More than 5 million hens will be euthanized at an Iowa egg-laying facility after the majority of them were found to be contaminated with a lethal strain of avian influenza, or bird flu. It is the worst outbreak yet to be recorded in the US.
This is the second time a bird flu epidemic has been reported in Iowa, which provides almost 20 percent of all eggs that are consumed in the United States.
