Popis: A water-assisted microwave treatment was studied against the pathogenic bacterium Salmonella Typhimurium in fresh jalapeno peppers and coriander foliage. Vegetables were immersed in water and treated in a microwave oven at 950 W to reach up 63 °C: jalapeno pepper for 25 s and coriander foliage for 10 s. After the microwave heating, samples were cooled in water at 4 °C. Samples were observed with confocal microscope before and after treatment. The proposed protocols resulted in a reduction of 4–5 log cycles on the Salmonella population, which is the main issue from the microbiological viewpoint. Even color of the vegetables was affected by the treatments ( p
