The Burger Lab: Revisiting the Myth of the 12-Year-Old McDonald’s Burger That Just Won’t Rot (Testing Results!)

You know the stories about how McDonald’s burgers don’t rot, and therefore must not really be food? Someone did an actual controlled experiment on this to figure out why, and it turns out that it only works with the smallest, thinnest burgers, because they dry out before they start to decay. It’s burger jerky. Try it with a thicker McDonald’s burger, or put it in a plastic bag, and it’ll decay just like “real” food. Homemade burgers behave the same way.
