   4. (4) Soybean meal, flakes or pellets or another vegetable meal, flake, or pellet that have been extracted with trichloroethylene or other chlorinated solvent.
   5. (5) Sulfur dioxide, sulfurous acid, and salts of sulfurous acid that are used in or on feeds or feed ingredients that are considered or labeled a significant source of vitamin B₁ (thiamine).

2. Section 2. A screening or by-product of grains and seeds containing weed seeds used in commercial feed or sold as commercial feed to the ultimate consumer shall be ground fine enough or otherwise treated to destroy the viability of the weed seeds so the finished product contains:
