Reuters recently reported that Iowa, the top U.S. egg-producing state, found a lethal strain of bird flu in millions of hens at an egg-laying facility earlier this week. This is the worst case so far in a national outbreak that prompted Wisconsin to declare a state of emergency. The infected Iowa birds were being raised near the city of Harris by Sunrise Farms in a facility that houses 3.8 million hens.
