There again goes the media, planting the seeds of panic, with a subsequent increase in food prices. Is there anything else they want to increase the prices on?
If they set the stage for increases then it will give whoever an excuse to raise prices and we'll get a "See, we told you so", just like gas prices jump when someone in the Mideast burps.
I am a farmer. To my knowledge, most of the grain shipped by barge down the Mississippi is #2 corn for export.
Food grade corn is primarily moved by semis to the processors here in the midwest.
There are some cargo containers of IP grain moved, but it isn't the majority.
