Animal Testing Regulations - United States

United States

Further information: Institutional Animal Care and Use Committee

In the United States, animal testing on vertebrates is primarily regulated by the Animal Welfare Act of 1966 (AWA), which is enforced by the Animal Care division of the Animal and Plant Health Inspection Service (APHIS) of the United States Department of Agriculture (USDA). The AWA contains provisions to ensure that individuals of covered species used in research receive a certain standard of care and treatment, provided that the standard of care and treatment does not interfere with "the design, outlines, or guidelines of actual research or experimentation." Currently, AWA only protects mammals. In 2002, the Farm Security Act of 2002, the fifth amendment to the AWA, specifically excluded purpose-bred birds, rats, and mice (as opposed to wild-captured mice, rats, and birds) from regulations. Thus, relatively few animals used in research in the U.S. are covered by this legislation. The AWA requires each institution using covered species to maintain an Institutional Animal Care and Use Committee (IACUC), which is responsible for local compliance with the Act.

Animal care and use in research in the United States are largely controlled by Institutional Animal Care and Use Committees.

Research suggests that the IACUC system is unreliable. A study conducted in 2001 by Psychology Professor Scott Plous of Wesleyan University that evaluated the reliability of IACUCs found little consistency between decisions made by IACUCs at different institutions. A Wesleyan University press release summarized part of the findings:

The investigation, which took three years to complete, compared judgments made by 50 randomly selected animal care and use committees drawn from U.S. colleges and universities. To assess the consistency of approval decisions, 150 recent research proposals from these institutions were each independently evaluated by two different animal care and use committees.
The results showed that approval decisions were statistically unrelated. In most cases, proposals that were disapproved by one committee were approved by the second committee. The study also explored whether reviews were more reliable when the experiment involved certain types of animals or procedures. For example, reliability was assessed for proposals that involved dogs, cats, and primates, or for experiments involving drugs, surgery, animal pain, or death. Even in these cases, independent reviews did not agree beyond chance levels.

In response to the Plous study, a rebuttal letter to Science written by animal researchers, animal care staff, and members of professional research societies stated:

That the masked protocols would be rated more negatively was predictable for the following reasons. First, IACUCs rely on knowing the experience of the investigators and staff, information that was not included for the unofficial IACUCs. Not surprisingly, most of the negative shifts (84 of 118) were to categories calling for more information. Second, withholding approval had no practical consequence. Third, participants might have felt scrutinized by researchers with an "animal rights" agenda, and erred on the side of deferral or rejection. Fourth, navigating another institution's forms can be difficult. And fifth, IACUCs unfamiliar with particular species or procedures are less likely to understand a protocol. These factors make it almost impossible to compare the actions of the original and unofficial IACUCs and thus call into question the major premises and conclusions of this study.

Institutions are also subject to unannounced annual inspections from USDA APHIS Veterinarian inspectors. There are about 70 inspectors monitoring around 1100 research institutions. The inspectors also conduct pre-licensing checks for sites that do not engage in animal research or transportation, of which more than 4000 exist (e.g. dog kennels).

APHIS has been criticized by its own inspectors and the USDA Inspector General's office (OIG). Marshall Smith, an APHIS inspector for twelve years, resigned in 1997 recounting a litany of problems at the agency that impeded his duties. In a prepared statement, Smith made note of a 1992 OIG report citing the agency's inability to ensure the humane care of animals at dealers. In 2000, Isis Johnson-Brown D.V.M. – another APHIS inspector – quit because of problems she documented at the Oregon National Primate Research Center, in Beaverton, Oregon. In a prepared statement Dr. Johnson said:

More than once, I was instructed by a supervisor to make a personal list of violations of the law, cut that list in half, and then cut that list in half again before writing up my inspection reports. My willingness to uphold the law during my site visits at the Primate Center led to me being 'retrained' several times by higher-ups in the USDA.

In 2005, the USDA OIG issued another report on APHIS:

Of particular concern, AC management in the Eastern Region is not aggressively pursuing enforcement actions against violators of the AWA. The Eastern Region significantly reduced its referrals of suspected violators to the Investigative and Enforcement Services (IES) unit—from an average of 209 cases in fiscal years (FYs) 2002–2003 to 82 cases in FY 2004. When the region did refer cases to IES, management declined to take enforcement action against 126 of 475 violators (27 percent).

When violators are assessed stipulated fines, the fines are usually minimal and not always effective in preventing subsequent violations. Under current APHIS policy, AC gives an automatic 75-percent discount to almost all violators as a means of amicably reaching an agreement on the amount of the fines and avoiding court.

Finally, we noted that some VMOs when inspecting research facilities do not verify the number of animals used in medical research or adequately review the facilities’ protocols and other records.

Another regulatory instrument is the Public Health Service (PHS) Policy on Humane Care and Use of Laboratory Animals, which became statutory with the Health Research Extension Act 1985, and which is enforced by the Office of Laboratory Animal Welfare (OLAW). This Act applies to any individual scientist or institution in receipt of federal funds and requires each institution to have an IACUC. OLAW enforces the standards of the Guide for the Care and Use of Laboratory Animals published by the Institute for Laboratory Animal Research, which includes all vertebrate species in its care protocols, including rodents and birds (Introduction, p. 1). In 2004, the National Institutes of Health provided funds to 3,180 different research institutions and universities. This means that IACUCs oversee the use of all vertebrate species in research at facilities receiving federal funds, even if the species are not covered by the AWA. OLAW does not carry out scheduled inspections, but requires that "As a condition of receipt of PHS support for research involving laboratory animals, awardee institutions must provide a written Animal Welfare Assurance of Compliance (Assurance) to OLAW describing the means they will employ to comply with the PHS Policy." OLAW conducts inspections only when there is a suspected or alleged violation that cannot be resolved through written correspondence. Accreditation from the Association for Assessment and Accreditation of Laboratory Animal Care International (AAALAC), a non-governmental, nonprofit association, is regarded by the industry as the "gold standard" of accreditation. Accreditation is maintained through a prearranged AAALAC site visit and program evaluation hosted by the member institution once every three years. Accreditation is intended to ensure compliance with the standards in the Guide for the Care and Use of Laboratory Animals, as well as any other national or local laws on animal welfare.

Famous quotes related to united states:

    ... it is probable that in a fit of generosity the men of the United States would have enfranchised its women en masse; and the government now staggering under the ballots of ignorant, irresponsible men, must have gone down under the additional burden of the votes which would have been thrown upon it, by millions of ignorant, irresponsible women.
    Jane Grey Swisshelm (1815–1884)

    What makes the United States government, on the whole, more tolerable—I mean for us lucky white men—is the fact that there is so much less of government with us.... But in Canada you are reminded of the government every day. It parades itself before you. It is not content to be the servant, but will be the master; and every day it goes out to the Plains of Abraham or to the Champs de Mars and exhibits itself and toots.
    Henry David Thoreau (1817–1862)

    Hollywood ... was the place where the United States perpetrated itself as a universal dream and put the dream into mass production.
    Angela Carter (1940–1992)

    The parallel between antifeminism and race prejudice is striking. The same underlying motives appear to be at work, namely fear, jealousy, feelings of insecurity, fear of economic competition, guilt feelings, and the like. Many of the leaders of the feminist movement in the nineteenth-century United States clearly understood the similarity of the motives at work in antifeminism and race discrimination and associated themselves with the anti slavery movement.
    Ashley Montagu (b. 1905)

    Fortunately, the time has long passed when people liked to regard the United States as some kind of melting pot, taking men and women from every part of the world and converting them into standardized, homogenized Americans. We are, I think, much more mature and wise today. Just as we welcome a world of diversity, so we glory in an America of diversity—an America all the richer for the many different and distinctive strands of which it is woven.
    Hubert H. Humphrey (1911–1978)
