Here is from the Mayo Clinic "DefinitionBy Mayo Clinic staff
Brucellosis is an infectious disease that spreads from animals to people — most often via unpasteurized milk, cheese and other dairy products. More rarely, the bacteria that cause brucellosis can spread through the air or through direct contact with infected animals.
Brucellosis symptoms include fever, joint pain and fatigue. The infection can usually be treated successfully with antibiotics. Treatment takes several weeks, however, and relapses are common.
While brucellosis is uncommon in the United States, the disease affects hundreds of thousands of people and animals worldwide. Avoiding unpasteurized dairy products and taking precautions when working with animals or in a laboratory can help prevent brucellosis."
I know, I have it now and have been fighting this horrible stuff for over a year now. It is extremely hard to cure and believe it or not it is around Lakeside. The United States and Canada inoculate their livestock. Mexico doesn't require it.
