Even the best management of agricultural strategies cannot totally eradicate mycotoxin contamination.
Mycotoxins are secondary metabolites produced by filamentous fungi which have a negative impact on animals and humans, either by ingestion, inhalation or skin contact.
Mycotoxins have been isolated from silages that did not show visible mould contamination. Therefore, in practical terms, it cannot be guaranteed that visually sound silage does not contain mycotoxins, as these substances are odourless and invisible. If silage shows spoilage symptoms, it should not be fed to animals to prevent the occurrence of mycotoxicoses, as there is a high probability of mycotoxin contamination in these cases. Instead, it is strongly recommended to discard spoiled silage (30 - 40 cm of the surface).
Methods to reduce mycotoxin contamination on field include ensiling, and the use of resistant plants.
