What quality control measure is taken by Federal Milk Market Administrators for Grade A milk?

The correct answer highlights the importance of maintaining safety and quality standards for Grade A milk, which is crucial for consumer health and market integrity. Federal Milk Market Administrators implement systematic testing for composition and auditing records to ensure that milk meets specific quality standards. This includes evaluating factors like butterfat content, protein levels, and the presence of any contaminants.

Routine testing helps in verifying that the milk aligns with federal guidelines and state regulations, thereby ensuring that consumers receive a product of consistent quality. Auditing records from producers and processors also plays a vital role in tracing back any issues to their origin, which strengthens the overall quality assurance process.

While taste testing and marketing strategies may be relevant to the dairy industry, they do not directly address the stringent measures necessary for ensuring compliance with safety and quality standards that Grade A milk must meet. Automatic cooling during transportation is important for preserving milk quality, but it's one part of a larger overall quality control system rather than a comprehensive measure on its own.
