Can you have oysters if you are breastfeeding?

Yes, you can! Unlike fishes with high mercury content, the concern about having oysters while breastfeeding is the risk of getting food poisoning. Otherwise, the risk of bacteria from the raw fish is unlikely to pose any danger to your child as it will not be passed through breastmilk. I would propose taking it in moderation and best to have it cooked to minimize the chances of food poisoning. Enjoy!
