I'm new here, so sorry if this has been asked before. I don't know where to look.
My four year old is very allergic to all nuts excepts Pecans and Walnuts (on blood test). We are going to do a food challenge with those, but I need walnuts and pecans that are not contaminated by other nuts.
Is it safe to get nuts in their shell if they have been touching other offending shelled nuts (peanut, etc?) Are the shells of peanuts, pistachio, etc, carrying allergic proteins that could get onto the walnut/pecan shells during cracking and cause a problem?
Where do you go to get your "nut free" nuts if you are allergic to many but not all peanuts/tree-nuts? Would is be safe to order shelled nuts from Nuts.com?
Thanks!
