Salt kills microbes. High salt can also be toxic to internal processes of microbes, affecting DNA and enzymes. Solutions high in sugar also have the same effects on microbes, which is why it is used as a preservative of foods, such as jams and jellies.
Can bacteria grow in salt?
One thing is for sure: there’s bacteria in that salt. In food preservation (e.g. meat curation), salt is used to control microbes. It prevents the growth of bad bacteria but allows others to grow. One teaspoon of salt can contain over 4000 bacterial cells.
What happens if you don’t eat salt for a week?
