The Danish authorities have confirmed several outbreaks of Newcastle Disease in poultry and have put restrictions in place, including controls on meat and meat products and a voluntary ban on exports of live poultry.  Newcastle Disease is a highly contagious disease, although flocks can be protected from the disease by vaccination, which affects fowls, turkeys, geese, ducks, pheasants, guinea fowl and other wild and captive birds, including ratities (flightless birds) such as ostriches, emus and rhea.
