After years of working in grocery stores, one employee has issued a compelling warning: not all expiration dates are created equal. While many consumers casually glance at “best before” or “sell by” labels, there’s one specific type of date that should never be taken lightly—the “use by” date. Unlike others, this date is often set for safety reasons, not just quality. Ignoring it can lead to serious health risks, especially with perishable items like meats, dairy, and deli-prepared foods.
Many people assume food is still good as long as it “looks fine” or “smells okay,” but that’s a risky assumption. Behind the scenes in grocery stores, staff are trained to remove products by the “use by” date because bacterial growth isn’t always visible or detectable by smell. Spoiled products can contain dangerous pathogens like Listeria or Salmonella, even if they seem fresh. This makes the “use by” label the most critical one, especially for vulnerable populations like children, the elderly, or those with weakened immune systems.
Shoppers are also urged to check for this date not only on fresh foods but also on ready-to-eat meals and refrigerated items, which may appear safe but spoil quickly after their designated period. Always store these products properly and avoid consuming anything past its “use by” date—no matter how appealing it still looks. Grocery employees often witness customers overlook this warning, leading to potential health hazards.
