What You Should Know About Expiration Dates Law
Short answer
Expiration dates law governs how food products are labeled with dates indicating freshness, quality, or safety, but in the U.S., there is no single federal law requiring expiration dates on all foods. These laws vary by state and product type, mainly aiming to inform consumers and reduce foodborne illness, helping you make safer, more informed food choices without unnecessary waste.
What Are Expiration Dates Law in Plain Words?
Expiration dates law refers to government rules about putting dates on food packaging to tell consumers when a product is best used or safe to eat. These laws help protect public health by guiding consumers and stores on how to handle perishable foods. In the U.S., no single federal mandate requires expiration dates on all foods; instead, individual states and federal agencies set guidelines for specific products.
For example, dairy products often have expiration or “use by” dates because they spoil quickly, while canned goods might only have “best before” dates indicating quality rather than safety. These laws require food manufacturers to label foods clearly so consumers understand when a product should be consumed to avoid health risks. However, the exact wording—like “sell by,” “use by,” or “best before”—can have different legal meanings depending on the state and product category.
Expiration dates laws are designed to balance consumer safety with reducing food waste. They do not always mean a food is unsafe immediately after the date, but they signal when the product might no longer be at peak freshness or safety. This informs consumers about how long to keep food and when to discard it.
How Does Expiration Dates Law Work? A Clear Example
Expiration dates laws work by setting rules for how and when foods must be labeled with dates, which in turn affect how stores sell and consumers use those products. For example, suppose you buy a package of chicken labeled “use by April 20.” The law in your state might require the store to remove this chicken from shelves after April 20 to ensure freshness for customers.
Once you bring the chicken home, the “use by” date means the manufacturer guarantees quality and safety up to that day. Eating it after April 20 might increase the risk of foodborne illness, especially if it is not stored properly. If you open the chicken on April 21 and it smells sour or looks slimy, the law’s advice aligns with your senses: discard it.
In contrast, a “sell by” date on a carton of eggs might only tell the store when to stop selling them, but the eggs could still be safe for several days after that date if refrigerated properly. This flexibility is common because expiration dates laws do not always enforce a hard discard deadline but focus on guiding consumers and retailers.
This example shows how expiration dates laws guide safe food handling and reduce risks, while also allowing consumers to make informed choices based on storage and sensory checks.
Why Do Expiration Dates Laws Matter for You?
Expiration dates laws matter because they help prevent foodborne illness and reduce food waste, two key concerns for every household. Knowing what these dates mean can protect your health by alerting you to when foods might spoil or become unsafe, especially for vulnerable groups like children, elderly people, or those with weakened immune systems.
For example, if you buy yogurt labeled “best before June 10,” eating it well past that date could cause digestive upset if the yogurt has spoiled. Following expiration dates laws means you understand that “best before” dates relate to quality, not safety, so you might use your senses to decide if it’s okay to eat.
At the same time, these laws help you avoid throwing out food prematurely. For instance, a loaf of bread with a “sell by” date from last week might still be safe to eat if stored correctly and free from mold. By understanding expiration dates laws, you save money and help reduce food waste — a major environmental and economic issue.
Additionally, expiration dates laws encourage manufacturers and stores to maintain food safety standards, giving consumers peace of mind about their purchases. They create a system that balances safety with practicality, allowing flexibility for consumers to decide based on proper food storage and condition.
What Are the Different Terms on Food Labels and How Do They Differ?
Many terms appear on food packaging relating to dates, and these can be confusing because they mean different things. Here are the common labels and their general meanings:
| Term | Meaning | Example Use |
|---|---|---|
| Sell By | The date by which a store should sell the product; not a safety deadline for consumers | Milk carton sold by April 15 |
| Use By | The last date recommended for safe use to ensure safety and quality | Perishable food like deli meat |
| Best Before | Indicates peak quality date; food may still be safe after but might lose freshness | Dry cereal, canned goods |
| Expiration Date | The last date manufacturer guarantees safety and quality; varies by product | Baby formula, some medications |
Using exact wording when reading labels helps consumers understand safety risks. For example, if a package says “use by April 10,” that means it should ideally be consumed by then, while “best before” means the product might still be edible after that date but quality may decline. “Sell by” dates mostly guide stores rather than consumers.
This difference impacts how you manage your groceries. For instance, you can often use “best before” foods beyond the date after a sensory check, but “use by” foods should generally be consumed by the date for safety.
What Are Federal and State Roles in Expiration Dates Law?
Expiration dates laws in the United States are managed by a combination of federal guidelines and state regulations. The Food and Drug Administration and U.S. Department of Agriculture (USDA) provide voluntary guidelines and oversee labeling for many food products. However, they do not require mandatory expiration dates on all foods.
States have the power to set their own rules, which often focus on perishable foods like dairy, eggs, and meat. For example, some states require dairy products to have expiration dates and require stores to remove products after those dates, while others do not. This means expiration date laws can vary significantly depending on where you live.
Because of this variation, consumers should check their state health department or agriculture websites for local regulations. Retailers often follow these local rules strictly. For example, a grocery store in one state may pull milk from shelves on its expiration date, while a store in another state may allow several extra days for sale.
The combined federal and state framework aims to protect consumers while allowing flexibility for different food types and local conditions. Understanding this split helps you be more aware of how expiration dates affect your food purchases and storage.
How Can You Use Expiration Dates Laws to Make Safer Food Choices?
You can use expiration dates laws to help keep your food safe and reduce waste by following practical steps:
- Read Labels Carefully: Pay attention to whether the label says “use by,” “sell by,” or “best before” and understand what each means for safety and quality.
- Check Storage Instructions: Store foods as directed (e.g., refrigerate after opening) to maximize shelf life and safety.
- Use Your Senses: Smell, look, and taste foods when they are close to or just past the date to decide if they are still safe.
- Rotate Foods in Your Pantry: Use older items first to avoid food spoiling before you consume it.
- Plan Purchases Wisely: Buy only what you can consume within the recommended time frames.
- Dispose Responsibly: Throw away products showing signs of spoilage, such as off smells, mold, or sliminess, even if the expiration date has not passed.
- Donate When Possible: If food is close to expiring but still safe, consider donating unopened items to food banks, following local laws and store policies.
For example, if you have a carton of eggs with a “sell by” date that passed two days ago, but you refrigerated them properly and they pass the float test (eggs that sink are fresh), you can still safely use them. This combination of understanding labels and common safety practices helps balance safety with avoiding waste.

Frequently asked questions
Can I trust expiration dates completely when deciding to eat food?
Expiration dates provide useful safety guidelines, but they aren’t absolute. Use your senses to check for spoilage, and follow storage instructions. If food smells bad or looks off, discard it even if the date hasn’t passed.
Are expiration dates laws the same across all states?
No, expiration dates laws vary by state, especially for perishable foods. Some states require strict adherence to these dates, others treat them as advisory. Check your state’s health department for local rules.
Is it legal to sell expired food?
Selling expired food is generally prohibited by state laws, especially for perishable items. However, the definition of “expired” depends on the label type and local regulations, so policies vary.
How should I interpret “best before” versus “use by” dates?
“Best before” dates indicate quality rather than safety, so food may be safe to eat after this date. “Use by” dates are about safety, and consuming food after these dates is riskier.
What should I do if I find expired food in my home?
Inspect it carefully using sight and smell. If the food shows spoilage signs or is past a “use by” date, throw it away. For “best before” dates, use judgment and storage history to decide.
Where can I learn about safe food storage to extend shelf life?
Government resources like FoodSafety.gov and USDA’s MyPlate offer detailed tips on storing different foods safely to help you maximize freshness and safety.
