Yes, midwestern here. Most of the meat in the midwest comes from travelers who stop at places that aren't Cracker Barrel. We leave the Cracker Barrels alone because we also find the people who eat there disgusting.
The chewed open boxes should have been a big clue. The barrel was the packaging. I'm also guessing they weren't crawling with maggots, as would be found in a traditional cracker barrel.
No, we know because somebody recorded the video. They're not exactly the same thing.
