Can sea salt expire?

Best Answers

Manufacturers harvest sea salt by creating shallow ponds that get lots of sun and wind, resulting in the evaporation of the water and concentration of the salt. This salt is formed into mounds and processed for purification. Sea salt is an all-natural product that is part of the earth and doesn't expire. Sea salt with additives can spoil, though. read more

Salt, like a lot of other spices, may have a best before date but does not have an expiration date. You may safely use table or sea salt for your flavoring needs and your body needs after a best before date has lapsed. Other types of salt like Rock, Pickling and Bath salts can also be used for extended amounts of time. read more

I suppose it depends on how the sea salt is stored. Sadly, humidity will eventually cause the salt crystals to crumble and turn to powder, but if probably preserved in a sealed glass container, your sea salt should last quite some time. In any event, a shelf life of one to two years is not unreasonable. read more
