It’s probably happened to you: you check your refrigerator and find a yogurt that’s past the expiration date indicated on the package. Should you throw it away or can you still eat it? The answer is more complicated than it seems. Food labels usually indicate when the quality, flavor, or freshness begins to decline, not necessarily when the food becomes dangerous to your health.
The confusion about expiration dates is so widespread that it’s estimated that billions of kilos of food are thrown away every year for this reason. In this article, we’ll debunk the myths, explain what the labels really mean, and give you the keys to knowing when it’s safe to eat expired food and when it’s not.
The chaos behind expiration dates
The food industry’s labeling system is a complete mess. There is no standardized regulation globally. Each company establishes its own methodologies for determining the shelf life of its products.
For example, some companies use mathematical models or subject food to extreme heat and humidity tests to predict spoilage. Other, smaller companies simply rely on competitors’ best-by dates.
This creates an inconsistent system where two nearly identical products can have completely different expiration dates, causing chaos for consumers and increasing food waste
Quality vs. Safety: The key is in the language
For most foods, the key is in the language on the labels. Not all of them mean the same thing:
- “Best before”: This is a quality indicator . The product will still be safe after the date, but its flavor, texture, or color may not be optimal.
- “Sell By”: This date is for store staff only. It indicates when the retailer should remove the product from the shelves to ensure inventory freshness.
- “Expiration date” or “Expires on”: This is the most important and the one that is linked to food safety , especially in perishable products
Fortunately, many foods last much longer than the expiration date. For example, unopened condiments and preserves can last for years, and refrigerated eggs are safe for 3 to 5 weeks.
When is it really dangerous to eat something that has expired?
Although most labels are quality guidelines, there are some foods you should be more careful with. Pay special attention to the expiration dates on:
Raw meats and seafood: These are the most susceptible to bacteria. Experts recommend consuming chicken within 1 to 2 days and red meat within 4 to 5 days of purchase.
Unpasteurized milk and cheeses: These products have a higher risk of harboring dangerous pathogens.
Baby food and infant formula: These are the only products with government-regulated expiration dates. Their expiration dates are strictly enforced for the health of the little ones.
Beyond labels, the best guide is your common sense. If a food smells off, has mold, or has changed its texture in an unusual way, don’t eat it, regardless of the expiration date on the package.
The bottom line is that it’s not that simple.
The answer to whether you can eat expired food isn’t a simple “yes” or “no.” The current labeling system is designed to confuse, but understanding the language and using your judgment is the best way to reduce food waste and protect your health.
Don’t let the expiration date on a package make you throw away perfectly good food. Check the language, use your senses, and when in doubt, always consult reliable resources. Your wallet and the environment will thank you.
