Can I use Costco tuna for sushi?
Nothing compares to making sushi at home. And ahi tuna is one of the best sushi ingredients.

Here’s what I’ve found: Yellowfin tuna, one of the two fish commonly referred to as ahi tuna, is available at Costco in sashimi-grade, ultra-frozen form.
- Bigeye tuna is the other species that is typically unavailable at Costco.
- In addition, they provide wagyu sashimi-grade Hamachi, also known as yellowtail.
- This is also suitable for sushi.
- However, not even sushi-grade fish is risk-free.
- But yellowtail and yellowfin tuna should not be confused.
- Yellowtail/hamachi is not a type of tuna.

In fact, most grocery stores do not label fish as “sushi-grade” because they fear being held liable if someone eats it, gets sick, and claims it was the tuna.
