As surprising as it may be, the human flesh walkers eat on the show is not really made from humans. It’s actually something far more disgusting – hams soaked in vinegar. Originally they were covered in barbecue sauce, but when that kept ruining their makeup, so the hams were plunged into a huge vat of vinegar to give it a nice oozy sheen. Understandably, after watching walkers chow down on their friends like a pack of wild hyenas during Christmas, many of the show’s actors have admitted to going off meat altogether.
One exception to the hammed guts main course, was the death of Dale. This was actually one of the more expensive deaths filmed (not counting CGI costs) because they used boneless chicken breasts for his innards. But regardless of what type of marinaded meat the show is serving up that day, if you’re hoping to be an extra on The Walking Dead and are a vegetarian, you might be out of luck.
