Source. Who else here has observed several (or perhaps many, yech) food items which have "resisted decomposition" in the same way as Davies' Happy Meal Project? I find this particularly true in dry climates such as exists here in Colorado. Grapes that have rolled under the fridge. A pizza slice my son left in the microwave... Literally dozens of items over the years found their way into various locations around the house. The same thing happened to each and every one of them: They dried, and did not decay, even items containing absolutely no preservatives whatsoever. I discovered a far different story for those items in, near, or containing any moisture. They decayed (rotted, actually), in just a few days. The flaw I find in Davies' "test" is that there are no comparisons, no controls. Then again, she's an artist and a photographer, not a scientist. She doesn't know how to conduct any such "research" and certainly not a properly established and controlled scientific experiement. This is nothing more than sensationalistic nonsense, perpetuated by media folks who know know anything more about biology or scientific controls than Davies.
