Answer

The global burden of human brucellosis remains enormous. The organism causes more than 500,000 infections per year worldwide. The annual number of reported cases in United States (about 100) has dropped significantly because of aggressive animal vaccination programs and milk pasteurization. Most US cases are now due to the consumption of imported unpasteurized dairy products from Mexico. Approximately 60% of human brucellosis cases in the United States now occur in California, Texas, Arizona, and Florida.
