Kirkland Signature Fresh Wild Ahi Tuna is a premium yellowfin tuna sold by the pound in Costco's refrigerated seafood section. Wild-caught and vacuum-sealed for freshness, each package typically weighs around 2 pounds and arrives as thick, sashimi-grade steaks with a deep red color and clean ocean flavor.

This tuna is prized for its versatility and quality. It is commonly used for searing rare, grilling, poke bowls, sashimi, and sushi preparations. The fresh (never frozen) steaks are suitable for raw preparations when handled properly. The sell-by date is typically about 3 days from the pack date, and the steaks can be frozen at home for longer storage.

Ahi tuna is a lean, high-protein fish rich in omega-3 fatty acids. A 5 oz serving provides approximately 163 calories, 31g of protein, and 2.5g of fat.
