Minas Gerais, Brazil's largest milk producer, is ramping up brucellosis prevention by vaccinating calves aged 3 to 8 months. Led by the State Department of Agriculture, Livestock and Supply (Seapa) and the Minas Gerais Agricultural Institute (IMA), the campaign aims to protect public health and prevent economic losses. Livestock farmers have specific deadlines for vaccinating and declaring their calves' vaccination. Currently, 45.3% of eligible female cattle and buffaloes are immunized, with a target of 80%. The state also stresses the importance of consuming officially registered artisanal cheese for safety. Vaccination must be conducted by IMA-registered professionals due to the live vaccine's risks. Certification of brucellosis and tuberculosis-free properties offers benefits like better herd productivity and market access, with guidelines available on the IMA website.
