File this under personnel security: A video has surfaced online that allegedly shows a man urinating on a Kellogg’s cereal assembly line in Memphis, Tenn. The incident graphically illustrates the damage a malicious employee is capable of wreaking, underscoring the need for careful employee vetting as part of any food defense program.

A Kellogg spokesperson told Memphis TV station WREG that the incident happened in 2014, during the same time the company and workers were locked in a labor dispute and employees were locked out. The fact that the video has suddenly become public is probably not a coincidence, as Kellogg announced two days ago that the company was pulling advertising from far-right website Breitbart.com, sparking a backlash and calls for a boycott of Kellogg’s products. The video was uploaded by worldstarhiphop.com.

Products that could potentially have been affected were Rice Krispies Treats, Rice Krispies Treats cereal, and puffed rice cake products. All would be well past their expiration date. The Food and Drug Administration has started a criminal investigation, and Kellogg has initiated an internal investigation.

“Food quality is of the utmost importance to Kellogg Co.,” the company said in a prepared statement. “We are outraged by this completely unacceptable situation, and we will work closely with authorities to prosecute to the full extent of the law.” READ MORE
