I'm anaphylactic to nuts, will touching walnut wood and eating afterwards cause an allergic reaction?

Nut-anaphylactic car enthusiast here. I touch walnut wood in luxury cars on the dashboard, the shifter, etc. Will touching walnut wood and eating afterward cause an allergic reaction?

The allergen in the tree pollen is a specific protein found in the pollen and not in the wood. Touching the wood of the same tree would not pose a risk.
