Should You Follow Expiration Dates on Food?
Short answer
You should generally follow expiration dates on food as guidelines for quality and safety, but they are not always strict indicators of spoilage. Understanding what these dates mean, how they differ, and how to use your senses to assess food can help you decide when food is still safe to eat or when it should be discarded.
What Are Expiration Dates on Food?
Expiration dates are printed labels on food packaging that indicate the manufacturer's estimate of how long a product will maintain its best quality or remain safe to eat. These dates can be called "Use By," "Best By," "Sell By," or "Expiration Date," and each has a slightly different meaning. For example, a "Best By" date suggests when the product will be at its peak flavor or texture, while a "Use By" date is often the last recommended day for use to ensure safety, especially for perishable items. These dates are set based on tests for freshness, taste, and safety, but they are not federally required for all foods in the U.S. Recognizing these labels helps consumers understand when food may no longer be optimal but doesn’t always mean it’s unsafe.
How Do Expiration Dates Work in Practice?
Expiration dates guide how long food is expected to maintain quality under proper storage conditions. For example, imagine buying a jar of pasta sauce with a "Best By" date three months from the purchase date. If stored unopened in a cool, dry place, the sauce is likely to retain flavor and quality until that date. Once opened, the sauce might only last a week in the fridge. If you find the jar a few days past the date but it smells and looks fine, it might still be safe to eat. However, if you notice mold or an off smell, it should be discarded. These dates assume ideal conditions; improper storage can shorten a food’s safe lifespan.
Why Should You Care About Expiration Dates?
Expiration dates exist to help protect consumers from eating spoiled or unsafe food and to ensure food tastes as intended. For individuals, following these dates can reduce the risk of foodborne illness, which can cause stomach upset or more severe health issues. They also help avoid wasting food by providing a timeline for use. Understanding expiration dates helps you manage food in your kitchen better—planning meals, storing food safely, and knowing when to trust your senses versus the printed date. For families, especially those with young children, older adults, or people with weakened immune systems, paying attention to expiration dates can be especially important.
What Are the Different Terms on Expiration Labels?
Many people confuse terms like "Sell By," "Best Before," and "Use By." Here is a quick guide:
| Term | Meaning | Purpose |
|---|---|---|
| Sell By | Last date store should sell the product | Helps stores manage inventory |
| Best By | Date for best flavor or quality | Suggests peak freshness |
| Use By | Last date recommended for safety | Indicates safety limit |
| Expiration | Date after which product shouldn’t be eaten | Safety-focused |
Knowing these differences helps you decide whether to use your senses or strictly follow the date. For instance, "Sell By" is mostly for stores and doesn't mean the food is bad immediately after that date.
Can Food Be Safe After Its Expiration Date?
Many foods remain safe to eat after the printed date if stored properly and checked carefully. For example, dry pasta or canned goods might be fine weeks or months beyond their dates. However, perishable foods like dairy, meat, and fresh juices should be treated more cautiously. It's best to observe:
- Appearance: Look for mold, discoloration, or sliminess.
- Smell: A sour or off smell indicates spoilage.
- Texture: Changes like curdling or mushiness may mean the food is bad.
When uncertain, it’s safer to discard the item. This approach balances minimizing food waste with protecting health.
What Should You Do Next When You See an Expiration Date?
When you buy food, check the expiration dates and plan to use items with closer dates first. Store food according to instructions on the packaging—like refrigerating dairy or freezing meat if not used soon. Before eating, inspect the food visually and with smell and texture checks. If the food looks and smells normal, it’s usually safe to consume even a bit past the date. When cooking, follow safe food preparation guidelines to reduce risks. For leftover foods, mark dates when they were stored to track freshness. If ever unsure about safety or if food shows signs of spoilage, discard it to avoid risk.
How Are Expiration Dates Regulated and Why Does It Matter?
In the U.S., food expiration date regulations vary by product and state, with no uniform federal requirements for most foods. Some products like infant formula have strict rules, while others use dates voluntarily. This lack of standardization can be confusing. Understanding this can help consumers not rely solely on dates but use informed judgment. For example, some states may require "Sell By" dates on milk, while others do not. If you want to learn more about how dates are regulated and what each term means legally, resources like the FDA or USDA provide detailed information. This knowledge helps in reading labels accurately and managing food safety at home.
How to Avoid Common Mistakes Regarding Expiration Dates?
Many people throw away food too early or consume it too late, leading to waste or health risks. Here are practical tips:
- Organize your fridge and pantry: Place older items at the front.
- Understand label terms: Don’t confuse "Sell By" with "Use By."
- Use your senses: Smell, sight, and texture checks are crucial.
- Follow storage instructions: Proper refrigeration or freezing extends life.
- When in doubt, throw it out: Safety first.
Following these steps helps balance safety and reduces unnecessary waste.
Frequently asked questions
Can I eat foods after the "Best By" date?
Yes, "Best By" indicates peak quality, not safety. Many foods remain safe after this date if they look, smell, and taste normal, but always check for spoilage signs.
What’s the difference between "Use By" and "Sell By" dates?
"Use By" is the last date recommended for safety, especially for perishable foods. "Sell By" is for stores to manage stock and doesn’t mean the food is bad immediately after.
Are expiration dates required on all foods?
No, not all foods require expiration dates in the U.S. Regulations vary by product and state, with some foods having mandatory dates and others voluntary.
How should I store food to extend its freshness past the expiration date?
Follow the package instructions—refrigerate perishable items promptly, keep dry goods in cool, dry places, and freeze foods if not using them soon to slow spoilage.
What should I do if food smells fine but is past the expiration date?
If the food shows no signs of spoilage like mold or texture changes and smells normal, it is usually safe to eat. Use caution with perishable foods and trust your senses.
How can I reduce food waste related to expiration dates?
Plan meals around items nearing expiration, store food properly, understand label meanings, and check foods visually and by smell before discarding.
