THE
United Nation’s food agency, the Food and Agriculture
Organization (FAO), is urging “absolute transparency
about disease outbreaks” among states and vigilance
among farmers if bird-flu control campaigns are to
succeed.
FAO made
the call after it expressed concern about new cases of
avian influenza (AI) detected in
China,
Egypt, Indonesia, Japan, Nigeria, South Korea, Thailand
and Vietnam.
The UN
agency, however, said the number of outbreaks in the
first weeks of 2007 has been significantly lower than
the epidemic waves of last year.
“Recent
outbreaks are following a seasonal pattern and do not
come as a great surprise. But we need to remain on the
alert as the recent outbreaks show. It is crucial that
countries themselves step up their surveillance,
detection and rapid response measures,” said Juan
Lubroth, senior officer of the FAO Animal Health
Service.
FAO
noted that it seemed that the intercontinental spread of
the H5N1 virus by wild birds migrating from Asia to
Europe and Africa had not taken place during this
autumn/winter season at the same level as it had in
2005.
The UN
agency, however, said poultry trade and the transport of
live birds could still spread the virus.
“Cold
weather enhances virus survival, but farming systems and
wild bird migration as well as the movement of animals
during important holiday seasons also play a role,”
noted FAO.
The UN
agency said absolute transparency about disease
outbreaks, involving farmers directly in surveillance
and reporting activities and establishing compensation
schemes are key to making bird-flu control campaigns
successful.
“Only
immediate reporting of any suspected bird-flu outbreak
makes possible rapid intervention by farmers and
veterinarians,” said Lubroth. “Unfortunately, many
outbreaks remain unreported. National and international
bodies are often not in a position to immediately verify
rumors or reports about unconfirmed
outbreaks.”
FAO
warned that the banning of backyard poultry or duck
raising could lead to illegal poultry production.
“Implementing and controlling these bans will be very
difficult to achieve. For economic reasons farmers will
tend to hide their animals and will not participate in
vaccination or movement controls,” said the FAO
official.
Instead
of banning production, FAO said, farmers should be
encouraged to participate in virus control and
vaccination campaigns.
In view
of the widespread virus distribution in Indonesia, FAO
has suggested that in addition to ongoing control
measures, day-old chicks should be vaccinated before
they leave their hatcheries and distributed, as well as
blanket vaccination in heavily infected districts. |
