A monkey lost a limb. The lab stayed open. The USDA hasn't imposed a single financial penalty.

A wide-eyed baby monkey peers through the green bars of a cage, clutching the bars with both small hands.

The Animal Welfare Act has been federal law since 1966. It sets minimum standards for the care of animals in research facilities and gives the USDA authority to investigate violations, issue citations, and impose financial penalties. At the University of Wisconsin-Madison Wisconsin National Primate Research Center, that authority has gone largely unused—despite years of documented, repeated violations.

What Inspectors Found

Federal inspection reports reveal a pattern of deficiencies at the facility spanning multiple inspection cycles.1,2 Citations cover animal care practices, veterinary oversight, and staff protocols. The fact that similar categories appear across multiple rounds of inspection indicates that earlier citations did not produce lasting change.

The consequences are not administrative abstractions. In one of the most severe incidents on record at this facility, a monkey lost a limb due to failures in staff care protocols.3 The amputation was a direct result of systemic lapses—not a freak accident. PETA filed a formal complaint with the USDA calling for a federal investigation,3 and local media reported on the push for a formal inquiry.5 The facility continued to operate.

A Pattern That Extends Far Beyond One Lab

The UW-Madison primate center is not an outlier in a well-functioning system. It is a visible example of a widespread problem. A report from the National Anti-Vivisection Society found that Animal Welfare Act violations at U.S. research laboratories are common, and that enforcement actions rarely reflect the scale or frequency of what inspectors actually document.6 Financial penalties, when issued at all, tend to be too small to deter large, well-funded institutions from repeating the same conduct.

An independent audit reviewed by Faunalytics reached parallel conclusions: animals in U.S. research facilities routinely experience suffering that the current inspection and penalty structure is not built to prevent.7 The gap between what the law requires and what facilities actually face when they fall short allows repeat violations to accumulate without meaningful institutional disruption.

The Authority to Act Already Exists

USDA's Animal and Plant Health Inspection Service is not limited to issuing citations. Under the Animal Welfare Act, APHIS can initiate formal enforcement proceedings and impose civil penalties scaled to the severity and repetition of violations.4 That escalation pathway was created precisely for situations like this one—years of federal findings, recurring deficiency categories, and no evidence that the current approach is working.

The animals held at this facility cannot file complaints. They cannot contact regulators. They depend entirely on the systems established to protect them. When those systems stop at citation and never reach real consequence, the law's minimum standards become a floor that facilities can fall through repeatedly.

The UW-Madison Wisconsin National Primate Research Center has had time to correct course. The record shows it has not. APHIS has the legal authority to act—it has simply chosen not to use it.

Sign the petition to tell the USDA APHIS Administrator to initiate formal enforcement action and impose financial penalties against the UW-Madison Wisconsin National Primate Research Center for its documented, repeated Animal Welfare Act violations.

The Petition

To the Administrator, Animal and Plant Health Inspection Service, United States Department of Agriculture,

The University of Wisconsin-Madison Wisconsin National Primate Research Center has accumulated documented Animal Welfare Act violations across multiple federal inspection cycles. Inspection reports reviewed by Wisconsin Public Radio and Urban Milwaukee reveal recurring deficiencies in animal care, veterinary oversight, and staff protocols—patterns that indicate earlier citations produced no lasting corrective change. We are writing to urge you to act.

The human cost of inaction is easy to overlook. The cost to animals is not. In one of the most severe incidents on record at this facility, a monkey lost a limb as a direct result of failures in care protocols. PETA filed a formal complaint with the USDA seeking a federal investigation, and local news outlets reported on the request. This was not a freak accident. It was the consequence of systemic lapses that went unaddressed through prior inspections.

The problem extends beyond this single facility. The National Anti-Vivisection Society has documented that Animal Welfare Act violations at U.S. research laboratories are widespread, and that enforcement actions rarely reflect the frequency or severity of what inspectors find. Financial penalties, when they occur, are typically too small to change behavior at large, well-resourced institutions. An audit reviewed by Faunalytics reached parallel conclusions: animals in U.S. labs routinely suffer in ways that current inspection and penalty structures are not built to prevent.

The law already gives APHIS the authority to act differently. Beyond issuing citations, the agency can initiate formal enforcement proceedings and impose civil penalties calibrated to the seriousness and repetition of violations. That escalation pathway exists for exactly the situation present at UW-Madison's primate center—years of federal findings, recurring deficiency categories, and no evidence that the current approach is producing compliance.

The animals held at this facility cannot advocate for themselves. They depend entirely on the regulatory systems established to protect them. When those systems stop at citation and never reach consequence, the law's minimum standards become a floor that facilities can fall through repeatedly without meaningful interruption to their operations.

We are asking you to initiate formal enforcement action and impose financial penalties against the UW-Madison Wisconsin National Primate Research Center commensurate with its documented, repeated violations. Exercising this authority fully and transparently will ensure a better future for all.

Sincerely,
