McDonald's Hamburger Not Rotting Issue: Fast Food Chain Has Something to Say

A number of photo news against McDonald's foods was circulating online saying that their meals didn't even rotted even if years have passed. Hence, the world's largest chain of hamburger fast food restaurant defended themselves by saying that the issue has been longed answered on their "frequently asked questions" section.

"Food needs moisture in the air for mould to form," McDonald's explained, according to The Independent. A program director at the University of Guelp's department of Food Science and Quality Assurance Dr Keith Warriner added: "The reality is that McDonald's hamburgers, French fries and chicken are like all foods, and do rot if kept under certain conditions."

"Essentially, the microbes that cause rotting are a lot like ourselves, in that they need water, nutrients, warmth and time to grow," he added. "If we take one or more of these elements away, then microbes cannot grow or spoil food."

Furthermore, in a given example, a McDonald's hamburger patty loses its water when steamed and throughout the cooking procedure. The bun, on the other hand, is made out of bread, but its moisture was also lost once heated and toasted.

Hence, upon cooking, McDonald's hamburger becomes "fairly dry," which made it not decomposing. "When left out open in the room, there is further water loss as the humidity within most buildings is around 40%. So in the absence of moisture or high humidity, the hamburger simply dries out, rather than rot," Warriner continued.

In another experiment made by Serious Eats, he clearly said that "McDonald's burgers don't rot because they dry out. Some people believed that the fast food's burger can be compared to saltine crackers, beef jerky, hardtack, croutons, dried beans and any other nutrient-foods that are being stocked on the shelves.

It is not artificial and nasty, neither filled with chemicals nor has no nutrition. It has something to do with its preparation and water activity, which made it dry, lose its moisture and not rot; so people don't have to be scared of.
