Abstract

For the first time, this paper aimed to evaluate nine ionophore and synthetic coccidiostat residues in poultry muscle samples, obtained from different production types, by solid-liquid extraction followed by liquid chromatography with tandem mass spectrometry (LC-MS/MS). The fully validated methodology was successfully applied to a total of 101 chicken and turkey samples obtained from canteens, supermarkets, and home productions in Portugal. Halofuginone, diclazuril, decoquinate, narasin, lasalocid, and salinomycin were detected in 20.8% of the samples. Home raised samples showed a greater frequency, 47.1%. The synthetic coccidiostats halofuginone, diclazuril, and decoquinate were found in averages of 0.7 μg kg
