how long are crab legs good after cooked
by Pam Morgan. (Sacramento, CA) Once you buy a cooked king crab legs from the store...how long is it good in the fridge before eating? When you buy cooked king crab legs from the store and place them in the fridge for future consumption it's a good rule of thumb to treat them like any other meat you would purchase. We, personally, wouldn't keep them stored in the fridge for longer than 4 or 5 days at the maximum time if we want to enjoy them safely.
