Abstract: Family farming is part of the economic base of 90% of Brazilian municipalities with up to 20,000 inhabitants, representing 40% of the country's economically active population. Milk production is a key component of this activity. Milk production is essential for human nutrition, and milk production is of great importance to family farming. This study evaluated 272 female cattle from 20 family farms located in the municipalities of Botucatu (2) (10%), Bofete (14) (70%), Pardinho (2) (10%), and Torrinha (2) (10%), in the state of São Paulo. The number of samples varied according to the animals available on the farms. Blood was collected from all animals, and the seroprevalence of leptospirosis in each herd was assessed using the Microscopic Serum Agglutination Test (SAM). The seroprevalence was 16.5% and the serovars found were: Hardjo prajitino (43%), Wolffi (19%), Hardjo CTG (8.9%), Hardjo bovis (3.8%), Guaricura (7.6%), Grippotyphosa (8.9%), Tarassovi (5.1%), Copenhageni (2.5%), and Canícola (1.3%). It is concluded that there is dispersion of different serovars in the evaluated properties, mainly with the participation of serovars adapted to wild species and not adapted to cattle (incidental), with possible elimination of leptospires and environmental contamination and risks of transmission to other animals and humans.
