Farms that raise turkeys and chickens for meat and eggs are on high alert, fearing a repeat of a widespread bird flu outbreak in 2015 that killed 50 million birds across 15 states and cost the federal government nearly $1 billion. The new fear is driven by the discovery announced Feb. 9, 2022, of the virus infecting a commercial turkey flock in Indiana and now Wisconsin. Charlie Neibergall/AP Photo
