Brazil remains the 4th largest global producer and exporter of pig meat, despite the challenge of Classical Swine Fever (CSF) in northern and northeastern regions. This disease, while not harmful to humans or other animals, causes significant economic loss through high mortality rates and reproductive issues. Infection spreads through direct contact with the virus, leading to symptoms like fever, skin lesions, and diarrhea. Preventive measures include biosecurity, hygiene, and vaccination, with a national immunization campaign launched in 2021 in partnership with the private sector, including Zoetis, the only company producing the PSC vaccine. This campaign aims to control the disease and support the growth of the pig farming sector.
