Tetracycline and ciprofloxacin multiresidues in beef and chicken meat samples using indirect competitive ELISA.

In livestock and poultry, broad-spectrum antibiotics such as tetracyclines and fluoroquinolones are widely used; thus, controlling food productions made from these animals is a necessary task. Meat may contain residues of antibiotics, even in low concentrations, which can cause a selection pressure for antibiotic resistance. Therefore, measurement of amounts of antibiotics in meat is of major importance.
