Is Tuna Served Raw in Sushi?
Tuna is often served raw in sushi, but it depends on the type of sushi and the restaurant. In traditional sushi restaurants, tuna is typically served as sashimi, which is thinly sliced raw fish served without rice. However, some sushi restaurants may choose to sear or cook the tuna slightly before serving it.
It’s worth noting that even if the tuna is served raw, it’s usually frozen to a certain temperature to kill any parasites that may be present. This process is called “sashimi-grade” freezing, and it’s a common practice in the sushi industry to ensure food safety. So, while the tuna may be raw, it’s still safe to eat.
What Types of Tuna Are Typically Used in Sushi?
There are several types of tuna that are commonly used in sushi, including bluefin, yellowfin, and bigeye. Bluefin tuna is considered to be the highest quality and is often used in high-end sushi restaurants. Yellowfin tuna is also popular and is known for its rich flavor and firm texture.
Bigeye tuna is another type of tuna that’s often used in sushi, and it’s known for its rich flavor and high fat content. Some sushi restaurants may also use other types of tuna, such as albacore or skipjack, but these are less common. The type of tuna used can affect the flavor and texture of the sushi, so it’s worth trying different types to see which one you prefer.
Is Raw Tuna Safe to Eat?
Raw tuna can be safe to eat if it’s handled and prepared properly. As mentioned earlier, sashimi-grade freezing is a common practice in the sushi industry to kill any parasites that may be present. Additionally, sushi restaurants are required to follow strict food safety guidelines to minimize the risk of foodborne illness.
However, there are some risks associated with eating raw tuna, particularly for certain groups of people. Pregnant women, young children, and people with weakened immune systems may be more susceptible to foodborne illness and should avoid eating raw tuna. It’s always a good idea to check with your doctor or a trusted healthcare professional if you have any concerns.
Can I Get Food Poisoning from Eating Raw Tuna in Sushi?
Yes, it is possible to get food poisoning from eating raw tuna in sushi, although the risk is relatively low if the tuna is handled and prepared properly. The most common types of food poisoning associated with raw tuna are scombroid poisoning and ciguatera poisoning.
Scombroid poisoning is caused by a type of bacteria that can grow on fish that’s not stored properly. Ciguatera poisoning is caused by a toxin that’s produced by certain types of algae that can accumulate in fish. Both types of food poisoning can cause symptoms such as nausea, vomiting, and diarrhea, and can be treated with medication and rest.
How Do Sushi Restaurants Handle and Store Raw Tuna?
Sushi restaurants are required to follow strict guidelines for handling and storing raw tuna to minimize the risk of foodborne illness. This includes storing the tuna at a consistent refrigerated temperature, handling it gently to prevent damage, and using clean utensils and cutting boards.

The FDA recommends that pregnant women avoid eating raw or undercooked fish, including tuna, to minimize the risk of foodborne illness. Instead, pregnant women can opt for cooked tuna or other types of fish that are lower in mercury and other contaminants. It’s always a good idea to check with your doctor or a trusted healthcare professional for personalized advice.
How Can I Tell If the Raw Tuna in My Sushi Is Fresh?
There are several ways to tell if the raw tuna in your sushi is fresh. One way is to look for a pleasant smell – fresh tuna should have a mild, slightly sweet smell. You can also check the color and texture of the tuna – it should be a deep red color and have a firm, meaty texture.
Another way to tell if the tuna is fresh is to ask your server or the sushi chef. They can tell you when the tuna was delivered and how it’s been stored, and can also provide information about the type of tuna and where it was sourced. If you’re still unsure, you can always opt for cooked tuna or another type of fish instead.
