Review on immunoanalytical determination of tetracycline and sulfonamide residues in edible products.

The state of the art of immunoanalysis for the determination of tetracycline and sulfonamide residues in food products is reviewed. Special attention is paid to the design and synthesis of haptens, providing an overview of the efforts spent on developing antibiotic screening methods to determine residue levels in agreement with the legislation. The results and observations published, focused on tetracycline and sulfonamide enzyme-linked immunosorbent assays, are discussed.
