Extremely Low Frequency Magnetic Field (ELF-MF) is non-ionizing radiation with the process uses magnetic field, through methods of ELF-MF can prevent food from contamination of Salmonella Typhimurium. The purpose of the research was to determine the intensity of the radiation dose and exposure time ELF magnetic fields appropriate to the prevalence of Salmonella Typhimurium in food sample (gado-gado seasoning). Sample were treated using magnetic field with different intensities and times. The result showed that the pH measurement on sample no change significantly. Percentage of the deaths of Salmonella Typhimurium were higher up to 36.37% by ELF treatment with intensity 646.7µT for 30 minutes, and can be contracted the length and diameter of the cell of Salmonella Typhimurium. It can be concluded that the radiation ELF-MF is able to inhibite growth of pathogenic bacteria Salmonella Typhimurium.
