"5. Is canned tuna safe to eat regularly?
Yes. In general, it is safe for all population groups, including pregnant women, to consume 2-3 serves of any type of tuna per
week (canned or fresh). Canned tuna generally has lower levels of mercury than other tuna because the tuna used for canning are smaller species that are generally caught when less than 1 year old. FSANZ has calculated that it is safe for all population groups to consume a snack can of tuna (95 grams) everyday, assuming no other fish is eaten. But remember, the Australian Dietary Guidelines recommend that a variety of foods be consumed. "
