Aflatoxins are potent, naturally occurring toxins that sometimes develop in corn and certain other crops. Aflatoxins are also among the most carcinogenic substances known. There are well-defined limits on how much aflatoxin is allowable in corn, based on the intended end use. For example, corn intended for human consumption must have less than 20 ppb (parts-per-billion!). More information on aflatoxin can be found in the UK Extension publication, Aflatoxins in Corn, ID-59, at http://www.ca.uky.edu/agc/pubs/id/id59/id59.pdf.
