Brucellosis
Brucellosis is a disease caused by several species of the Brucella bacterium. The disease can affect livestock; however, Canadian cattle have been declared brucellosis-free since 1985. Brucellosis may be transmitted to people when they consume unpasteurized/raw dairy products or are in close contact with infected animals. Those who work with livestock are at greater risk of infection. Human infections in Ontario are rare. Symptoms of infection include fever, sweats, fatigue and headaches.
