Dairy Clerk Question:

Pasteurization is a simple, proven and effective process, approved by the Food and Drug Administration that kills potentially harmful bacteria without affecting the taste or nutritional value of milk. During pasteurization, the temperature of milk is raised to at least 161° Fahrenheit for 16 seconds and then rapidly cooled. Pasteurization extends milk's shelf life and destroys harmful bacteria. Ultra-high temperature pasteurization, where milk is heated to 280° Fahrenheit for more than 2 seconds, is used to extend shelf life in some dairy foods.
