Prosciutto past the expiration date
Best-by and sell-by
FoodKeeper gives unopened prosciutto 2–3 months 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.
Past the date
For perishable prosciutto, the storage clock matters more than the label: if it has been in the fridge longer than 2–3 months, discard it even before the printed date.
How to keep prosciutto 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.
