Brazil has opposed vaccinating for avian influenza over concerns that it would encourage trade barriers. Eduardo Cunha told the general session of WOAH in Paris, that if they are to vaccinate, it is likely that they would be subject to trade barriers. Brazil has thus far detected eight cases of AI in wild birds but its commercial flock remain safe. “Brazil exports poultry and poultry products to more than 130 countries. Negotiations with importers to accept vaccinated products would pose a challenge,” added Mr Cunha.
