What is foodborne illness?
Food contaminated by bacteria, viruses and parasites can make you sick. Many people have had foodborne illness and not even known it. It's
sometimes called food poisoning, and it can feel like the flu. Symptoms may include the following:
- stomach cramps
- nausea
- vomiting
- diarrhea
- fever
Symptoms can start soon after eating contaminated food, but they can hit up to a month or more later. For some people, especially young children,
the elderly, pregnant women and people with weakened immune systems, foodborne illness can be very dangerous.
Health Canada estimates that there are as many as 13 million cases of foodborne illness in Canada every year. Most cases of foodborne illness can
be prevented by using safe food handling practices and using a food thermometer to check that your food is cooked to a safe internal temperature!
It's always important to keep foods out of the danger zone, which is between 4°C (40°F) and 60°C (140°F) to prevent the growth of harmful
bacteria. To do this, just keep hot foods hot, at least 60°C (140°F) and keep
cold foods cold at 4°C (40°F) or lower.
Preparing and serving holiday buffets
- Do not let foods linger during preparation, cook them thoroughly and serve them promptly. Keep hot foods hot with warming trays, chafing dishes
or crock pots. Keep cold foods cold by placing serving dishes on crushed ice.
- Remember the "2-hour rule" especially when entertaining with a large meal or buffet. Don't let perishable foods
linger for longer than two hours in the danger zone.
- Keep replacement dishes of food hot e.g. in the oven or a pot or cold e.g. in
the refrigerator or a cooler during the buffet.
- Do not add new food to a serving dish that has been sitting at room temperature for more than two hours. Remember to change serving utensils as
well.
- Provide serving spoons and tongs for every dish served. Even finger foods, such as cut vegetables, candies, chips/nachos and nuts, should have
serving implements to prevent contamination between guests.
Traveling with food
- Wrap hot food in foil and heavy towels, or carry in insulated containers to maintain a temperature of at least 60°C (140°F).
- Store cold foods in a cooler with ice/freezer packs to maintain the temperature at 4°C (40°F) or below. Full coolers keep their temperature better than partially full ones, so add extra insulation to take up
unoccupied space. This will also prevent containers from sliding, falling over and leaking.
Vegetables, herbs and other foods stored in oil
(e.g. basil or other herbs in oil, garlic, mushrooms, sundried tomatoes, peppers in oil and also pesto or antipasto)
Be sure to carefully store foods in oil to prevent harmful toxins that cause serious illness.
- Home-prepared products in oil can be made safely only by adding dehydrated ingredients to oil. These products can be kept at room
temperature. Dehydrated ingredients include ingredients that are very dry and can be kept at room temperature without spoiling, e.g. dried herbs and spices, dry-packed sundried tomatoes, etc.
- If home-prepared products in oil are made using fresh or frozen ingredients, e.g. fresh basil,
peppers, mushrooms or garlic, they should be kept refrigerated at all times and must be discarded after one week unless properly acidified. These
products may be safely frozen for longer storage. Thaw frozen products in the refrigerator. After the products have thawed, they should be kept
refrigerated at all times and must be discarded after one week unless refrozen.
- Consumers who purchase products made with fresh ingredients from fairs or farmer's markets or receive them as gifts should check
that they were constantly refrigerated after they were prepared, and when they were prepared. Discard them if they are more than one week old.
- Commercially-prepared products in oil that contain an acid (such as vinegar) or salt in their list of ingredients are generally considered to be
safe. Store them in the refrigerator after opening and between each use. Contact the manufacturer if you have questions about a particular
product.
Eggnog and other recipes with raw or lightly cooked eggs
- Be sure to handle and prepare these tasty treats safely. Commercial, ready-made eggnog is prepared using pasteurized eggs and does not require
heating. Homemade eggnog may contain harmful bacteria if not prepared properly. Prepare homemade eggnog using pasteurized egg products, found in most
grocery stores.
- If you choose to make eggnog with whole eggs, be sure to heat the egg-milk mixture to at least 71°C
(160°F). Refrigerate promptly, once steaming stops, dividing large amounts into shallow containers so that it
cools quickly.
- Precautions should also be taken with sauces, mousses, and any other recipes calling for raw or lightly-cooked eggs. Use pasteurized egg
products, or bring egg-mixtures to a uniform temperature of 71°C (160°F).
- All of these foods must be stored in the refrigerator.
Cider
- Popular holiday beverages, such as unpasteurized apple cider and other drinks made from unpasteurized apple cider may pose a safety risk since
they may contain harmful bacteria.
- Serve pasteurized ciders or bring unpasteurized cider to a rolling boil before serving. This is especially important when serving cider to
children, the elderly, and people with weakened immune systems.
Leftovers: Storage and Reheating
- While it is tempting to leave turkey and other foods at room temperature for snacking after a meal, you should refrigerate all leftovers promptly
in uncovered, shallow containers so they cool quickly. Refrigerate once steaming stops and leave the lid or wrap loosely until the food is cooled to
refrigeration temperature. Avoid overstocking the refrigerator to allow cool air to circulate freely.
- Store turkey meat separately from stuffing and gravy.
- Reheat solid leftovers to at least 74°C (165°F). Bring gravy to a full,
rolling boil and stir during the process.
- Use leftover turkey meat, bones, stuffing, gravy and other cooked dishes within four days for best quality or freeze for later use.
Safeguarding Canada's Food Supply
The Canadian Food Inspection Agency (CFIA) is the Government of Canada's key science-based regulator for animal health, plant protection and,
in partnership with Health Canada, food safety. At the CFIA, the safety of Canada's
food supply is central to everything we do.
