Video appears to show man urinating on products at US Kellogg’s

A video appearing to show a man urinating on products at Kellogg's assembly line in the US state of Tennessee in 2014 has just surfaced, prompting a criminal and internal probe by the world's biggest breakfast- cereal maker.

An internal investigation found it was recorded in 2014 at a facility in Memphis, Tennessee, the company said. It potentially affected Rice Krispies Treats, Rice Krispies Treats cereal and puffed rice cake products -- though all would be past their expiration date at this point, CNN reported on Sunday. The video was uploaded on Friday to the site World Star Hip Hop. Kris Charles, a Kellogg's spokesman, said the company is "outraged by this completely unacceptable situation." "Kellogg takes this situation very seriously and is shocked and outraged by this video. We have alerted law enforcement authorities and regulators, and are conducting a thorough investigation," Charles said in a statement.

"Our investigation so far revealed that the video was recorded in 2014 or earlier. We will share more information as we learn more." 

The US Food and Drug Administration has started a criminal investigation, according to CNN  affiliate WREG.
