This paper describes a rapid method for confirming residues of thyreostats in meat-based baby foods by using liquid chromatography - dual polarity electrospray - tandem mass spectrometry (LC-ES(±)-MS/MS). Six thioureylenes, belonging to the group of thiouracil and imidazole, were selected for this work: thiouracil (TU), methylthiouracil (MTU),(More)
