Belgian authorities found the H5N8 bird flu virus at a farm north of Brussels on February 1 and imposed measures to contain the spread of the highly contagious virus, the Belgian agriculture ministry says.
The virus was found at a site belonging to a bird enthusiast in the area of Lebbeke.
"The highly pathogenic character of this virus strain has yet to be confirmed," it said on Thursday, adding the authorities established a three kilometre sanitary perimeter around the site. It said there were no poultry farms in that area.
"The virus that has been severely affecting neighbouring countries for several months has now reached Belgium. At this stage, the professional sector is not affected, but we must remain very vigilant," Belgian Agriculture Minister Willy Borsus said in the statement.
"A strict application of bio-security measures is essential for this case to remain isolated," he said. The ministry added Belgian consumers were facing no risks.
