You could try going to the McDonalds website at WWW.mcdonalds.com they have lots of information there and if they dont have what you are looking for you could try writing them and I'm sure they would be happy to help you.
I belive that this is really the wrong place to look because the McSpotlight People dont really know what they are talking about.
McSpotlight: Actually, we do. We just don't feel the need to lie to people because profits depend on it. If you examine the transcripts of the McLibel trial, you will see that many of the claims made in the original "What's Wrong with McDonald's?" are actually drawn from McDonald's internal sources...
