There are several steps to starting a Grade "A" Dairy Plant.

  • Read "Summary of Requirements for Michigan Dairy Processing Plants" DY 378

  • Contact the Lansing Office at 800-292-3939 to locate the inspector for your area.
  • Work with your local inspector to review construction plans, sanitary piping plans and other Grade "A" Pasteurized Milk Ordinance requirements.
  • Complete Grade A Dairy Plant Application.
  • Producer Security is required for all Grade "A" plants that are a first receiving point for raw milk that is going to be processed at that facility. Because the plant takes title (possession) of the raw milk for processing, the plant is responsible for it and must have producer security prior to any shipments being made into the plant. Also prior to any shipments being received at the plant, the Lansing office must approve all forms of producer security.
  • Any changes to plant plans or operational procedures should be reviewed with the local inspector before implementation.
  • Plan review must be completed with your inspector prior to issuance of a dairy plant license. 
  • Have an approved Grade "A" Milk Plant inspection done by your local inspector.
