Determination of Veterinary Drug Residues, Mycotoxins, and Pesticide Residues in Bovine Milk by Liquid Chromatography Electrospray Ionisation -tandem Mass Spectrometry.

ABSTRACT:

Introduction

Multi-class and multi-residue analyses are very complex procedures because of the physico-chemical properties of veterinary drug residues and other contaminants. The purpose of the study was to develop an analytical method for the sensitive determination of 69 analytes in bovine milk by liquid chromatography electrospray ionisation-tandem mass spectrometry.

Material and methods

Antimicrobial, anabolic hormone, lactone, β-agonist, mycotoxin and pesticide residues were analysed in 120 raw milk samples from different dairy farms in North Macedonia. Stable isotopically labelled internal standards were used to facilitate effective quantification of the analytes.

Results

The linear regression coefficients were higher than 0.99, the limits of detection ranged fr
