Nitrofurans are used in the maintenance of bees for honey production. Nitrofurans are rapidly metabolized and covalently bound with proteins or peptides. 

It is possible to detect the conjugated metabolite as well as the parent drug with the Charm II system using a sequential binding assay. Results are obtained in less than 40 minutes including sample preparation. There are 4 nitrofuran drugs. These tests are for AOZ and AMOZ metabolites and parent drug.
