Ochratoxin A

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. Human exposure can occur through consumption of contaminated food products, particularly contaminated grain and pork products, as well as coffee, wine grapes, and dried grapes.
