Can I get food poisoning from this?

So, here's the story. I had a one-pound package of frozen bacon in my car last night. I forgot about it and it stayed in there for roughly 12 hours. This afternoon at about 3 o'clock, I went out to my car to get the bacon. It was about 82 degrees today and the bacon was well thawed, needless to say. I put the bacon in the refrigerator and at around 7 o'clock, I thoroughly cooked the lot of it and ate it all in one sitting, not thinking that it would really be a problem. So, my question is, could this be harmful? The package was vacuum sealed and no air was in it when I put it in the refrigerator.
