Mycotoxins are produced by moulds. One mould  species may produce many different mycotoxins, and the same mycotoxin  may be produced by several species.

Mycotoxins have the  potential for both acute and chronic health effects via ingestion, skin  contact, and inhalation. These toxins can enter the blood stream and the  lymphatic system. They inhibit protein synthesis, damage macrophage  systems, inhibit particle clearance of the lung, and increase  sensitivity to bacterial endotoxin. 

There is evidence  that they can cause cancers, kidney damage, gastrointestinal  disturbances, reproductive disorders and suppression of the immune  system.
