Where I live it is so dry that most foods left on the counter wouldn't decompose in the way people from other parts of the world would expect. If you notice, the burger doesn't have any condiments or toppings on it; and with how thin the burger and bun are it would probably dry out within a couple of days in most non-humid environments. Once dried out decomposition (effectively) stops and food can (for all practically purposes) last "forever" once dehydrated.
On top of that many "normal" foods (like Honey or Christmas Cake) have qualities that make them resistant to mold and bacterial growth, and will last decades before going bad. The fact that this burger lasts so long is not (necessarily) an indicator that it is bad for you.
