The Food Lab: Here's Why McDonald's Burgers Don't Rot

Long story short: McDonald's burgers don't rot because they dry out, that's it. If you think a McDonald's burger that doesn't rot is unnatural and gross, you should also count saltine crackers, beef jerky, hardtack, croutons, dried beans, or pretty much any nutrient-rich, shelf-stable food in your pantry as unnatural and gross. The reason a McDonald's burger doesn't rot has nothing to do with chemicals, lack of nutrition, or anything else you should be scared of. It all comes down to water activity.

See, a McDonald's hamburger is small and thin, giving it a very high ratio of surface area to volume. It is cooked well-done on a very hot griddle. These factors contribute to rapid moisture loss, resulting in a burger that dries out long before it can start to rot. Moreover, the burgers are cooked in a food-safe environment to a very high temperature that kills any bacteria, and are thus relatively free of any agents of decay to begin with.

Map Showing Where Today’s Countries Would Be Located on Pangea

The supercontinent of Pangea formed some 270 million years ago, during the Early Permian Period, and then began to break up 70 million years later, eventually yielding the continents we inhabit today. Pangea was, of course, a peopleless place. But if you were to drop today’s nations on that great land mass, here’s what it might look like.

Diving between two tectonic plates

The Silfra crack in Iceland runs beneath Þingvallavatn Lake. The fissure lies between the plates of Europe and America making it possible for divers to touch both continents at the same time.
