How Can You Tell If Seaweed Has Gone Bad?
Seaweed can go bad if it starts to smell unpleasant, becomes slimy or discolored, or develops mold or other growths. If the seaweed has a strong ammonia-like odor or looks brown or gray, it is likely spoiled and should be discarded. Additionally, softened or mushy texture can indicate the seaweed has gone bad. It is always best to use fresh seaweed when possible to avoid these issues.
