The Brazilian Ministry of Agriculture and Livestock has introduced the National Plan for Individual Identification of Cattle and Buffalo (PNIB). The initiative aims to enhance health security and efficiency in disease response by establishing an individual identification system for cattle and buffaloes. Over an eight-year period, the plan will be implemented, starting with the development of the system and gradually expanding traceability to all animals leaving rural properties. The use of electronic identification and the possibility of reducing trade embargoes in case of serious diseases are key benefits of the plan. The PNIB is voluntary and has support from the private sector, with the goal of making Brazil a global example in animal health and traceability.
