On the internet, misinformation can spread like wildfire. Such has been the case with McDonald's meat, particularly the McRib, which is certainly pork but not a cut of rib meat.

The McRib is made of pork shoulder. A lot of people's favorite barbecue pulled pork sandwiches are made from the shoulder, so this part of the pig is safe to consume.

It's fair to be miffed at a company for naming its sandwich a "McRib" despite not being made from ribs, but calling it a "McShoulder" wouldn't have the same effect.
