Most People Get This Wrong: The Right Way to Read ‘Best By’ or ‘Best Before’ Dates

Every time you stand in front of your pantry, eyeing that can of beans or jar of tomato sauce, you’ve likely paused at the “Best By” or “Best Before” date and wondered: “Is it still good?”

Most people throw away food prematurely, misinterpreting these dates as hard expiration warnings. This simple misunderstanding contributes to millions of tons of food waste every year and costs households hundreds of dollars. Understanding the difference between these dates, how they’re determined, and how to use your senses to evaluate food safety can save you money, reduce waste, and even improve nutrition.

Here’s the definitive guide to reading food labels correctly, using canned, packaged, and refrigerated items with confidence, and knowing when food is genuinely unsafe.

Step 1: Understand What the Labels Mean

‘Best By’ / ‘Best Before’

• Definition: Indicates the date when the product is at peak quality, flavor, or texture.

• Important: This is not a safety expiration date. Products can often be consumed after this date if stored correctly.

Example: A “Best By August 2026” can of soup may taste slightly different after the date but is still safe to eat for months or even years if unopened.

‘Use By’

• Definition: This is the manufacturer’s recommended date for safety and peak quality, especially for perishable items.

• Important: For foods like milk, meat, or fresh juices, do not consume past this date, as the risk of spoilage increases.

‘Sell By’

• Definition: Indicates to stores how long a product should be displayed for sale.

• Important: Not intended for consumers; food is usually still safe after this date.

Key takeaway: Only “Use By” is generally tied to safety, while “Best By” or “Best Before” is quality-related.

Step 2: Why Labels Can Be Misleading

Manufacturers set conservative dates for several reasons:

1. Legal Protection: To avoid lawsuits in case someone becomes ill.

2. Marketing Standards: Ensures consumers get the product at its peak flavor and appearance.

3. Supply Chain Variability: Dates account for shipping delays, storage variations, and retailer turnover.

Reality Check: Many canned goods, dry foods, and frozen items remain perfectly edible long after their “Best By” date if stored correctly.

Step 3: The Science Behind Cans and Packaged Goods

Canned foods and packaged goods undergo preservation processes that extend shelf life:

• Canning: Uses heat to destroy bacteria and seal in a vacuum, preventing contamination.

• Drying: Removes water, preventing microbial growth.

• Vacuum Sealing: Reduces oxygen, slowing spoilage.

• Freezing: Stops bacterial growth almost completely.

Shelf Life Insight:

• Canned vegetables: Typically safe for 2–5 years beyond “Best By.”

• Canned beans: Often last 2–3 years beyond the label.

• Tomato paste, sauces, soups: Can last 1–2 years unopened.

---

Step 4: How to Read a Can Properly

Not all canned goods are the same. Look beyond the date:

1. Inspect the Can

• Bulging, leaking, or rusted cans: Do not consume; this indicates bacterial growth or contamination.

• Dents along the seams: Avoid, as these may compromise the seal.

• Swollen tops or unusual sounds when opened: Signs of spoilage.

2. Check the Contents

• Appearance: Color changes may indicate oxidation but not necessarily spoilage.

• Texture: Slimy textures or separation can signal spoilage.

• Smell: A sour, off, or metallic smell is a clear warning sign.

Even if the “Best By” date has passed, a properly stored, intact can often contains safe and nutritious food.

Step 5: Practical Tips for Common Foods

Canned Goods

• Shelf-stable for years if unopened.

• High-acid foods (tomatoes, citrus) have a shorter shelf life—generally 1–2 years past the date.

• Low-acid foods (beans, corn) can last 2–5 years.

Dry Goods

• Pasta, rice, and beans: Safe indefinitely if kept dry and sealed.

• Cereals and crackers: Flavor may decline, but safe for months after date.

Dairy and Eggs

• Milk and yogurt: Check the smell and texture; often good for a few days past “Best By.”

• Eggs: Can last 3–5 weeks beyond carton date if stored in the refrigerator.

Frozen Foods

• Maintain quality past “Best By” for months if continuously frozen.

• Ice crystals indicate texture changes, not spoilage.

Step 6: Reduce Waste with Smart Practices

Understanding labels is the first step; proper storage is next.

Storage Guidelines

1. Pantry: Cool, dark, dry place; avoid temperature fluctuations.

2. Refrigerator: Store dairy, meat, and perishable products immediately.

3. Freezer: Keeps most foods safe almost indefinitely; use for long-term storage.

Rotation System

• Use a first-in, first-out method: place newly bought items behind older ones.

• Check dates weekly and plan meals using older items.

Batch Freezing

• Freeze portions of perishable foods before “Best By” to extend usability.

Step 7: Using Your Senses to Judge Safety

Labels are only part of the story. Learn to trust your senses:

1. Look – Changes in color or texture are warning signs.

2. Smell – A sour or rancid odor = discard.

3. Touch – Slimy or sticky texture = discard.

4. Taste (if safe visually and by smell) – Slightly stale or less flavorful is okay, but don’t force tasting if in doubt.

This approach empowers you to avoid wasting food unnecessarily.

Step 8: Special Cases and Exceptions

Certain items require more caution:

• Canned meat or fish: Can last 3–5 years if unopened; discard if can is damaged or smells off.

• Nut butters: Oils may separate, but flavor is usually intact months past “Best By.”

• Condiments: Ketchup, mustard, soy sauce often safe long after the label, though color may darken.

High-acid and low-pH foods spoil faster, while low-acid foods are more stable.

Step 9: Myths About ‘Best By’ Dates

1. Myth: “Best By” = expiration

   • Truth: It indicates peak quality, not safety.

2. Myth: Food immediately goes bad after the date

   • Truth: Many foods last months or years with proper storage.

3. Myth: Freezing changes “Best By”

   • Truth: Freezing preserves both quality and safety, effectively extending life.

Understanding these distinctions can save money and reduce waste.

Step 10: Maximizing Nutrition

Even past “Best By” dates, many nutrients remain:

• Canned vegetables: Minimal loss of vitamins C and A if sealed properly.

• Grains and beans: Protein and fiber remain intact for years.

• Frozen fruits: Nutrients remain stable if freezer is continuous.

Discard only when spoilage is clear, not merely because the date has passed.

Step 11: Tools to Help Track Food

• Pantry labels: Mark purchase date and intended use date.

• Apps: Track “Best By” dates and alert you to items nearing the date.

• Containers: Clear jars or labeled bins help you rotate items efficiently.

These tools reduce uncertainty and prevent unnecessary disposal.

---

Step 12: Eco-Friendly Practices

• Reduce food waste by understanding labels

• Donate unopened, safe products nearing “Best By” to food banks

• Compost truly spoiled items instead of sending them to landfill

Impact: A single household can save hundreds of dollars annually and reduce environmental footprint.

Step 13: Summary Table – Understanding Labels

Label Type	Meaning	Consumer Action
Best By / Before	Peak quality, flavor, texture	Safe to eat after date; quality may decline
Use By	Recommended for safety and quality	Do not consume after this date
Sell By	Store guidance for inventory rotation	Food usually safe beyond this date

Conclusion

Most people misinterpret “Best By” or “Best Before” dates, tossing out perfectly edible food. Understanding the difference between quality vs. safety, inspecting cans and packaging, trusting your senses, and using proper storage techniques can save you money, time, and frustration.

The next time you reach for that can or jar, remember: the label is a guideline, not a deadline. With careful observation and common sense, you can enjoy safe, nutritious, and flavorful food well past the “Best By” date.

By mastering this simple knowledge, you not only save money but also contribute to reducing food waste and making your household more sustainable. In a world where millions of tons of food are wasted each year, a little education goes a long way.
