By examining the growth of Listeria monocytogenes in cabbage and radish salads, during 48 h, at 4 and 20 deg C, we determined that cabbage presents very convenient base for the growth of these bacteria. At 20 deg C, sweet basil added in 1%, 2.5% and 5% concentrations, were not so effective in preventing the growth of Listeria monocytogenes in cabbage salad. At the other hand, it was determined that the radish does not present a convenient media for Listeria monocytogenes growth, because of the presence of phitoncide, sulphuric compounds and spicy ingredients in this vegetable. Adding sweet basil causes decreasing the initial amount of Listeria monocytogenes which are at the highest concentration of 5% more that 1 log cycle for both examined temperatures. The influence of basil can be explained by the influence of essential oils and aromatic compounds, which are present in spice.
