USE LEFTOVERS WELL

Make leftovers useful and handle them safely

Leftovers are useful ingredients, but safe handling comes first. Check how the food was stored and use official guidance for its type. If you are unsure how long it has been out or whether it was kept cold, do not rely on smell or appearance alone.

Store promptly

Health Canada advises refrigerating or freezing leftovers within two hours. Divide a large amount into shallow containers so it cools faster, and keep refrigerator temperature at 4°C (40°F) or lower. Follow current local guidance for your specific food.

Use a clear date

Label containers with the date, and follow official storage time guidance. Health Canada’s general advice is to consume or freeze refrigerated leftovers within four days. Some foods have different requirements, so check the relevant guidance rather than treating one time limit as universal.

Reheat thoroughly

Reheat leftovers to a safe internal temperature using an appropriate food thermometer and government guidance. Heat only the amount you plan to eat where practical, and avoid repeated cooling and reheating cycles.

Give leftovers a new role

A cooked grain can become a warm bowl or a soup base; roasted vegetables can be folded into eggs or pasta; cooked beans can become a spread or filling. Add something fresh or crisp and a bright finishing note to make the meal feel different.

Discard when safety is uncertain

Do not taste food to determine whether it is safe. When you cannot confirm that leftovers were cooled and stored appropriately, discard them. People at higher risk from foodborne illness should be especially cautious and follow public-health guidance.
