Which of the following can be a consequence of the introduction of vermin into the facility?

• A. Food contamination
• B. Compromised experimental data
• C. Damage to electrical cords
• D. All of the above

Answer: (D)

Vermin in a research setting create multiple risk pathways that can affect animals, experiments, and safety. They contaminate food and surfaces with droppings, urine, and fur and can carry pathogens, which may cause illness in animals or staff and introduce uncontrolled variability that compromises experimental data. They also chew on electrical cords and insulation, creating electrical hazards, short circuits, or outages that disrupt studies and facility operations. Cages and equipment can be damaged as well. Because each of these problems can occur, all of these consequences are possible, making “all of the above” the best answer. To minimize risk, an integrated pest management approach that focuses on sanitation, exclusion, monitoring, and rapid response is essential.
