Several Kellogg’s products manufactured in 2014 were likely tainted after a man urinated on cereal products on an assembly line in Memphis, Tennessee. The incident was discovered only on Friday after a video was uploaded on the Internet.

The Kellogg products affected were not Corn Flakes, but Rice Krispies, granola clusters used in other cereals and puffed rice treats. By now, these products have either been consumed or expired, reports the New York Daily News.

The police is now investigating the incident which was shot during a major labor dispute affecting the cereal maker, according to WREG-TV.

The US Food and Drug Administration has stepped in and wants to know who the person is behind the camera who shot the video and the man who peed on the assembly line. Kris Charles, Kellogg’s spokesperson, says the company is taking the situation very seriously and is shocked and deeply disappointed by the video.

“We immediately alerted law enforcement authorities and regulators. A criminal investigation is underway as well as a thorough internal investigation,” says Charles who stresses that Kellogg places utmost importance on food quality.

The 43-second video, uploaded on World Star Hip Hop, has become viral with more than 450,000 views as of Sunday.

In a forum on Researchgate, Jerry Miller of Texas Children’s Hospital, explains that while urine is normally sterile of bacteria, viruses are shed in urine at certain times during and after viral illnesses. But Zsolt Torok, from the Danube National Institute for Research and Development, notes that in humans, faeces and urine are considered waste, but in some animals such as tortoise, it consumes faeces of foxes and jackals as its source of calcium to have strong shells.
