I bought these products and had not noticed a "warning" on backside... Since when does ingles make a dollar off consumer with such a product that states it contains a chemical (acrylamide) known to cause cancer. And knowingly (fda) has allowed since a certain amount is ok... That's like saying a little cyanide won't kill you the first time! Companies, distributors, importers, etc... Simply do not care what havoc they create for the "little" people if they make a dollar... And trust me, ingles makes that dollar! Since when does one box of honey grahams cost $4.98... But, if you buy one get another... That's a joke, one box does not cost $4.98... Trick advertising.
