Food expiration dates, those “use by” and “best by” dates that you see stamped on both perishable and nonperishable products, are actually suggestions for peak quality. It is a common misconception that these are an indication of safe food, which may be better assessed by using your senses to check for off colors or smells. The exception is the “use by” date on infant formulas and eggs, which are regulated by the USDA and indicate when you should no longer consume the product.
Energy, water, and fossil fuels that are required to grow, harvest, transport, package, market, and sell food also get wasted. These resources are not renewable! Food decomposing in landfills is a significant source of methane emissions, a potent greenhouse gas that traps heat in the atmosphere.
Food security is no doubt still a goal over 60 years after independence. In contrast, China that comes a distant second world over after food wastage, has tried to cap wastage by laying thrust on infrastructure development to quickly transport the produce and minimize transit losses.
