While it may seem like the sensible idea to throw food away after several weeks, months, or even years – one woman has proven just how far she went with her McDonald’s hamburger and French fries.

A Tiktok user recently took to social media to share her grandmother’s decades-old possession that she keeps hiding away in a shoe box in her closet.

Aly Sherb showed her grandma pulling open the 24-year-old wrapper to reveal a slightly old looking hamburger that she purchased in 1996.

She starts off the video by showing the bag’s advertisement for US Nascar races in 1996.

She then takes out the fries, which she says look like they could have fallen into a seat “a month or so ago” and says that they “never rotted or decayed.”

The woman then shows the burger that she purchased in its original wrapping, then pulls out the burger.

The bun and burger appear to never have rotted or decayed either.

The video finishes with her saying, “24-year-old hamburger, not sure what would happen if you ate it though.”

Anne Christensen, director of Field Brand Reputation for McDonald’s, told Fox News: “In the right environment, our burgers, like most other foods, could decompose. But, in order to decompose, 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. Food prepared at home that is left to dehydrate could see similar results. Similarly, this particular burger is likely dried out and dehydrated, and by no means the same as the day it was purchased.”
