WATCH: How Is Your McRib Made?

In another attempt to restore its image, McDonald's has released the newest footage in its line of myth-busting videos starring ex-MythBuster Grant Imahara. This time, they're taking on the McRib: the infamous BBQ sauce-soaked pork patty sandwich that haters love to hate. In this video, McDonald's is out to prove that the only things that go into the McRib are pork, BBQ sauce, and a handful of preservatives and pickles. The video was released in response to a photo that went viral last year of what looked like a frozen pink-ish brick, which was supposedly an image of the beloved McRib straight out of the box.

In fact, the guy who originally posted the image stars in this video. McDonald's transported him to McDonald's pork headquarters in Oklahoma for him to get a mild slap on the wrist in the form of McRib education. The video shows slices of pork shoulder being ground up while water, salt, dextrose, and preservatives are added to the mixture. The pork is then formed into its well-known rib-like shape via McMachines.

The preservatives added to the pork mixture to "lock in flavor" include BHA (a preservative that is safe in low doses but has been shown to act as a carcinogen in high doses), and propyl gallate (an antioxidant and preservative that has also been suspected to be possible carcinogen and is banned in other countries). Also, the bread used for the McRib sandwich contains a hearty dosage of azodicarbonamide, or that "yoga mat" material Subway recently removed from its bread.

McRib season nationwide starts this week.
