The United States banned poultry imports from British Columbia on Monday after Canadian officials confirmed a single case of avian influenza in a duck on a farm there. Canadian officials stressed that the strain wasn't the deadly H5N1 strain that has devastated the poultry industries in several countries in southeast Asia.

Taiwan and Japan said they will also ban poultry imports from British Columbia.

The United States currently bans the importation of chicken from any country where the H5N1 strain has been confirmed, including Cambodia, Romania, China, Russia, Indonesia, South Korea, Japan, Thailand, Kazakhstan, Turkey, Laos, Vietnam, and Malaysia.

The Canadian Food Inspection Agency said Sunday that a duck at a commercial poultry farm in British Columbia had tested positive for avian influenza. The virus was a low-pathogenic North American form that doesn't kill poultry and is not a threat to people, officials said.

"We're waiting to get more information from Canada, at which point we could be able to scale back" the ban, USDA spokesman Jim Rogers said. "We just need that information." Canadian officials plan to report to the U.S. within 24 hours, according to Canada's chief veterinary officer, Dr. Brian Evans. Depending on the results, the U.S. could restrict imports from a smaller, regional area, Rogers said.
