How is biosafety integrated into animal research practices?

• A. Risk assessments, containment measures, PPE, vaccination where appropriate, sterilization, and oversight by biosafety professionals; risk-informed protocol design.
• B. Vaccination where appropriate.
• C. Documentation of staff names only.
• D. External audits every five years.

Answer: (A)

Biosafety in animal research is a systematic, layered approach to protect people, animals, and the environment. It starts with risk assessments to identify hazards and determine appropriate containment and controls. This includes using containment measures and engineered controls, proper PPE, and procedures that limit exposure during handling, dosing, sampling, and housing. Vaccination where appropriate helps reduce risk for personnel and animals when supported by evidence and guidelines. Sterilization and decontamination prevent cross-contamination and environmental release. Oversight by biosafety professionals and committees ensures that practices stay compliant, up-to-date, and aligned with risk levels, with risk-informed protocol design guiding the choice of methods, facilities, and procedures. When a range of controls is considered together, it creates a robust safety net beyond any single measure. Other options only emphasize a narrow aspect or omit oversight and design considerations, making them insufficient alone.
