May 24 (Reuters) - The U.S. has imposed import curbs on certain poultry and byproducts from Victoria, Australia after determining highly pathogenic avian influenza, or bird flu, in domestic birds.
The Department of Agriculture's Animal and Plant Health Inspection Service said on Friday the restrictions from May 22 will continue until further notice.
Unprocessed avian products and byproducts originating from or transiting the State of Victoria will not be permitted to enter the United States, the U.S. department said.
Imports of poultry, commercial birds, ratites and hatching eggs have also been prohibited. Pet and zoo birds may be imported under an import permit, subject to a 30-day quarantine.
The avian influenza has spread to humans and other mammal species, including among U.S. dairy cattle in March, raising concerns of it mutating into a virus that is transmissible between humans and sparking a pandemic.
Victoria was also the site of an H7N7 outbreak in 2020, the most recent of Australia's nine outbreaks of bird flu since 1976. All were quickly reined in and stamped out, according to Australia's government.
