MEMPHIS - A man who posted video of himself peeing on a Kellogg's cereal conveyor belt in Tennessee has pleaded guilty.

Gregory Stanton, 49, of Memphis, pleaded guilty to one-count of tampering with consumer products, U.S. Attorney D. Michael Dunavant announced on Tuesday.

The video, uploaded to the dark web in 2016, depicts Stanton urinating on a conveyor belt at the Battle Creek-based company's manufacturing plant in Memphis in 2014.

A federal grand jury returned an indictment against Stanton on Sept. 11. The U.S. Food and Drug Administration also investigated the matter. Stanton pleaded guilty before U.S. District Judge Jon P. McCalla on Nov. 30.

"American citizens and consumers rely upon food manufacturers engaged in interstate commerce to provide them with safe and consistent products," Dunavant said in a statement. "Unfortunately, this defendant betrayed that trust by tampering with and tainting food products."

Stanton is set to be sentenced on Feb. 28, 2019. He faces up to three years imprisonment; three years supervised release and a $250,000 fine.

"Maintaining the safety and wholesomeness of the U.S. food supply is a critical priority for the FDA, and the agency will work with food producers to identify steps that can be taken to remediate incidents that may implicate food safety," said Robert M. Hiser, Acting Special Agent in Charge, FDA Office of Criminal Investigations' Miami Field Office.

"Today's announcement should serve as a clear reminder that the FDA will not tolerate illicit tampering activity in our nation's food supply."

Kellogg's said in a statement to WMC-TV in Memphis that it is "pleased that the responsible individual was brought to justice."
