 USDA's response to bird flu in poultry and cows will end up costing at least $2 billion, according to the Animal and Plant Health Inspection Service. APHA says it's committed about $1.3 billion so far, including $901 million to cover depopulation of poultry and eggs and $239 million on bird disposal. It also includes $163 million to address the recent outbreaks in dairy cows. Another $816 million is available to continue addressing bird flu.
