Which of the following is true regarding the use of animals in research?

The correct statement regarding the use of animals in research is that the attending veterinarian must have access to all research animals at all times. This requirement is in place to ensure the health and welfare of the animals used in research. The attending veterinarian plays a crucial role in overseeing animal care and ensuring that research protocols comply with established standards of animal welfare. By having unrestricted access to all research animals, the veterinarian can monitor their health, diagnose any issues promptly, and provide necessary medical treatment, thereby upholding ethical considerations in research.

While other options might touch on aspects of regulations and the management of animal use in research, they do not accurately reflect the necessary protocols related to veterinary oversight. For instance, the first option pertains to the transparency of IACUC meetings, which may not be broadly accessible to the public. The second option incorrectly limits veterinary oversight to only primates, overlooking other species that also require veterinary care. The third option inaccurately states that IACUC review is limited to USDA-funded research when, in fact, compliance with IACUC review is mandated for any federally funded research involving animals.
