Ochratoxin A—a toxin produced by different Aspergillus and Penicillium species — is one of the most-abundant food-contaminating mycotoxins.[1] It is also a frequent contaminant of water-damaged houses and of heating ducts.[2][3] 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.[4][5][6] The toxin has been found in the tissues and organs of animals, including human blood and breast milk.[7] Ochratoxin A, like most toxic substances, has large species- and sex-specific toxicological differences.[5]
