Question:
Sometimes oats In the US get white and powdery or are only slighty powdery. Obviously the insects are not even visable with a jewelers loup….is this a concern? Or only when its progressed to issues of clumping and webbing.
Answer:
According to R’ M. Vaye shlit”a it is only when there are bugs, or webbing in the package, but not just a little powder. Please see the following link https://dinonline.org/Bedikat/oatmeal-rolled-oats-quick-oats/
