New research has unveiled that your sushi may not be as fresh or authentic as you think.

Scientists warn that popular seafood like tuna, salmon, and prawns are often swapped for cheaper, mislabeled alternatives.

Common frauds include tuna being replaced with escolar, salmon with rainbow trout, and red snapper with tilapia.

This practice not only misleads consumers but also contributes to overfishing and threatens endangered species.

To avoid being duped, buy fish from trusted sources, ask about its origin, and opt for whole fish when possible.
