Raw sausage can be kept in the fridge for up to 3 to 4 days before it goes bad.
Cooked sausage can last for up to 7 days in the fridge.
If you want to keep the raw sausage longer than 4 days you can and should freeze the sausage instead.
When frozen the raw sausage can last for 6 months to a year.
The raw sausage when frozen is at it's best quality if eaten within 6 months although it's still safe to eat the frozen sausage even past a year.

Any longer than 2 days the raw sausage is best kept frozen to prevent it from going bad and prevent the raw sausage from growing bacteria.
