What foods should pregnant women avoid?
Should not eat raw eggs, meat, poultry or fish. Even sushi.
Poultry and associated products may contain salmonella or other harmful bacteria. Additionally, fish may contain high levels of mercury (especially oily, red fleshed fish and shark).
High levels of mercury can be very damaging and cause developmental delays in babies.
