Nitrofurans are synthetic broad-spectrum antimicrobial agents which are rapidly absorbed and extensively bio-transformed, giving rise to protein-bound residues. The 3,5-dinitrosalicyclic acid hydrazide (i.e. DNSH) metabolite is readily transformed from the parent nifursol. The metabolites are routinely used as marker residues for control of the prohibited treatment of food-producing animals with nitrofurans in the European Union (EU)
