The objective of the study was; to determine the antimicrobial activity of extracts of Baccharis latifolia (Bl) against Salmonella, E. coli and Listeria of food origin; as well as evaluate the antioxidant activity of these extracts. Extracts of leaves, root, stem and Bl flowers were used. After the analysis of antimicrobial activity against Listeria and Salmonella. After analysis showed that leaf and flower extracts were more effective, while against E. coli, flower and stem extracts. In antioxidant activity, the Bl flower extract at 60 mg/mL had a greater effect with 47.25%. In conclusion, Bl extracts, proved to be a natural alternative to partially inhibit pathogen development
