I would think the amount of sugar found in commercially cured bacon is probably negligible. I've never seen bacon that had any carbs listed on the packaging and it's usually one of the last ingredients listed. That being said, I usually buy the Plumrose bacon with 25% less sodium and it's listed as sugar free. Admittedly, I don't eat much bacon, so it's not an issue to me. I probably haven't eaten any in a month or two.
