A man who posted a video of himself urinating on a conveyor belt of Rice Krispies cereal at the Memphis Kellogg's factory in 2016 has pleaded guilty to tampering with consumer products.

Gregory Stanton, 49, faces up to three years in prison according to an Associated Press report.

Stanton pleaded guilty to the charges last month after being indicted by a grand jury in September.

After the video was posted, Kellogg's launched a full investigation to find the identity of the employee.

The video was posted online in 2016, but was filmed in 2014.

At the time Stanton filmed himself, the cereal plant was had locked out its workers after labor talks between the plant and the workers failed.
