NEW YORK — All live poultry markets in New York City and some of its suburbs were ordered Friday to close for a week after the detection of seven cases of avian flu, which has also hit farms nationwide, led to the slaughter of millions of birds and driven up egg prices.

Gov. Kathy Hochul said there is no immediate threat to public health and that the temporary closing of bird markets in the city and its Westchester County and Long Island suburbs comes out of an abundance of caution. No cases of avian flu have been detected among humans in New York, officials said.

More than 156 million birds nationwide have been affected by the outbreak, many at large farming operations that have had to slaughter entire flocks. — Associated Press
