Abstract
Zeranol and two Fusarium toxins, α-zearalenol and ß-zearalenol, were confirmed by gaschromatography/mass spectrometry (GC/MS) in bovine bile samples referred to this laboratory for analysis. No evidence of zeranol abuse was found on-farm. Given the recent suggestion that zeranol might arise from the metabolism of these Fusarium toxins, and the finding of zeranol in bovine and ovine urine across the EU, it was concluded that the residues had arisen as a result of natural metabolism.Keywords
