How long does it take frozen meatballs to go bad after being left out?

If you were to leave an almost entirely full 6 pound bag of meatballs on the counter right after pulling them out of the freezer, and not do anything with them for 8 hours, would they still be good to eat after cooking them?
Update: We're cooking them anyway and we're just going to hope no one gets sick. However since it was my fault and I feel bad, I just wanted to make sure no one would get sick.
