AB [EN] The outbreaks of Listeria associated with food consumption are increasing worldwideconcurrently with public concern about the need for natural growth inhibitors. In this context,propolis seems to be a promising bioactive product collected by honeybees, due to its antimicrobialactivity against different food pathogens. This study aims to evaluate the efficacy of hydroalcoholicpropolis extracts for controlling Listeria under several pH conditions. The physicochemical properties(wax, resins, ashes, impurities), the bioactive compounds (phenolic and flavonoid content), and theantimicrobial activity of 31 propolis samples collected from the half North of Spain were determined.Results showed similar trends in the physicochemical composition and bioactive properties, regardlessof the harvesting area. Non-limiting pH conditions (7.04, 6.01, 5.01) in 11 Listeria strains (5 fromcollection and 6 wild strains from meat products) exhibited MICs (Minimum inhibition concentration)and MBCs (Minimum bactericidal concentration) ranging from 39.09 to 625  g/mL. The antibacterialactivity increased under acidic pH conditions, showing a synergistic effect at pH = 5.01 (p < 0.05).These findings suggest the potential of Spanish propolis as a natural antibacterial inhibitor to controlListeria growth in food products.
