New York state has temporarily closed all live poultry markets in New York City and three suburban counties due to bird flu detected at seven markets. The virus has resulted in the death of over 156 million chickens, turkeys, and other birds nationwide since 2022, leading to a decrease in egg supply and a surge in prices. The closure is to allow markets to be cleaned and disinfected. The U.S. Department of Agriculture has confirmed a second strain of bird flu in U.S. dairy cattle, raising concerns about its spread.
