Brazil reports first ever cases of avian flu
The H5N1 subtype of the influenza virus was found in two marine birds on the southeastern coast of Brazil.
Brazil’s first ever cases of Highly Pathogenic Avian Influenza (HPAI) have been confirmed by Brazil’s Agriculture Ministry on 15 May. The H5N1 subtype of the influenza virus was found in two marine birds on the coast of Brazil's southeastern state of Espirito Santo.
The government confirmed that epidemiological surveillance services will be increased in the nearby area, to detect any further cases of avian flu in wild and commercial animals.
The World Organisation for Animal Health (WOAH) does not recommend a ban on imports of Brazilian poultry products because the cases were found in wild animals.
Brazil is one of the world’s largest exporters of chicken, trading with countries such as China, Japan, South Africa and Saudi Arabia. Its chicken exports rose by 27 per cent in 2022 while other countries experienced outbreaks of avian flu.
Miguel Gularte, CEO of a large chicken exporting company in Brazil told a press conference that he was not surprised by the case of highly pathogenic avian influenza, adding the company was prepared for any scenario. He noted the company relies on Brazil’s "robust" animal health services to prevent and contain any potential threats to industrial poultry farms.
Brazil’s neighbouring country Argentina, recorded its first case of avian flu in its poultry industry in late February. It suspended exports until late March, when the area was confirmed as being free of avian flu.
