I don't know what the composition of a cheese slice is but I know I reacted
quickly and it caused LI problems mainly. Today I probably would have an
allergic reaction as well. I know these slices have a lot of whey which is
my problem. However, I don't appear to react to casein. Therefore I would
suggest you consider the possibility that your allergy is more than just
casein.
