USDA Inspection Report – May 2023

Texas Biomedical Research Institute and the Southwest National Primate Research Center (SNPRC) recently completed its regular, annual inspection by the United States Department of Agriculture (USDA), in which USDA veterinary inspectors review all areas of animal care and treatment. The USDA reports comprise information on activities requiring corrective action.

Texas Biomedical Research Institute has a long-standing commitment to treating its animals humanely and with the highest regard for their well-being. Unforeseen events do rarely occur, and immediate and appropriate action is taken to ensure the ongoing safety of our animals. All such events are also reported to the Office of Lab Animal Welfare and the USDA, per protocol.

The May 2023 USDA inspection report includes a count of all species at the time of inspection and one critical finding, which was reported and addressed prior to the inspection.


During an incident in early 2023, while shifting animals from one area of the caging to another for cleaning, an animal was startled, causing a care staff member to lose grip of the chute door. The door fell on the animal’s hand, prompting immediate veterinary attention. The animal underwent surgery, recovered well and is in good health following the incident.

To prevent any future occurrence, employees immediately implemented changes to the shifting procedures, including development of a pulley and locking system for chute doors and utilizing additional staff, as needed. These actions create a redundancy ensuring cages do not fall after being lifted. An internal review by the Institutional Animal Care and Use Committee found that, while procedures were followed, the implemented changes make the process safer for both employees and the animals. Standard operating protocols for shifting animals were updated to include these changes.

The USDA found the response appropriate and noted corrective action had been taken by the time of inspection.

Commitment to Care

The Institute closely monitors and continuously seeks to enhance care provided to the primates, for the sake of the animals and the quality of the research programs.

“Any time an issue arises that impacts the safety and well-being of the animals in our care, we focus on identifying and implementing the appropriate corrective action, even before USDA notes these issues,” said Dr. Corinna Ross, Director of the Southwest National Primate Research Center. “USDA indicated our corrective action was appropriate. Our responsibility to excellent care is first and foremost, as these animals enable scientists worldwide to conduct research studies that benefit both animal and human health.”
