Yes. Kielbasa and smoked sausage last 1 week in the fridge and 1–2 months in the freezer. After that, or sooner if stored badly, they spoil: watch for the signs below.
How to tell if kielbasa and smoked sausage are bad

Sour or rancid smell instead of smoky or salty.

Kielbasa and smoked sausage past the expiration date
Best-by and sell-by
FoodKeeper gives unopened kielbasa and smoked sausage 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.
Past the date
For perishable kielbasa and smoked sausage, the storage clock matters more than the label: if it has been in the fridge longer than 1 week, discard it even before the printed date.
How to keep kielbasa and smoked sausage 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.
