All of the following are important biosecurity measures during the investigation of a vesicular disease outbreak EXCEPT:

• A. Notify the media so they can tell the public to stay away from the farm
• B. Use personal protective equipment (PPE)
• C. Clean and disinfect equipment used
• D. No movement on or off farm

Answer: (A)

The main idea is identifying actions that directly reduce the chance of spreading disease during an outbreak investigation. On-farm biosecurity focuses on protecting people and animals from exposure and stopping transmission through contaminated gear, equipment, and movements.

Personal protective equipment is essential because it creates a barrier between investigators and potentially infectious material, preventing both acquiring the pathogen and carrying it to other sites. Cleaning and disinfecting equipment and surfaces removes or inactivates any virus present, stopping fomites from spreading the disease. Controlling movement onto and off the farm is crucial to prevent vehicles, people, or animals from carrying the pathogen to new premises or from bringing it in from contaminated areas.

Notifying the media, while important for risk communication and public information, is not a direct biosecurity measure. It doesn’t reduce transmission at the farm or prevent spread, and such communications are best handled through official channels to avoid misinformation or operational disruption.
