NEW YORK (CNNMoney.com) -- Kellogg Co. is recalling 28 million boxes of several popular cereals due to an unusual flavor and smell, the company said Friday.
The company said potential for serious health problems is low, but an "uncharacteristic off-flavor and smell coming from the liner in the package" could cause temporary symptoms including nausea and diarrhea.
Only boxes with the letters "KN" following the "better if used before" date are included in the recall. Products with "KM" are not being recalled, nor are any products in Canada.
In a statement, Kellogg Chief Executive David Mackay apologized to consumers and said the company is "working diligently to ensure that the affected products are rapidly removed from the marketplace."
