Nickel allergy

I mentioned an infant with horrible skin irritation awhile ago and I just want to post an update.  It is looking like it's a nickel allergy.  My friend asked me to hit the internet and do some research and what I discovered is that, while contact dermatitis from nickel (earrings, fake jewelry, etc) is not uncommon, a small percentage of people are actually allergic to ingested nickel as well.  Things grown in the ground tend to be higher in nickel than animal products.  AthenaAllergy.com is a great resource for anyone suffering with nickel allergy.
