Nasty seafood surprise

Pregnant or breastfeeding? Then you need to balance your intake of raw fish and seafood carefully. While it's important to get your omega-3 fatty acids from fish, eating seafood may expose your baby to dangerous heavy metals, toxins and even fish tape worms.

Take action:

  • Don't eat salmon sushi more than once or twice a month – toxins, that are dangerous in large quantities, may be present
  • Don't eat more than two tuna steaks (weighing about 170g raw) per week – larger game fish like tuna may be contaminated with mercury
  • Make sure that you eat fish at a good restaurant that uses frozen supplies – fish that hasn't been frozen, can be a source of fish tape worms (check with restaurant owners that fish has been frozen at -20 degrees Celsius for at least 24 hours).
