Veterinary experts meeting in Paris say all countries regardless of their economic problems must fight bird flu.
The World Organization for Animal Health said Tuesday just one country failing to control bird flu can endanger the whole planet.
The experts warned that the deadly H5N1 virus is highly likely to infect domestic poultry in Europe as migrating wild birds return from Africa and the Mideast.
Bird flu has already struck a turkey farm in France. France says 43 countries have either banned or curbed exports of French poultry.
Meanwhile, Sweden reported its first bird flu case in wild ducks Tuesday.
And bird flu was found in a cat on the German Baltic Sea island of Ruegen, where bird flu killed a number of wild birds.
Experts say there is no evidence cats can spread the disease to humans.
Some information for this report was provided by AFP, AP and Reuters.
