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.
