Response to myth that McDonald’s burgers do not decompose

In the right environment, our burgers, like most other foods, could decompose.

But, in order to decompose, you need certain conditions – specifically moisture. Without sufficient moisture – either in the food itself or the environment – bacteria and mold may not grow and therefore, decomposition is unlikely. So if food is or becomes dry enough, it is unlikely to grow mold or bacteria or decompose.  Food prepared at home that is left to dehydrate could see similar results. Look closely, the burgers you are seeing are likely dried out and dehydrated, and by no means “the same as the day they were purchased.”

The reality is that our burgers are made only with 100% USDA inspected beef. There are no preservatives or fillers in our patties and the only thing ever added is a touch of salt and pepper on the grill.
