Name a common zoonotic disease encountered in farm environments.

• A. Salmonellosis (Salmonella)
• B. Rabies
• C. Tetanus
• D. Lyme disease

Answer: (A)

Zoonotic diseases are infections that can pass between animals and people. On farms, people regularly handle animals, feed, water, and equipment, creating opportunities for pathogens to move from animal waste into humans. Salmonella lives in the intestines of many farm animals and is shed in feces, so contact with animals, contaminated surfaces, or contaminated food or water—especially with poultry, eggs, pork, or dairy operations—can readily cause infection in people. That frequent, direct line of contact makes salmonellosis a common farm-related zoonosis and the most likely choice in this context. While rabies, tetanus, and Lyme disease are important zoonoses in broader settings, they are less commonly encountered on farms in everyday scenarios: rabies risk centers on bites from infected animals, tetanus isn’t transmitted from animals to humans and is tied to wound contamination, and Lyme disease is tick-borne and less tied to routine farm activities than Salmonella.
