Ochratoxin A, a toxin produced by Aspergillus ochraceus, Aspergillus carbonarius and Penicillium verrucosum, is one of the most-abundant food-contaminating mycotoxins.It is also a frequent contaminant of water-damaged houses and of heating ducts.chratoxin A has a strong affinity for the brain, especially the cerebellum (Purkinje cells), ventral mesencephalon, and hippocampal structures. The affinity for the hippocampus could be relevant to the pathogenesis of Alzheimer's disease, and subchronic administration to rodents induces hippocampal neurodegeneration.
