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.
