(Reuters) -An outbreak of bird flu in Brazil, the world's largest chicken exporter, has prompted countries to implement trade restrictions in an effort to prevent the spread of the virus after Brazil confirmed its first case on a commercial farm in May.

Brazil declared itself free of the virus in commercial flocks after 28 days without any new outbreaks on commercial farms, and hopes importers will soon reverse those bans.

The following is a list from Brazil's Agriculture Ministry of countries that maintain their bans as of July 11:
