Salt has a shelf life, and it is not recommended to eat after it expires. The storage time of salt should not be too long, and the shelf life is generally 3-5 years, because iodine and potassium are generally added to salt. If exposed to the air for a long time, the content of iodine and potassium in salt will be insufficient.

Does salt have a shelf life? Can I eat it after it expires?

Because salt only contains pure sodium chloride, and sodium chloride is very stable, even if it is kept for a long time or wet, the salty taste will not change, so generally speaking, pure salt itself has no shelf life.

Salt has a good bactericidal and anti-inflammatory effect and has nothing to do with iodine. Expired salt can be used to soak feet, clean wounds, take a bath and so on.
