Determination of the furaltadone metabolite 5-methylmorpholino-3-amino-2-oxazol...
Descrição
Abstract The use of nitrofuran veterinary drugs as antibacterial compounds in food-producing animals has been banned in the EU since 1995. As nitrofurans are extensive and rapidly metabolized, control of their illegal use in animal production must be done in edible tissues by LC-MS/MS analysis in order to determine persistent tissue-bound metabolites. The introduction during 2002 of the multi-residue detection of nitrofuran tissue-bound metabolites by LC-MS/MS for nitrofuran control in Portuguese Residues Monitoring Plan, revealed the presence of 5-morpholinomethyl-3-amino-2-oxozolidinone (AMOZ), the bound residue of furaltadone, in a large number of samples, namely in meat poultry samples. From the 226 analysed samples in the last 4 months of 2002, 78 were non-compliant due to the presence of AMOZ (61 broilers, 11 turkeys, 5 quails and 1 pig). In this context, the aim of this paper is to describe the analytical data obtained on meat samples collected from various animal species under official Portuguese control for nitrofuran drug residues during the so-called “Portuguese nitrofuran crisis”. http://dx.doi.org/10.1007/s00769-007-0305-2
