Ever opened the fridge to find a yogurt just past its date and wondered: is it still safe to eat? You’re not alone. Many households toss out food that might actually be fine, simply because of confusing expiry labels.
Understanding what those dates really mean can save you money, reduce food waste, and help you make safer, smarter choices at mealtime.
Understanding Food Expiry Dates
Not all dates on food packaging mean the same thing. The most common are ‘best before’ and ‘use by’ dates, but there are others too. These labels are designed to guide you, but knowing their differences is key.
- Best Before: Indicates when the product is at its best quality. Food is often still safe to eat after this date, though taste or texture may change.
- Use By: Linked to safety. You should not eat food past this date, especially for perishable items like meat or dairy.
- Sell By: For retailers, not consumers. It tells stores how long to display a product. Food may still be safe after this date if stored properly.
Why Do We Have Expiry Dates?
Expiry dates are meant to help you enjoy food at its best and avoid spoiled or unsafe products. They are based on how quickly food quality or safety can change. Factors include:
- How the food is processed (fresh, canned, frozen, dried)
- Packaging methods (vacuum-sealed, airtight, open)
- Storage recommendations (refrigeration, pantry, freezer)
But remember, these dates are estimates—not exact science. Food can spoil before or after the printed date depending on how it’s handled.
What Happens When Food Passes Its Date?
Food doesn’t instantly become unsafe the morning after its date. For many items, especially those labeled with a ‘best before’ date, the food may still be fine.
- Dry goods (pasta, rice, cereal): Often last months beyond their date if kept sealed and dry.
- Canned goods: Usually safe for a long time if the can isn’t damaged or bulging.
- Snacks and biscuits: May go stale rather than unsafe.
However, foods with a ‘use by’ date—such as ready-to-eat salads, fresh meat, and milk—should be treated with more caution. Eating these past the date increases your risk of foodborne illness.
How to Tell If Food Is Still Safe
Instead of relying only on the printed date, use your senses and good judgment. Here’s what to look for:
- Smell: Off or sour odors are a warning sign.
- Appearance: Mold, discoloration, or unusual texture mean you should toss it.
- Texture: Sliminess or fuzziness are signals to avoid eating the item.
- Sound: For canned goods, hissing or spurting when opened can mean spoilage.
When in doubt, it’s safer to throw it out—especially with high-risk foods like meat, fish, eggs, and dairy.
Reducing Food Waste Without Risk
Misunderstanding expiry dates leads to a lot of unnecessary food waste. You can help cut this down without compromising food safety:
- Plan meals so you use perishable foods first.
- Store foods as recommended—refrigerate or freeze promptly.
- Rotate pantry and fridge items so older products are used first.
- Get creative with leftovers or foods nearing their date—think soups, stir-fries, or smoothies.
Being mindful of expiry dates and your senses will help you waste less and save more.
Common Foods: Shelf Life and Safety Tips
- Milk: Smell and taste it—if it’s sour, don’t drink it. Store in the coldest part of the fridge.
- Eggs: A float test in water can help—fresh eggs sink, older ones float.
- Bread: Mold is the main concern. If you see any, throw out the whole loaf.
- Cheese: Hard cheeses may be safe if you trim off the mold; soft cheeses should be discarded if moldy.
- Yogurt: May be edible a few days after the date if it smells and looks normal.
- Fresh produce: Check for soft spots, mold, or an off smell.
Food Safety Basics
While expiry dates are helpful, basic food safety habits are just as important. Always:
- Wash hands, surfaces, and produce before handling food.
- Keep raw and cooked foods separate.
- Cook foods to safe temperatures.
- Refrigerate leftovers within two hours.
- Defrost foods in the fridge, not on the counter.
These habits reduce your risk of food poisoning, regardless of the date on the label.
Frequently Asked Questions
Can you eat food after the ‘best before’ date?
Usually, yes—if it looks, smells, and tastes normal. The quality may drop, but it’s often still safe for many types of food.
What foods should never be eaten after their date?
Foods like fresh meat, fish, deli salads, and soft cheeses can pose a higher risk. Do not eat these after their ‘use by’ date.
How can I make food last longer?
Store foods correctly, keep your fridge cold (below 5°C/41°F), and freeze items you can’t use in time.
What’s the risk of eating expired food?
The risk depends on the food and how it’s been stored. Eating spoiled food can lead to food poisoning, so always check for signs of spoilage.
The Bottom Line
Food expiry dates can be confusing, but a little knowledge goes a long way. By understanding the labels, trusting your senses, and practicing good food safety, you can cut down on waste, save money, and keep your meals safe. When in doubt, play it safe—especially with perishable foods—and don’t hesitate to speak to a healthcare professional if you have concerns about foodborne illness.
