Nitrofuran metabolite 3-amino-2-oxazolidinone residues in chicken liver: A screening study

Abstract

Enzyme Linked Immunosorbent Assay (ELISA) method has been implemented to screen the residues of nitrofuran metabolite AOZ in chicken livers obtained from local markets in Bursa province of Turkey. For this purpose, ELISA kit specific for this metabolite was used. ELISA screening demonstrated the presence of AOZ residues in 11 of 90 chicken liver samples, with a positive rate of 12.2%. The residual level of nitrofuran metabolite AOZ in chicken livers ranged from 103.8 to 1027.8 ng kg(-1), having a mean of 212.2 ng kg(-1). Present results showed that the use of these compounds in broiler has the potential and public awareness should be raised to prevent the usage of AOZ in livestock production.
