      A review of analytical methods for the determination of aminoglycoside and macrolide residues in food matrices
      Tara MCGLINCHEY*, P.A. RAFTER, Fiona REGAN, D. GILLIAN, P. MCMAHON (*Department of Agriculture, Fisheries & Food, Central Meat Control, Backweston Laboratory Complex, Youngs Cross, Celbridge, Co., Kildare, Ireland)

      Anal. Chim. Acta 624 (1), 1-15 (2008). Aminoglycosides and macrolides are important antibiotics for veterinary medicine and are widely used in the treatment of bacterial disease, and as feed additives for growth promotion. As a result the European commission set strict criteria for monitoring residues and requires testing for low levels of aminoglycosides and macrolides in foods. Therefore the development of fast, reliable, and sensitive methods for the extraction and subsequent analysis of these antibiotics is of great interest. The review discusses analytical methods for both extraction and determination of antibiotics in various food matrices focusing on the last 10 years. Extraction and clean-up methods such as deproteinization and solid-phase extraction are described, and various screening methods including TLC, EI, CE, microbiological assays, and LC combined with MS are reviewed.
