How long does seaweed last?
The shelf life of seaweed can vary depending on the type of seaweed and how it is stored. Generally, fresh seaweed that has not been processed or cooked will last only a few days in the fridge, typically around 3-5 days.

To maximize the shelf life of dried seaweed, it should be kept in an airtight container in a cool, dry place away from direct sunlight. The shelf life of edible seaweed also varies greatly depending on its preparation. There are three common varieties: fresh seaweed, plain, dried seaweed, and dried and seasoned seaweed. These different varieties have different shelf lives. The storage method also affects how long seaweed lasts.
It's important to note that if you see any signs of spoilage, such as a slimy texture or unpleasant odor, you should not consume the seaweed, even if it has been stored properly. When in doubt, it's best to err on the side of caution and discard any seaweed that appears to be spoiled.
