Tuna steak, a delicacy for many seafood lovers, is often served seared or grilled to perfection. However, some adventurous eaters may wonder: how raw can you eat tuna steak? The answer lies in the type of tuna, its freshness, and the risk of foodborne illnesses. In this article, we’ll delve into the world of raw tuna and explore the possibilities.
Understanding the Risks of Raw Tuna
Raw tuna can pose a risk of foodborne illnesses, particularly sashimi-grade tuna. The main concerns are:
Parasites and Worms
Raw tuna can contain parasites like Anisakis, a type of roundworm that can cause anisakiasis. This condition can lead to symptoms like nausea, vomiting, and abdominal pain. While the risk is relatively low, it’s essential to take precautions when consuming raw tuna.
Bacterial Contamination
Raw tuna can also be contaminated with bacteria like Salmonella and Vibrio vulnificus. These bacteria can cause food poisoning, which can be severe in people with weakened immune systems.
Types of Tuna: Which Ones Can Be Eaten Raw?
Not all tuna species are suitable for raw consumption. Some types of tuna are more prone to parasites and bacterial contamination than others. Here are some common types of tuna and their suitability for raw consumption:
Bluefin Tuna
Bluefin tuna is considered one of the safest types of tuna for raw consumption. It’s often used in high-end sushi restaurants and is prized for its rich flavor and firm texture.
Yellowfin Tuna
Yellowfin tuna is another popular choice for raw consumption. It’s slightly leaner than bluefin tuna but still packed with flavor.
Bigeye Tuna
Bigeye tuna is a type of tuna that’s often used in sashimi and sushi. It’s relatively safe for raw consumption, but it’s essential to ensure it’s sashimi-grade and handled properly.
What is Sashimi-Grade Tuna?
Sashimi-grade tuna is a term used to describe tuna that’s safe for raw consumption. To be considered sashimi-grade, tuna must meet specific criteria:
Freezing
Sashimi-grade tuna must be frozen to a certain temperature to kill parasites. The FDA recommends freezing tuna to -4°F (-20°C) for at least 7 days or -31°F (-35°C) for at least 15 hours.
Handling and Storage
Sashimi-grade tuna must be handled and stored properly to prevent contamination. This includes storing tuna at a consistent refrigerated temperature below 40°F (4°C) and handling it with clean utensils and cutting boards.
How to Prepare Raw Tuna Steak
If you’re looking to try raw tuna steak, here are some tips for preparation:
Choosing the Right Cut
Look for a cut of tuna that’s specifically labeled as “sashimi-grade” or “sushi-grade.” This ensures that the tuna has been handled and stored properly.
Freezing and Thawing
If you’re not using sashimi-grade tuna, you can freeze it to the recommended temperature to kill parasites. Once frozen, thaw the tuna in the refrigerator or under cold running water.
Slicing and Serving
Slice the tuna into thin pieces and serve it immediately. You can serve it on its own or with a variety of condiments and seasonings.

What is the risk of eating raw tuna steak?
Eating raw tuna steak can pose a risk of foodborne illness due to the presence of parasites such as Anisakis, which can cause anisakiasis. This risk is higher for certain groups of people, including the elderly, pregnant women, and those with weakened immune systems. It is essential to handle and store tuna steak properly to minimize the risk of contamination.
To reduce the risk of foodborne illness, it is recommended to freeze tuna steak at a temperature of -4°F (-20°C) for a certain period, which can kill parasites. Additionally, choosing sashimi-grade tuna steak from reputable sources can also minimize the risk. However, even with proper handling and storage, there is still a risk of foodborne illness associated with eating raw tuna steak.
How can I tell if my tuna steak is sashimi-grade?
Sashimi-grade tuna steak is typically labeled as such by the supplier or retailer. However, you can also look for certain characteristics to determine if your tuna steak is suitable for raw consumption. Sashimi-grade tuna steak should have a rich, meaty color and a firm texture. It should also have a pleasant smell and be free of any visible signs of spoilage.
When purchasing tuna steak, it is essential to buy from a reputable source, such as a high-end grocery store or a sushi restaurant. You can also ask the supplier or retailer about the origin and handling of the tuna steak to ensure it meets your standards. Keep in mind that even if your tuna steak is labeled as sashimi-grade, there is still a risk of foodborne illness associated with eating raw tuna steak.
Can I eat raw tuna steak if I’m pregnant?
It is generally not recommended to eat raw tuna steak during pregnancy due to the risk of foodborne illness. Pregnant women are more susceptible to foodborne illness, and the risk of anisakiasis is higher for this group. Anisakiasis can cause symptoms such as nausea, vomiting, and abdominal pain, which can be severe in pregnant women.
If you are pregnant and craving raw tuna steak, it is recommended to choose cooked tuna steak instead. Cooking tuna steak can kill parasites and reduce the risk of foodborne illness. Alternatively, you can also consider other types of fish that are lower in mercury and parasites, such as salmon or tilapia.
How do I store raw tuna steak to minimize the risk of contamination?
To minimize the risk of contamination, it is essential to store raw tuna steak properly. Raw tuna steak should be stored in a sealed container at a temperature of 32°F (0°C) or below. It is also recommended to store raw tuna steak on the bottom shelf of the refrigerator to prevent cross-contamination with other foods.
When storing raw tuna steak, it is also essential to handle it safely. Always wash your hands before and after handling raw tuna steak, and make sure to clean any utensils and cutting boards that come into contact with the fish. Additionally, it is recommended to consume raw tuna steak within a day or two of purchase to minimize the risk of spoilage.
Can I freeze raw tuna steak to kill parasites?
Yes, freezing raw tuna steak can kill parasites such as Anisakis. However, it is essential to freeze the tuna steak at a temperature of -4°F (-20°C) for a certain period, typically 7 days or longer. Freezing at a higher temperature or for a shorter period may not be sufficient to kill parasites.
When freezing raw tuna steak, it is also essential to handle it safely. Always wrap the tuna steak tightly in plastic wrap or aluminum foil to prevent freezer burn and contamination. Additionally, it is recommended to label the frozen tuna steak with the date and contents to ensure you consume it within a safe timeframe.
What are the symptoms of anisakiasis?
The symptoms of anisakiasis can vary depending on the severity of the infection. Common symptoms include nausea, vomiting, abdominal pain, and diarrhea. In severe cases, anisakiasis can cause intestinal blockage, which can lead to severe abdominal pain, vomiting, and constipation.
If you suspect you have anisakiasis, it is essential to seek medical attention immediately. Your doctor may perform a physical examination, take a medical history, and order diagnostic tests such as a stool test or endoscopy to confirm the diagnosis. Treatment for anisakiasis typically involves medication to kill the parasites and relieve symptoms.
Can I eat raw tuna steak if I have a weakened immune system?
It is generally not recommended to eat raw tuna steak if you have a weakened immune system due to the risk of foodborne illness. People with weakened immune systems, such as those with HIV/AIDS or undergoing chemotherapy, are more susceptible to foodborne illness and may experience more severe symptoms.
If you have a weakened immune system and are craving raw tuna steak, it is recommended to choose cooked tuna steak instead. Cooking tuna steak can kill parasites and reduce the risk of foodborne illness. Alternatively, you can also consider other types of fish that are lower in mercury and parasites, such as salmon or tilapia.
