Is the roast safe to eat?

yes

Hello mjw263.
Toss it out.
Room temperature over two hours is a health risk.

I'd eat it.

The residual heat in the crock pot would have kept it hot/warm for another few hours.

Nine hours sitting in there.

Be safe. Toss it.

You probably could eat it, but why take the risk? Bacteria begin to work on protein at around 2 hours when at room temperature, so after 9 hours, you can just imagine what's been going on. You might not get sick if you have a cast iron stomach, but ... ick.

Pshaw! It's safe to eat assuming you fully cooked it in a clean crock pot in the first place.

in the food service world anything longer than 4 hours in the danger zone requires discard, that being between 40-140 degrees F. In your case the food would have stayed above 140 for much of that time, and hopefully you had the good sense to put the food in a different container when you put it in the fridge because stone would chill slowly.

If you did not transfer the food when you put it in the frig then I would not eat it. If you did it should be fine, but only if you eat it very soon, like in the next day. The bacteria have begun the infestation, but their numbers should be reasonable for now.

The most reasonable answer here. Give him the right answer prize.
