Opening up the debate a bit, why do we have to transport birds thousands of miles in the first place. These birds are kept in very crowded conditions for days and half of them die on route.
I am all for banning importing wild birds because its cruel, and if it stops the spread of bird flu then even better.
There were two flu pendemics(?sp) last century, one in 1918 which killed more people than the first world war, and the other was in the 1950s, apparently these things tend to happen every 50 years or so.
I will worry when and if it mutants.
