A best-before date isn’t an expiration date. Which foods still keep for weeks afterward, where the real line is, and when you genuinely need to throw something out.
Can you still eat food after the best-before date has passed?
In most cases, yes. The best-before date states how long the manufacturer guarantees the smell, taste, color, and nutritional value; it isn’t an expiration date. With undamaged packaging and correct storage, many products are still perfectly good to eat well after that date. The use-by date is different: it’s binding, and after it passes, the food belongs in the trash.
The key points:
- Best-before date = a quality promise. Products may still be sold and eaten after it passes.
- Use-by date = a safety limit. It appears on highly perishable food like ground meat, poultry, and fish. Don’t eat it after that date.
- Check in this order: packaging, appearance, smell, a small taste test.
- Around 76 kilograms of food per person per year end up in the trash in German households. A misunderstood best-before date is one of the main reasons.
Good to Know
This article gives general guidance. Stricter standards apply for pregnant women, small children, older people, and anyone with a weakened immune system; when in doubt, throw it out.
What’s the difference between a best-before date and a use-by date?
| Best-before date | Use-by date | |
|---|---|---|
| Wording | “best before” | “use by” |
| Meaning | Quality guaranteed until then | Safety limit |
| Eat it after? | usually yes, after checking | no |
| Sell it after? | allowed | forbidden |
| Typical products | Pasta, canned goods, milk, yogurt, flour | Ground meat, poultry, fish, sushi |
The difference isn’t just a formality: the use-by date is about pathogens that can multiply without any change in smell or appearance. That’s why, in this case, checking it yourself is explicitly not enough.
How long do foods keep past their best-before date?
The following figures apply to unopened products stored correctly. They’re rules of thumb, not a guarantee; they don’t replace checking with your eyes and nose.
| Food | Often still good after the best-before date | Watch for |
|---|---|---|
| Pasta, rice, legumes (dried) | Years | Pests, musty smell |
| Canned goods | 1–2 years | Dents, rust, a bulging lid → throw away |
| Flour | 6–12 months | Rancid smell, moths |
| Honey, sugar, salt | Practically indefinite | Crystallization is harmless |
| Hard cheese | 2–4 weeks | Cut mold away generously |
| Yogurt, quark (unopened) | 1–2 weeks | Mold, bulging, a sour tang |
| UHT milk (unopened) | 2–4 weeks | Curdling, smell |
| Fresh milk | 2–3 days | Smell decides |
| Eggs | 2–4 weeks | Water test, then only fully cooked |
| Chocolate | Months | Gray bloom is just fat, not spoilage |
| Oil | Months | Rancid smell → throw away |
| Frozen food | Months | Freezer burn reduces quality, not safety |
Kitchen Tip
The egg test: place the egg in a glass of cold water. If it sinks flat to the bottom, it’s fresh. If it stands up, it’s older but still usable if fully cooked. If it floats, throw it out.
How do you check whether food is still good?
Work through the four steps in order, and stop as soon as something looks off.
- 1Check the packaging. A bulging lid, a swollen package, rust or dents on a can, a leak: in any of these cases, throw it out without further checking.
- 2Look at it. Mold, discoloration, sliminess, unusual cloudiness, or gas bubbles are all reasons to reject it.
- 3Smell it. Sour, musty, yeasty, rancid, or simply “off” compared to normal: when in doubt, throw it out.
- 4A small taste test. Only if the first three steps were unremarkable, and only for products with a best-before date, never for anything past its use-by date.
When do you have to throw food away?
In these cases, there’s nothing to weigh up:
- A use-by date that’s passed on ground meat, poultry, fish, or sushi
- Bulging or gassing cans and lids: a sign of microbial activity
- Mold on soft foods: yogurt, quark, cream cheese, jam, compote, soft fruit, cooked dishes. The mold’s network runs through the whole product, even where nothing is visible.
- Rancid oil or rancid nuts: the fat breakdown products that form are a health concern
- Anything that smells sour, yeasty, or simply off
For hard cheese, mold isn’t a total loss: because of its firm structure, it’s enough to cut away a generous margin (about two centimeters) around the spot.
How do you keep track?
The practical core isn’t knowing shelf lives; it’s knowing what you actually have. Three habits are enough:
- First in, first out: new items to the back, older ones to the front.
- An “eat this first” box in the fridge for anything that needs to go within the next two days.
- Digital pantry tracking: the le’Chef pantry stores best-before dates, reminds you in time, and suggests recipes that use up exactly that food.

Frequently asked questions
What exactly does “best before” mean?
The manufacturer guarantees that, up to this date, the unopened and correctly stored product keeps its typical qualities: smell, taste, color, texture, and nutritional value. It explicitly says nothing about the point at which the food actually becomes inedible.
Can a supermarket sell food after its best-before date has passed?
Yes. After the best-before date passes, food may still be sold as long as it’s in perfect condition; the retailer is then responsible for making sure it’s fit for sale. Selling food past its use-by date, on the other hand, is forbidden.
How long does yogurt keep after its best-before date?
Unopened yogurt that’s been kept consistently cold is often still good one to two weeks past the best-before date. Check the lid, the surface, and the smell: a bulging lid, spots of mold, or a sharp sour smell mean it should be thrown out. Whey separating on top, though, is normal and can be stirred back in.
Can I just cut mold off?
Only with firm foods like hard cheese: there, cutting away a generous two centimeters around the spot is enough. With soft, moist foods like yogurt, jam, soft cheese, fruit, or cooked dishes, that’s not enough, because the mold’s network runs invisibly through the whole product.
Is frozen food still safe after its best-before date?
If it’s been kept consistently frozen at minus 18 degrees, frozen food stays microbiologically safe even past its best-before date. What suffers is quality: freezer burn dries out the surface and costs flavor and texture, but it isn’t a health risk.
