From Ohio to Kansas, corn is selling at startlingly high prices, so high that they are signaling the United States will run short of corn this summer.

If it does run short, the impact could be felt worldwide. Sales to big export customers like Mexico, Japan, South Korea, and China could take a hit as America grows 40 percent of the corn sold on the world market.

Domestically, sky-high prices could have U.S. millers suspending operations. If corn for feed costs too much than milk, egg and meat farmers could curtail production leading to higher food prices.
