Detection of antibiotic residues in poultry products in Al Bayda, Libya.

Abstract

As a result of the absence of health control on poultry farms by the competent authorities and our knowledge of the excessive use of antibiotics without taking into account the drug withdrawal period, an HPLC device was used, which was conducted in the central laboratory of the Veterinary Teaching Hospital at Omar Al-Mukhtar University, to study and identify four types of antibiotic residues ( Tylosin, erythromycin, colistin, enrofloxacin). 120 birds were collected and marketed at sales points in the city of Al-Bayda and its suburbs, designated for selling poultry. After the slaughtering and processing process, all samples were examined. The results showed 70 (58%) positive samples. Of the 40 chest muscle, liver, and kidney samples tested, 17 (24%) were positive for the antibiotic tylosin, 11 (15%) were positive for the antibiotic erythromycin, and 7 (15%) were positive for the antibiotic Erythromycin. For the antibiotic erythromycin. 7 (10%) of the kidney samples were positive for erythromycin and 19 (27%) of the samples were positive for tylosin, while 14 (20%) of the chest muscles were positive for tylosin and 2 (2.8%) were positive for erythromycin. No colistin or enrofloxacin residues were detected. All samples were analyzed by HPLC. Among the four antibiotics detected, tylosin was the most abundant antibiotic in poultry samples (71.4%), followed by erythromycin (28.5%). The highest percentage of antibiotic residues was in the liver at 28 (40%), followed by the kidneys at 26 (37%), then the chest muscles at 16 (22.8%).
