The U.S. Department of Agriculture (USDA) today removed public access to tens of thousands of reports that document the numbers of animals kept by research labs, companies, zoos, circuses, and animal transporters—and whether those animals are being treated humanely under the Animal Welfare Act. Henceforth, those wanting access to the information will need to file a Freedom of Information Act request. The same goes for inspection reports under the Horse Protection Act, which prohibits injuring horses’ hooves or legs for show.

The agency said in a statement that it revoked public access to the reports “based on our commitment to being transparent … and maintaining the privacy rights of individuals.”

The reports apply to 7813 facilities that keep animals covered by the law. Roughly 1200 of these are research labs, which are often housed at major academic centers or run by government agencies themselves, including the National Institutes of Health, the Food and Drug Administration, and the Centers for Disease Control and Prevention. Although the act covers animals like dogs and chimpanzees, it does not cover rodents like laboratory mice.

USDA inspectors routinely visit facilities and upload inspection reports like this one to the agency website several months later. Labs, companies, and others covered by the act are also required to file annual censuses like this one cataloging the number and kinds of animals in their care.

Inspection reports contain little, if any, personal information about individuals.

Public access to the reports has led to scores of media reports like this article in The Boston Globe in 2012 documenting problems at Harvard University’s primate research facility; the university later closed the trouble-prone New England Primate Research Center. Similarly, the reports allowed Nature and The New Yorker to report on the chronic abuse of goats held at the private company Santa Cruz Biotechnology in California, once the world’s second largest marketer of research antibodies. Several months after the Nature report, USDA in a rare move revoked the company’s license to market the antibodies.

“[These are] basic data about animal use and compliance that taxpayers have a right to access, particularly when it comes to taxpayer-funded labs,” says Justin Goodman, vice president of advocacy and public policy at the White Coat Waste Project, a Washington, D.C.–based group that opposes taxpayer-funded animal experiments.

The Humane Society of the United States said in a statement: “This action benefits no one, except facilities who have harmed animals and don’t want anyone to know.”
