Which of the following dairy products is made from Grade B milk?

• A. Liquid milk
• B. Yogurt
• C. Ice cream
• D. Cream cheese

Answer: (B)

Yogurt is made from Grade B milk primarily because it is an acidified product, which means that the pasteurization process and the fermentation that occurs during yogurt production can compensate for the quality differences associated with Grade B milk. Grade B milk, while not suitable for fluid milk products, is acceptable for the production of yogurt as it undergoes further processing that ensures safety and quality.

Fluid milk products, such as liquid milk, require Grade A milk due to strict health and safety standards that must be met for consumption. Similarly, ice cream and cream cheese also require Grade A milk to meet quality standards, as they are considered consumer-ready products that have direct implications for public health. In summary, yogurt's unique production process allows it to utilize Grade B milk, making it the correct choice in this context.
