Question: 1 / 400

What should you do to prevent parasites in fish intended to be consumed raw?

Marinate the fish before eating

Freeze fish at -4 degrees F for at least 7 days

Freezing fish at -4 degrees Fahrenheit for at least 7 days is an effective method to eliminate parasites that can be harmful to human health when consuming raw or undercooked fish. This temperature and duration are guidelines established to ensure that parasites, such as Anisakis and other potentially harmful organisms, are killed, making the fish safe for consumption.

While marinating or rinsing the fish in vinegar might alter its flavor or texture, these methods do not reliably kill parasites. Cooking the fish until fully done is certainly a safe practice but does not apply to raw consumption. Thus, freezing fish is the most reliable and effective preventive measure specifically for raw fish consumption.
