How to Tell If Yellowfin Tuna is Bad?

If you want to spot that your yellowfin tuna has gone bad, look for any discolored streaks in the meat. The discoloration should be dark brown or even black in the worst cases.

If the yellowfin tuna has all these discolorations and does not retain any of its reddish color, you shouldn’t consume the yellowfin. When yellowfin tuna is caught, it tends to turn brown naturally.

The seafood industry uses carbon monoxide to retain the pinkish and reddish hue of the tuna artificially.

However, if your yellowfin tuna is brown but still has its reddish tinge, it’s safe for consumption.

If the tuna turns dark evenly it doesn’t mean the tuna is bad, it means the meat is exposed to air, oxidizes and turns gray or dark.

Slice the meat and see if the inside is still pink. If the inside is pink the meat is good to eat. It means the meat hasn’t been exposed to oxygen yet.

Moreover, discoloration isn’t the only to tell if your yellowfin tuna has gone bad. Look for any overly fishy smell coming from the meat.

The smell can also be sour, and the meat can look dull in color with a slimy texture. Such tuna should be avoided to avoid the risk of contracting an infection.
