Hi Bea1,

I don't think we need to worry about smelling gluten, but free flying flour dust can be a problem for people with celiac disease, gluten sensitivity, or wheat allergy. Cross contamination is also an issue... if gluten containing flour dust, crumbs, etc., land on other food we eat.

Gluten is even found in drywall mud, and some people have become symptomatic from inhaling drywall dust when remodeling, etc.

Different people react differently to small exposures like that, but the idea is to limit those small exposures as much as possible. They add up.
