Food labels can be confusing. We often see “Best By,” “Use By,” and “Sell By” stamped on packaging, yet many of us are unsure of what they truly mean. Misunderstanding these labels leads to unnecessary food waste, health risks, and confusion in the kitchen. To make smarter choices, we need a clear understanding of how these dates differ and how they impact food safety and quality.
The Importance of Understanding Food Expiration Dates
Every year, millions of tons of food are thrown away simply because people misread or misinterpret expiration dates. While some labels indicate food safety, others only suggest food quality. By knowing the difference, we can avoid waste and protect our health at the same time.
Expiration dates are not always strict rules—they are guidelines set by manufacturers to ensure food is consumed at its best. But, food can often be safe and tasty even after the printed date. Understanding which labels matter most helps us make informed decisions.
What Does “Best By” Mean?
The label “Best By” is about quality, not safety.
- Meaning: The manufacturer guarantees that the product will taste its best and have the right texture, flavor, and freshness until this date.
- Examples: Chips, canned goods, dry pasta, cereal, and snacks.
- After the Date: The food may still be safe to eat but could lose its crunchiness, flavor, or aroma.
For example, a box of crackers might taste less crispy after the “Best By” date, but it is not dangerous unless there are signs of spoilage such as mold or a bad smell.
What Does “Use By” Mean?
The label “Use By” is the most important for food safety.
- Meaning: This is the last date recommended by the manufacturer for the product to be consumed safely.
- Examples: Fresh meat, poultry, fish, baby formula, and some dairy products.
- After the Date: Eating food past the “Use By” date can increase the risk of foodborne illness.
Unlike “Best By,” the “Use By” date is strict. For foods that spoil quickly, such as raw chicken or fresh milk, we should never ignore this date.
What Does “Sell By” Mean?
The label “Sell By” is meant for stores, not consumers.
- Meaning: It tells retailers how long to display the product for sale. After this date, the store should remove it from shelves.
- Examples: Milk, eggs, cheese, and packaged fresh foods.
- After the Date: Products are often safe for a few days beyond the “Sell By” date if stored properly at home.
For instance, milk with a “Sell By” date of March 5 may still be safe to drink until March 10, provided it has been refrigerated.
How Long Is Food Safe After the Printed Date?
Many foods remain safe even after the printed dates. Here are general guidelines:
- Milk: 5–7 days past the “Sell By” date if refrigerated.
- Eggs: 3–5 weeks after purchase, even if the “Sell By” date has passed.
- Canned Goods: Up to 1–2 years if stored in a cool, dry place.
- Dry Pasta and Rice: 1–2 years past the “Best By” date if kept airtight.
- Frozen Foods: Safe indefinitely, though quality may decline after several months.
Signs of Spoilage You Should Never Ignore
Even if a product is within the date range, always check for signs of spoilage. If you notice any of the following, it is better to throw the food away:
- Unpleasant or sour odor
- Mold or unusual spots
- Slimy or sticky texture
- Bulging cans or broken seals
- Bitter or “off” taste
Our senses are often the best tools for checking food safety.
Why Food Date Labels Are Confusing
Food date labels are not standardized worldwide. In many countries, manufacturers set the dates without strict government regulations. This inconsistency is what causes confusion among consumers.
- In the U.S.: The FDA requires only infant formula to have strict “Use By” dates. For most other products, dates are about quality.
- In the EU: “Use By” is for highly perishable foods, while “Best Before” is for products that stay safe for longer.
- In Africa and Asia: Many countries follow mixed systems, often influenced by either U.S. or European standards.
This lack of global standardization makes it harder for people to know which foods are safe to eat.
How to Store Food to Extend Its Life
Proper storage can make a big difference in how long food lasts beyond the printed date.
Refrigeration Tips:
- Store milk and juices on shelves, not in the door, where temperatures fluctuate.
- Keep raw meat on the bottom shelf to prevent cross-contamination.
- Use airtight containers for leftovers.
Freezing Tips:
- Freeze meat if you cannot use it within a few days of purchase.
- Label and date frozen foods to track storage time.
- Use freezer bags to prevent freezer burn.
Dry Storage Tips:
- Store rice, flour, and pasta in sealed containers.
- Keep canned goods in a cool, dark place.
- Rotate stock—use older products first.
How Expiration Dates Affect Food Waste
Misunderstanding labels contributes to massive food waste. According to global studies:
- About 30–40% of food produced is wasted.
- A large part of this waste happens in households because people throw away food that is still safe to eat.
By learning what expiration dates really mean, we can reduce waste, save money, and protect the environment.
Common Foods That Last Longer Than You Think
- Honey: Can last forever if stored properly.
- Salt and Sugar: Indefinite shelf life when kept dry.
- Vinegar: Does not expire, though quality may change over time.
- Hard Cheeses (like Parmesan): Can last months if mold is cut off.
- Dried Beans and Lentils: Safe to eat for years, though they may take longer to cook.
Practical Tips for Using Food Dates Wisely
- Understand the Label: Know the difference between “Best By,” “Use By,” and “Sell By.”
- Trust Your Senses: Smell, look, and taste before throwing food away.
- Practice FIFO (First In, First Out): Use older food before newer purchases.
- Freeze to Extend Life: Freeze items nearing their “Use By” date if you cannot consume them.
- Plan Your Meals: Avoid buying more than you can use within a safe timeframe.
Conclusion
Understanding food expiration dates—Best By, Use By, and Sell By—is essential for both safety and reducing waste. While “Use By” dates should always be respected for perishable items, “Best By” and “Sell By” often relate more to quality than safety. By learning how to read labels, store food properly, and trust our senses, we can enjoy food longer, save money, and contribute to a more sustainable world.
