Antibiotics and hormone-like anabolic agents use in order to intensify the production of chicken farms. These may reflect on formation the harmful chemical residues in their meat and offal. The purpose of the current study was to analyze some chemical hazards in local and imported chicken meat and their edible offal including: Quantitative assessment of ciprofloxacin and sulfonamide and growth promoters 17β-Estradiol. A total of 214 fresh and imported chicken carcasses were purchased from different commercial chicken markets at Ismailia governorate, Egypt and Bahrain. 10 grams of meat sample was blended, centrifuged, homogenized, extracted and analyzed by HPLC to estimate the concentration levels of ciprofloxacin and 17β-Estradiol residues. Spectrophotometer used to detection of sulfonamide residues. The mean concentrations ciprofloxacin values for Egyptian and Bahrainis chicken meat were; 0.339 ± 0.026 and 0.126 ± 0.031 µg/g respectively. While, the mean concentrations ciprofloxacin values for Egyptian and Bahrainis chicken offal were; 0.65 ± 0.075 and 0.545 ± 0.045 µg/g respectively. The mean concentrations Sulfadiazine values were; 0.020 ± 0.003 and 0.006 ± 0.002 µg/g respectively while, in chicken offal were 0.045 ± 0.020 and 0.025 ± 0.015 µg/g respectively. The mean concentrations 17β-Estradiol values for chicken meat were; 1.626 ± 0.076 and 1.593 ± 0.069 µg/g respectively. While, in chicken offal were 2.60 ± 0.089 and 2.95 ± 0.075 µg/g respectively. Results of this study observed that the Egyptian chicken meat under investigation contained several chemical residues than Bahrain samples which may represent a sever public health hazards for consumers if increase their daily intake level of chicken meat. In addition to, such chemical residues were more concentrated in the chicken offal than chicken meat. More attention from the concerned authority must be considered in controlling antibiotics and hormone-like anabolic agents at chicken farms.
