Question: is tuna safe to eat during pregnancy?
Answer: When you're pregnant or trying to get pregnant, you should limit the amount of tuna you eat because it also contains high levels of mercury. Don't eat more than: 2 tuna steaks a week (each weighing about 140g when cooked or 170g when raw), or. 4 medium-sized cans of tuna a week (about 140g a can when drained)
