Abstract
In total, 400 retail samples of chicken meat, including liver, breast, and frozen poultry products (burger-nagets, and lunchon), were gathered from several Egyptian supermarkets (Beni Suef). Each chicken sample was represented by a subsample made up of frozen poultry product, pooled edible organs, and meat (breast). The samples were divided into distinct plastic bags, given numbers, and transported to the National Research Institute’s central laboratory in plastic ice containers. They were then kept there until the time of analysis, when ELISA and a microbiology device were used to quantitatively determine the presence of various antibiotic residues (macrolide, tetracycline, quinolone, and beta-lactams) in each sample.
Tetracycline was found in 55 (68%) of the liver samples and 51 (63%) of the breast samples that were tested; the maximum residual levels were 25.200 and 20.500 mg/kg for the liver and breast, respectively (p 0.05).
While fluoro-quinolones were found in 58 (73%) of the examined liver samples and 51 (63%) of the examined breast samples, approximately 58 to 85% of the samples contained ciprofloxacin residues with the maximum residual levels of Danafloxacin, Sarafloxacin, Flamequine, and Ciprofloxacin being 35, 75, 55, and 65 mg/kg .
Streptomycin was found in 58 (72%) of the liver samples and 45 (56%) of the breast samples that were tested. The maximum residual levels were 18.100 and 11.400 mg/kg in the liver and breast samples, respectively.
Penicilline was found in 48 (60%) of the liver samples and 43 (53%) of the breast samples that were tested. The maximal residual levels were 21.600 and 19.600 mg/kg for the liver and breast, respectively.
the meat of fresh domestic broiler chicken carcasses sold in stores has various antibiotic residues. The maximum residual levels of tetracycline, streptomycin, erythromycin, and penicillin in the samples were 20.500, 11.400, 30.500, and 19.600 mg/kg, respectively. This result demonstrates that the residual level of each antibiotic group is higher in the liver than the breast muscle, with erythromycin being the antibiotic with the highest residue in the liver and breast tissue.
Erythromycin was found in 53 (66%) of the liver samples and 46 (57%) of the breast samples that were tested; the highest residual levels were 43, or 30.500 mg/kg, for the liver and breast, respectively (p 0.05). with mean values in the liver and breast of 13.103±751.614 and 7.81±.022, respectively.
Detecting antibiotic residue in poultry products (lunchon, burger, and nagets) 80 samples for each of high and poor quality of frozen product tested were negative for antibiotic residues (fluroquinilone group , streptomycin ,penecilline and erythromycin and tetracycline ).
The suggestues results to produce high quilty chicken broiler meat was dissuced as well as the significance of detected residue in chicken meat was showed.
