PMO governs the sale of Grade A milk and milk products in which commerce contexts?

• A. Interstate and intrastate
• B. International
• C. Domestic only
• D. Local markets only

Answer: (A)

The PMO, or Pasteurized Milk Ordinance, provides the rules for Grade A milk and milk products that apply to both crossing state lines and moving within a state. It’s a model regulation used by state dairy programs to ensure pasteurization, sanitary practices, testing, and labeling so milk that travels between states or stays inside a state meets consistent safety standards. International trade isn’t governed by the PMO, and limiting to domestic-only or local markets would miss the essential coverage of shipments that occur across state boundaries. So the correct scope is interstate and intrastate commerce.
