PORTLAND, Ore. (AP) - Kellogg says that higher-than-normal amounts of certain chemicals in its package liners caused the unusual smell and flavor that prompted a recall of 28 million boxes of its cereal in late June.
The food maker recalled Apple Jacks, Corn Pops, Froot Loops and Honey Smacks after about 20 people complained. Five reported nausea and vomiting.
The company says it has identified chemicals normally present in packaging called hydrocarbons as the source.
The Food and Drug Administration said it is reviewing Kraft's information and conducting its own risk assessment.
Kellogg Co. is based in Battle Creek, Mich.
