Why is there consumption advice for fresh/frozen yellowfin tuna but not canned yellowfin tuna?
Some data suggest that yellowfin tuna steaks contain lower amounts of mercury than other species of tuna that are sold fresh/frozen, such as bigeye. As there are insufficient Canadian data for fresh/frozen yellowfin tuna and it is not always possible to know the species of fresh/frozen tuna that you are purchasing at the fish counter, the advice continues to cover all fresh/frozen tuna.
