In 2010 I posted a photo of "pink goop," which Fooducate says is mechanically separated chicken. In the video above, McDonalds Canada visited the factory where Chicken McNuggets are made and showed the process. The ground chicken used in Chicken McNuggets is not nearly as pink or as goopy as the goop in the infamous photo.
