The quality classification of raw milk for manufacturing purposes from each producer shall be based on an organoleptic examination for appearance and odor, a drug residue test, and quality control tests for sediment content, bacterial estimate and somatic cell count. All milk received from producers shall not exceed the Food and Drug Administration's established limits for pesticide, herbicide and drug residues. Producers shall be promptly notified of any shipment or portion thereof of their milk that fails to meet any of these quality specifications.
