There is always a risk with adding more live rock to an established tank, no matter where it came from. The risk of dieoff and unwanted hitchhikers is significantly lessened with cured live rock over uncured, but there's no guarantee.
Just because it came from your lfs doesn't mean it's safe... or even that it's cured. Just be certain that it is cured live rock before you add it to an established tank.
Of course, there is always the option of curing the rock yourself in a big rubbermaid container...
