I don't get it either. I'm just thankful that I don't have to worry about it, LOL. I haven't heard of anyone having anaphylactic reactions to strawberries or tomatoes but I know that for a lot of kids they cause hives. (That's anecdotal though!) Some research says that kids prone to allergies should be exposed to allergenic foods earlier. However as a parent I just couldn't see myself doing that if I had a history of allergic reactions in my family... It's a difficult decision for some.
