The MacDonald's Fillet of Fish is made from New Zealand Hoki Fillets.
Hoki is a white fleshed, low mercury fish, which you could eat every day with no accumulation risk. It is not hake, not a danger during pregnancy.
Hake itself is also not a high risk fish during pregnancy, again it is a white fleshed fsh, not classed as an oily or high mercury fish.


I just googled Hoki and it says "Hoki is a type of fish in the hake family, found off the coasts of New Zealand and Australia. "
