A Belmont Report For Animals?, Hope Ferdowsian, L. Syd M. Johnson, Jane Johnson, Andrew Fenton, Adam Shriver, John Gluck

John P. Gluck, PhD

Human and animal research both operate within established standards. In the United States, criticism of the human research environment and recorded abuses of human research subjects served as the impetus for the establishment of the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research, and the resulting Belmont Report. The Belmont Report established key ethical principles to which human research should adhere: respect for autonomy, obligations to beneficence and justice, and special protections for vulnerable individuals and populations. While current guidelines appropriately aim to protect the individual interests of human participants in research, no similar, comprehensive, …

Incorporating New Technologies Into Toxicity Testing And Risk Assessment: Moving From 21st Century Vision To A Data-Driven Framework, Russell S. Thomas, Martin A. Philbert, Scott Auerbach, Barbara A. Wetmore, Michael J. Devito, Ila Cote, J. Craig Rowlands, Maurice Whelan, Sean M. Hays, Melvin E. Andersen, M.E. (Bette) Meek, Lawrence W. Reiter, Jason C. Lambert, Harvey J. Clewell Iii, Martin L. Stephens, Q. Jay Zhao, Scott C. Wesselkamper, Lynn Flowers, Edward W. Carney, Tim P. Pastoor, Dan D. Petersen, Carole L. Yauk, Andy Nong

Martin Stephens, PhD

Based on existing data and previous work, a series of studies is proposed as a basis toward a pragmatic early step in transforming toxicity testing. These studies were assembled into a data-driven framework that invokes successive tiers of testing with margin of exposure (MOE) as the primary metric. The first tier of the framework integrates data from high-throughput in vitro assays, in vitro-to-in vivo extrapolation (IVIVE) pharmacokinetic modeling, and exposure modeling. The in vitro assays are used to separate chemicals based on their relative selectivity in interacting with biological targets and identify the concentration at which these interactions …

Beyond The 3rs: Expanding The Use Of Human-Relevant Replacement Methods In Biomedical Research, Kathrin Herrmann, Francesca Pistollato, Martin L. Stephens

Martin Stephens, PhD

This year marks the 60th anniversary of Russell and Burch’s pioneering book, The Principles of Humane Experimental Technique. Their 3Rs framework has helped to inspire humane and scientific progress in experimental technique. However, it is time to update its strategic application. The 21st century has already seen the development of promising, high-tech non-animal models, such as organs-on-a-chip and computational approaches that, in our view, will replace animals as the default option in biomedical experimentation. How fast this transition will take place will depend on the pace at which these new models are optimized to reflect the biology of humans, rather …

Accelerating The Development Of 21st-Century Toxicology: Outcome Of A Human Toxicology Project Consortium Workshop, Martin L. Stephens, Craig Barrow, Melvin E. Andersen, Kim Boekelheide, Paul L. Carmichael, Michael P. Holsapple, Mark Lafranconi

Martin Stephens, PhD

The U.S. National Research Council (NRC) report on “Toxicity Testing in the 21st century” calls for a fundamental shift in the way that chemicals are tested for human health effects and evaluated in risk assessments. The new approach would move toward in vitro methods, typically using human cells in a high-throughput context. The in vitro methods would be designed to detect significant perturbations to “toxicity pathways,” i.e., key biological pathways that, when sufficiently perturbed, lead to adverse health outcomes. To explore progress on the report’s implementation, the Human Toxicology Project Consortium hosted a workshop on 9–10 November 2010 in Washington, …

Welfare Challenges Influence The Complexity Of Movement: Fractal Analysis Of Behaviour In Zebrafish, Anthony G. Deakin, Joseph W. Spencer, Andrew R. Cossins, Iain S. Young, Lynne U. Sneddon

Lynne Sneddon, PhD

The ability to assess welfare is an important refinement that will ensure the good condition of animals used in experimentation. The present study investigated the impact of invasive procedures on the patterns of movement of zebrafish (Danio rerio). Recordings were made before and after fin clipping, PIT tagging and a standard pain test and these were compared with control and sham handled zebrafish. The fractal dimension (FD) from the 3D trajectories was calculated to determine the effect of these treatments on the complexity of movement patterns. While the FD of zebrafish trajectories did not differ over time in either the …

Considering Aspects Of The 3rs Principles Within Experimental Animal Biology, Lynne U. Sneddon, Lewis G. Halsey, Nic R. Bury

Lynne Sneddon, PhD

The 3Rs – Replacement, Reduction and Refinement – are embedded into the legislation and guidelines governing the ethics of animal use in experiments. Here, we consider the advantages of adopting key aspects of the 3Rs into experimental biology, represented mainly by the fields of animal behaviour, neurobiology, physiology, toxicology and biomechanics. Replacing protected animals with less sentient forms or species, cells, tissues or computer modelling approaches has been broadly successful. However, many studies investigate specific models that exhibit a particular adaptation, or a species that is a target for conservation, such that their replacement is inappropriate. Regardless of the species …

Does Environmental Enrichment Promote Recovery From Stress In Rainbow Trout?, Kieran C. Pounder, Jennifer L. Mitchell, Jack S. Thomson, Tom G. Pottinger, Jonathan Buckley, Lynne U. Sneddon

Lynne Sneddon, PhD

The EU Directive on animal experimentation suggests that all protected animals should have enrichment to improve welfare yet relatively little research has been conducted on the impact of enrichment in fish. Studies employing enrichment in zebrafish have been contradictory and all fish species should be provided with species-specific enrichments relevant to their ecology. Salmonids are important experimental models in studies within aquaculture, toxicology and natural ecosystems. This study therefore sought to establish whether an enriched environment in an experimental aquarium may promote improved welfare in rainbow trout (Oncorhynchus mykiss) by enhancing their recovery from invasive procedures. Trout were …

The Animal Research Controversy: Protest, Process & Public Policy, Andrew N. Rowan, Franklin M. Loew, Joan C. Weer

Andrew N. Rowan, DPhil

The controversy today regarding the use of animals in research appears on the surface to be a strongly polarized struggle between the scientific community and the animal protection movement. However, there is a wide range of opinions and philosophies on both sides. Mistrust between the factions has blossomed while communication has withered. Through the 1960s, 1970s and early 1980s, the animal movement grew in numbers and financial resources, and developed much greater public recognition and political clout. The research community paid relatively little attention to the animal movement for much of this period but, alarmed by several public relations coups …

International Consensus Principles For Ethical Wildlife Control, Sara Dubois, Nicole Fenwick, Erin A. Ryan, Liv Baker, Sandra E. Baker, Ngaio J.

Mellor, Daniel Ramp, Catherine A. Schuppli, David Fraser

David Fraser, PhD

Human–wildlife conflicts are commonly addressed by excluding, relocating, or lethally controlling animals with the goal of preserving public health and safety, protecting property, or conserving other valued wildlife. However, declining wildlife populations, a lack of efficacy of control methods in achieving desired outcomes, and changes in how people value animals have triggered widespread acknowledgment of the need for ethical and evidence-based approaches to managing such conflicts. We explored international perspectives on and experiences with human–wildlife conflicts to develop principles for ethical wildlife control. A diverse panel of 20 experts convened at a 2-day workshop and developed the principles through a …

Mental Stress From Animal Experiments: A Survey With Korean Researchers, Minji Kang, Ahram Han, Da-Eun Kim, Troy Seidle, Kyung-Min Lim, Seungjin Bae

Troy Seidle, PhD

Animal experiments have been widely conducted in the life sciences for more than a century, and have long been a subject of ethical and societal controversy due to the deliberate infliction of harm upon sentient animals. However, the harmful use of animals may also negatively impact the mental health of researchers themselves. We sought to evaluate the anxiety level of researchers engaged in animal use to analyse the mental stress from animal testing. The State Anxiety Scale of the State-Trait Anxiety Inventory (STAI) was used to evaluate how researchers feel when they conduct animal, as opposed to non-animal, based experiments …

Non-Invasive Methods Of Identifying And Tracking Wild Squid, Ruth A. Byrne, James B. Wood, Roland C. Anderson, Ulrike Griebel, Jennifer A. Mather

Jennifer Mather, PhD

The ability to identify individual free-living animals in the field is an important method for studying their behavior. Apart from invasive external or internal tags, which may cause injury or abnormal behavior, most cephalopods cannot be tagged, as their skin is too soft and delicate for tag retention. Additionally, cephalopods remove many types of tags. However, body markings have been successfully used as a non invasive method to identify individuals of many different species of animals, including whale sharks, grey whales, seals, and zebras. We developed methods to sex and individually identify Caribbean reef squid, Sepiotheuthis sepioidea. Males showed distinct …

Acute Toxicity Testing Without Animals: More Scientific And Less Of A Gamble, Gillian R. Langley

Gill Langley, PhD

In this report, we argue specifically that acute toxicity data should not be sought from animal tests. The underlying principle of such tests on rats and mice is that the results can be effectively extrapolated to humans. In fact, after nearly 80 years of use of these tests, the predictivity of rodent data for human acute toxic effects has been disputed but never proven.

Publication Reform To Safeguard Wildlife From Researcher Harm, Kate A. Field, Paul C. Paquet, Kyle A. Artelle, Gilbert Proulx, Ryan K. Brook, Chris T. Darimont

Chris Darimont, PhD

Despite abundant focus on responsible care of laboratory animals, we argue that inattention to the maltreatment of wildlife constitutes an ethical blind spot in contemporary animal research. We begin by reviewing significant shortcomings in legal and institutional oversight, arguing for the relatively rapid and transformational potential of editorial oversight at journals in preventing harm to vertebrates studied in the field and outside the direct supervision of institutions. Straightforward changes to animal care policies in journals, which our analysis of 206 journals suggests are either absent (34%), weak, incoherent, or neglected by researchers, could provide a practical, effective, and rapidly imposed …

Importance Of Welfare And Ethics Competence Regarding Animals Kept For Scientific Purposes To Veterinary Students In Australia And New Zealand, Teresa Collins, Amelia Cornish, Jennifer Hood, Chris Degeling, Andrew D. Fisher, Rafael Freire, Susan J. Hazel, Jane Johnson, Jennifer K.F. Lloyd, Clive J.C. Phillips, Vicky Tzioumis, Paul D. Mcgreevy

Paul McGreevy, PhD

Veterinarians are in a strong position of social influence on animal-related issues. Hence, veterinary schools have an opportunity to raise animal health and welfare standards by improving veterinary students’ animal welfare and ethics (AWE) education, including that related to animals used for scientific purposes. A survey of 818 students in the early, mid, and senior stages of their courses at all eight veterinary schools across Australia and New Zealand was undertaken on their first day of practice (or Day One Competences) to explore how veterinary students viewed the importance of their competence in the management of welfare and ethical decision-making …

Ethical And Scientific Pitfalls Concerning Laboratory Research With Non-Human Primates, And Possible Solutions, Constança Carvalho, Augusta Gaspar, Andrew Knight, Luís Vicente

Andrew Knight, PhD

Basic and applied laboratory research, whenever intrusive or invasive, presents substantial ethical challenges for ethical committees, be it with human beings or with non-human animals. In this paper we discuss the use of non-human primates (NHPs), mostly as animal models, in laboratory based research. We examine the two ethical frameworks that support current legislation and guidelines: deontology and utilitarianism. While human based research is regulated under deontological principles, guidelines for laboratory animal research rely on utilitarianism. We argue that the utilitarian framework is inadequate for this purpose: on the one hand, it is almost impossible to accurately predict the benefits …

Bias During The Evaluation Of Animal Studies, Andrew Knight

Andrew Knight, Ph.D.

My recent book entitled The Costs and Benefits of Animal Experiments seeks to answer a key question within animal ethics, namely: is animal experimentation ethically justifiable? Or, more precisely, is it justifiable within the utilitarian cost:benefit framework that fundamentally underpins most regulations governing animal experimentation? To answer this question I reviewed more than 500 scientific publications describing animal studies, animal welfare impacts, and alternative research, toxicity testing and educational methodologies. To minimise bias I focused primarily on large-scale systematic reviews that had examined the human clinical and toxicological utility of animal studies. Despite this, Dr. Susanne Prankel recently reviewed my …

Conscientious Objection To Harmful Animal Use Within Veterinary And Other Biomedical Education, Andrew Knight

Andrew Knight, PhD

Laboratory classes in which animals are seriously harmed or killed, or which use cadavers or body parts from ethically debatable sources, are controversial within veterinary and other biomedical curricula. Along with the development of more humane teaching methods, this has increasingly led to objections to participation in harmful animal use. Such cases raise a host of issues of importance to universities, including those pertaining to curricular design and course accreditation, and compliance with applicable animal welfare and antidiscrimination legislation. Accordingly, after detailed investigation, some universities have implemented formal policies to guide faculty responses to such cases, and to ensure that …

Guantánamo Bodies: Law, Media, And Biopower, Cary Federman, Dave Holmes

Cary Federman

The idea of the Guantánamo detainee as a Muselmann, the lowest order of concentration camp inmates, contains within it important implications for the new understanding of sovereignty in the era of Guantánamo, in an age of exception. The purpose of this article is to explain the status of those who are detained at Guantánamo Bay. Stated broadly, in assessing that status, we will emphasize the connection between the altered meaning of sovereignty that has accompanied the placing of prisoners in an American penal colony in Cuba and the biopolitical status of the prisoners who reside there. More particularly, we …

Critical Evaluation Of The Use Of Dogs In Biomedical Research And Testing In Europe, Nina Hasiwa, Jarrod Bailey, Peter Clausing, Mardas Daneshian, Sándor Farkas, István Gyertyán, Robert Hubrecht, Werner Kobel, Goran Krummenacher, Marcel Leist, Hannes Lohi, Adám Miklósi, Frauke Ohl, Klaus Olejniczak, Georg Schmitt, Patrick Sinnett-Smith, David Smith, Kristina Wagner, James D.

Jarrod Bailey, PhD

Dogs are sometimes referred to as “man’s best friend” and with the increase in urbanization and lifestyle changes, dogs are seen by their owners as family members. Society expresses specific concerns about the experimental use of dogs, as they are sometimes perceived to have a special status for humans. This may appear somewhat conflicting with the idea that the intrinsic value of all animals is the same, and that also several other animal species are used in biomedical research and toxicology. This aspect and many others are discussed in an introductory chapter dealing with ethical considerations on the use of …

Maintaining Ethical Standards During Conservation Crises, Ryan K. Brook, Mark Cattet, Chris T. Darimont, Paul C. Paquet, Gilbert Proulx

Chris Darimont, PhD

Many species at risk in Canada and globally are at or approaching a crisis, especially where little or nothing consequential is being done to prevent extirpation. Such is the case of endangered boreal caribou (Rangifer tarandus caribou) in southern Alberta, Canada. Expedient but inadequate emergency ‘fixes’ have been experimentally implemented to arrest their decline and potential extirpation, but use of these measures raises important ethical problems. In their study of the effects of killing wolves (Canis lupus) on the Little Smoky woodland caribou population, Hervieux et al. (2014a) employed lethal methods that included shooting a firearm from a helicopter and …

Ethical Foundations For The Lethal Management Of Double-Crested Cormorants (Phalocrocorax Auritus) In The Eastern United States: An Argument Analysis, Chelsea Batavia, Michael Paul Nelson

Chelsea Batavia, PhD

Lethal management of Double-crested Cormorants (Phalocrocorax auritus) has been implemented in many areas of the United States. In this paper, the philosophical method of argument analysis is used to assess ethical premises underlying the proposition that Double-crested Cormorant populations should be culled to reduce pressures on wild fisheries in the Great Lakes region of the eastern USA. This influential argument has been used to justify the destruction of more than half a million Double-crested Cormorants and hundreds of thousands of their nests and eggs. Three versions of the argument are formulated and assessed. It is shown that each of the …

History Of The 3rs In Toxicity Testing: From Russell And Burch To 21st Century Toxicology, Martin L. Stephens, Nina S. Mak

Martin Stephens, PhD

Toxicity testing is a key part of the process of assessing the hazards, safety, or risk that chemicals and other substances pose to humans, animals, or the environment. Standardized methods for such testing, typically involving animals, began to emerge during the first half of the 20th century. In 1959, British scientists William Russell and Rex Burch proposed a framework for reducing, refining, or replacing animal use in toxicology and other forms of biomedical experimentation. This “3Rs” or “alternatives” approach emerged at a time of growing sensitivity to the use of animals in experimentation, and progress in its implementation has been …

The Future Of Teratology Research Is In Vitro, Jarrod Bailey, Andrew Knight, Jonathan Balcombe

Jarrod Bailey, PhD

Birth defects induced by maternal exposure to exogenous agents during pregnancy are preventable, if the agents themselves can be identified and avoided. Billions of dollars and manhours have been dedicated to animal-based discovery and characterisation methods over decades. We show here, via a comprehensive systematic review and analysis of this data, that these methods constitute questionable science and pose a hazard to humans. Mean positive and negative predictivities barely exceed 50%; discordance among the species used is substantial; reliable extrapolation from animal data to humans is impossible, and virtually all known human teratogens have so far been identified in spite …

Animal Carcinogenicity Studies: 3. Alternatives To The Bioassay, Andrew Knight, Jarrod Bailey, Jonathan Balcombe

Jarrod Bailey, PhD

Conventional animal carcinogenicity tests take around three years to design, conduct and interpret. Consequently, only a tiny fraction of the thousands of industrial chemicals currently in use have been tested for carcinogenicity. Despite the costs of hundreds of millions of dollars and millions of skilled personnel hours, as well as millions of animal lives, several investigations have revealed that animal carcinogenicity data lack human specificity (i.e. the ability to identify human non-carcinogens), which severely limits the human predictivity of the bioassay. This is due to the scientific inadequacies of many carcinogenicity bioassays, and numerous serious biological obstacles, which render profoundly …

Animal Carcinogenicity Studies: 2. Obstacles To Extrapolation Of Data To Humans, Andrew Knight, Jarrod Bailey, Jonathan Balcombe

Jarrod Bailey, PhD

Due to limited human exposure data, risk classification and the consequent regulation of exposure to potential carcinogens has conventionally relied mainly upon animal tests. However, several investigations have revealed animal carcinogenicity data to be lacking in human predictivity. To investigate the reasons for this, we surveyed 160 chemicals possessing animal but not human exposure data within the US Environmental Protection Agency chemicals database, but which had received human carcinogenicity assessments by 1 January 2004. We discovered the use of a wide variety of species, with rodents predominating, and of a wide variety of routes of administration, and that there were …

Compassion As A Practical And Evolved Ethic For Conservation, David Ramp, Marc Bekoff

Marc Bekoff, PhD

The ethical position underpinning decisionmaking is an important concern for conservation biologists when setting priorities for interventions. The recent debate on how best to protect nature has centered on contrasting intrinsic and aesthetic values against utilitarian and economic values, driven by an inevitable global rise in conservation conflicts. These discussions have primarily been targeted at species and ecosystems for success, without explicitly expressing concern for the intrinsic value and welfare of individual animals. In part, this is because animal welfare has historically been thought of as an impediment to conservation. However, practical implementations of conservation that provide good welfare outcomes …

Harry F. Harlow And Animal Research: Reflection On The Ethical Paradox, John P. Gluck

John P. Gluck, PhD

With respect to the ethical debate about the treatment of animals in biomedical and behavioral research, Harry F. Harlow represents a paradox. On the one hand, his work on monkey cognition and social development fostered a view of the animals as having rich subjective lives filled with intention and emotion. On the other, he has been criticized for the conduct of research that seemed to ignore the ethical implications of his own discoveries. The basis of this contradiction is discussed and propositions for current research practice are presented.
