The Food and Drug Administration has opened an investigation into video allegedly showing a man urinating on a Kellogg’s factory assembly line in Tennessee. The footage was recorded at a Memphis factory in 2014, the company said, adding that Rice Krispies Treats and granola clusters may have been affected. A representative said the company learned of the film on Friday and immediately informed law enforcement. The man in the video hasn’t been identified yet. “We are outraged by this completely unacceptable situation, and we will work closely with authorities to prosecute to the full extent of the law,” Kellogg’s said, adding that any affected products are likely past their expiration dates at this point.
