The "food" you see pictured here is nearly two years old.
As Business Insider reports,
A Michigan chiropractor has been saving a Taco Bell chicken taco and McDonald's cheeseburger with fries for two years, and none of the items have appeared to rot. Dr. Jacqueline Vaughn purchased the meals in early 2013 and put them on display in her office, Vaughn Chiropractic, in Waterford, Michigan.
The meals have remained there ever since, sitting uncovered next to the patient sign-in sheet. None of the food has grown mold or started to smell, according to Jessica Freed, a chiropractic assistant who works in the office.
The gimmick is, of course, to remind patients of the dangers of eating fast food, though Business Insider cites a tartly-worded McDonald's rebuttal regarding the amount of preservatives in its food:
The reason our food may appear not to decompose comes down to a matter of simple science. In order for decomposition to occur, 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 ... the burgers you are seeing are likely dried out and dehydrated.
No response from Taco Bell was mentioned, but this close-up of the curiously un-aged two-year-old taco speaks 1,000 words, and one of them is "Ewwww."
