This article will provide you with the knowledge you need to choose frozen tuna wisely, whether you’re a fan of sushi or you’re just wondering about the health effects of eating raw fish.

Is Frozen Tuna Safe To Eat Raw

Raw fish is typically thought to be safer when frozen. To ensure that tuna is safe to consume raw, the FDA advises freezing it for at least 15 hours at -4 °F (-20 °C).

Due to the slowed growth of germs and other microbes, freezing raw tuna can make it last longer and lower the chance of contracting a foodborne disease.

The thawing and cooking processes might also affect the quality of the frozen tuna.

Follow suggested freezing and thawing instructions for handling and storing frozen tuna in order to reduce these consequences.

Risks associated with eating raw frozen tuna

Eating raw, frozen tuna increases your chance of contracting a foodborne disease, especially from parasites like sushi-borne anisakiasis or bacteria like Vibrio or Salmonella.
