Monitoring of coccidiostat residues in eggs according to the EU legislation using liquid chromatography tandem mass spectrometry

摘要

Coccidiostats cover a various range of pharmaceutical substances used in the treatment of an infectious disease called coccidiosis caused by a protozoan parasite. Several coccidiostats are licensed for use in the EU as feed additives for treating infection in poultry, but are not authorized for laying hens. The occurence of carry-over of feed additives in non-target feed or improper use on farm may result in residues of coccidiostats in eggs.
