Help please, I have 25 plus lbs of butt on, was running for 7 hours at avg of 250, IT was up to 172. Had to leave home, was gone longer then planned. Egg went down below 200, IT went down below 160. Got dome back to 300, IT is just starting to come back. Will have to foil to finish, but is the meat still safe? At 10 hours since cook started.
