Citrinin is a mycotoxin originally isolated from Penicillium citrinum. It has since been found to be produced by a variety of other fungi which are found or used in the production of human foods, such as grain, cheese, sake and red pigments. Citrinin has also been found in commercial red yeast rice supplements, and also in Aspergillus niveus and Aspergillus terreus (Hugo Vanden Bossche, D.W.R. Mackenzie and G. Cauwenbergh. Aspergillus and Aspergillosis, 1987).

Citrinin is usually found together with another nephrotoxic mycotoxin, Ochratoxin A. Citrinin is also reported to possess a broad spectrum of bioactivities, including antibacterial, antifungal, and potential anticancer and neuro-protective effects in vitro[1][2].
