The US Food and Drug Administration (FDA) has opened a criminal investigation after a video of a man urinating on a Kellogg factory assembly line surfaced online, the company announced.

The video, which was uploaded to worldstarhiphop.com on Friday, shows a man urinating on cereal as it comes off the assembly line. It then pans to a sign featuring the Kellogg’s logo.

An internal investigation by the food giant found that the video was recorded in 2014 at a factory in Memphis, Tennessee.

A statement from the company said products “potentially affected” by the urine would be past their expiration dates by now.

Battle Creek-based Kellogg on Monday apologized to customers over a video in which a man urinated into a Rice Krispies Treats production line.
