How Long Do Chilled Ready Meals Last? A Food Safety Guide
17 August 2026 · 7 min read
"How long will this actually keep?" is the most common question we get about chilled meals — and the answer people find online is usually vague. Here's the practical version, based on how Australian food safety rules work.
Use-by vs best-before: not the same thing
In Australia, a use-by date is a safety date. Food Standards Australia New Zealand prohibits the sale of food after its use-by date, and you shouldn't eat it after that day either — spoilage bacteria and pathogens aren't always visible or smellable. A best-before date is a quality date: the food may lose texture or flavour after it, but it's still safe if stored properly.
Chilled ready meals almost always carry a use-by date. Treat it as a hard stop.
Typical fridge life by meal type
| Meal type | Unopened fridge life | After opening |
|---|---|---|
| Supermarket chilled ready meal | 3–7 days from purchase | Within 24 hours |
| Meal-prep service (cook-chill, sealed) | 5–10 days | Within 24 hours |
| High-barrier sealed cook-chill (e.g. Sona's Kitchen) | 14–17 days | Within 24 hours |
| Home-cooked leftovers in a container | 2–3 days | Within 24 hours |
The reason a professionally produced cook-chill meal outlasts your own leftovers isn't preservatives. It's process: cooking to a validated core temperature, rapid blast-chilling through the danger zone, sealing in a controlled environment, and an unbroken cold chain to your door.
Storage rules that actually matter
- Keep your fridge at 5°C or below — use a fridge thermometer, not the dial.
- Store meals on a shelf, not in the door, where the temperature swings most.
- Don't re-chill a meal that has been fully reheated. Reheat once, eat once.
- Follow the 2-hour / 4-hour rule: under 2 hours out of the fridge, refrigerate or eat; 2–4 hours, eat now; over 4 hours, throw it out.
- You can freeze most chilled meals before the use-by date if you won't get to them in time — texture in cream- and yoghurt-based sauces will suffer.
How to reheat safely
Reheat until the meal is steaming hot all the way through — 75°C at the centre is the standard target. In a microwave, stir or rotate halfway and let the meal stand for a minute so heat evens out. Cold spots, not the average temperature, are what cause problems.
Signs to throw it out
- Past the use-by date — no exceptions.
- A puffed or bloated seal on the tray.
- Sour, yeasty or ammonia-like smell on opening.
- Slimy texture or visible mould.
- It was left out of the fridge for more than 4 hours.
Related questions
- Can I eat a chilled ready meal one day after the use-by date?
- No. The use-by date is a food safety date, not a quality suggestion. Harmful bacteria can be present without any change in smell, look or taste. If it's past the use-by date, discard it.
- How long do chilled ready meals last once opened?
- Eat within 24 hours and keep the meal refrigerated at 5°C or below in the meantime. Once the seal is broken, the protective packaging environment is gone.
- Can I freeze a chilled ready meal?
- Yes, as long as you freeze it before the use-by date and it hasn't already been reheated. Defrost in the fridge, not on the bench, and eat within 24 hours of defrosting. Cream-based curries may separate slightly on thawing.
- Why do chilled meals last longer than my leftovers?
- Commercial cook-chill uses validated cooking temperatures, rapid blast-chilling, hygienic sealing and an unbroken cold chain. Home kitchens can't match the cooling speed or the sealed environment, which is why leftovers get 2–3 days.
