RISKS DUE TO MEDICATION OF FEED AND WATER IN ANIMAL FLOCKS

Goal of this contribution was a review concerning the different risks of application of drugs in food producing animals, excluding the devel opment of resistance in pathogenous bacteria. Especially the risks of displacements of drugs and additives during the process of production of medicated feeds and its use under field conditions are concerned. F urthermore water medication and its problems or risks are presented. T he onset of drug residues in food - inspite of the use of unmedicated feeds and water - is discussed for example as a consequence of contami nation of feeds (especially in wet feeding systems in pigs), the surro unding and/or litters.
