H5N1 may halt European movement to free-range poultry-raising
From ANIMAL PEOPLE, March 2006:
LONDON–The Tower of London ravens will be indoor cage birds
until the H5N1 crisis subsides, says raven keeper Derrick Coyle.
Legend has it that if the ravens ever leave the Tower, the
British monarchy will fall–and keeping the ravens indoors sets an
example for poultry farmers.
Just as animal welfare concerns made “free range” a household
phrase and free range poultry growing began to take market share from
intensive confinement, H5N1 might kill the whole concept.
“In the protection zone,” to be established around all H5N1
outbreaks within the European Union, the European Commission decreed
on February 12, 2006, “poultry must be kept indoors.”
Agreed United Nations Food & Agricultural Organization senior
officer of animal production and health Juan Lubroth, “People need
to ensure that poultry are roofed-in to avoid contact with wild
birds, and should not mix chickens with other species, such as
ducks,” since H5N1 is most likely to mutate into forms that can
easily spread when it has the opportunity to move from one species to
another.
