see second paragraph
Also from that page:
"The county grain elevator also acts as a warehouse for growers without sufficient on-farm storage to meet their marketing needs. Warehouses are licensed under either state or federal statutes, but, in either instance, warehouses must maintain corn of quality equal or better than that certified on warehouse receipts. Generally warehouse receipts are only issued for the standard U.S. Grades, which by implication means less than 20 ppb aflatoxin. Clearly, warehouses in high-volume areas must know the aflatoxin status of grain received. The cost of finding aflatoxin in corn or peanuts stored in a warehouse can be great....
The incidence data demonstrate the difficulty of assessing aflatoxin levels in a growing area. So far, aflatoxin contamination in midwestern corn has been limited enough that the natural consolidation of grain lots into larger shipments eventually diluted aflatoxin concentrations to less than 20 ppb most of the time. This would not apply to users drawing from localized high-risk areas. A much better early-warning system is needed to identify potential high-risk areas."

My corn is from Azurestandard.com. It is organic and human-grade. It comes across state lines.
Apparently if corn is to be shipped interstate it must comply with this:
"Corn that is contaminated with aflatoxin at levels greater than 20 ppb may not be sold for interstate commerce, "
from
http://www.ipm.iastate.edu/ipm/icm/2005/9-19/aflatoxin.html
Thus, it appears that the safest corn may be the corn that has gone through the grain elevators and had an unknown destination, rather than a local farmer who may or may not have tested his corn (of course you can ask them if they did).
Anyone concur?
