Best Before vs Use By: What Food Date Labels Really Mean

The simple difference can help you protect your household, save money, and throw away less food.


QUICK ANSWER

In New Zealand and Australia, a use-by date is about safety: do not eat food after that date. A best-before date is about quality: correctly stored food may still be safe after the date, although its taste, texture, or freshness may decline. Always follow the storage and after-opening instructions on the package.


You open the fridge, find a yoghurt dated yesterday and pause. Is it unsafe, or simply past its best? The answer depends on the exact words beside the date.


Confusing a best-before date with a use-by date can work in both directions. You might throw away perfectly edible food, or take a risk with food that should be discarded. Learning the difference gives you a clearer, safer way to decide what to keep, use first, freeze, or bin.


Best Before vs Use By at a Glance

Label

What it means

What to do

Use by

A safety date in New Zealand and Australia

Use it, cook it, or freeze it before the date. Do not eat it after the date, even if it seems fine.

Best before

A quality date

After the date, check that it was stored correctly and assess its condition. Quality may be lower.

After opening

The printed date may no longer be the whole story

Follow directions such as “refrigerate after opening” or “use within three days,” and note when you opened it.


What Does a Use-By Date Mean?


In New Zealand and Australia, a use-by date marks the point after which a food may pose a health or safety risk. New Zealand Food Safety advises that food can make you sick after its use-by date even when it looks, smells, or tastes normal.


That last detail matters. A sniff test cannot reliably detect every harmful microorganism, so use-by food should not be judged by appearance alone.


You will usually see use-by dates on foods that need tighter safety controls. Whatever the product, the action is the same: follow the date and the storage instructions on the package. If you will not use the food in time, freeze it before the use-by date when the label and official guidance say freezing is suitable.


SAFETY RULE

Past the use-by date in New Zealand or Australia? Do not eat it. When in doubt about a high-risk food, follow the package and official food-safety advice rather than relying on smell or appearance.


What Does a Best-Before Date Mean?

A best-before date tells you when a food is expected to retain its best quality. Food Standards Australia New Zealand explains that food may still be safe after this date, provided it has been stored correctly and has not deteriorated.


After a best-before date, you may notice changes such as softer texture, less crunch, fading flavour, or staling. Those are quality changes, not automatic proof that the food is unsafe.


Before keeping or eating a product past its best-before date, check four things:


Storage: Was it kept exactly as the label directs, including refrigeration where required?

Packaging: Is the seal intact, with no swelling, leaking, rust, or serious damage?

Condition: Is there mould, an unusual smell, unexpected texture, or another clear sign of spoilage?

After-opening guidance: Did the product say to use it within a shorter period once opened?


Do not taste food to find out whether it is safe. If the package is damaged, storage history is uncertain, or the food appears spoiled, discard it.


A Five-Step Routine to Use Food Before Its Date

Understanding the label prevents unnecessary waste. A small routine prevents the food from being forgotten in the first place.


Record the date when food comes home. Add the products you are most likely to lose track of, such as yoghurt, deli items, fresh proteins, sauces, pantry back-ups, and freezer meals. Start with a manageable category instead of trying to catalogue the whole kitchen at once.


Create a use-first view. Keep the foods with the nearest relevant dates visible. In a physical fridge, that might be a front shelf or a small “use first” zone. In Shelve, expiry awareness helps you notice items before they become an unpleasant surprise.


Plan one meal around what needs attention. Before choosing a full week of recipes, select one or two ingredients that should be used soon. Then build a meal around them and add only the missing ingredients to your grocery list.


Freeze early, not as a rescue after the date. If plans change, decide whether suitable food can be frozen while it is still within its date. Label the container with what it is and when it was frozen, then add it to your freezer inventory.


Mark the opening date. For jars, sauces, stocks, dairy products, and leftovers, the opening or cooking date may become more useful than the original best-before date. Follow the package’s after-opening instructions.


How Shelve Fits Into the Routine

Shelve connects pantry tracking, meal planning, recipes, expiry awareness, and grocery lists in one flow. The useful part is not simply storing a date. It is seeing that date early enough to make a better decision.


For example, when spinach, yoghurt, and an open jar of sauce need using soon, you can:

  • See the items in your kitchen inventory

  • Choose or save a recipe that uses them

  • Add the meal to your plan

  • Build a grocery list for only the ingredients you are missing


That pantry-to-meal-to-grocery workflow reduces the chance that date tracking becomes another list you maintain but never use.

A Note for Readers in the United States

Date-label language is not uniform across countries. In the United States, USDA guidance says that, except for infant formula, federal food date labels generally indicate quality rather than safety. Phrases such as “sell by,” “best if used by,” and “use by” can therefore work differently from the regulated use-by meaning in New Zealand and Australia.


US readers should follow the package instructions, safe-storage guidance, and any applicable state or local rules. Never apply one country’s date-label rule automatically to food sold in another.


Frequently Asked Questions

Can you eat food after its best-before date?

Often, yes. In New Zealand and Australia, a best-before date concerns quality. Food may still be safe after the date if it was stored correctly, the packaging is sound, and there are no signs of spoilage. Follow any after-opening instructions as well.

In New Zealand and Australia, no. A use-by date is about safety, and food should not be eaten after that date even if it looks or smells normal.

Plan to freeze suitable food before the use-by date and follow the label’s freezing instructions. New Zealand Food Safety recommends freezing food before its best-before or use-by date, then handling it safely when thawing.

Does the date still apply after a package is opened?

Not by itself. Instructions such as “refrigerate after opening” or “use within three days” may create a shorter timeframe. Write down the date you opened the product and follow the package guidance.

A pantry-management app can help you record dates, see which items need using first, connect those items to meal plans, and avoid buying duplicates. It does not replace the package label or official food-safety advice.



Use the Date, Not Just the Food

The simplest way to remember the difference is this: use by is about safety; best before is about quality. Once that rule is clear, the next step is visibility. Track the foods that are easy to forget, bring the nearest dates forward, and let those ingredients shape at least one meal each week.


Try Shelve to keep your pantry, meal plan, recipes, expiry awareness, and grocery list connected, so more of the food you buy has a plan before its date arrives.
