Which occupational illness is caused by bacteria?

Brucellosis is an occupational illness that is caused by bacteria, specifically from the Brucella species. This disease is commonly associated with individuals who work in certain professions such as farming, veterinary medicine, and food production, particularly involving livestock. People can become infected through direct contact with animals, unpasteurized dairy products, or inhalation of aerosols containing the bacteria. Symptoms can include fever, sweats, malaise, and muscle pain, and in chronic cases, it can affect multiple systems in the body.

The other options listed relate to different types of health concerns. Hepatitis B is a viral infection affecting the liver, while noise-induced hearing loss and presbycusis are associated with auditory damage but do not arise from bacterial infections. In essence, brucellosis stands out as the condition specifically linked to bacterial origins, highlighting the importance of understanding the causes of different occupational illnesses.
