Deadline 2008: raw milk under threat in California

Yo California — we've got a problem

Trying to keep it simple and understandable, I would like to give a definition of pasteurization.

Pasteurization is the process of heating milk to 145 degrees Fahrenheit for 30 minutes or heating milk to 160 degrees for 15 seconds and then dropping the temperature down to 50 degrees. Beer and wine are heated to 135 degrees for a few minutes and then cooled down to 40 degrees or lower. This is done to kill harmful bacteria. The process is also used on juices and cheese.

In the 1860’s, Louis Pasteur, a French scientist, invented the process in an effort to make wine and beer last longer on the shelf.
