A Long Island farm will reportedly euthanize more than 100,000 ducks after a bird flu outbreak transpired at the eastern New York facility.

The avian flu outbreak that has led to the slaughter of millions of birds at U.S. poultry farms and driven up the price of eggs struck the Crescent Duck Farm this week, leading federal officials to order the destruction of the operation’s entire flock.

As more cases of bird flu emerge across the country, public health leaders in New York City are watching warily -- and making preparations in case the virus becomes a more immediate threat.
