However, table salt that has other chemicals added to it may go bad. The salt itself does not go bad, but the chemical may go bad. One example of these chemicals is iodine which is added to salt to prevent goiter, a thyroid disease. 

This is why table salt comes with the best before date. It still does not mean that the salt will be harmful if used. Instead the chemicals may just not provide the benefits that they were meant to provide.
