Extraction of oxytetracycline starting from the meats of chickens and identifications by thin layer chromatography

Use of antibiotics in the poultry also suspected as one of the cause of the emergence of resistance to antibiotics of some bacteria what causes risks on human health continuation of persistence of the residues in the foodstuffs. We were interested in detected the presence qualitatively of oxytetracyclin in samples of muscle and liver of chicken by the use of the techniques of thin layer chromatography. Although, These results are satisfactory, it is always necessary to prevent the dangers which cause the risks of the residues of oxytetracycline on health. (Author). 20 refs
