It is from those wee tiny nickel sized pygmy pigs that Hormel harvests the bacon from for this Spam product. I am sure there is a very hi-tech process for this, miniature farms no bigger than a conference room, tiny little smokehouses to hang the pork belly in and I am sure a fine laser guided slicing mechanism to slice the end product into the microscopic strips of bacon seen here. I am assuming there is bacon in the meat product, there are some dark flecks, but those could just be some other part of the pig that got ground up.
