Abstract
Analytical methods were developed and validated to determine residues of veterinary drugs in buffalo milk and meat, using the QuEChERS method and gas chromatography-mass spectrometry. Both milk and meat, at 2 g of sample, 4 mL of acetonitrile, 0.8 g of MgSO4 and 0.2 g of NaCl, were used in the liquid-liquid partition, whereas 50 mg of C18, 50 mg of PSA and 150 mg of MgSO4 were employed in the dispersive solid-phase extraction (d-SPE). The methods showed sensitivity, precision and accuracy. The quantitation limits were in agreement with the maximum residue limit established by the Codex Alimentarius, FAO and WHO. (AU)
