When called to a farm with signs of respiratory disease, what is the proper inspection order?

• A. Only the sick horse
• B. All other horses on the premises first, then the sick animal
• C. Both the sick horse and the rest of the animals on the premises, but the order is not important
• D. The sick animal first, then check all other horses on the premises

Answer: (B)

The main idea is to protect healthy animals and personnel by controlling disease spread through proper biosecurity during field inspection. By surveying all other horses on the premises first, you can gauge how widespread the issue is, identify potential contacts and housing that may need isolation, and implement initial precautions before approaching the contagious source. This sequencing minimizes the chance of transferring pathogens from the sick animal to healthy animals and helps you set up appropriate PPE, equipment separation, and isolation measures before handling the ill horse. Inspecting the sick animal first or examining them all without a careful order increases the risk of cross-contamination and makes it harder to manage the outbreak effectively.
