Lunchbox food safety

We often think about healthy eating when preparing lunches, but it’s important to keep food safety in mind too.

Here are some tips for preventing food-borne illnesses (food poisoning) when you’re making lunch for yourself or your child.

  • Make sure the counter, lunchbox, containers and ice packs are clean.
  • Before preparing the lunch, wash your hands with warm water and soap.
  • Opt for a reusable, insulated lunchbox – it will protect the food and keep it at the right temperature.
  • If you prepare lunch the day before, leave any perishable foods in the refrigerator until morning.
  • Use an ice pack to keep food cool.
  • Use an insulated container (such as a Thermos) to keep hot food hot. First fill the container with boiling water, screw on the lid, and wait about 10 minutes before emptying it and pouring in the heated food.
  • After lunch, throw away all leftover perishable foods (e.g., milk, meat sandwiches, stews).

Bacteria that can cause food-borne illnesses develop very quickly on some foods. Perishable foods (e.g., yogurt, meat, cheese) must stay out of the temperature danger zone (4–60°C) to be safe to eat at lunchtime.

Must remain cold

  • Yogurt, cheese and milk
  • Meat, poultry, fish and seafood
  • Eggs
  • Salads made with legumes, beans, pasta or rice
  • Fruit and vegetables (peeled, cut or leafy)
  • Foods containing mayonnaise or other sauces
  • Tofu spread and hummus

If you heat up food at home, it must be put in an insulated container so that it stays above 60°C.

Can be kept at room temperature

  • Fruit and vegetables (not peeled or cut)
  • Bread, tortillas and pitas
  • Muffins and granola bars
  • Crackers
  • Trail mix with seeds and dried fruits
  • Dry cereals
  • Canned salmon or tuna (unopened)
