Memorial Day barbecues are about to become more expensive for Americans, thanks to a misguided federal policy that props up biofuel makers and corn farmers – at the expense of poultry producers and the customers who buy their chicken.

The price of corn feed is generally the most expensive part of raising chickens, making any policy that artificially inflates corn prices devastating to America’s poultry farmers and costly to consumers. The recent announcement by the Trump administration that it will permit the year-round sale of E15 (gasoline blended with up to 15 percent ethanol) will create just that kind of price inflation.
