Most people get this wrong and toss out the can. The right way to read 'Best By' or 'Best Before' dates.


In the realm of packaged foods, the phrases Best By and Best Before are ubiquitous, yet they remain among the most misunderstood labels in the grocery store. Contrary to popular belief, these dates do not signal the moment food becomes unsafe to consume. Instead, they indicate the window during which a product is likely to be at its peak flavor, texture, and nutritional quality. Unfortunately, this widespread confusion prompts millions of consumers to discard perfectly edible food, significantly contributing to the global crisis of food waste. Learning to accurately interpret these labels, particularly regarding canned goods, is a simple step toward making smarter, more sustainable choices.

To navigate the grocery aisle with confidence, it is essential to understand the true purpose of these dates. Manufacturers establish Best By dates as a guideline for optimal quality, factoring in the specific food type, packaging materials, and ideal storage conditions. With the notable exception of infant formula, these dates are not federally regulated as safety deadlines. This is where the crucial distinction between Best By and Use By comes into play. While Best By speaks strictly to quality, Use By is typically found on highly perishable items like dairy or deli meats and carries a stronger safety implication that should be closely followed. Treating a Best By date as a hard expiration deadline is a common misconception that leads to unnecessary waste, especially for shelf-stable items that can remain perfectly safe for years beyond the printed date.
