How to Tell if Frozen Lobster is Bad

Frozen Lobster

There are many signs that frozen lobster is terrible, including ammonia odor and different colors. If you notice any of these, return them or throw them away. Eating spoiled lobster isn’t a good idea because it poses a health risk. Once it has thawed, you can smell its ammonia odor at room temperature. If the odor is faint, that’s not a problem.
