What's older than Google, Netflix, and Tom Holland? A Quarter Pounder from McDonald's that's been traveling Australia for a quarter of a century. As 7News.com.au reports, the hamburger was purchased from a McDonald's restaurant in the mid-1990s, and roughly 25 years later it shows no signs of rot—a fact that's somehow more repulsive than the alternative.
Adelaide residents Casey Dean and Eduard Nitz bought the Quarter Pounder with Cheese in 1995 with their friend Johnno who was visiting from out-of-town at the time. Unable to finish the patty, Johnno asked his friends to hold on to it for him until his next visit.
He couldn't have guessed the implications of his request. After the meal, Nitz tossed the boxed-up hamburger into his cabinet at home where it would sit until he moved out. The Quarter Pounder remained in pristine condition, so instead of throwing it away, Nitz handed it off to his sister before going to live overseas. She ended up bringing it with her on various moves across the continent. Then, in 2015, Casey Dean became the official guardian of the indestructible sandwich.
As it nears its 25th birthday, the Quarter Pounder is still far from the nasty, moldy mess you'd expect it to be. That's because McDonald's hamburgers aren't very moist to begin with, so they dry out faster than they can decay. It's the same reason beef jerky can last so long; in other words, there are no mystery chemicals at play.
