Off topic, but talking about truth in advertising: on your second link, there's a link at the bottom talking about a mummy made from McDonald's burgers that will never deteriorate. I'm tired of seeing this incredibly misleading claim that this is the reason the burgers are unhealthy.

Cooked and salted meat is, in essence, incredibly well preserved. This concept has been known since ancient times. Bacteria requires moisture to cause decomposition, and cooking/salting meat causes it to dry faster than it will rot. Once it's dried, it pretty much won't deteriorate any more. This is the concept behind pemmican and beef jerky.

The point is, there may be misleading advertisements, but this argument isn't any less disingenuous than the Big Mac that's too big to fit in a box.
