A resident of Utah recently sent a McDonald's hamburger patty to the TV show The Doctors that was over 14-years-old.

David Whipple had purchased the burger on July 7, 1999, and initially kept it in his possession to show his friends how the enzymes in it work.

However, he soon forgot about it and his wife found the patty inside a paper bag in one of his jacket pockets two months later.

Shockingly, Whipple discovered that the burger's condition remained virtually unchanged, according to Yahoo!.

Now, some 14 years after its original purchase, he's continued to keep the patty, which still has no mold or fungus on it. The only difference in the patty is that the pickle on top of it disintegrated.

For any of his naysayers, Whipple actually kept the original receipt as proof of when and where he bought the meat. As of late, he used it to make a point out the consequences of not eating healthy to his grandchildren.

Whipple isn't the first person to evaluate the condition of the McDonald's hamburger over the course of time. New York City artist Sally Davies launched the Happy Meal Project on her Flickr page, where she posts the same burger and fries from a Happy Meal on a daily basis.

Also, blogger Karen Hanrahan did a similar experiment with a McDonald's patty, using it for over 16 years for a parental teaching class on avoidance of junk food.

The site reported that McDonald's had responded with the following statement on the matter:

"McDonald's hamburgers are freshly prepared in our restaurants. While not knowing the conditions in which the food was kept in this specific claim, what is scientifically known is that in bacteria and mold only grow under certain conditions."
