A photograph of that "goo" went viral with the caption, "Can you guess what McDonalds food item this is." It's said to be the entire chicken, eyes, guts, bones ground up into something called mechanically separated poultry.
Not us, says McDonalds. They say it is a photo hoax. But, the rumor of pink goo won't go away. Now, McDonalds of Canada has taken the goo by the horns, directly addressing the question in a Super Bowl commercial seen only in Canada.
McDonalds wants you to see what's in their McNuggets, so they've released a video tour. Starting with whole chickens, the breast meat is set aside to make McNuggets. That's pretty much it, ground up breast meat.
Two independent food science experts told CNN that McDonalds seems to be giving the straight scoop, though of course, there's nothing healthy about all the fat and salt in McNuggets.
One thing they're not making McNuggets into is the shape of a snake.
McDonald's posted this description on their YouTube video, "Armand R. from Edmonton, Alberta asked: "What are legitimately in mcnuggets is there pink goop?" Here's our answer: There's no "pink goop" in our Chicken McNuggets, Armand. We use chicken breast and a natural proportion of chicken skin used for flavor and as a binder. But your question is so popular, you've inspired us to show you how they're made. Check out this video for a behind-the-scenes look at our supplier's facility in London, Ontario, Canada. And see for yourself exactly what's in our Chicken McNuggets."
This is the video tour McDonald's Canada posted to their YouTube page:
