Yes, yellowfin tuna can be eaten raw when it has been handled and stored for raw consumption. Fresh-looking fish alone is not a safety guarantee, so buy it from a reliable seller and keep it properly chilled.
Cook yellowfin tuna steaks quickly in a very hot pan or on a grill. Pat the fish dry first and avoid prolonged cooking; because the meat is lean, it can become dry and tough when overcooked.
Yellowfin tuna contains mercury, as do other large predatory fish. Avoid making it an everyday choice, and take extra care when choosing fish for young children, who are more vulnerable to the effects of mercury.
Usually, yes: “ahi” commonly refers to yellowfin tuna, especially on restaurant menus. The name can also be used for bigeye tuna, so it does not always identify the species precisely.
Yes, yellowfin tuna is often served medium rare, with a seared outside and a pink center. Use fish intended for raw or lightly cooked preparations, handle it hygienically, and cook it fully if you need to avoid raw fish.
Yellowfin tuna has a savory, meaty flavor that is milder than some oily fish. Its firm texture makes it suitable for searing or grilling, while raw preparations showcase its clean taste.
Yes, you can freeze yellowfin tuna. Wrap it tightly to limit air exposure, then thaw it in the refrigerator rather than on the counter. Do not refreeze it after it has thawed.
Fresh yellowfin tuna should smell mild and briny, with firm, moist-looking flesh. A sharp, sour, or ammonia-like smell, or a sticky surface, is a warning sign; do not eat fish with those qualities.
Yes, yellowfin tuna can be eaten during pregnancy, but its mercury content makes portion and frequency important. Ask your doctor or dietitian which fish choices and amounts are appropriate for your pregnancy.
Keep fresh yellowfin tuna in a covered container in the coldest part of the refrigerator and cook it as soon as possible. Store it below ready-to-eat foods so its juices cannot drip onto them.

Yellowfin tuna is a large, warm-water tuna with firm, meaty flesh. It is sold fresh as steaks or loins and also widely available canned; fresh cuts are popular in seafood cuisines around the world, while canned tuna is an easy staple for home cooking. Its mild, savoury flavour works well with bright, simple seasonings rather than heavy sauces.
Sear or grill fresh tuna briefly to keep it moist, or flake canned tuna into salads, sandwiches and pasta. It is naturally high in protein and contains no carbohydrates. For a lighter meal, pair it with vegetables, citrus and a modest amount of dressing; canned tuna also makes a convenient quick lunch.
Very high
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
