Is It Safe To Eat Expired Food? Absolutely, understanding expiration dates and food safety is crucial, and FOODS.EDU.VN is here to guide you through it. By knowing the difference between “use by,” “sell by,” and “best if used by” dates, you can reduce food waste and save money, while ensuring your safety. Explore FOODS.EDU.VN for expert advice on food spoilage, safe food handling, and extending the shelf life of your groceries.
1. Decoding Food Date Labels: Is It Safe to Consume Foods Past Their Expiration?
Yes, most foods are safe to consume past their expiration dates, but it depends on understanding what those dates actually mean. Date labels on food products, such as “use by,” “sell by,” and “best if used by,” are often misunderstood. These dates primarily indicate the manufacturer’s estimate of peak quality and freshness, rather than safety. The USDA does not require date labeling on food products, with the exception of infant formula, leaving manufacturers to decide whether to include dates and which phrases to use.
1.1. Understanding “Use By,” “Sell By,” and “Best If Used By”
Confusion around these labels leads to significant food waste, as consumers often discard food that is still safe to eat.
- “Use By”: This date suggests when the product will be at its peak quality and flavor. It is not a safety date, except for infant formula.
- “Sell By”: This date informs the store how long to display the product for sale. You can still safely consume the food after this date if stored properly.
- “Best If Used By”: This date indicates when the product will have the best flavor or quality. It is not a purchase or safety date.
1.2. The Role of Food Manufacturers and the USDA
Food manufacturers determine if they want to put dates on labels and what phrases to use, according to Elizabeth Traxler, MS, RDN, LD, a registered dietitian. This lack of standardization can confuse consumers. The USDA only mandates date labeling for infant formula to ensure nutritional content and safety for infants.
1.3. How to Minimize Food Waste Based on Expiration Dates
To minimize food waste, rely on your senses rather than solely on expiration dates. The taste, smell, and appearance of the food are better indicators of spoilage.
- Smell Test: If the food has an off or foul odor, it’s likely spoiled.
