The screening of foodstuffs for antibiotic residues is an important aspect of food safety both from a quality control standpoint, (insuring the integrity of “ organic “ products) and to detect regulated or banned substances in imported foods. Current LC/MS methods are quite costly and require experienced personnel. An inexpensive, high resolution rapid screening technique has been developed for several sulfonamide antibiotics, including sulfamethazine, probably the single most popular vetinary drug. Using ACQUITY UPLC with UV detection, required detection limits for several sulfonamide compounds have been achieved in milk after solid phase extraction with run times less than two minutes.
