A criminal investigation has been launched after video emerged appearing to show someone urinating on an assembly line at a Kellogg factory.
The breakfast cereals maker said it learned of the graphic footage on Friday and “immediately” alerted law enforcement and US regulators.
“We are outraged by this completely unacceptable situation, and we will work closely with authorities to prosecute to the full extent of the law,” the company said in a statement.
The US Food and Drug Administration’s Office of Criminal Investigation is looking into the incident, Kellogg said.
The company said its own investigation determined the video was recorded at its Memphis, Tennessee, factory in 2014.
The footage posted online appeared to show a man urinating on the assembly line, before panning to a sign with the Kellogg logo.
The company said the food items potentially impacted “would be very limited and past their expiration dates”.
Kellogg has not identified the person in the video, a spokeswoman said.
