The Most Common Food Date Labels Explained
1. “Best By” or “Best Before”
This date is about quality, not safety.
- Indicates when the food is at its best flavor or texture
- Food is often still safe to eat after this date if stored properly
- Common on dry goods, snacks, and canned foods
Think of it as a suggestion, not a strict deadline.
2. “Use By”
This is the most important date to follow.
- Often found on perishable foods like dairy, deli items, and ready-to-eat meals
- Refers to food safety, not just quality
- Food should not be consumed after this date
When you see “Use by,” it’s best to take it seriously.
3. “Sell By”
This date is meant for stores, not consumers.
- Helps retailers know how long to display products
- Food is usually safe for days or even weeks after this date if stored correctly
Many people mistake this for an expiration date—but it isn’t.
Why Food Doesn’t Instantly Go Bad After the Date
Expiration dates don’t mean food magically spoils overnight. Storage conditions matter just as much as the printed label.
Food can last longer if:
- It’s kept refrigerated or frozen properly
- Packaging is unopened and intact
- It shows no signs of spoilage
That’s why using your senses is still important.
Signs Food Has Actually Gone Bad
Regardless of the date, throw food away if you notice:
- A strong sour or rotten smell
- Visible mold
- Slimy or sticky texture
- Unusual color changes
When in doubt, it’s always safer to discard it.
Reducing Food Waste Safely
Understanding expiration labels can help save money and reduce waste:
- Check dates when shopping and rotate older items forward at home
- Freeze foods before their “Use by” date if you won’t eat them in time
- Plan meals around foods that need to be used first
Smart planning keeps food safe and cuts down on unnecessary waste.
Final Thoughts
Food expiration dates are guidelines—not all of them are strict safety warnings. Knowing the difference between “Best by,” “Use by,” and “Sell by” helps you make better decisions in the kitchen.
When you combine label knowledge with proper storage and common sense, you can protect your health, save money, and waste less food—all at the same time.
