Avian flu detected in Canada goose in Vantaa

A case of avian influenza has been confirmed in a Canada goose found in Vantaa this month, the city announced on Wednesday.

The highly contagious virus can spread rapidly among birds and may cause mass die-offs, according to authorities. Residents are urged to report any unusual deaths of wild birds to local officials, who will arrange for testing.

A mass die-off is defined as more than five dead waterfowl or crows, or over ten other bird species, found in the same area. Even a single dead bird of prey or two deceased swans must be reported.

During office hours, reports can be made to Vantaa’s supervisory veterinarians at +358 40 1852674 or +358 40 5360337. Outside office hours, including evenings and weekends, residents should contact Vantaa’s small animal emergency service at +358 43 824 7475 or submit a report via the Finnish Food Authority’s online form.

Individual dead birds do not need to be reported but can be disposed of by placing them in a sealed bag with household waste, using gloves and a mask. Burial at a depth of at least 40 centimetres is also an option.

Protecting poultry and pet birds
The city reminds residents that during the outbreak, domestic poultry and pet birds must be shielded from contact with wild birds. Poultry must be kept indoors or in fully enclosed outdoor areas covered with sufficiently dense netting from 8 February to 31 May nationwide.

To prevent infection, bird feed and water must be protected from contamination by wild bird droppings. Outdoor cages can be covered with tarpaulin if necessary.

Owners should immediately contact a supervisory veterinarian—or the emergency service outside office hours—if their birds show symptoms of avian flu. These may include lethargy, loss of appetite, head swelling, respiratory issues, diarrhoea, neurological signs, reduced egg production, or sudden death.

The risk of transmission to humans remains low, authorities said.
