Animal Care Program Openness Statement
The UC Davis animal care program is one of the largest and most diverse in the nation. We are incredibly proud of our program and take animal welfare very seriously. We understand that working with animals is a privilege and that it is our responsibility to provide exemplary care.
We are a USDA registered facility and as such conduct animal research in compliance with the regulations and standards of the Animal Welfare Act. As are all USDA registered facilities, we have annual unannounced inspections by Animal and Plant Health Inspection Service Veterinary Medical Officers who assess the animals, facilities, food and water supply, medications and records.
All research proposals are thoroughly reviewed by our Institutional Animal Care and Use committee prior to any animal studies and require approval before commencing. The membership of this committee is constituted by veterinarians, physiologists, immunologists, wildlife conservationists and at least one member whose primary concerns are in a nonscientific area (e.g., ethicist, lawyer). There is also at least one member not affiliated with the institution in order to include a diverse opinion from the surrounding community. This learned group of scientists and vested individuals provide close oversight and ensure that we follow all federal and state guidelines for the ethical use of laboratory animals in support of human health and welfare.
We believe in openness and transparency about the important work we do and are voluntarily posting our inspection reports.

1. A review of records found that four more cows had been included on a non-invasive teaching protocol than originally approved by the IACUC. The ordering system has been changed to not allow orders exceeding approved numbers. The issue had been corrected at the time of inspection.
2. In March 2024, staff found that two short-tailed opossums had escaped their enclosures overnight. One was found alive in an escape enclosure that was left in the room to allow an escaped animal to find refuge. The other animal was found deceased. A necropsy did not determine a cause of death.
Escapes of these animals are rare. They are territorial and one opossum may have kept the other out of the escape refuge.
Staff have ordered new tops for the enclosures and will place an extra escape refuge in each room.

On Dec. 3, 2023 UC Davis officials had self-reported to USDA that a juvenile rhesus macaque had been found dead after becoming entangled in a loose bungie cord used to secure a canvas canopy over an outdoor enclosure.
These canopies are attached to a metal frame with bungie cords. The elastic cords are fastened to the frame with zip ties so that they cannot fall or be pulled into the enclosure if they become loose. Most of the bungies are out of reach of the animals. In this case, one bungie at the edge of the enclosure was in reach and did become loose enough for the animal to reach through fencing, pull on it and become entangled. A necropsy found that both pre-existing heart disease and the entanglement played a role in the death.
UC Davis is in the process of replacing canvas shades with permanent canopies, with about 80 percent completed at the time of the incident. Canvas shades under permanent canopies were all removed following this accident. Where bungie cords are still in use, they have been secured with a second zip tie.
The inspector noted that the problem had been corrected at the time of inspection.
December 6, 2023 Inspection
Focused inspection.
On Sept. 13, an ewe delivered four lambs, all underweight. To encourage bonding and nursing, staff constructed a smaller enclosed area in the pen. The lambs were checked often and appeared to be nursing, but between 5:30 and 6 P.M. one of the lambs got its head and neck caught between a metal bar and wall hinge. Staff tried to resuscitate it but were unsuccessful.
UC Davis self-reported the incident to USDA and adapted the design of the pen to prevent this from happening again. USDA noted that the issue had been corrected at the time of inspection.
October 10, 2023 Inspection
Focused inspection.
- In August 2023, an adult male rhesus macaque had to be euthanized after presenting with weight loss, lethargy and diarrhea. Although daily health checks were carried out, the weight loss exceeded the campus’s humane endpoint criteria. UC Davis self-reported the incident to USDA. Veterinary officers carried out a focused inspection and issued a critical report.
- A rhesus macaque had to be euthanized after being left unattended in a van and becoming overheated. UC Davis self-reported the incident to USDA and also commissioned a review by an external expert. This report was publicly disclosed in Sept. 2023. USDA carried out a focused inspection and issued a critical report.

For three days, four cows were on a teaching protocol that had expired and was awaiting renewal. The error was discovered a month later during the renewal process and self-reported to USDA. The IACUC advised the investigator to cease all activity and transfer animals to a current holding protocol.
Inspectors reviewed the incident and noted that it had been corrected at the time of inspection.

On March 14, researchers reported to the IACUC office that according to their records, a California mouse was missing. The California mouse (Peromyscus californicus) is a rodent species native to California distinct from the “house mouse” (Mus musculus) commonly used in medical research.
The mice were being checked daily and there was a discrepancy in the count over the weekend.
Staff set live traps but the animal was not recovered. There were no signs of damage to the animal housing. UC Davis staff believe that the discrepancy was a clerical error.
The incident was self-reported to USDA. Inspectors visited the facility on March 16 and issued a critical incident report.
