Trade of infected poultry most likely bird flu route
A new study by British and American researchers says
that the H5N1 strain of bird flu is most likely to enter North America through
the trade of infected poultry.
They concluded that poultry trade was often the source, with migrating fowl
then spreading it further.
"We conclude that the most effective strategy to prevent H5N1 from being
introduced into the Western Hemisphere would be strict controls or a ban on the
importation of poultry and wild birds into the Americas and stronger enforcement
to curb illegal trade," they wrote.
Genetic testing allowed most of the H5N1 outbreaks to be traced to the
poultry trade, migratory birds or wild birds.
The findings point to the importance of surveillance programs for early
detection of bird diseases like H5N1, they said, noting that Canada, Mexico and
other countries import day-old chicks from other regions while the US does
Illegal trade in chicken feces for fertiliser and fish food could also be a
source of the disease.
