Does seaweed salad go bad?

Yes, seaweed salad can go bad. Seaweed salad, when stored properly in the fridge, lasts for about 3-4 days after which it will start to go bad. Dried seaweed salad, on the other hand, can last for years since the removal of all the moisture makes it hard for bacteria or mold to spoil it. 

How to tell if seaweed salad has gone bad?

You can tell if seaweed salad has gone bad if it has a bad odor. You can also tell if it has gone by looking at its texture. Fresh seaweed salad will be crisp while spoiled seaweed will be limp and soggy, or slimy. 

How to properly store seaweed salad?

Seaweed salad should be kept in an airtight container or a ziplock bag then placed in the fridge to maintain its freshness. Do not leave it out at room temperature, keep it at cooler temperatures so that it does not go bad quickly.

You can also keep it in the freezer if you want it to last for a couple of months.

Does dried seaweed go bad?

No, dried seaweed does not go bad because it has all of its moisture removed so it can not grow mold or bacteria on it. However, it may lose its taste over time but it will most likely remain safe to eat.

Seaweed usually comes with a best before date label on its packaging. If you do see this label, then it simply means the amount of time seaweed will stay in its best quality and retain its flavor and freshness. After this time, the seaweed will be safe to eat when stored properly however it may not have the same taste and freshness.

Fresh seaweed lasts for about 3-4 days in the fridge after which it starts to go bad and loses its texture.

How to store dried seaweed?

Dried seaweed can be kept in a cool, dry place in the pantry in its original packaging when unopened. Once opened, you should seal the packaging back again. Dried seaweed should not be exposed to moisture as it can absorb it and lose its texture. 

So, if it did not come in a resealable packaging, then transfer it to an airtight container or a ziplock bag then place it in the pantry. You can also use silica gel to absorb excess moisture from around it. 

You should not refrigerate dried seaweed. This is because there is a lot of humidity inside the fridge so this will lead to textural changes in the seaweed and may also make it prone to mold. If you do choose to put it inside the fridge, make sure it is placed inside a ziplock bag or an airtight container so that no moisture comes in contact with it.

How to tell if dried seaweed has gone bad?

You can tell if nori (dried seaweed) has gone bad by looking at its color. If you see any discolorations, it probably has gone bad. It should be greenish-black in color. 

If nori gets wet or absorbs moisture, then it can get soggy, mushy or even sticky. You can not use this kind of seaweed so you should throw it away.

Next, wet seaweed is also prone to mold so if you see any moldy spots on it, then toss it out at once since you can not eat it. 

If you notice a bad odor, or an off smell then it is a sign that it has gone bad.

If all else looks fine, then taste some of it and see if it tastes fine. Most often, old seaweed will be okay to eat except it may lack some flavor.
