<<Disclaimer: Verify this information before applying it to your situation.>> I have not found any problems with the Erehorn - Twice Rice Cereal however I have not tried there poppets - corn allergy. I have two other cereals I use on a regular basis there are: Puffs and Honey by The Breadshop and a hot cereal, Red Bob's Mill - Creamy Brown Rice Farina. It is absolutely delicious. Early on this post somewhat stated that Rice Krispees are gluten-free. I disagree they contain malt. Therefore, rice krispees cereal and rice krispees snack treats are not gluten-free.
