Foodborne diseases (FD) are caused by consuming food and water previously contaminated by pathogenic microorganisms, Escherichia coli being the most frequent agent. For this reason, the food industry uses antimicrobial biocides such as sodium metasilicate (SM) to process ingredients in meat-based products, thus preventing the proliferation of E. coli in food. However, given the high demand for natural preservatives, essential oils from plants have been proposed as valid alternatives to serve as bio preservatives. These oils react with the lipids in the cell membranes of various bacteria, increasing the membrane's permeability and altering its original structure. For this reason, the objective of this study is to measure the interaction between oregano essential oil (OEO) and MS in the prevention of bacterial proliferation of Escherichia coli. To achieve this, control, individual, and interaction tests were performed using sodium metasilicate and oregano essential oil. Our control test indicated that the medium was optimal, no contamination and the solvent used did not alter the subsequent tests. Individual assays determined SM and OEO minimal inhibitory concentrations (MIC) of 0.096% and 0.09%, respectively. Likewise, the MIC of OEO in combination with SM and the MIC of SM in combination with OEO were determined, resulting in values of 0.008% and 0.01%, correspondingly. Finally, when calculating the fractional inhibitory concentration (FIC) index, it was determined that it was less than 0.5, which indicates that the combination of both compounds has a synergistic effect in inhibiting the growth of E. coli.
