Salt does not expire in the traditional sense, as it does not support the growth of bacteria or mold. However, over time, salt can absorb moisture from the air and may clump together or harden. This can affect its texture and make it more difficult to use, but it does not mean that the salt has gone bad. Properly stored in a cool, dry place, salt can last indefinitely. **
