What are screenings?

Screenings are a mixture of mill or elevator run, or a combination of varying materials obtained in the process of cleaning grain, seeds, or both.

• The mixture typically contains light or broken grain or seed, noxious weed seeds, hulls, chaff, joints, straw, elevator dust, floor sweepings, sand and dirt.
• WSDA has the authority to adopt rules that designate which noxious weed seeds shall be controlled in screenings, and the amount of these seeds to be permitted in screenings.
