What is a common sign that seafood may not be safe to eat?

A strong smell is indeed a common sign that seafood may not be safe to eat. Fresh seafood should have a clean, mild scent similar to the ocean. An overpowering or off-putting odor is an indication that the seafood may be spoiled or beginning to deteriorate. This change in scent is often caused by the growth of bacteria or the breakdown of tissues, which can occur as seafood ages or is improperly stored.

In contrast, bright colors are typically a sign of freshness in seafood, solid texture indicates that the seafood is firm and not mushy, and clear appearance is generally desirable, suggesting that the seafood is free from contaminants and decay. Recognizing the strong smell as a red flag is crucial in ensuring food safety, especially with perishable items like seafood.
