Kellogg has launched a criminal investigation after a video surfaced online appearing to show an employee urinating on a factory assembly line.

The video was uploaded to the website World Star Hip Hop last Friday.

In a statement to, the company said Kellogg learned of the video on that same day, and immediately alerted regulators and law enforcement authorities.

"A criminal investigation is underway as well as a thorough internal investigation," the statement said.

According to the company, the video was recorded at its facility in Memphis in 2014.

Potentially impacted products include Rice Krispies Treats, granola clusters used in a more than one product, and a few other puffed rice treats Kellogg no longer makes, the statement said.

"It is important to note that any products that could have been potentially impacted would be very limited and past their expiration dates," the statement said.

"Food quality is of the utmost importance to Kellogg Company. We are outraged by this completely unacceptable situation, and we will work closely with authorities to prosecute to the full extent of the law."
