Kellogg's is recalling four varieties of breakfast cereals due to a substance that can make the cereal taste and smell not so good. While the substance is considered harmless, some people may be sensitive to it and suffer from short bouts of diarrhea and nausea.
Kellogg's has more information in their consumer alert.
