PMO stands for which regulation?

• A. Public Milk Ordinance
• B. Pasteurized Milk Ordinance
• C. Processing Milk Ordinance
• D. Pasteurized Milk Order

Answer: (B)

The main idea here is recognizing what PMO stands for in dairy regulation and why that term is used. PMO is the Pasteurized Milk Ordinance, the regulatory standard adopted by the U.S. FDA and used by states to govern Grade A milk and milk products. It sets the requirements for pasteurization—including acceptable methods (such as HTST) and the time-temperature needs—along with sanitation, equipment, testing for pathogens, and the overall regulatory framework for safety and labeling. This makes Pasteurized Milk Ordinance the correct interpretation of the acronym, as it represents the formal regulatory document that guides how pasteurized milk is produced, processed, and protected across interstate commerce. The other options don’t reflect the established regulatory naming: there isn’t a commonly used “Public Milk Ordinance,” and terms like “Processing Milk Ordinance” or “Pasteurized Milk Order” aren’t the standard designation used in dairy regulation.
