Kirkland Signature Fresh Wild Ahi Tuna is premium-quality yellowfin tuna sold by the pound from Costco's refrigerated fish and seafood section. Wild caught in the Philippines and processed in the United States, each package typically weighs around 2 pounds and features thick, deep-red steaks with a firm, meaty texture.

This tuna is fresh and has never been frozen, making it suitable for a wide range of preparations including searing rare, grilling, slicing for sashimi, or using in poke bowls and Asian-inspired dishes. Because it arrives fresh rather than frozen, you can purchase it and freeze it at home to extend its shelf life. The sell-by date is approximately 3 days after the pack date. Costco's cooking guidelines recommend bringing the tuna to a minimum internal temperature of 145°F when cooking fully.
