Personally, I love the flavor of peanut butter and I am blessed not to have peanut allergies in my family. But, I do have a young friend in Cloquet named Sydney, who has food allergies, so I immediately passed this info, about Multi-grain Peanut Butter Flavored Cheerios, to her mom, Jennifer.
The fear is cross-contact while processing. General Mills say they have confidence in no cross-contamination. Still, if you have anyone close to you, or you yourself suffer with food allergies, this is important for you to know.
