Based on the recommended use-by dates provided by Morton Salt, the duration salt should last varies depending on the type.
Salt itself does not technically "spoil" because it is a mineral that does not support microbial growth. However, some types of salt, especially those with additives or specific grinds, may have a recommended "used by" date. This date typically relates to maintaining optimal quality, texture, or the effectiveness of additives like iodine, rather than safety.
According to the Morton Salt Expiration Guide, here are the recommended durations:
| Product | Recommended Used By Date |
|---|---|
| Plain Table Salt, Coarse Sea Salt, Fine Sea Salt, Sea Salt, Grinders, Kosher Salt | 5 Years |
| Salt Substitute | 5 Years |
| Natural All Purpose Sea Salt, Canning & Pickling Salt, Himalayan Pink Salt | 3 Years |
These dates serve as a guideline for best quality. Proper storage in a cool, dry place helps maintain the salt's condition over time.
