Ochratoxin A is a widespread, naturally occurring mycotoxin that is produced by some fungi, especially by Aspergillus and Penicillium, and is a very common food contaminant found on grains, coffee beans, nuts, decaying vegetation, moldy cereals and animal feeds. This toxin is used in research as an experimental teratogen and carcinogen. Ochratoxin A is reasonably anticipated to be a human carcinogen and may be associated with an increased risk of developing urinary tract tumors. (NCI05)"}]
