Footage released by the animal-rights group Peta reveals experiments at the University of Washington’s National Primate Research Center, where newborn monkeys were separated from their mothers and subjected to neurological tests after prenatal exposure to a neurotoxin. The disclosures have reignited a public debate over laboratory animal welfare and the regulatory oversight governing primate research facilities across the United States.
Macaques Show Distress During Neurotoxicity Experiments
- Maternal Separation: Infant macaques separated from mothers days after birth exhibit severe physiological and behavioral distress.
- Neurotoxicity Modeling: The experiments focused on domoic acid, a marine algae toxin, to evaluate potential impacts on learning and memory pathways.
Peta Obtains Footage of Domoic Acid Trials
The newly surfaced video recordings were obtained by Peta in September following a public records request, capturing procedures conducted between 2017 and 2019 at the Washington National Primate Research Center. Records indicate that the infant monkeys, some merely two days old, were utilized in a six-year research project examining domoic acid. This neurotoxin, produced by marine algae, accumulates in shellfish and can induce acute illness in human populations.
The footage documents young macaques with electrodes affixed to their heads, undergoing rigorous trials to ascertain whether prenatal exposure damaged their central nervous systems. The infant subjects display clear signs of distress—clutching blankets, sucking their fingers, and reacting sharply as experimenters shave their heads to test basic reflexes and memory retention. Dr. Lisa Jones-Engel, Peta’s chief science adviser on primate issues, stated that the visual evidence exposes an underlying reality of laboratory environments that institutions have historically kept out of public view.
Research Center Defends Prenatal Toxin Studies
The infant macaques were bred directly at the facility’s Infant Primate Research Laboratory. Researchers administered daily doses of domoic acid to 32 pregnant macaques.
In response to the public release of the footage, representatives for the Washington National Primate Research Center defended the work, noting that the studies contributed valuable data regarding how prenatal domoic acid exposure affects learning and memory pathways. The facility maintained that its experienced veterinary and animal care personnel possess specialized expertise in nursery rearing and asserted that animal studies remain necessary for complex scientific questions. The National Institutes of Health, which provided more than $4.2 million in funding for the project, stated that all supported research adheres strictly to federal laws designed to minimize animal usage and prioritize welfare.
Broader Infectious Disease Research and Legal Disputes
Although the specific domoic acid project concluded in 2020, records show that the primate center continued breeding and utilizing infant monkeys for other high-consequence investigations, including studies involving the Epstein-Barr virus and simian immunodeficiency virus, a pathogen closely related to HIV. In a 2021 study, 25 infant rhesus macaques were infected with SIV to examine rapid disease progression.
The release of these records compounds a history of legal conflict between Peta and the university. In a 2020 lawsuit, a King County Superior Court ruled that the university violated public records laws by failing to adequately search for requested documents and routinely destroying photos and videos related to the primate center.

UW HAS SOME EXPLAINING TO DO.PETA obtained this never-before-seen footage through a public records request, and now the public is getting a look at what @UW has done to infant monkeys 💔We didn't expose this just for people to look away 👉 https://t.co/OieffIJUwd pic.twitter.com/O0KNJjFIm0
Please share PETA’s video on social media. Then, please TAKE ACTION to help shut down the Washington National Primate Research Center 👇 https://t.co/W73NgwYpqs
