| Abstract | ||
| Contamination of edible animal products with veterinary drug residues is a potential health hazard for consumers. A method for extracting rafoxanide anthelmintic drug from sheep muscle was adopted based on a QuEChERS approach followed by high-performance liquid chromatography (HPLC-UV). The developed method has been fully validated according to the requirements of Eurachem-2014 by separating the standard anthelmintic drugs on a fast liquid chromatographic (FLC) reversed-phase column under the optimum separation condition. The mobile phase consists of solvents A and B, degassed with an ultrasonic bath to remove bubbles. The standard calibration curves (R²≥0.9961) were constructed with spiked certified reference materials (CRM) and blank tissues. The optimized approach was validated, yielding satisfactory results for all performance criteria in the tested matrix and obtaining relevant results for all performance parameters in the evaluated matrix. A multi-level calibration curve (1 to 1000 µg/kg) was used to establish instrument linearity for rafoxanide. The recoveries were 83%, the limit of quantification was 10 μg/kg, and the detection limit was 0.22 μg/kg. The results of the validation allowed for high sample throughput. The method is suitable for analysing selected anthelmintic drug residue, and repeatability and reproducibility expressed in relative standard deviation (RSD%) were obtained at values lower than 20%. None of the testers were greater than Maximum Residual Limits (MRLs) legally established by the European Union (EU). 13 (26%) (n=50) samples were below MRLs, and 37 (74%) (n=50) samples were below the LOD. | ||
