DAERA said in a statement this Friday that the decision was made in light of continuing findings of the highly pathogenic H5N8 avian influenza virus in Britain and in the Republic of Ireland. Cases were identified earlier this week in a wild swan in Co Tipperary and on a turkey farm in England.The restrictions were introduced for one month on 23 December across the island of Ireland. A separate decision is expected before the initial 30-day period expires on Monday in the Republic.
