treatment of the infection. In January 2020, a juvenile macaque was trapped under a steel trough drain cover after a technical had not properly secured the cover. In August 2020, two macaques were killed when a technician accidentally put their cage, with the macaques inside, into an automatic cage washer. In October 2020, two macaques managed to escape from their cages and injured five other macaques, who were in their cages. In October 2021, two macaques were injured after the barrier between their cages malfunctioned, which allowed the macaques to access each other. The macaques fought and sustained injuries which took several days to heal. Animal care oversight The center receives unannounced bi-annual inspections by the United States Department of Agriculture. It has been accredited by the Association for Assessment and Accreditation of Laboratory Animal Care International since 1975. As required by the Animal Welfare Act, the center also maintains an Institutional Animal Care and Use Committee; each IACUC must consist of at least one veterinarian with training in laboratory animal science and expertise in the species under consideration, at least one practicing research scientist, and at least one person not affiliated with the institution to represent community interests in proper care and use of animals. Animal rights groups In 2000, animal rights activist Matt Rossell posed as a laboratory technician and later released video footage he had taken from inside the center. He accused them of violating federal laws and ignoring signs of distress among the rhesus monkeys housed there. "OHSU responded that Rossell's motives were suspect and his videotapes misleading." The USDA concluded that the allegations were unfounded. In 2007, People for the Ethical Treatment of Animals (PETA) filed a complaint with the federal government after one of their members obtained a job at the primate center for day to day animal care and was able to take video and photos. A center spokesman said the behavior of the monkeys seen in the footage was attributable to the infiltrator entering into and creating an unfamiliar environment for the animals.
