Can Mussels Affect Breast Milk?

People who are breastfeeding often wonder if it’s safe to eat mussels and other shellfish, as there is a risk that the food could contain harmful toxins. Mussels themselves are perfectly healthy for you to eat while breastfeeding, but they can be contaminated with toxic substances such as biotoxins and heavy metals 

Eating mussels while breastfeeding should only be done in moderation (1-2 servings per week). To avoid exposure to potentially harmful toxins, choose mussels from local sources that have been tested for contaminants. You can also ask your doctor about taking an algae based supplement like spirulina or chlorella to reduce your risk of exposure to these toxins.
