(Reuters) -An outbreak of bird flu in Brazil, the world's largest chicken exporter, prompted countries to implement trade restrictions in an effort to prevent the spread of the virus after a first case was confirmed 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 some importers have now reversed their bans.

The following is a list from Brazil's Agriculture Ministry of countries maintaining their bans as of July 23:

SUSPENSIONS TARGETING ALL POULTRY FROM BRAZIL

China, the European Union, Chile, Canada, Malaysia, East Timor, North Macedonia and Pakistan.
