Infection was detected in a pallor-sea, wild bird found in central Diadema; state government states that if it is isolated, it does not pose a risk to the population and does not affect production or export
The São Paulo Secretariat of Agriculture and Supply confirmed the first case of in 2025. The infection was detected in a wooden seam, a wild bird found in central region in Greater São Paulo. According to the state government, the case is isolated, does not pose a risk to the population and does not affect the production or export of poultry and eggs. The diagnosis was confirmed by the Federal Agricultural Defense Laboratory (LFDA-SP).
The bird had clinical signs as difficulty in flying, lethargy and respiratory and neurological changes, and did not react to human presence. The Agricultural Defense Coordination (CDA) performed the collection of samples for examination. By 2025, São Paulo had already received 37 suspicious notifications of the disease, but this was the first case confirmed in the year. In 2024, there was only one focus. Already in 2023, there were 53 cases, all also in wild birds.
The first record of avian flu in commercial farms in Brazil took place on May 15 this year, in Montenegro (RS). Confirmation led about 20 countries, such as China, Mexico and South Africa, to temporarily suspend the importation of Brazilian chicken meat.
Because it is a wild bird, there is no change in the state or country’s health status to the World Animal Health Organization, and there is no impact on exports. The Secretariat of Agriculture stresses that the consumption of poultry and egg meat is safe. According to CDA, there are no commercial farms within 10 kilometers where the case was detected.
Teams will take surveillance actions in the region to identify any dead birds or with symptoms of the disease. Residents will be advised to communicate any suspicious sign. Agricultural defense maintains contact with the Secretariat of Health, Secretariat of the Environment, Zoos and NGOs for joint prevention actions.
Avian flu is not transmitted by the consumption of chicken meat or eggs. Human infection occurs mainly by direct contact with sick or dead birds. Therefore, the recommendation is not to touch birds with symptoms and, if necessary, use protective equipment such as gloves and masks. To date, there are no records of the disease in humans in the state.
The Secretariat of Agriculture has prepared a contingency plan to deal with possible cases in people, and is monitoring all those involved in the notification in Diadema. Suspected disease or dead birds should be communicated immediately to agricultural defense. Unit addresses are available at.
