title: Postmortal degradation of furazolidone and furaltadone in edible tissues of calves.
abstract: Rapid and complete postmortal degradation of furazolidone and furaltadone occurred in liver, kidney and muscle tissues of veal calves. Different degradation half-lives were observed between these tissues, the mean ranging from less than 7 minutes to 63 minutes. At 24 h after slaughter the parent nitrofurans were no longer detectable in edible tissues. For residue monitoring purposes plasma and/or urine can be used, if these matrices are treated in a specific way immediately after slaughter; muscle tissues and organs are unsuitable for residue monitoring of parent nitrofurans.
