I would have eaten it. For one thing, it was frozen twelve hours earlier. It probably didn’t reach room temperature for several hours.
You didn’t say if it was wrapped in packaging or not, either. If it was, then I would have had no worries.
Pork is salted and smoked into bacon so that it will last longer. It’s full of preservatives (salt, smoke, nitrates, whatever one puts into bacon.) People used to live on bacon when they had no refrigeration.
If there is no foul odor, it’s probably safe. If it’s cooked, it’s probably safe. Cooking would kill anything that could possibly grow in meat.
I would not only have eaten it, I would have given it to my children, no problem.
