Abstract
An analytical method was developed for identification and quantification of zilpaterol in bovine liver, meat, heart, and kidney, using liquid chromatography coupled to quadrupole-Orbitrap high-resolution mass spectrometry (LC-Q-Orbitrap HRMS). It was validated in accordance with Commission Implementing Regulation (CIR) EU 2021/808 at six different concentrations, ranging from 0.1 to 5 μg/kg. The mean recoveries ranged from 71% to 99%, while the decision limit (CCα) and detection capability (CCβ) ranges were 0.11-0.12 μg/kg and 0.13-0.15 μg/kg, respectively. The method demonstrated good linearity (R2 > 0.9996) and the limits of detection (LODs) and of quantification (LOQs) were in the range of 0.015-0.061 μg/kg and 0.025-0.091 μg/kg, respectively. Out of 200 samples collected from local markets in Egypt, 17 contained zilpaterol residues. Liver samples revealed the highest detection frequency (26%), followed by meat (6%), at mean concentrations of 2.64 and 1.93 μg/kg, respectively.
期刊介绍:
Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling.
Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment.
The scope is initially restricted to:
Additives - food colours, artificial sweeteners, and preservatives;
Residues – veterinary drug and pesticide residues;
Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging.
Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet.
Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
