Ayam Brand™ also recommends reading the following advice on fish consumption, done the Food Standards Australia and New Zealand:

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 flsh is eaten. But remember, the australian dietary guidelines recommend that a variety of foods be consumed.
