13. Vinegar
Like honey, pure vinegar has an essentially indefinite shelf life. Its high acidity makes it self-preserving and inhospitable to bacterial growth. White vinegar, apple cider vinegar, and balsamic vinegar can all be used safely years or even decades past any printed date. Some slight changes in flavor or appearance may occur over long periods, but the product will remain safe and functional indefinitely.
14. Frozen Foods
Foods that have been kept continuously frozen are safe to eat indefinitely from a food safety standpoint, regardless of the date printed on the packaging. The USDA confirms this clearly. The main concern with frozen foods held for extended periods is freezer burn — dehydration that affects texture and flavor — and eventual rancidity in high-fat items. But these are quality issues, not safety issues. Frozen vegetables, fruits, and meats all remain safe as long as they have been continuously frozen.
15. Chocolate
Chocolate can safely be consumed for months to over a year past its printed date, depending on the type. Dark chocolate lasts the longest, followed by milk chocolate, then white chocolate. You may notice a white or grayish film developing on the surface of older chocolate — this is called "bloom" and occurs when cocoa butter or sugar migrates to the surface. It is completely harmless and does not affect safety, though it may slightly alter texture. If the chocolate smells and tastes normal, eat it without concern.
16. Crackers and Chips
Crackers, chips, pretzels, and similar dry snacks can safely be consumed for several months past their best-by dates. The main change is a loss of crunchiness — they become soft and stale rather than crisp. This is a quality issue, not a safety one. Spreading crackers on a baking sheet and warming them briefly in a low oven can restore much of their original crispness. They will not make you sick.
17. Coffee
Whole bean or ground coffee can safely be consumed months to years past its printed date — it simply loses flavor and aromatic intensity over time. Stale coffee is unpleasant but completely harmless. Properly stored coffee (in an airtight container away from heat, light, and moisture) holds its quality much longer. Coffee is never unsafe to drink past its date — it just may taste disappointingly flat.
