Pasteurization (food gone bad)

Pasteurization, a process named in honor of French chemist, Louis Pasteur, uses heat to destroy pathogenic microorganisms in foods and beverages such as milk, cheese, fruit juices, and canned goods. Its intended use is to increase the shelf-life and stability of many foods.  

For your initial post, define the pasteurization process. Do you think pasteurization necessary? What about countries that don’t use pasteurization? How are they able to safely consume products like unpasteurized dairy products? Do you think raw milk and dairy products should be more or less available?
