The effect of the administration of the mycotoxins OTA, ZEA and DON alone resp. in combination on animal health and the residue behavior of pigs from 50-60 kg living weight over 90 days was investigated in 4 separate studies. Due to its fast metabolisation the administration of 1000 ug DON resp. 250 ug ZEA per kg feed alone or in combination with other mycotoxins does not lead to detectable residues of these mycotoxins in organs and tissues. Therefore these mycotoxins should not be relevant to the consumer. There is an effect of the simultaneous administration of ZEA resp. DON on the metabolisation resp. secretion of OTA. OTA is of relevance from the point of view of residue toxicology.
