Best Before Date vs. Expiry Date

Best Before Date vs. Expiry Date: What’s the Difference and Why It Matters?

Have you ever thrown away food simply because the date on the packaging had passed? Based on our experience working with food and beverage manufacturers, this is one of the most common misconceptions among consumers and sometimes even among business owners. Many people assume that Best Before Date and Expiry Date have the same meaning, even though they serve completely different purposes. In this guide, we’ll explain the differences between Best Before Date and Expiry Date, when products are still safe to consume, how manufacturers determine these dates, why accurate date coding is essential, practical examples across industries, and recommendations for choosing the right coding solution.

Best Before Date vs. Expiry Date: What Is the Real Difference?

The main difference is simple:

• Best Before Date indicates the period during which a product maintains its best quality.
• Expiry Date indicates the last date a product is considered safe to consume.

This distinction is recognized by international food labeling standards, including the Codex Alimentarius developed by the FAO and WHO, which recommend different types of date markings depending on the product’s characteristics and food safety risks.

From our experience supporting food manufacturers with coding and marking systems, we have seen that misunderstanding these labels often leads to unnecessary product waste. Many products marked with a Best Before Date are discarded even though they remain perfectly safe to eat.

Best Before Date vs. Expiry Date Comparison

Aspect	Best Before Date	Expiry Date
Purpose	Indicates peak product quality	Indicates product safety limit
Product Condition After Date	Usually still safe if stored properly	Should not be consumed
Typical Products	Coffee, biscuits, rice, canned food, frozen food	Infant formula, medicines, medical nutrition
Quality Changes	Flavor, aroma, texture, appearance	Safety risks may increase
Consumer Action	Inspect before consuming	Dispose after the expiry date

According to the European Commission, better consumer understanding of date labels could significantly reduce food waste across the supply chain.

Why Do Consumers Often Confuse These Two Dates?

In our opinion, the biggest reason is that both dates look similar on product packaging.

Many consumers only notice the printed date without paying attention to the wording that appears before it. Labels such as Best Before, Use By, Expiry Date, or Expiration Date are often interpreted as having the same meaning.

We’ve also observed this issue while helping customers improve product labeling. Clearer date printing, better packaging design, and consumer education can substantially reduce misunderstandings.

Can You Eat Food After the Best Before Date?

In many situations, yes.

Unlike an Expiry Date, a Best Before Date does not automatically mean the product has become unsafe. Instead, it means the manufacturer can no longer guarantee the product’s optimal quality.

For example:

• A package of pasta may still be perfectly safe several months after its Best Before Date.
• Coffee may lose some aroma but remain safe to drink.
• Crackers may become less crispy without becoming unsafe.

Before consuming any product, we recommend checking:

• Packaging integrity
• Odor
• Appearance
• Texture
• Storage history

If any signs of spoilage are present, the product should be discarded regardless of the printed date.

How Manufacturers Determine Best Before and Expiry Dates

Manufacturers don’t estimate these dates—they validate them through testing.

Food companies conduct Shelf Life Testing, which evaluates:

• Microbiological stability
• Moisture content
• Flavor retention
• Color stability
• Nutritional quality
• Packaging performance
• Storage conditions

Based on our experience working with food production facilities, companies also perform validation under different environmental conditions to ensure the printed date accurately reflects the product’s expected shelf life.

This scientific approach helps manufacturers comply with food safety regulations while maintaining consistent product quality.

Why Accurate Date Coding Matters

Determining the correct date is only half of the process.

Equally important is ensuring the date can be clearly read throughout manufacturing, transportation, warehousing, and retail distribution.

We have encountered production lines where perfectly safe products were rejected simply because the printed date was blurred or incomplete.

Today’s manufacturers commonly use:

• Continuous Inkjet (CIJ)
• Thermal Inkjet (TIJ)
• Laser Marking Systems

These technologies print:

• Best Before Date
• Expiry Date
• Batch Number
• Lot Number
• Barcode
• QR Code

Our recommendation is to choose a coding system that matches production speed while producing durable, high-contrast prints.

Common Mistakes Businesses Should Avoid

Based on projects we’ve handled, these are the most common mistakes:

• Using low-quality printers that produce faded dates.
• Printing dates too close to package edges.
• Failing to inspect printed codes during production.
• Confusing Best Before and Expiry labels.
• Not validating shelf life after packaging changes.

Preventing these issues improves compliance, reduces product recalls, and minimizes unnecessary waste.

Our Recommendations for Food Manufacturers

If you’re producing food or beverages, don’t focus only on assigning the correct date.

We recommend investing in:

• Reliable coding equipment.
• High-resolution printing technology.
• Automated print inspection systems.
• Shelf life validation.
• Staff training on date labeling requirements.

In our experience, businesses that treat date coding as part of their quality assurance process experience fewer customer complaints and smoother distribution operations.

Frequently Asked Questions

Is Best Before Date the same as Expiry Date?

No. A Best Before Date refers to product quality, while an Expiry Date refers to product safety.

Can food still be eaten after the Best Before Date?

Often yes, provided it has been stored correctly and shows no signs of spoilage.

Why do medicines use Expiry Dates instead of Best Before Dates?

Medicines may lose effectiveness or become unsafe after the expiry date, making product safety the primary concern.

How do manufacturers determine these dates?

Manufacturers conduct Shelf Life Testing and scientific stability studies before assigning either a Best Before Date or an Expiry Date.

Why is date coding important?

Clear date coding helps manufacturers comply with regulations, improves traceability, prevents distribution errors, and provides consumers with accurate product information.

Conclusion

Although they are often mistaken for one another, Best Before Date and Expiry Date serve different purposes. Best Before focuses on product quality, while Expiry Date relates directly to food safety. Based on our experience in the coding and marking industry, accurate date labeling is just as important as determining the correct date itself. Investing in reliable coding technology, validated shelf life testing, and clear packaging helps manufacturers protect consumers, comply with regulations, and strengthen brand trust.
