"Kellogg takes this situation very seriously and we were shocked and deeply disappointed by this video that we just learned of (Friday). We immediately alerted law enforcement authorities and regulators. A criminal investigation is underway as well as a thorough internal investigation. Our investigation revealed that the video was recorded at our Memphis, TN facility, in 2014. We have confirmed that products that could have been potentially affected were Rice Krispies Treats, Rice Krispies Treats cereal and puffed rice cake products, all of which would be past expiration date.
