Raw tuna has become a staple in many cuisines, particularly in sushi and sashimi dishes. However, not all tuna is created equal, and some types are better suited for raw consumption than others. In this article, we will delve into the world of tuna and explore the best types to eat raw, as well as the factors that determine their quality and safety.
Understanding Tuna: A Brief Overview
Tuna is a type of saltwater fish that belongs to the tribe Thunnini. There are 15 species of tuna, but only a few are commonly consumed. Tuna is a popular choice for raw consumption due to its meaty texture and rich flavor. However, tuna can also pose health risks if not handled and stored properly.
Tuna Species: A Breakdown
There are several species of tuna, each with its unique characteristics and flavor profiles. Here are some of the most common species:
- Bluefin tuna: Considered the king of tuna, bluefin is prized for its rich flavor and firm texture. However, it is also one of the most expensive and endangered species.
- Yellowfin tuna: Also known as ahi, yellowfin is a popular choice for sashimi and sushi. It has a mild flavor and a firm texture.
- Bigeye tuna: Similar to yellowfin, bigeye tuna has a rich flavor and a firm texture. It is also a popular choice for raw consumption.
- Albacore tuna: Also known as white tuna, albacore has a mild flavor and a soft texture. It is often used in canned tuna products.
Factors to Consider When Choosing Raw Tuna
When choosing raw tuna, there are several factors to consider to ensure quality and safety. Here are some of the key factors:
Mercury Levels
Mercury is a toxic substance that can accumulate in tuna and pose health risks to humans. Mercury levels vary depending on the species, size, and location of the tuna. Generally, smaller tuna have lower mercury levels than larger ones.
- Bluefin tuna: High mercury levels
- Yellowfin tuna: Moderate mercury levels
- Bigeye tuna: Moderate mercury levels
- Albacore tuna: Low mercury levels
Sashimi-Grade Tuna
Sashimi-grade tuna is a term used to describe tuna that is safe for raw consumption. To be considered sashimi-grade, tuna must meet certain criteria, including:
- Caught in a sustainable and responsible manner
- Handled and stored properly to prevent contamination
- Frozen to a certain temperature to kill parasites
- Inspected for quality and purity
Certifications and Labels
There are several certifications and labels that can help you identify high-quality and sustainable tuna. Some of the most common certifications include:
- MSC (Marine Stewardship Council) certification: Ensures that the tuna was caught in a sustainable and responsible manner.
- ASC (Aquaculture Stewardship Council) certification: Ensures that the tuna was farmed in a responsible and sustainable manner.
- “Sashimi-grade” label: Ensures that the tuna meets certain criteria for raw consumption.
The Best Tuna to Eat Raw
Based on the factors mentioned above, here are some of the best tuna to eat raw:
Yellowfin Tuna (Ahi)
Yellowfin tuna is a popular choice for sashimi and sushi due to its mild flavor and firm texture. It has moderate mercury levels, but it is generally considered safe for raw consumption.
Bigeye Tuna
Bigeye tuna is similar to yellowfin tuna in terms of flavor and texture. It also has moderate mercury levels, but it is considered a more sustainable choice than bluefin tuna.
Albacore Tuna (White Tuna)
Albacore tuna has a mild flavor and a soft texture, making it a popular choice for raw consumption. It has low mercury levels, making it a safer choice than other species.
How to Handle and Store Raw Tuna

What types of tuna are safe to eat raw?
When it comes to eating tuna raw, it’s essential to choose a type that is safe for consumption. Look for tuna species that are known to have low mercury levels, such as skipjack, albacore, and yellowfin. These types of tuna are generally considered safe to eat raw, but it’s crucial to ensure they are sashimi-grade and handled properly to minimize the risk of foodborne illness.
It’s also important to note that some types of tuna, such as bluefin and bigeye, have higher mercury levels and are not recommended for raw consumption. Additionally, tuna that is not sashimi-grade or has been previously frozen may not be safe to eat raw. Always check with the supplier or fishmonger to ensure the tuna you choose is safe for raw consumption.
What is sashimi-grade tuna, and why is it important?
Sashimi-grade tuna refers to tuna that has been caught, handled, and stored in a way that minimizes the risk of contamination and foodborne illness. This type of tuna is typically frozen to a certain temperature to kill any parasites that may be present, and then thawed and handled in a way that prevents cross-contamination.
Choosing sashimi-grade tuna is crucial when eating tuna raw, as it ensures that the fish is safe to consume. Sashimi-grade tuna is typically labeled as such by the supplier or fishmonger, and it’s essential to look for this label when purchasing tuna for raw consumption. If you’re unsure whether the tuna is sashimi-grade, it’s best to err on the side of caution and choose a different type of fish.
How do I handle and store raw tuna to prevent foodborne illness?
When handling and storing raw tuna, it’s essential to follow proper food safety guidelines to prevent foodborne illness. Always handle the tuna with clean hands and utensils, and make sure to store it in a sealed container at a temperature below 40°F (4°C). It’s also important to keep the tuna away from other foods and surfaces to prevent cross-contamination.
When storing raw tuna, it’s best to use a container that is specifically designed for storing raw fish. These containers typically have a tight-fitting lid and are made of a material that can withstand cold temperatures. Always label the container with the date and contents, and make sure to use the tuna within a day or two of purchase.
Can I eat raw tuna if I’m pregnant or have a weakened immune system?
If you’re pregnant or have a weakened immune system, it’s generally recommended to avoid eating raw tuna. Raw tuna can pose a risk of foodborne illness, particularly for individuals with compromised immune systems. Pregnant women, in particular, should avoid eating raw tuna due to the risk of mercury exposure, which can harm the developing fetus.
However, if you’re pregnant or have a weakened immune system and still want to eat tuna, it’s best to choose cooked tuna instead. Cooking tuna can help kill any bacteria or parasites that may be present, making it a safer option. Always consult with a healthcare professional or registered dietitian for personalized advice on eating tuna during pregnancy or with a weakened immune system.
How can I tell if raw tuna is fresh and of good quality?
When purchasing raw tuna, it’s essential to look for signs of freshness and good quality. Fresh tuna should have a pleasant ocean-like smell, firm texture, and a glossy appearance. Avoid tuna that has a strong fishy smell, soft texture, or dull appearance, as these can be signs of spoilage.
Additionally, look for tuna that has been stored properly and handled with care. Check the packaging for any signs of damage or leakage, and make sure the tuna is stored at a consistent refrigerated temperature. Always ask the supplier or fishmonger about the origin and handling of the tuna to ensure it meets your standards.
Can I freeze raw tuna to make it safe for consumption?
Freezing raw tuna can help kill any parasites that may be present, making it safer for consumption. However, it’s essential to freeze the tuna to a certain temperature (-4°F (-20°C) for a certain period (usually 7 days) to ensure that all parasites are killed.
It’s also important to note that freezing raw tuna does not eliminate the risk of foodborne illness entirely. Proper handling and storage of the tuna before and after freezing are still crucial to prevent contamination. Always follow proper food safety guidelines when freezing and thawing raw tuna.
Are there any health benefits to eating raw tuna?
Eating raw tuna can provide several health benefits, particularly due to its high protein and omega-3 fatty acid content. Raw tuna is an excellent source of protein, which can help support muscle growth and repair. The omega-3 fatty acids present in raw tuna can also help reduce inflammation and improve heart health.
Additionally, raw tuna is low in calories and rich in various vitamins and minerals, making it a nutritious addition to a balanced diet. However, it’s essential to consume raw tuna in moderation due to the risk of mercury exposure and foodborne illness. Always choose sashimi-grade tuna and follow proper food safety guidelines to minimize these risks.
