Cooked lobster will last up to 4 days in the fridge before it goes bad.
After 4 days the cooked lobster will be going bad and should not be eaten and should be thrown out instead.
If you want to keep cooked lobster longer than 4 days you can and should freeze the cooked lobster to keep it longer.
When frozen the frozen cooked lobster should last 6 months to a year before it starts to go bad.
After 6 months the lobster will still be good to eat but it won't be as fresh to eat.
Lobster is expensive and delicious so it's best to eat the cooked lobster within a few days of cooking it.
When you freeze the cooked lobster you should freeze it inside covered airtight containers or heavy duty freezer bags, or wrap tightly with heavy duty aluminum foil or freezer wrap.
The freezer helps to extend the shelf life of the cooked lobster.
