Whey contains the latter two and is casein free. We have assumed that my son is not only allergic to casein but also to the "lacto's". We have never been allowed allergy testing as we are on an HMO and his reactions are not, at this time, anaphylactic. He reacts to the cheeses somewhat and whey containing products (such as margarine, many breads) much more so. He only recently began having a reaction to sodium sterol lactilate in breads. We avoid everything milk related, even butter (although I have been told countless times that it contains no milk protein). Whey on innocent looking french fries makes me cringe, especially when the managers don't even know it is there. P.S. We were traveling in MN when we found Hardees, we are in IL but don't normally eat fast food other than McDonald's (where I know what is 'safe' and what is not for all of our various food allergies).
