Examples of Expiration Dates on Products
Short answer
Expiration dates on products show the last day a product is guaranteed to be safe or at its best quality when stored properly. For example, a milk carton might say “Use By April 10,” meaning it should be consumed by that date for safety. Understanding these dates helps prevent illness, reduce waste, and make smarter choices about food and product use.
What Are Expiration Dates on Products?
Expiration dates are labels on food and other perishable products that indicate how long the item is expected to remain safe to consume or use or when it is at its peak quality. These dates help you decide whether to eat or throw out a product. Common terms you might see include:
- Use By: The last date recommended for safety. After this, the product may not be safe to consume.
- Best Before / Best If Used By: Indicates when the product will have the best flavor or texture but may still be safe afterward.
- Sell By: Directed at retailers for inventory management; not a safety date.
- Freeze By: The recommended date to freeze a product for maintaining quality.
Expiration dates are based on testing under specific storage conditions, such as refrigeration or room temperature. They are guidelines, not guarantees. For example, canned food may remain safe after its “Best Before” date if the can is intact and stored properly, but raw poultry should be used by the “Use By” date for safety. Recognizing these differences helps you make better decisions about food safety and freshness.
How Do Expiration Dates Work? (With a Detailed Example)
Expiration dates estimate how long a product stays safe and fresh when stored as recommended. Take yogurt as an example. If a container shows “Use By April 10,” it means the manufacturer guarantees safety and quality if refrigerated properly and consumed by that date.
Suppose you buy this yogurt on April 5 and keep it consistently refrigerated at or below 40°F. You should plan to eat it by April 10. Eating it after that date increases the risk of spoilage or harmful bacteria growth. If you open the container, the risk grows faster. Signs the yogurt has gone bad include a sour smell, mold, or a lumpy texture.
Another example is a can of beans with a “Best If Used By” date. This date indicates peak quality but the food may remain safe well past this date if the can is undamaged and stored at room temperature. However, if you notice dents or rust on the can, it is safer to discard it regardless of the date.
This system helps you plan meals, avoid food waste, and prevent foodborne illness. It also assists stores in rotating stock and helps consumers understand safety and quality timelines.
Why Do Expiration Dates Matter to You?
Expiration dates matter because they protect your health and can help save money. Consuming products past their safe dates may cause foodborne illnesses, with symptoms like stomach cramps, vomiting, or diarrhea, especially from dairy, meat, or seafood.
Using expiration dates helps you avoid food waste by encouraging you to use items before they spoil. For example, if you buy several dairy products, checking their expiration dates helps you use those expiring soon first. This reduces throwing away food that went bad because you forgot about it.
These dates also provide peace of mind. For example, baby formula or medications require strict adherence to expiration dates to ensure safety and effectiveness.
Not all expiration dates mean a product becomes unsafe immediately after the date. Some foods, like dry pasta or canned goods, may remain safe beyond their dates if stored properly. However, perishable items such as fresh meat should never be consumed past their “Use By” date. Knowing when to trust the date and when to check for spoilage signs is essential for safety.
What Are Common Terms Confused with Expiration Dates?
Many people mix up expiration dates with other labels that serve different purposes. Understanding the differences can prevent mistakes:
- Sell By: A date intended for stores to know how long to display a product. It is not a safety date. For example, milk can be safe to drink several days after the “Sell By” date if kept cold.
- Best Before / Best If Used By: Indicates when a product is at its best quality but not necessarily unsafe after this date.
- Use By: The last date recommended for safety, especially on perishable foods.
- Freeze By: A date that suggests when to freeze a product to maintain its quality, but not a safety deadline.
For example, eggs often have a “Sell By” date, meaning stores should sell them by that day, but if kept refrigerated, eggs can remain safe and fresh for several weeks beyond that date. On the other hand, “Use By” dates on deli meats or fresh poultry are safety deadlines that should be followed carefully.
Understanding these terms helps you better manage food safety and avoid unnecessary waste.
What Are Examples of Expiration Dates on Common Foods?
Below is a table of common food products with typical expiration date labels and their meanings:
| Product | Common Date Label | Meaning | Storage Tips |
|---|---|---|---|
| Milk | Use By | Safe to consume until this date if refrigerated | Store at or below 40°F |
| Bread | Best Before | Peak quality until this date; safe but may stale after | Store in a cool, dry place or freeze |
| Canned goods | Best If Used By | Quality peak; may be safe long after if sealed | Store in a cool, dry pantry |
| Baby formula | Use By | Safety and nutrition guaranteed until this date | Store unopened as directed |
| Meat and poultry | Use By | Safety deadline; do not consume after this date | Refrigerate or freeze promptly |
| Eggs | Sell By | Store guideline; safe beyond this if refrigerated | Keep refrigerated at or below 40°F |
For example, if chicken has a “Use By” date of May 15, cook or freeze it before then. If frozen by May 14, it can remain safe for months. Bread with a “Best Before” date may still be edible days afterward but could be stale or dry; check for mold or odors before eating.
These examples illustrate how expiration dates vary by product and help you decide how to store and use foods safely.
What Should You Do When You See an Expiration Date?
When you encounter an expiration date, follow these steps to keep food safe and reduce waste:
- Check dates before buying: Choose products with later expiration dates when shopping to ensure freshness.
- Organize your storage: Arrange foods so those with earlier expiration dates are in front (“first in, first out”).
- Follow storage instructions: Keep refrigerated items at or below 40°F and frozen items at 0°F or lower.
- Inspect before use: Look for signs of spoilage such as off smells, mold, discoloration, or unusual texture.
- Use exact wording as a guide: “Use By” means consume by that date. “Best Before” allows some flexibility but use caution.
- Discard if unsure: If a product is past its “Use By” date or shows spoilage signs, throw it out to avoid illness.
For example, if milk says “Use By April 10” and today is April 11, do not drink it even if it smells okay. If a can of soup is past the “Best If Used By” date by a few weeks but the can is intact and the soup looks and smells normal, it may still be safe.
Following these steps helps you balance safety and food waste.
How Do Expiration Date Laws and Regulations Affect You?
In the U.S., there is no single federal law requiring expiration dates on all food products. Labeling rules vary by state and product type. Some products, like baby formula, have federally regulated expiration dates to ensure safety and nutrition.
Manufacturers often include expiration dates voluntarily to meet consumer expectations and comply with state laws. Retailers use dates such as “Sell By” to manage stock and reduce waste.
Because these rules vary, it’s helpful to check your state’s health department or consumer protection agency for local guidance, especially for perishable foods.
Medications and some cosmetics have strict expiration dates regulated by the FDA because their safety and effectiveness decline after those dates. Never use expired medications.
Knowing the legal context helps you interpret expiration dates correctly and make safe choices.

Frequently asked questions
Can I eat food after the expiration date?
It depends on the label and product type. Perishable items with “Use By” dates should not be eaten after that date. Foods with “Best Before” dates may be safe a short time after if properly stored and showing no signs of spoilage.
What is the difference between “Use By” and “Best Before”?
“Use By” is a safety deadline, especially for perishable foods. “Best Before” indicates peak quality but not necessarily safety after the date.
Do all products have expiration dates?
No. Many shelf-stable products like sugar, rice, or dried pasta do not have expiration dates because they last long if stored properly.
How should I store products to maximize their shelf life?
Follow instructions on packaging. Keep refrigerated items at or below 40°F, freeze for longer storage, and store dry goods in cool, dry places.
What if an expired product looks and smells fine?
For perishable foods with “Use By” dates, it is safer to discard them even if they seem okay because harmful bacteria may not be detectable.
Are expiration date rules the same in every state?
No. Labeling laws and requirements vary by state and product. Check local health department guidelines for specifics.
