A Wendy's employee has revealed where the meat the fast food chain uses in its chili comes from and many are shocked by the information.

Fast food restaurants have been long-criticized for their ingredients and every once in a while, something new comes to light that turns many customers off from their favorite fast food place.

Wendy's has been known to have relatively fresh ingredients in comparison with other fast food chains and many across the world love the chain's burgers, chicken and fries.

Some surprising information has turned some customers off from one menu item at Wendy's. According to AWM, an employee has revealed that the meat in Wendy's popular chili is not quite as fresh as some of the chain's other items. The employee claims the ground beef used in the chili reportedly comes from leftover hamburgers.

The chain says that everything it does follows health and safety procedures and that the use of leftover hamburger meat in the chili is to cut down on food waste. Some customers still have their doubts about the practice.

AWM reports that after Wendy's burgers are cooked, the patties are left on the grill until a burger order is placed. If the burgers aren't used in a certain amount of time, they get "discarded" and placed into a container to be refrigerated before they are boiled down and chopped up to be used in a batch of chili.

While there is nothing technically wrong with the fast food chain using day-old meat for chili, some customers are bothered by the use of the leftover meat.

"I thought everyone knew this," one user commented on The Shred's Facebook page. "I worked for Wendy's years ago. When I first found out, I quit eating their chili. I even reported this to the main office and nothing was done. Even called the health dept and nothing was done. AMAZING!"

Other customers see nothing wrong with the practice.

"1 of my first jobs as a teenager was at Wendy's," one reader commented. "The hamburger patties are pressed from fresh,never frozen beef every morning and yes the unsold patties are used to make the chili. Which, in my opinion is a great concept to prevent waste but also makes great chile."

"I've always known that," another user commented "You can easily see the broken up burgers. That's why their chili is so good and different from the rest."
