A soft-spoken Minnesota farmer was cleared of violating state laws for distributing raw milk Thursday, a verdict advocates for such foods called their first major legal victory.

After a three-day trial and more than four hours of deliberation, a Hennepin County jury found Alvin Schlangen not guilty of three misdemeanor counts of selling unpasteurized milk, operating without a food license and handling adulterated or misbranded food.

The trial highlighted a deep national divide between raw milk advocates who contend unpasteurized dairy products can relieve allergies and prevent illness and public health officials who warn that raw milk can cause serious and sometimes fatal diseases, such as E. coli, salmonella and listeria.
