McDonald’s McRib contains over 70 ingredients.

Last year marked the “McRib’s” 30th anniversary. The idea for it was conceived during McDonald’s Executive Chef Rene Arend’s trip to Charleston, South Carolina. 

After trying a variety of pulled pork sandwiches from throughout the city, he thought the flavor combination “should really go over.” 

And it kind of had to, because McNuggets were so popular that McDonald’s couldn’t keep up with demand, and they needed a new product. The sandwich’s 70 different ingredients includes “pig tripe, heart, and scalded stomach” as well as azodicarbonamide, ammonium sulfate, ethoxylated mono, etc. 

If it’s any consolation however, contrary to the urban legend, the sandwich does not contain Kangaroo meat.
