Corn Export Cargo Quality Report 2012/2013

VI. TESTING ANALYSIS METHODS

USDA’s Federal Grain Inspection Service (FGIS) provided official grading and aflatoxin results from its normal inspection and testing procedures for each sublot corn sample collected. The corn samples (approximately 6 pounds/2700 grams) were sent directly from the FGIS field offices to the Illinois Crop Improvement Association’s Identity Preserved Grain Laboratory (IPG Lab) in Champaign, Illinois, for the chemical, physical factors, and DON testing. Upon arrival at IPG Lab, the samples were split into two subsamples using a Boerner divider. One subsample was analyzed for DON. The other subsample was analyzed for the chemical composition and other physical factors following either industry norms or wellestablished procedures in practice for many years. IPG Lab has received accreditation under the ISO/IEC 17025:2005 International Standard for many of the tests. The full scope of accreditation is available at http://www.pjview.com/ clients/pjl/viewcert.cfm?certnumber=1752.
