Where there's stored corn, there's always concern over aflatoxin. However, a new corn line with greater resistance to the fungal toxin may be available to you within the next few years. U.S. Department of Agriculture scientists developed the corn and released it to seed companies and public research institutions for breeding purposes.

Corn contaminated by aflatoxin can be dangerous to livestock and humans if it is inhaled or ingested in high quantities. The new corn line, Mp715, has lower levels of infection with the fungus and later contamination with the toxin than traditional varieties. It may help spur the availability of commercial hybrids with strong aflatoxin resistance.

"Corn hybrids that resist both the fungus and its toxin are widely considered the most efficient and reliable way to reduce the accumulation of aflatoxin in corn grain," says USDA's Agriculture Research Service geneticist W. Paul Williams, who helped create this new corn line.

Though it has been released, currently there is no aflatoxin-resistant commercial hybrid corn available to producers, and it will take several years before hybrids using Mp715 are available.
