Pregnancy and Food Safety

It’s important for pregnant women to be careful about taking medications during pregnancy and to avoid certain foods.

Fish/Wild Game

  • Fish that contain higher levels of mercury that may harm the fetus: swordfish, fresh or frozen tuna.
  • Health Canada says these kinds of fish should be eaten only once per month during pregnancy.
  • Canned tuna is safe.
  • Ask your doctor if you are unsure whether you should eat foods during pregnancy.


It’s important that a pregnant woman’s diet contains enough iron and enough folate for the fetus

  • Consuming too much Vitamin A can be toxic and can increase the risk of birth defects.
  • Be careful when you buy vitamins

Important: Folic Acid Water

  • To avoid lead concentration in your tap water run the water at the start of the day for at least two minutes.
  • Don’t drink hot tap water—it contains more lead.
  • Boil untreated water for at least one minute before drinking.
  • Alternatives: drinking bottled water or using a water purifier.

A common bacteria in food is called Listeria

  • If consumed it can result in: premature birth, miscarriage, stillbirth.

  • Salmonella
