I used to love cast iron skillets but became concerned when my nickel allergy got so bad.
I couldn't find information on the nickel content of cast iron cookware, so I stopped using it and other metal pots and pans.
Now, I use Pyrex or other glass cookware, and the microwave.
Cast iron is almost pure iron. Nickel is used in alloys to make steel, and is high in content in stainless steels. Pyrex and other glass cookware is almost useless in a survival situation where you have no power or need to bug out. Cooking over an open fire will destroy it.
If you can locate very old (antique) cast iron cookware you should be OK. It is only recent (50 years or so) that alloy metals began to be used in cast iron. I don't believe that nickel is one of the filler metals used in it though.
