| Abstract: A multiresidue method for detecting and quantifying sulfonamides (sulfapyridine, sulfamerazine, sulfathiazole, sulfamethazine, sulfadimethoxine, sulfamethoxazole, and sulfamethoxypyridazine) and trimethoprim in tilapia fillet (Oreochromis niloticus) using liquid chromatography coupled to mass spectrometry was developed and validated. The sample preparation was optimized using the QuEChERS approach. The chromatographic separation was performed using a C18 column and 0.1% formic acid in water and acetonitrile as the mobile phase in the isocratic elution mode. Method validation was performed based on the Commission Decision 2002/657/EC and Brazilian guideline. The validation parameters evaluated were linearity (r>=0.99); limits of detection (LOD)... |

| Introduction: Sulfonamides (SAs) have been employed in fish farming for the treatment of bacterial diseases. However, residues of SAs are a concern because of their potential risk to human health. Thus, the residue depletion of sulfamethazine (SMZ) was evaluated in Nile tilapia treated with medicated feed, and the withdrawal period and the maximum level of bioaccumulation (MLB) in the muscle were calculated. |
