Humans are usually infected by ingesting food made from infected animals, and B. burgdorferi can also be contracted by eating raw meat or meat that has been fully cooked. Farmers, laboratory workers and slaughterhouse workers can be infected with Brucella by inhaling aerosols containing Brucella, and Brucellosis can also be caused by entry into the body through skin wounds, conjunctivae, etc.
