Wondering how long food lasts in the fridge, whether yesterday’s spaghetti sauce is still within its recommended storage time, or how long opened milk should be kept?
The Food Storage Time Finder gives you practical refrigerator and freezer guidance for everyday foods. Search for what you have, choose your region, and the finder will use the appropriate storage guidance for Canada, the United States, the United Kingdom, Ireland, Australia, New Zealand or international WHO guidance.
It also considers details that can change the answer, such as whether a food is opened or unopened, homemade or commercially packaged, and how long it may have been outside the refrigerator.
How to Use the Food Storage Time Finder
Start typing the food you want to check. You can use normal kitchen language such as spaghetti sauce, Bolognese, opened milk, leftover rice, chicken breast or takeout.
When more information is needed, the finder may ask a quick follow-up question. For example, spaghetti sauce could mean homemade meat sauce, meatless tomato sauce or an opened jar of commercial pasta sauce — and those do not always have exactly the same storage guidance.
Then:
- Choose your guidance region.
- Search for the food.
- Select whether it is in the refrigerator or freezer.
- Optionally enter how long it has already been stored.
- Tell the finder if it spent significant time outside refrigeration.
- Select Find Storage Guidance.
Food Storage Time Finder
Find practical refrigerator and freezer guidance for common foods using official recommendations for your region. Add how long the food has been stored for a more useful result.
Best-before dates and opened food are not the same thing
A best-before date generally describes the expected quality of an unopened product when it has been stored correctly. Once a package is opened, the food may have a much shorter recommended storage time.
For example, fresh milk can still show a best-before date several days away, but after opening you should follow the shorter opened-storage guidance for your region or the package if it gives a more restrictive instruction.
Use-by dates are different: where a food has a use-by date for safety, do not use the Food Storage Time Finder to extend that date.
Why search terms can share an answer: foods such as spaghetti sauce, Bolognese and meat sauce may use the same underlying cooked-leftover rule. The finder maps everyday food names to the appropriate official storage category rather than inventing a different safety limit for every recipe name.
How Long Does Food Last in the Fridge?
There is no single refrigerator storage time that works for every food.
Raw ground meat may only have a day or two of recommended refrigerated storage, while eggs can last for weeks. Cooked leftovers usually fall somewhere in between. Storage times can also change depending on whether a package has been opened and which country’s food-safety guidance you are following.
For example, Health Canada recommends eating refrigerated leftovers within about 2–3 days in its general leftover guidance, while its detailed storage chart gives 3–4 days for several cooked meat and vegetable dishes. U.S. FoodSafety.gov generally gives 3–4 days for cooked leftovers.
That is why the finder asks for both the food and your region instead of giving everyone the same generic answer.
Why Food Storage Times Vary by Country
Food-safety authorities do not always publish exactly the same recommendations.
For example:
- The United Kingdom advises eating refrigerated leftovers within 48 hours or freezing them.
- The Food Safety Authority of Ireland recommends using refrigerated leftovers within 2–3 days.
- New Zealand Food Safety recommends 2 days for rice-based leftovers and cooked foods normally eaten cold, while leftovers that will be reheated hot can be kept for up to 4 days.
- Australia uses specific temperature-control guidance, including its 2-hour / 4-hour rule for potentially hazardous foods held between 5°C and 60°C.
Instead of hiding these differences, the Food Storage Time Finder lets you choose the guidance that applies to you.
Best-Before Dates and Storage Time After Opening Are Different
A best-before date does not necessarily tell you how long a food should be kept after you open it.
In Canada, best-before dates relate to the quality and shelf life of an unopened product stored as directed. Once the package is opened, its storage life can change.
Milk is a good example.
A carton you buy today might have a best-before date a week away. While it remains unopened and properly refrigerated, that printed date is useful guidance. Once the carton is opened, however, Health Canada’s food-storage chart recommends about 3 days for opened milk.
So these two statements can both be correct:
Unopened milk: follow the best-before date on the carton.
Opened milk: follow the shorter opened-storage recommendation or any more restrictive instruction on the package.
The finder separates opened and unopened foods where that distinction matters.
What About Use-By Dates?
A use-by date should not be treated the same way as a best-before date.
Best-before dates generally concern quality. A use-by date may be used where the date is more important to safe use of the food.
The Food Storage Time Finder should never be used to extend a package’s safety-related use-by instruction. If the package or your local food authority gives a shorter storage period than the finder, follow the shorter instruction.
Refrigerator Times and Freezer Times Mean Different Things
A refrigerator storage limit and a freezer storage recommendation are not always measuring the same thing.
Health Canada says its recommended refrigeration times are for safety, while its freezer times are primarily about maintaining quality. FoodSafety.gov similarly states that food kept continuously frozen at 0°F / -18°C or below can remain safe beyond the recommended freezer times, although flavour and texture may decline.
That is why the finder may say:
Beyond recommended refrigerator time — discard
but for a frozen food say:
Past best-quality freezer window
Those are deliberately different messages.
How Long Can Food Stay Out of the Fridge?
For many perishable foods, storage time in the refrigerator is only useful if the food was refrigerated promptly in the first place.
Health Canada advises throwing away cooked food that has been left at room temperature for more than 2 hours.
WHO’s international guidance also recommends that cooked food should not remain at room temperature for more than 2 hours and that cooked and perishable foods should be refrigerated promptly, preferably below 5°C / 41°F.
Australia uses a more detailed 2-hour / 4-hour rule for potentially hazardous food:
- Less than 2 hours: it can generally be used or refrigerated again.
- Between 2 and 4 hours: use it immediately; do not put it back in the refrigerator for later.
- More than 4 hours: discard it.
The finder takes these regional differences into account.
Why “Spaghetti Sauce” May Need Another Question
Food names can be deceptively simple.
Someone asking “How long does spaghetti sauce last in the fridge?” might mean:
- homemade Bolognese with meat
- homemade tomato sauce without meat
- marinara
- an opened jar of commercial pasta sauce
Rather than pretending all four are identical, the Food Storage Time Finder asks for clarification when that information could change the recommendation.
At the same time, it does not create a made-up safety rule for every recipe name. Foods such as Bolognese, meat sauce and spaghetti sauce with meat can often be mapped to the same underlying cooked-leftover guidance.
This lets you search using normal kitchen language while the finder works from established food-storage categories behind the scenes.
Can You Tell if Food Is Safe by Smelling It?
Not reliably.
Spoilage can certainly produce unpleasant smells, mould or changes in texture, but food that looks and smells normal can still contain harmful microorganisms.
Health Canada specifically warns that you cannot determine whether food is unsafe by smell or taste.
So the sniff test should not be used to extend a recommended food-safety storage limit.
When in doubt about a potentially hazardous food, throwing it away is safer than tasting it to find out.
What Temperature Should a Refrigerator Be?
The recommended refrigerator temperature varies slightly in how authorities express it.
In Canada and the United States, refrigerator guidance generally uses 4°C / 40°F or below.
Ireland recommends refrigerators between 0°C and 5°C, while WHO recommends refrigerating cooked and perishable foods promptly, preferably below 5°C.
If your refrigerator is warmer than the recommended range, the normal storage times should not be assumed to apply.
International Food Storage Guidance
The Food Storage Time Finder currently includes:
- Canada
- United States
- United Kingdom
- Ireland
- Australia
- New Zealand
- International / WHO Guidance
The international option is useful when your country is not listed. It uses broad World Health Organization food-safety principles rather than pretending there is one worldwide food-by-food storage chart.
WHO recommends promptly refrigerating cooked and perishable foods, preferably below 5°C, and not leaving cooked food at room temperature for more than 2 hours. Its Five Keys manual also advises that refrigerated leftovers generally should not be kept for longer than 3 days.
For foods where WHO does not provide a specific universal storage time, the finder tells you to follow your local food authority and package instructions rather than inventing a number.
Frequently Asked Questions
How long are leftovers good for in the fridge?
It depends on your region and the type of leftovers. In Canada, Health Canada advises using refrigerated leftovers within about 2–3 days in its general leftover guidance, while some specific cooked foods in its storage chart have 3–4 day recommendations. The finder uses the most appropriate category available.
How long does spaghetti sauce last in the fridge?
It depends on what kind of sauce it is. Homemade meat sauce is generally treated as a cooked leftover, while an opened commercial pasta sauce may have its own manufacturer’s storage instruction. Search spaghetti sauce in the finder and choose the version that matches what you have.
How long does opened milk last?
This varies by region and product. In Canada, Health Canada’s storage chart recommends about 3 days for opened milk at 4°C / 40°F or below. Unopened milk is instead listed according to its best-before date.
Can I eat food after its best-before date?
A best-before date is generally about the quality of an unopened food rather than a universal safety cutoff. However, perishable foods still need to be stored correctly, and some foods can become unsafe without obvious signs. Follow safe storage guidance and any applicable use-by instructions.
Does freezing food make it last forever?
Continuous freezing greatly extends storage. U.S. FoodSafety.gov explains that its freezer storage times are primarily for quality and that foods continuously held at 0°F / -18°C can remain safe longer, although their quality can deteriorate.
Can I rely on smell to decide if leftovers are safe?
No. Harmful contamination does not always cause a noticeable smell, flavour or appearance change. Use recommended storage and handling guidance instead.
What if my food is not listed?
Try a broader everyday description. The search recognizes alternate names and maps many foods to an appropriate underlying category. We can also continue expanding the finder as new foods and aliases are added.
