Are Expiration Dates Required on Food Products?
Short answer
Expiration dates are generally not required by federal law on most food products in the U.S., but many manufacturers include them voluntarily to guide consumers on food quality and safety. These dates help indicate when food is freshest, though products can sometimes remain safe to eat beyond the printed date if stored properly.
What Are Expiration Dates on Food Products?
Expiration dates are printed labels on food packaging that indicate when a product is expected to maintain its best quality or be safely consumed. Common phrases include "Use By," "Best Before," "Sell By," and "Expires On." These labels help consumers understand how long food is likely to be fresh or safe. For instance, milk often has a "Use By" date to suggest when it should be consumed, while canned goods may have a "Best Before" date that relates more to taste than safety.
It’s important to remember these dates are often about quality rather than a strict safety deadline. For example, a yogurt labeled with a “Use By” date of July 10 might still be safe to eat a day or two later if it smells and looks normal. However, deli meats labeled with a “Use By” date should be consumed by that date due to their higher risk of spoilage.
Since food producers use different terms and standards, expiration date labeling can vary widely between products. Some foods, like baby formula, legally require expiration dates due to safety and nutrition concerns. Others rely on voluntary labeling to help consumers decide when to use or discard products.
Are Expiration Dates Required by Law in the U.S.?
In the U.S., there is no federal law requiring expiration dates on most food products. Regulatory agencies like the Food and Drug Administration and the United States Department of Agriculture (USDA) oversee food safety but do not mandate expiration date labeling except in limited cases. For example, infant formula must carry an expiration date to guarantee safety and nutritional quality.
Some individual states may have their own rules about expiration dates, but these vary and do not form a unified system. Because of this, expiration dates primarily serve as voluntary guidelines set by manufacturers to protect consumers and help retailers manage stock.
This means not every food product will have an expiration date, and even when present, the format and wording can differ. Many shelf-stable foods such as dried pasta, rice, or canned vegetables may not show expiration dates because these products typically stay safe for long periods if stored correctly.
How Do Expiration Dates Work? A Hypothetical Example
Imagine buying a carton of milk labeled "Sell By May 1." The "Sell By" date is mainly intended for the store, indicating when the product should be sold or removed. For consumers, the milk will often remain safe to drink for several days after this date if it has been continuously refrigerated at or below 40°F.
Here’s a step-by-step example of how you might use expiration dates:
- Check the date before purchase. Avoid buying milk that is close to or past the "Sell By" date unless you plan to use it immediately.
- Store the milk properly. Keep it refrigerated at or below 40°F to slow bacterial growth.
- Use the milk by the "Use By" or a few days after the "Sell By" date. If the label has a “Use By” date, follow it strictly for safety.
- Use your senses to evaluate. Before drinking, smell the milk and look for curdling or discoloration.
- Discard if you notice spoilage signs. If it smells sour or looks off, throw it out regardless of the date.
This example shows that expiration dates work alongside proper storage and sensory checks to help you decide when food is safe to consume. They are not absolute cutoffs but valuable guidelines.
Why Do Expiration Dates Matter to You?
Expiration dates matter because they help protect your health and reduce food waste. Consuming food past its safe period can lead to foodborne illnesses, which may cause symptoms like upset stomach, vomiting, or more serious infections. For instance, eating spoiled dairy or meat can result in discomfort or even hospitalization.
Additionally, expiration dates help you plan meals and grocery shopping. By knowing when foods reach their peak freshness or safety limits, you can prioritize using those items first, preventing spoilage and waste. This also helps you save money by not throwing away food prematurely.
People with weakened immune systems, such as young children, older adults, or those with certain medical conditions, should pay closer attention to expiration dates because their bodies may not fight infections as effectively. For these groups, following expiration dates carefully is especially important.
Understanding expiration dates empowers you to take control of food safety in your home, helps avoid unnecessary waste, and keeps your family healthy.
What Are Related Terms People Often Mix Up with Expiration Dates?
Many people confuse expiration dates with other common food date labels, which can lead to misinterpretation:
| Term | What It Means | Common Example |
|---|---|---|
| Sell By | Date by which the store should sell the product; not a safety date | Milk carton “Sell By July 10” |
| Best Before | Date indicating when food is at best quality, not necessarily unsafe afterward | Canned soup “Best Before Dec” |
| Use By | Date recommended for last safe consumption, often on perishables | Yogurt “Use By May 5” |
| Expiration | Date after which the product should not be eaten for safety | Infant formula “Expires July” |
Knowing these distinctions helps you understand which dates relate to safety and which relate to quality or inventory management. For example, a “Sell By” date tells the store when to remove the product, but the food may still be good for days after. A “Best Before” date means the food might lose flavor or texture but is not necessarily unsafe.
When shopping or organizing your pantry, paying attention to these terms and their meanings helps reduce confusion and improves food safety practices.
What Should You Do When You See an Expiration Date on Food?
When you find an expiration date on a food product, here are concrete steps to follow:
- Check the date before buying. If the product is past its expiration or close to it, consider whether you can use it before it spoils.
- Store the item correctly. Follow label instructions—refrigerate perishables promptly, keep dry goods in cool, dry places.
- Plan your meals around the dates. Use foods nearing expiration first to avoid waste.
- Inspect the food before use. Look for mold, discoloration, or strange odors.
- When unsure, don’t risk it. If the food seems off, discard it to avoid illness.
- Label leftovers with the date. Use masking tape or a marker to note when you stored them to keep track.
- Freeze foods if not using immediately. Many perishables can be frozen before the expiration date to extend shelf life.
For example, if you buy chicken with a "Use By" date three days away but won’t cook it until day four, freeze it immediately to keep it safe. When ready to use, thaw in the refrigerator and cook promptly.
These practical steps help you use expiration dates effectively, reducing both health risks and food waste.

Frequently asked questions
Are expiration dates the same for all types of food?
No, expiration dates vary by food type and how quickly items spoil. Perishables like dairy have clearer “Use By” dates, while shelf-stable items may have “Best Before” dates focused on quality rather than safety.
Can food still be safe after its expiration date?
Sometimes, yes. Many foods remain safe shortly after the date if stored properly and if there are no signs of spoilage. Use your senses and judgment to decide, but when in doubt, discard the food.
Why do some foods not have expiration dates?
Expiration dates are not required for most foods, especially dry or canned goods that remain safe for long periods. Manufacturers may choose not to include a date because the product’s shelf life is very long.
How should I store food to maximize safety past expiration dates?
Keep perishables refrigerated or frozen as instructed on the packaging. Store dry goods in cool, dry places. Avoid temperature fluctuations and seal food tightly to prevent spoilage.
What if I buy food close to or past its expiration date?
Only buy such products if you plan to use them immediately. Check them carefully for spoilage signs before use. For perishable items, it’s safer to avoid purchasing foods past their “Use By” dates.
