Detection of antibiotics in feed by bioactivity based analysis [German]

摘要

The general confusion of customers in Germany with respect to the consumption of meat has drastically increased in the recent past caused by press releases on BSE of cattle. The trend to increased consumption of pork derived therefrom was significantly reduced by publications dealing with residues of antibiotics brought about by legal or illegal additives in feed. A bioautographic method has been developed for a most simple, selective and sensitive analysis of antibiotics subsequent to a thin-layer chromatographic separation based on an analysis of bioactivity (1). Meanwhile, the necessary components are commercially available in form of a testkit (Chrom Biodip(R) Antibiotics). The applicability e.g. for the analysis of feed is demonstrated with an actual example.
