During vesicular disease outbreak investigation, which action is NOT an important biosecurity measure?

• A. Clean/disinfect equipment
• B. Notify media
• C. Use PPE
• D. Maintain no movement on or off farm

Answer: (B)

Notifying media is not a biosecurity measure. Biosecurity during a vesicular disease outbreak focuses on actions that directly reduce transmission of the virus. Cleaning and disinfecting equipment removes contamination that could be carried to other animals. Using appropriate PPE protects people and prevents mechanical spread of pathogens. Maintaining no movement on or off the farm stops vehicles, people, and animals from introducing or spreading infection between premises. Communicating with media doesn’t change disease spread and can create confusion or unsafe behaviors; information should be controlled through official channels to support containment efforts. Immediate reporting to veterinary authorities is essential, but it’s part of the outbreak response, not a on-farm biosecurity procedure.
