Chicken Nuggets are made with pink goo- fact or fiction?

Probably most of you by now have seen the picture of pick goo coming out of a silver machine claiming to be what chicken nuggets are made of.

(pause)...ahem...how to avoid writing this post without feeling nauseous?...not sure if it can be done.

Anyway, actual Chicken McNuggets are actually made with white meat just so you know.
I came across this lovely post concerning what is true and what is not about the "pink goo claim". I love how they ended with a video from Jamie Oliver's Food Revolution show - I highly recommend watching it (and other clips availabel from that show on YouTube.
