Milk is an important part of many people's diet. Farmers who raise dairy cows are careful about who they hire to handle the milk. Their cows are tested regularly and once the milk is taken from the cows, it is filtered and cooled at the milk house. It is pumped into tanks and shipped to a milk plant where it is pumped into large holding tanks. At this location, tests ensure its quality and cleanliness. Pasteurization is the process to make milk safe. This process heats the milk to a temperature high enough to kill bacteria. At this time the milk is cooled quickly, stored, placed into smaller containers, shipped to various locations, and then placed on the shelf for purchase. Which is the main idea of this passage? O 1.
