Vegetables and fruits consumed raw are important because of their high fiber and vitamin content. During harvesting, transportation, processing, and sales operations, such foods can be intensively contaminated with pathogenic and toxigenic microorganisms such as Salmonella ssp., Escherichia Coli 0157: H7, Staphylococcus Aureus, Listeria Monocytogenes, Yersinia spp. ye Campylobacter spp. When microorganisms (especially pathogens) and / or toxins that live on the surfaces of vegetables and the vegetable products and fruits are consumed, they pass directly on to people and cause important health problems. For this reason, surface decontamination processes applied to raw vegetables and fruits are gaining importance. In this study, the apples were washed with washing water in three different times (3 minutes, 6 minutes, 10 minutes). After washing the apple surface; the lethal effect on pathogens was investigated by applying an environmental 2100 MHz (3G) frequency in three different time periods (30 minutes, 1 hour, 2 hours, 4 hours).
