Agricultural authorities in the Brazilian states of Mato Grosso, São Paulo, and Rondônia have initiated mandatory livestock declaration campaigns to support sanitary surveillance and disease control.

In Mato Grosso, the campaign runs from November 1 to December 10. Producers of various species, including cattle, buffalo, sheep, goats, horses, swine, poultry, fish, and bees, must report detailed animal and property data to the Institute of Agricultural Defense of the State of Mato Grosso (Indea). Failure to update data by November 9 will prohibit certain producers from issuing Animal Transit Guides (GTA), except for animals destined for slaughter. Non-compliance by the final deadline may result in fines.

In São Paulo, the declaration period runs from November 1 to November 30. Producers must use the Gedave system to report all species, such as cattle, buffalo, equines, swine, sheep, goats, poultry, fish, and beehives. This requirement follows the cessation of foot-and-mouth disease vaccinations in the state. Similar to Mato Grosso, the issuance of Animal Transit Guides for cattle and buffalo will be blocked until updates are completed.

In Rondônia, the update is managed by Idaron. Producers are required to report births, deaths, and age groups for cattle, swine, and poultry. This registration process is considered critical for maintaining Rondônia’s status as a foot-and-mouth disease-free zone without vaccination, a designation intended to facilitate access to international markets.
