How to tell if bacon is bad

Slick, slimy surface on slices or links.

Colour

Grey, green or iridescent patches that spread.

Mould

Fuzzy spots on sliced or cooked products — discard.

Bacon past the expiration date

Unopened

FoodKeeper gives unopened bacon 1 week in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.

Opened

Once opened, the printed date no longer applies. Count 1 week in the fridge from the day you open it.

How to keep bacon fresh longer

  • Keep refrigerated at 40°F (4°C) or below, even though it is cured.
  • Once opened, rewrap tightly or move to an airtight container.
  • Use within the opened window regardless of the package date.
