Animal feeding stuffs: Methods of sampling and analysis - Screening and determination of authorized coccidiostats at additive and 1 % and 3 % cross-contamination level@ and of non-registered coccidiostats and of one antibiotic at sub-additive levels@ in c
This document specifies a high performance liquid chromatographic ?C tandem mass spectrometry (LCMS/ MS) method for the simultaneous screening and/or determination of the eleven authorized coccidiostats (halofuginone@ robenidine hydrochloride@ nicarbazin@ diclazuril@ decoquinate@ monensin sodium@ salinomycin sodium@ narasin@ lasalocid sodium@ semduramicin sodium and maduramicin ammonium alpha) contents in poultry@ cattle and pig feed at additive and cross-contamination levels and of five non-registered coccidiostats (ethopabate@ clopidol@ ronidazole@ dimetridazole and amprolium) at sub-additive levels and for the screening of the prohibited furazolidone antibiotic at sub-additive level@ in the same matrices. The range of application of the method is fit for the purpose of the screening and determination of all eleven coccidiostats at the values set by European legislation@ of the non-registered coccidiostats and of the screening of the banned antibiotic.
