My son has a dairy allergy and I've occasionally give him deli turkey with no problems. Not even thinking it may contain a dairy product. Today at lunch I gave him some and his whole face broke out in hives so I quickly looked at the ingredients (which I obviously should have done before) and sure enough, nonfat dry milk it the 3rd thing listed!
I called the allergist, she said to give him Benadryl and watch his breathing. The hives went away quickly and so far no vomiting, swelling, etc. The first time he reacted to dairy he had hives and vomiting. So now we have an Epi Pen and I have it standing by today... ugh, I get bad mom of the day award.
I guess the point of my post is to watch out for the ingredients in deli meat! No more deli meat for my guy, as now it also made me think of the cross contamination going on at those deli counters.
