Citrinin
Citrinin is a mycotoxin originally isolated in 1931 by Hetherington and Raistrick from a culture of Penicillium citrinum. It has since been found to be produced by a variety of other fungi that 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.
