• Definition

    Brucellosis is an infectious disease caused by contact with animals carrying bacteria called Brucella.

    Alternative Names

    Rock fever; Cyprus fever; Undulant fever; Gibraltar fever; Malta fever; Mediterranean fever

    Causes, incidence, and risk factors

    Brucella can infect cattle, goats, camels, dogs, and pigs. The bacteria can spread to humans if you come in contact with infected meat or the placenta of infected animals, or if you eat or drink unpasteurized milk or cheese.

    Brucellosis is rare in the United States, with approximately 100 - 200 cases each year.

    People working in jobs requiring frequent contact with animals or meat -- such as slaughterhouse workers, farmers, and veterinarians -- are at high risk.
