Preservatives play a vital role in keeping the food safe from getting spoiled for a longer time. But can they preserve food for as long as six years? It probably can. We don’t say so but someone on Facebook is claiming the same.

Recently, a Facebook user Jennifer Lovdahl posted pictures of fast food chain McDonald’s burger and fries which was kept for six years. She says that the food looks the same as it was six years ago.

She wrote:

“It’s been 6 years since I bought this “Happy Meal” at McDonald’s. It’s been sitting at our office this whole time and has not rotted, molded, or decomposed at all!!! It smells only of cardboard. “

Jennifer, who runs a health firm in Alaska, says that the experiment was done solely to show their patients about how unhealthy these foods are because of the excessive amount of preservatives.

Here’s the Facebook post:

However, this is not the first case of its kind. 

In 2014, a 2-year-old McDonald’s Happy Meal was doing the rounds on the internet for not getting spoiled in Nebraska. The very next year there were reports of Mc Donald’s food not getting mouldy in six years claimed by an Icelandic man. He had purchased the last-ever McDonald’s meal sold before the closing down of the chain in 2009.

There most shocking claim was made by a man from Utah, who  claimed that a burger remained the same for 14 years and still looks the same.

McDonald’s Canada posted an alternative explanation on its Q & A page following a customer;s question on why the company’s burgers didn’t get affected.

Here’s the explanation:

“There have been a lot of online videos and photos touting the fact that when left out for an extended period of time, a McDonald’s hamburger does not rot and that this is because they are laden with chemicals. 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. If we take one or more of these elements away, then microbes cannot grow or spoil food.In the example of a McDonald’s hamburger, the patty loses water in the form of steam during the cooking process. The bun, of course, is made out of bread. Toasting it reduces the amount of moisture. This means that after preparation, the hamburger is fairly dry. 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.With moisture loss, we take away an element required by microbes to grow and cause spoilage. So to spoil a McDonald’s hamburger, we simply need to prevent the moisture loss. This can be done through wrapping it in cling film to prevent moisture from escaping, or storing it within a high humidity environment, such as a bathroom (notice black mould on your bathroom windows but not in your bedroom). If you try doing the same experiment with a homemade burger with similar moisture content as a McDonald’s hamburger and under similar conditions, you’ll probably get the same results.”
