Food Date Labels: Safety, Quality, Sell-By, Use-By, and Best-By

A printed date can describe inventory or peak quality. It cannot tell you whether the milk sat warm in a car or the chicken leaked in the refrigerator.

U.S. household guidance: These pages use USDA, FDA, and FoodSafety.gov recommendations. Local rules may differ. Pregnant people, adults 65 and older, children under 5, and people with weakened immune systems face higher foodborne-illness risk and may need stricter choices.

Most U.S. food dates describe quality

USDA says that, except for infant formula, product dates generally are not indicators of safety and are not required by federal law. Manufacturers and retailers use dates to communicate expected quality or manage inventory.

What common phrases mean

  • Best if Used By/Before: expected peak flavour or quality; not a purchase or safety date.
  • Sell-By: store inventory guidance; not a consumer safety deadline.
  • Use-By: manufacturer’s last recommended date for peak quality; generally not a federal safety date except for infant formula.
  • Freeze-By: a quality suggestion for when to freeze, not proof the item is unsafe the next day.

The infant-formula exception is real

Do not buy or use infant formula after its use-by date. The date supports nutrient content and product quality needed for feeding. Follow preparation, storage, and discard instructions exactly; this is not an area for smell-based improvisation.

Storage history outranks the date

A food can become unsafe before a printed date if left warm, cross-contaminated, or stored in a refrigerator above 40°F (4°C). Conversely, a properly handled product may remain wholesome after a quality date. Check the applicable cold-storage chart and the product’s time since opening.

Spoilage and pathogens are different

Spoilage bacteria can create off odours, flavours, and textures. Pathogenic organisms may not change smell or appearance. A sensory check can reject obviously spoiled food, but it cannot clear perishable food with unsafe time-and-temperature history.

Can codes are for traceability

Letters and numbers stamped on cans often identify production date, time, or plant for inventory and recalls. They are not a hidden consumer expiration code. Contact the manufacturer for interpretation when necessary.

Reduce waste with a system

  • Mark the open date on refrigerated packages.
  • Use a visible eat-first area.
  • Freeze food before its safe refrigerator window ends.
  • Consult FoodKeeper or the official cold-storage chart for the category.
  • Check recalls separately; a future date does not override a recall.

Damaged packaging changes the decision

Discard leaking, bulging, or severely damaged cans and packages. Do not taste a product to test for botulism or another hazard. Follow official advice for home-canned food, flood exposure, and recalls.

Decision order: Recall and package integrity, handling history, category-specific storage time, spoilage, then the quality date—not the date alone.
