Back to the food ingredient and food allergy question. My son, who is now 30, was born with anaphylactic food allergies to all milk, egg, tree nut, peanut. Even a tiny amount of whey or sodium caseinate, which are common and at that time not listed as ingredients, would require immediate epinephrine.
He almost died after eating Golden Grahams, which did not list the butter based flavoring because the FDA did not regulate flavoring. We were part of the class action suit that got the congress to require listing at least major allergens. Nonetheless, we had to check the food labels every single time we bought any food item because they change. And bread, even on the same label, may shift ingredients by factories.
I would never count an ingredient list to be accurate, unless I read the one on the packaging of the actual food item, if you are dealing with anaphylactic allergies. In particular on a train where getting to an ER after the initial 2 self administered epi-pens might be impossible.
I am not defending shoddy customer service, but food ingredient lists are not static, and are out of the control of purchasers.
