Raw Ahi Tuna: Sashimi, Poke & Tartare Guide
Raw Ahi Tuna: Choosing, Handling and Serving Yellowfin for Sashimi, Poke and Tartare
By Oleg Nikitenko, Global Seafoods | Updated September 2026
“Ahi” commonly refers to yellowfin or bigeye tuna. This guide focuses on yellowfin tuna for raw-style dishes such as sashimi, poke and tartare. The most important decision is not a marketing phrase such as “sushi grade,” but whether the specific product is intended and handled for raw consumption.
For uniform raw preparations, start with Yellowfin Tuna Saku Blocks. For the full range of cuts, browse the Tuna Collection.

Which Yellowfin Cut Works Best?
Saku blocks are trimmed into a consistent shape, which makes them practical for sashimi slices, poke cubes and tartare. Ahi steaks are better suited to grilling or pan cooking unless the specific product is explicitly intended for raw service. Do not assume that every tuna steak is interchangeable with a raw-service cut.
How to Handle Tuna for Raw Dishes
- Keep the fish refrigerated and follow the storage and thawing instructions supplied with the product.
- Use clean hands, a clean cutting board and a sharp clean knife. Keep raw seafood separate from ready-to-eat foods.
- Cut only the amount you plan to serve and return unused fish to refrigeration promptly.
- If you are uncertain whether a particular product is appropriate for raw consumption, cook it instead.
Raw or undercooked seafood can carry foodborne-illness risk. FDA guidance notes that cooking seafood thoroughly is the safer option, particularly for people at increased risk.
Three Ways to Serve Raw-Style Ahi
Sashimi
Slice chilled saku across the grain with a sharp knife. Serve simply with soy sauce, wasabi and pickled ginger so the tuna remains the focus.

Poke
Cut the tuna into even cubes and dress shortly before serving with soy sauce, sesame oil, scallion and sesame seeds. For a complete bowl, add rice, cucumber, avocado and nori. See our Ahi Tuna Poke Bowl recipe.
Tartare
Dice the tuna by hand and combine just before serving with a restrained dressing such as citrus, sesame oil and scallion. For measured quantities, use our Ahi Tuna Tartare recipe.
Yellowfin Tuna and Mercury
FDA/EPA place yellowfin tuna in the “Good Choices” category in their advice for people who are or might become pregnant, people who are breastfeeding, and children. For that population, a “Good Choice” means one serving that week rather than two or three servings of that fish. Bigeye tuna is in the “Choices to Avoid” category, which is another reason to confirm the species when buying ahi.
About Freezing and the Term “Sushi Grade”
“Sushi grade” is commonly used commercially, but it should not replace product-specific handling information. FDA Food Code parasite-destruction rules include exemptions for several tuna species, including yellowfin, bigeye, albacore and specified bluefin species. That does not make all raw tuna risk-free: time, temperature, sanitation and supplier handling still matter.
Best Product for This Guide
For sashimi, poke and tartare, use Yellowfin Tuna Saku Blocks. If your plan is to cook the fish, compare Ahi Tuna Steaks and other options in the Tuna Collection.
Frequently Asked Questions
Is ahi the same as yellowfin?
Ahi is a market name commonly used for yellowfin and bigeye tuna. Check the species on the product rather than relying on “ahi” alone.
Can I use ordinary tuna steaks for sashimi?
Do not assume so. Confirm that the specific product is intended and handled for raw consumption. When in doubt, cook it.
What cut is easiest for poke and sashimi?
A trimmed yellowfin saku block is convenient because its uniform shape makes even slicing and cubing easier.
Should pregnant people eat raw tuna?
FDA advises people who are pregnant to avoid raw or undercooked seafood because of foodborne-illness risk. FDA/EPA mercury guidance also distinguishes tuna species, including yellowfin and bigeye.
