What type of tuna is sushi grade?

Sushi-grade tuna typically refers to species such as Bluefin, Yellowfin, and Bigeye tuna. These fish are considered sushi grade when they are caught, handled, and stored in a way that ensures their freshness and safety for raw consumption. The term "sushi grade" is not a formal certification but indicates that the fish meets high standards for quality and is free from parasites. Always ensure that you purchase from reputable sources to guarantee the freshness and safety of the fish.
