Q&A: Details about what's next in bird flu response efforts

More than 414,000 turkeys and chickens have been killed, some through a method considered a "last resort" of euthanasia, at 10 southwest Indiana farms affected by a bird flu outbreak. Testing and monitoring will continue for weeks to determine if the outbreak of the H7N8 viral strain is contained. That strain is different from one that led to the deaths of more than 48 million birds last summer.
