Usually, no. Bacon is already cured and smoked when you buy it. However, most commercially available bacon isn't actually smoked. Instead, it's injected with a smoky flavor. So it's not safe to eat raw bacon, due to the potential risk of foodborne illness (not that you'd want to anyway, I bet). Also, because it's cured, bacon may appear pinkish evenly though it's fully cooked and totally safe to eat, FYI.
