A viral video has re-emerged of a KFC location's unsanitary practices. The video, which has attracted more than 5.2 million views and more than 12,000 comments on YouTube, shows an employee recording two co-workers as they prepare to close an undisclosed U.S. restaurant.

The video first appeared on YouTube in January 2013, but it continues to resurface often, according to a representative of the restaurant.

"This video was filmed many years ago and does not reflect our standards or food handling procedures," a KFC spokesperson told International Business Times Friday. "It, unfortunately, resurfaces online from time to time, often tagged as various locations inaccurately. The actions of those former employees was unacceptable."

The recording took place at a dual KFC and Taco Bell location. The Taco Bell's practices, however, were not revealed in the video. The KFC spokesperson wouldn't confirm the location of the incident to IBT.

Employees are seen reusing macaroni-and-cheese cups, freezing green beans in previously used water and leaving fried chicken overnight to be sold the next day.

"What do you want the world to know about KFC and Taco Bell?" a female employee can be heard asking behind the camera.

"I want the world to know this is what we do after we close," a male employee responds, as he dumps green beans into containers of dirty water. "Then we feed it to the customers.

"It's cross-contaminated."

The video also shows a batch of green beans had been sitting in the old, unclean water for three to four days, according to one employee.

The workers revealed the macaroni and cheese undergoes the same process as the green beans. The contents are placed in containers and then placed in a freezer instead of being thrown out. The leftover green beans and macaroni-and-cheese containers are later reused in future sales.

The chicken, however, is more problematic. The KFC workers state that the fried chicken is resold to customers with mildew and mold on it. The group also commented on the chicken's foul odor, saying, "h--- yeah, that stinks."

KFC, which according to its website has "over 20,500 outlets in more than 125 countries," has been the subject of previous controversies. The restaurant chain came under fire for selling antibiotic-laden chicken to customers in April. KFC would later pledge that its locations will sell chicken that has been raised without potentially hazardous antibiotics by the end of 2018.

KFC was hit with a $20 million dollar lawsuit after a New York customer alleged that the restaurant was underfilling the buckets, which the customer claimed was a misrepresentation from its televised advertisements. Plaintiff Anna Wurtzburger, 64, alleged that this was "false advertising" of the Family Fill Up deal.

People for the Ethical Treatment of Animals launched a campaign in 2001 against KFC through a website called, Kentucky Fried Cruelty. The website is populated with current news about the company's alleged wrongdoings, including lambasting the Louisville, Kentucky-based company for "launching a chicken-flavored edible nail polish."

"KFC's own animal welfare advisors have asked the company to take steps to eliminate these abuses, but KFC refuses to do so," PETA wrote on its website. "Many advisors have now resigned in frustration."

Celebrities like Pamela Anderson, Ryan Gosling and Sir Paul McCartney have also spoken out against KFC.
