Dry weather means that farmers are harvesting their corn a little earlier this year. Agriculture Commissioner Steve Troxler is encouraging farmers to have their corn tested for aflatoxin to prevent contamination of feeds and food. Aflatoxin is a byproduct of the mold Aspergillus flavus, and can be harmful to both humans and livestock. Some farmers may need to have corn samples tested for crop insurance or quality assurance purposes. These samples must be submitted to a grain marketing location certified by the U.S. Department of Agriculture. The tests cost $22.20 per sample. For insurance or quality assurance purposes, farmers must submit a 5-pound sample of shelled corn by mail, UPS or FedEx to a USDA-certified grain marketing location.  Farmers who grow or buy bulk corn to feed to their own animals can have it tested for free by the N.C. Department of Agriculture and Consumer Services’ Constable Laboratory in Raleigh. This Laboratory is not on the Risk Management Agency’s approved testing facility list; therefore, results from this location will not be accepted for insurance claims.
