Have you ever heard people talk about dairy foods in terms of what grade they are? For example, milk is often labeled "Grade A." You may have wondered what this means. Depending on how a dairy farmer runs his/her operations, the milk is labeled a certain grade. Grade A is the term used for the highest quality milk, Grade B for the next level, and so on. In order for a farmer's milk to be considered Grade A, certain rules set by the government must be met. Inspectors come out to the farm to make sure that all of the equipment and milk are kept sanitized and the cows are in good condition. Thus, a farmer must spend time making sure that everything is clean.
