A portion is left over, the food was good – so take it home. This saves food and can be a treat again the next day. In summer, however, the way you transport it determines whether the leftover becomes a practical meal or an unnecessary risk. With these six steps, the cold chain remains as short and manageable as possible.
1. Only have fresh leftovers packed
Decide as soon as possible after eating. If the dish has already been standing unrefrigerated on the table for a long time or if it is unclear how long it was kept warm, it should not be taken home. Smell and appearance alone are not a reliable safety check. Be particularly careful with highly perishable foods, such as dishes containing raw eggs, fish, seafood, or delicate creams.
2. Use a clean, well-sealing box
Ask for a suitable takeaway box at the restaurant or use a clean, food-safe container with a tight lid. Keep liquid and solid components separate if possible. This prevents leaking and makes even reheating easier later on. The Austrian environmental consultancy explicitly recommends taking leftovers home as a simple contribution to reducing food waste and also mentions the reusable "Genuss Box" for this purpose.
3. Go straight home
The box should not be left on the table, in a parked car, or in direct sunlight for another hour. Only accept the leftovers when you are ready to leave and take them home as directly as possible. This applies even if the outside of the packaging still feels cool.
4. Plan a cooler bag in hot weather
For longer journeys, trips on public transport, or high outdoor temperatures, a small cooler bag with a cooling pack is the more reliable solution. The Austrian health portal recommends transporting sensitive foods chilled. If you often eat away from home in summer, you can keep a flat cooler bag permanently in the car or in your work bag – of course, insert the cooling pack only shortly before you leave.
5. At home: cool immediately and quickly
Put leftovers covered in the refrigerator as soon as you arrive. A temperature of one to five degrees Celsius is recommended there. Small, shallow portions cool down faster than a large, deep container. Further practical tips can be found in the article Storing food correctly in heat. For vulnerable people, the overview Avoiding Listeria in the refrigerator is also helpful.
6. Only take out once and reheat thoroughly
Only take out the portion that will actually be eaten. Cooked foods should be heated completely and evenly to at least 65 degrees Celsius before consumption. If there is an unusual smell, visible spoilage, or mold: discard it, do not taste. If cooling was uncertain while traveling, exercising caution is also the better choice.
The 60-second check before heading home
- Has the dish been fresh so far and only been unrefrigerated for a short time?
- Is the box clean, food-safe and able to be closed tightly?
- Are you going straight home?
- Is a cooler bag available in case of heat or a longer journey?
- Can the portion be refrigerated immediately at home?
If any of these conditions are missing for a sensitive dish, it's better to leave the leftovers behind. That way taking food home won't be a dare but a sensible measure against food waste.
