KFC is a powerful brand in China, and that's why they're suing over the mutant-freak-bird thing. At Above the Law's Redline, Elie Mystal is on the case (emphasis ours):
The China branch is suing four companies it accuses of spreading false rumors about its food. The rumors? KFC uses genetically modified eight-legged, six-winged chickens.
[Re: Parent Company YUM Foods] … If it doesn’t actually kill you, stop asking what’s in it. We’ve been down this road with Taco Bell before: tacos are not supposed to be that cheap and tasty at the same time. If you are eating it, and don’t die, you’ve lost the right to ask questions.
To that, we can only add one thing.
