How often does USDA inspect each animal research facility?

The correct answer, which states that the USDA inspects each animal research facility annually, reflects the regulatory framework established under the Animal Welfare Act (AWA). The AWA mandates that the USDA conducts inspections to ensure that facilities comply with animal care standards necessary for the humane treatment of animals used in research, exhibition, transport, or those held by dealers.

The annual inspection schedule is designed to maintain a balance between oversight and practicality for facilities that may have various operational scales. By inspecting on this schedule, the USDA can effectively monitor adherence to regulations and ensure that animal welfare is prioritized.

Other frequencies like monthly, bi-annually, or quarterly would imply a much higher demand for oversight than what the regulations stipulate. Such frequencies may be impractical and could possibly burden facilities unless specific concerns arise that warrant more frequent inspections.
