A man from Utah has hung on to a hamburger from McDonald's since 1999. The Huffington Post reported that David Whipple kept the burger that appears hardly aged, even though it's 14-years-old.

Whipple talked to the show "The Doctors" via telephone and explained that the burger was found years ago in his coat pocket and it looks almost the same then as it does now.

The Los Angeles Times reported that Whipple said he still has his receipt from the burger purchased on July 7, 1999 and that he forgot it was in his coat and it was later found by his wife.

Whipple kept the burger and later tried to sell it on EBay but kept it. A pediatrician on "The Doctors," Dr. Jim Sears said "It's called preservatives. If the mold won't eat it, if the fungus won't eat it, bugs won't eat it. Maybe ... we shouldn't be eating it."

However, according to The LA Times McDonald's has a different point of view. The fast food company said in a statement,

"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."

McDonald's continues to add that other foods purchased and kept in dry environments would see the same results.

"For example, without sufficient moisture - either in the food itself or the environment in which it is held - bacteria and mold and associated decomposition, is unlikely," the statement says. "If food is/or becomes dry enough, it won't grow mold or bacteria. In fact, any food purchased from a restaurant or grocery store or prepared at home that lacks moisture would also dehydrate and see similar results if left in the same environment."

McDonald's said in the statement that their hamburger patties are made with 100 percent USDA-inspected beef.

"They are cooked and prepared with salt, pepper and nothing else -- no preservatives -- no fillers. Our hamburger buns are made from North American-grown wheat flour. These are the same foods that people buy every day in their local grocery stores," said the statement.
