The full answer
Skin contact alone generally isn't the concern — ingestion is
Celiac disease is triggered by eating gluten, not by touching it — skin contact with flour or gluten-containing food doesn’t cause the same immune reaction. The real risk from touching gluten is indirect: touching your mouth, food, or utensils afterward without washing your hands.
Why handwashing is still the key habit
This is why handwashing after handling gluten-containing food (like kneading regular bread dough) matters more than avoiding all physical contact — the goal is preventing it from reaching your mouth, not avoiding touch itself.
