It’s usually safe to eat sushi and other dishes made with raw fish when you’re pregnant, if you get them from very reliable high-quality sources and if the fish had been frozen before.
What to eat:
You may need to make sure that the fish has been frozen first, which kills some harmful bacteria.
- Sushi made with cooked fish
- Sushi made with cured fish from reliable sources
What to eat with consideration:
- Raw fish can contain small parasitic worms, such as anisakis. Freezing fish kills any worms and makes it safer to eat. If you make homemade sushi, freeze the fish for at least 4 days before using it.
- Certain farmed fish, destined to be eaten raw, no longer need to be frozen beforehand. This is because these particular types of farmed fish, salmon is one, are very unlikely to contain parasitic worms because of the rearing methods used.
- You should also limit the amount of some types of fish, such as tuna and oily fish.
What to avoid:
When you’re pregnant, you should only eat cooked shellfish. Raw shellfish can contain harmful viruses and bacteria that can cause food poisoning.
