Food safety for pregnant women
Pregnancy can be one of the most exciting times in your life. Following a healthy diet is an important way to make sure that you and your baby are getting the nutrients that you need.
However, because of all the changes taking place in your body, both you and your unborn baby are at an increased risk for food poisoning (also known as food-related illness or foodborne illness). This includes your immune system being weakened, which can make it more difficult to fight off infections.
While the food we eat in Canada is among the safest in the world, some food can be contaminated by bacteria, viruses, and parasites (foodborne pathogens). Protect yourself and your baby by following some simple rules and by avoiding some types of food.
Some people can get food poisoning and not even know they have it. Food poisoning is caused by eating foods that are contaminated.
Certain bacteria, viruses or parasites can cross the placenta and increase the chance your baby may become infected. Your unborn baby's immune system is not developed enough to fight off harmful bacteria. For you, the mother, food poisoning can cause symptoms that include:
- abdominal pain
- body aches
Did you know?
Pregnant women are 20 times more likely than other healthy adults to develop listeriosis if they are exposed to the Listeria bacteria.
Foodborne bacteria can be even more dangerous for your baby's health. If you develop food poisoning during the first three months of pregnancy, it can cause a miscarriage. Later on in the pregnancy, your baby could be delivered prematurely. Foodborne illness can also cause a stillbirth or a baby who is born severely ill. Since your baby is dependent on you for all its needs, it is extremely important that you pay close attention to what you eat and apply the following food safety steps.
It is important to separate your raw meat, poultry, fish, and seafood from other food in your grocery cart and in your refrigerator. This is to make sure that you are not cross-contaminating your food.
Heat and proper cooking can kill bacteria, but people often eat raw fruits and vegetables. Because they are not heated or cooked, raw fruits and vegetables that have been contaminated by raw meat, poultry, fish, and seafood may contain bacteria that can be harmful to you.
- Buy cold or frozen food at the end of your shopping trip.
- Check the "best before" date on your food.
- Keep your raw meat, poultry, fish, and seafood away from other food in your grocery cart.
- Examine fruits and vegetables carefully and avoid buying items that are bruised or damaged.
- If you use reusable grocery bags or bins, make sure to use a specific bag or bin for meat, poultry or seafood. Label the bag or bin with the type of food it carries.
Did you know?
You can't tell if food is unsafe by its smell or taste. When in doubt, throw it out!
Cleaning your hands, kitchen surfaces, utensils, fruit and vegetables, and reusable grocery bags will help eliminate bacteria and reduce the risk of food-related illness.
- Use regular soap to wash your hands. An alcohol-based hand rub can be used if soap and water are not available.
- Use one cutting board for produce, and a separate one for raw meat, poultry, fish and seafood.
- Use paper towels to wipe kitchen surfaces, or change dishcloths daily to avoid the risk of cross-contamination and the spread of bacteria. Avoid using sponges, as they are harder to keep bacteria-free.
- Sanitize countertops, cutting boards, and utensils before and after preparing food. Use a kitchen sanitizer (following the directions on the container) or a bleach solution (5 ml household bleach to 750 ml of water), and rinse with water.
It is important to keep cold food cold and hot food hot, so that your food never reaches the "temperature danger zone." This is where bacteria can grow quickly and cause food poisoning.
- Keep your raw meat, poultry, fish, and seafood cold. Refrigerate or freeze them as soon as you get home from the grocery store.
- Make sure your refrigerator is set at 4 °C (40 °F) or lower and your freezer at -18 °C (0 °F) or lower. This will keep your food out of the temperature danger zone between 4 °C (40 °F) to 60 °C (140 °F) where bacteria can grow quickly.
- Place raw meat, poultry, fish, and seafood in sealed containers or plastic bags on the bottom shelf of your refrigerator so raw juices won't drip onto other food.
- Deli meats can be more risky for older adults to eat. Store deli meats in the refrigerator and use them within four days or, preferably, two to three days after opening.
- Cook raw meat, poultry, fish, and seafood no more than two to three days after purchasing. If you do not intend to cook it within this time, it should be frozen.
The safest way to thaw food, especially raw meat, poultry, fish or seafood, is in the refrigerator. Always defrost food in the refrigerator, in cold water or in the microwave - never at room temperature. Don't re-freeze thawed food. Remember, to avoid cross-contamination thoroughly wash your hands and clean and sanitize the sink and all other utensils, surfaces, and dishes that you use when thawing the food.
Did you know?
Colour does not always tell you if your food is safe to eat. Always follow internal cooking temperatures to be safe!
Cooking food properly is the best way to make sure it is safe to eat. Bacteria like E. coli, Salmonella, and Listeria are killed by heat.
- Cook food completely, using a clean thermometer to measure the temperature. See Health Canada's safe internal cooking temperatures to learn the proper way of taking measurements and to make sure that the food has been cooked to a safe internal temperature.
- If you are cooking several pieces of meat, poultry, fish or seafood, make sure to check the internal temperature of the thickest pieces because food can cook unevenly.
- Cut away any bruised or damaged areas, since harmful bacteria can thrive in these areas.
- Make sure that cooked foods don't come into contact with any food that hasn't been cooked.
- Keep hot foods at or above 60ºC (140°F). Bacteria can grow quickly in the danger zone between 4°C to 60°C (40°F to 140°F).
- Refrigerate or freeze all leftovers within two hours to minimize the chance of bacteria growing.
- To store leftovers safely, cut and debone the meat from large cooked birds.
- Avoid overstocking the refrigerator, so that cool air can circulate effectively.
- Use refrigerated leftovers as soon as possible, ideally within two to four days.
- When reheating food, make sure it's cooked to a temperature of at least 74°C (165°F). In general, you shouldn't reheat the same leftovers more than once.
Select safer alternatives
Some types of food can be a higher risk for pregnant women because of the way they are produced and how they are stored. You can minimize your chances of getting food poisoning by avoiding some types of food. The following chart can help you make alternative choices when selecting food.
(Always refer to safe internal cooking temperatures.)
|Type of food||Food to avoid||Safer alternative|
