SAO PAULO - Brazil, the world's largest chicken exporter, has ruled out three of seven suspected cases of highly pathogenic avian influenza, commonly known as bird flu, officials said at a press conference on May 19, citing laboratory test results.

The government had been investigating seven cases after the first outbreak was confirmed on a commercial farm in Brazil last week, according to updated information on the Agriculture Ministry's website.

Two of the cases still under investigation concern poultry raised on commercial farms and five involved backyard flocks in Brazil, which sold some US$10 billion (S$13 billion) worth of chicken products globally in 2024, supplying more than five million tonnes.

All three negative tests related to samples taken from subsistence, non-commercial farms, officials said.
