Shelf life of hamburger - at least three years

Fasting for all fans of fast food. The photographer from New York, Sally Davis has decided to put an entertaining experiment. She bought at McDonald's french fries and hamburger, which is usually included in the children's menu. Products without refrigeration lain almost three years - 979 days, to be exact - and not a bit spoiled. The company, in response to this action made a statement that the apartment experimenter very dry air. In fact, the problem may lie in the preservatives, GMOs and salt. Interestingly, in the Russian regulations with respect to these components are more stringent than in the US, so that we have such an experiment could end differently.
