title: Applications of capillary electrophoresis to the determination of antibiotics in food and environmental samples.
abstract: In this paper we review applications of capillary electrophoresis (CE) to the determination of antibiotic residues in food derived from animals and in environmental samples. Although many CE methods have been used to determine antibiotics in the pharmaceutical field (drug quality control or therapeutic monitoring in biological samples), food and environmental applications have been increasing in recent years. Due to the maximum residue limits established by the EU, in Directive 2377/90/EEC, for foodstuffs of animal origin and considering the low levels that can be found in environmental or waste waters or soils, different strategies to increase sensitivity have been developed, including off-line preconcentration, on-line stacking modes to use higher sample volumes, or in-line solid-phase extraction. Also, several detection techniques, such as fluorescence, laser-induced fluorescence, electrochemical detection, or mass spectrometry have been used; the last of these also enables unequivocal identification of the residues, required by Commission Decision 2002/657/EC. All these aspects will be discussed in this paper, in relation to the main groups of antibiotics used in veterinary and human medicine, for which applications in food and environmental samples have been developed by using CE as an efficient alternative to liquid chromatography.
