A recent, viral TikTok showed how a 24-year-old McDonald's meal still looked good as new, even through its aging. Now, McDonald's is explaining why the burger and fries didn't decompose as one might expect.

The TikTok user was shocked to find that a McDonald's burger and fries kept in a shoebox in her closet for more than 20 years had remained largely unchanged, even after much time had passed.

The post quickly gained the attention of hundreds of thousands of people.

While the burger giant did not mention the exact TikTok in question, they posted in their newsroom about why a meal from their restaurant might be able to withstand the test of time.

"In the right environment, our burgers, like most other foods, could decompose," the post began.

However, they continued on to say that moisture is needed in order for that process to really take place. "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," the post continued.

The fast food chain also urged people enthralled by the years-old burgers to "look closely." "The burgers you are seeing are likely dried out and dehydrated, and by no means 'the same as the day they were purchased.'"

According to the post, there are "no preservatives or fillers" in the patties.
