Iowa is in a state of emergency due to a highly contagious strain of avian flu called H5N2. Gov. Terry Branstad enacted the proclamation Friday after more than 20 confirmed or presumed outbreaks at commercial poultry facilities around the state.

This very contagious H5N2 has a high mortality rate among poultry, and therefore infection of commercial flocks is economically devastating to producers. So far roughly a quarter of Iowa's nearly 60 million laying hens have been affected by the virus.

UPDATE: The United States Department of Agriculture has confirmed H5N2 in a Sioux County flock of 1.7 million hens. The USDA has not yet confirmed the presence of avian flu in the other four suspected flocks.

More than 6 million hens and juvenile chickens in northwest Iowa will be euthanized pending final confirmation of H5N2. The Iowa Department of Agriculture reports a total of five flocks may be affected by this highly pathogenic strain of avian flu.

Nearly all gasoline sold in the U.S. contains up to 10 percent of ethanol—a corn-based liquid often added to gasoline. As a renewable fuel ethanol reduces the amount of petroleum-based gasoline on the market and many farmers receive subsidies to grow corn for the biofuel. But now the Environmental Protection Agency is considering a reduction in the required amount of ethanol for the country's gasoline supply.  Harvest Public Media's Ames-based reporter Amy Mayer and host Ben Kieffer discuss the future of ethanol in the U.S.
