You can leave it if you want, just don't eat the berries or any other part of it. Pull it out if there are small children around who might eat them.
If you REALLY wanted to, you could double- or triple-boil the young shoots and leaves in order to leach out the toxins, and then eat them. But it'd be a lot of trouble.
