A high-throughput UPLC-MS-MS Bio-analytical method for the analysis of veterinary pharmaceutical residues in Chicken Tissues, Application of efficient-valid-green (EVG) Framework as a Competence Tool

Abstract

Antibacterial medications are receiving the most attention due to hypersensitivity reactions and the emergence of bacterial mutants resistant to antibiotics. Treating Animals with uncontrolled amounts of antibiotics will extend beyond their lives and affect humans. This study aims to determine the concentration of the residues of sulfadimidine, sulfaquinoxaline, diaveridine, and vitamin K3 in the tissues of poultry (muscles and liver) after treatment with the combined veterinary formulation. A UPLC-MS-MS method was developed using Poroshell 120 ECC18 and a mobile phase composed of acetonitrile and distilled water, containing 0.1 % formic acid, in the ratio of (85:15 v/v) at a flow rate of 0.6 mL/min. Sample extraction solvent was optimized using response surface methodology (RSM) to be acetonitrile: methanol in the ratio (49.8: 50.2 v/v), and the method was validated according to the FDA bioanalytical method validation protocol over the range (50–1000 µg/Kg) for sulfaquinoxaline and (50–750 µg/Kg) for the other 3 drugs. The greenness of the sample preparation and analytical method was assessed by applying Analytical Eco-scale (AES) and AGREE coupled with AGREEprep. The Competence of the study was evaluated via the EVG framework known as Efficiency, validation, and greenness, to achieve a balance point represented by a radar chart. The method was applied to decide the time required for poultry products to be safe for human use after administration of the studied drugs. It was found that, after the administration of the last dose, minimally 7 days are required till the levels of the drugs drop to the maximum residue limit determined by the FDA/WHO in animal tissues.
