The order requires market owners to sell or otherwise remove all live birds and conduct a thorough cleaning and disinfection of their facilities—even if bird flu wasn't detected there.

Multiple cases of bird flu in chickens are forcing the closure of live poultry markets in parts of New York state, Gov. Kathy Hochul, D-N.Y., announced Friday.
