How important are expiration dates for food products?
Every year, a significant amount of food in the United States goes to waste, with confusion surrounding labeling dates contributing to this issue. It is important to understand what these dates really mean.
Contrary to popular belief, the “best if used by” or “best before” date is not an expiration date. Instead, it indicates when a product is likely to have the best flavor or quality. Similarly, the “sell by” date is primarily for retailers, indicating how long a product should remain on the shelves.
The “freeze by” date is the last recommended day for freezing a product to maintain its peak quality, while the “use by” date signifies the last day a product can be used while still at its best quality.
According to experts, in most cases, these dates are not crucial for consumer safety. Many products can still be consumed past their “use by” dates, with some exceptions like infant formula, which is critical for infants’ nutritional needs.
Prepared foods and deli meats should be consumed by the date listed on their packaging to avoid harmful bacteria developing. Common concerns arise from microorganisms like E. coli, salmonella, and listeria.
Interestingly, many food products last longer than most people expect. For instance, canned goods and frozen raw meat can remain safe and good to eat long after their dates. However, proper storage is vital for longevity.
“Food that has been opened generally lasts around five to seven days in the refrigerator,” which varies depending on the product and storage conditions.
In summary, understanding food labeling and expiration dates can significantly reduce food waste. Knowing that most products maintain their quality well beyond the printed dates helps consumers make more informed decisions about food safety and waste reduction.
