Hey! Don’t throw away that food just yet. Please, check whether you have an expiry date or best before date before you conclude it’s no longer safe to eat. Do you even know the differences between Expiry, Best Before, and Use-By dates? Even if you think you do, you might be surprised by what we have to share in this article. Therefore, we invite you to continue reading.
When it comes to food safety and quality, dates printed on packaging play a critical role. These dates—often referred to as expiry dates, best-before dates, and use-by dates—provide consumers with essential information about food products’ freshness, safety, and optimal consumption period. Understanding the differences between these dates can help you make better decisions about food storage, consumption, and waste. This article delves into the definitions, significance, and best practices related to these dates, helping you ensure your food is safe and enjoyable.

What’s the difference between Expiry Date and Best Before Date?

Expiry Dates
Definition and Significance: An expiry date is the final date a food product is considered safe to consume. After this date, the manufacturer cannot guarantee the product’s safety due to potential degradation of ingredients or contamination. Expiry dates are particularly crucial for perishable items like dairy products, meats, and certain pharmaceuticals.
Safety Concerns: Consuming products past their expiry date can pose health risks, including foodborne illnesses. The ingredients in expired products may have undergone chemical changes, leading to spoilage, the growth of harmful bacteria, or loss of nutritional value.
Best Practices:
- Regular Check: Routinely check the expiry dates on food items in your pantry and refrigerator.
- First In, First Out (FIFO): Use older products before newer ones to minimize waste.
- Proper Storage: Follow storage instructions to prolong the shelf life of products. For instance, refrigerate perishable items promptly after purchase.

Best Before Dates
Definition and Significance:A best before date indicates the period during which the product is expected to retain its best quality, such as flavor, texture, and nutritional value. Unlike expiry dates, best before dates do not necessarily relate to food safety. This date is commonly found in products like canned goods, dry foods, and frozen items.
Quality Considerations: After the best-before date, the product may still be safe to consume, but its quality might have diminished. For example, biscuits might become stale, and canned vegetables may lose some of their crispness or flavor.
Best Practices:
- Sensory Evaluation: Use your senses—smell, taste, and visual inspection—to assess the quality of a product past its best-before date.
- Storage Conditions: Proper storage can extend the quality of products. Keep dry foods in cool and dry places and follow freezing guidelines for frozen goods.
What about Use-By Dates?
Definition and Significance: A use-by date is a strict indicator of the last date the product is safe to consume. This data is used primarily for highly perishable items like fresh meats, dairy products, and ready-to-eat salads. Unlike best-before dates, use-by dates are closely tied to food safety.
Safety Concerns: Consuming products past their use-by date can lead to severe health risks. These items are prone to bacterial growth, and their safety cannot be assured beyond the use-by date.
Best Practices:
- Adherence to Dates: Strictly adhere to use-by dates and avoid consuming products past this date.
- Proper Refrigeration: Store perishable items at the recommended temperatures to maintain their safety and quality until the use-by date.
- Cooking Instructions: Follow cooking instructions carefully to ensure that any harmful bacteria are destroyed.
Key Differences and Misconceptions
Differences:
- Safety vs. Quality: Expiry and use-by dates are primarily concerned with safety, whereas best-before dates focus on quality.
- Perishability: Use-by dates are for highly perishable items, while best-before dates are for less perishable goods.
- Regulatory Aspects: Regulations around these dates can vary by country, affecting how manufacturers label their products.
Common Misconceptions:
- Universal Meaning: Consumers often confuse expiry dates with best-before dates, assuming both indicate safety. Understanding the distinction is crucial for informed decision-making.
- Waste Reduction: Misinterpreting these dates contributes to unnecessary food waste. Recognizing that best-before dates pertain to quality can help reduce discarding perfectly edible food.
Regulatory and Industry Perspectives
Regulations: Regulatory bodies, such as the USDA in the United States, provide guidelines for food labeling to ensure consumer safety. According to the USDA, while federal regulations do not require most foods to have a date, many manufacturers choose to include them to help consumers make informed decisions and comply with state-level requirements.
Industry Practices: Manufacturers determine these dates based on product testing, considering factors like ingredient stability, packaging, and storage conditions. They aim to provide dates that ensure consumers experience the product at its best while also ensuring safety.
Practical Tips for Consumers
Reading Labels:
- Identify Date Types: Learn to distinguish between expiry, best before, and use-by dates on different products.
- Understand Storage Instructions: Follow any additional storage instructions provided on the label to maintain product quality and safety.
Minimizing Waste:
- Plan Meals: Plan your meals and grocery shopping to use items before they expire or reach their best-before date.
- Use Leftovers: Incorporate leftovers into new meals to avoid wasting food that is still safe and of good quality.
Food Donations:
- Check Dates: When donating food, ensure that items are within their best before or use-by dates to maintain safety and quality for recipients.
Conclusion
Understanding the distinctions between expiry dates, best-before dates, and use-by dates is essential for ensuring food safety and minimizing waste. By paying attention to these dates, following proper storage guidelines, and using sensory evaluation, consumers can enjoy their food at its best while also contributing to a reduction in food waste. Educating yourself and others about these dates can lead to healthier, safer, and more sustainable consumption habits.
