A fifth case of bird flu has been identified in Ireland.

The latest bird to test positive for H5N8 is a whooper swan in Ballinturley, Roscommon.

It is the third swan to have been found to be infected with the virus – the other cases were on the Longford-Leitrim border and in Tipperary.

The other two cases occurred in a species of duck known as wigeons.

In December, the Department of Agriculture activated regulations requiring all poultry and captive birds to be kept within a secure building amid concerns over bird flu.

The public is advised not to handle dead or sick birds.
