A UPLC-MS/MS based multiresidue, multiclass method was developed and validated for the simultaneous confirmation and quantification of  24 analytes of  quinolones including fluoroquniolones, sulfonamides and tetracyclines and its epimers in crustaceans (shrimp tissue) following the European Union’s (EU) performance criteria (CD 2002/657/EC).

Samples were extracted using a simple method by acidified acetonitrile (0.5 mL of 0.1% formic acid in 7 mL of Acetonitrile) with a clean-up using n-hexane and methanol, followed by Ultra Performance Liquid Chromatography electrospray tandem mass spectrometry (UPLC-ESI-MS/MS) within 8 minutes using positive mode. The method validation as per CD 2002/657/EC and demonstration through proficiency testing provided evidence that the method is suitable to be applied in detection and quantification of 24 antibiotic residues in routine analysis of fish and fishery products.
