When Eduard Nitz and Cacey Dean were teenagers in 1995, they didn’t expect to become custodians of the world’s oldest McDonald’s burger. The burger was left in Eduard’s care by a friend who never returned to claim it. Since then, the burger has been carefully stored between family members.
Nearly 30 years later, this so-called ‘Senior Burger’ hasn’t rotted and hasn’t grown mold. According to the owners, the burger is just “too old for mold.” It became rock hard over the years, losing its original softness and juiciness but remaining surprisingly intact.
The burger drew public attention about a decade ago when the men created a Facebook page challenging it to out-like Kanye West’s pages. The story went viral, leading to fan art and music inspired by the burger. Eduard and Cacey are now working on giving the burger an AI personality that fans can interact with.
Nutritionists explain this preservation by the high salt levels in McDonald’s food. The men also confirm that McDonald’s is informed about the burger whenever it’s featured publicly.
