What is sushi grade tuna and is it bad for the environment?



  1. 0 Votes

    Since tuna used for sushi is typically eaten raw, sushi grade tuna must adhere to specific standards for what temperature and for how long it is frozen before being served. Freezing the fish ensures that any trace microbes or bacterias are killed, rendering the fish harmless for human consumption. However, the FDA seems rather casual with regards to its regulations for attaching the ‘sushi grade’ label to fishes.
