What critical sign indicates previously frozen fish should not be purchased?
Answer
Fish that is actively thawing or has ice crystals mixed into the flesh
Handling previously frozen fish correctly during the thawing process is essential to maintaining quality. A major red flag is encountering fish that is still in the process of thawing or, crucially, fish that has ice crystals embedded within its muscle tissue. This indicates improper handling or insufficient temperature control. Fish that has been properly thawed should appear firm and moist, whereas fish that is watery or limp has likely deteriorated past its optimal state.
