This invention provides a food grade, GRAS disinfectant/sanitizer that can be applied to various food systems. Such disinfectant/sanitizer comprises an acidified antimicrobial nanoemulsion assembled spontaneously in the presence of an organic phase and an aqueous phase comprising an organic acid and an essential oil. The essential oil functions to permeabilize and depolarize the cytoplasmic membrane of foodborne pathogens while the organic acid has a direct impact on the intracellular pH of the pathogens. This combination has been proven to be effective with significant log reductions of various pathogens on both food and non-food surfaces. The utilization of spontaneous emulsification allows for minimal equipment, nominal training, and low energy by employing the stored chemical energy of the system.
