Generally speaking, uncooked bacon should not sit out for more than two hours at room temperature. The reason is that bacteria such as Staphylococcus and Salmonella can multiply rapidly at room temperature and cause severe foodborne illness when consumed. So if your raw bacon has been sitting out longer than two hours, as painful as it may be, it’s best to toss it in the trash.

Unfortunately, this is also true for raw turkey bacon and frozen raw bacon that has been sitting out as well.
