Efficiency of application and Biosafety of products of slaughter of broiler chickens when using antibiotics

Abstract

The article presents experimental data on the detection of antibiotics enrofloxacin and ciprofloxacin in poultry meat. We also analyzed the timing of removal of these antibacterial drugs from the poultry body and assessed the biological safety of products of slaughter of broiler chickens. These studies were conducted in the Syrian Arab Republic. It is established that in the free sale cases of sale of chicken meat containing enrofloxacin are detected. This is probably due to the fact that poultry is slaughtered before treatment is completed. On the contrary, such an antibacterial drug as ciprofloxacin is found in single samples and in minimal concentrations. Comparative data on the accumulation of enrofloxacin in the thoracic and femoral muscles are also provided, and maximum concentrations of this drug in the muscle tissue of broiler chickens are established. It was found that the concentration of ciprofloxacin in samples taken from all four districts is below 18 mcg/ kg, which is below the maximum allowable (100 mcg/kg). The concentration of enrofloxacin in the femoral muscle samples in the fourth district was higher than the maximum permissible limits (100 mcg/kg). In addition, the average concentration of enrofloxacin in the fourth district exceeded the maximum allowed limits without taking into account the average concentration of ciprofloxacin in the same sample. The low concentration of ciprofloxacin compared to enrofloxacin, as well as the absence of high concentrations of the former, may indicate that the bird was not treated with ciprofloxacin, but it could be a product of enrofloxacin metabolism in birds.
