidence of antibiotic residues in tissues (muscles, liver and kidneys) at the slaughter time. This study included 50 buffaloes, 50 sheep and 50 camels; the weight of the sample ranged between 150-200 g from muscles, liver and kidneys, and transferred to the laboratory in sterile polyethelene bags.These samples were examined by microbiological method( Inhibition test) at pH 6.7 and 8. Five positive samples each from muscles of buffaloes and sheep were examined after boiling at 100°C for 30 minutes and also were examined after freezing at -18°C to 20°C for five months for the determination of the percent of antibiotic residues every month. It was noticed that the incidence of antibiotic residues in directly slaughtered animals were low in camel samples (6%) when compared with those of buffaloes (4%-40%) and sheep (4%-14%). Moreover, the incidence of antibiotic residues in liver (14%-36%), (6%) and muscles (4%-10%), (4%-8%) of examined buffaloes and sheep were lower than kidneys (18%-40%), (10%-14%) of the same animals.
