ALAT Ethics in Animal Research 2 — Questions and Answers
Question 1: Who first formally proposed the Three Rs framework for ethical animal use?
- Peter Singer in 1975
- William Russell and Rex Burch in 1959 (Correct answer)
- Jeremy Bentham in 1789
- Jane Goodall in 1986
Correct answer: William Russell and Rex Burch in 1959
Russell and Burch introduced the Three Rs in their 1959 book 'The Principles of Humane Experimental Technique.'
Russell and Burch's framework — Replacement, Reduction, and Refinement — was initially overlooked but gained prominence in the 1980s-90s. Today the Three Rs are incorporated into virtually all animal research regulations worldwide.
Question 2: What is Reduction in the context of the Three Rs?
- Reducing animal housing size
- Using methods that minimize the number of animals needed for reliable results (Correct answer)
- Reducing the budget
- Reducing the number of researchers
Correct answer: Using methods that minimize the number of animals needed for reliable results
Reduction means using statistical and experimental design methods to minimize animal numbers while achieving scientifically valid results.
Strategies include statistical power analysis, proper experimental design, pilot studies, sharing animals/tissues between investigators, and using genetically uniform strains to reduce variability.
Question 3: What ethical principle requires that animal pain be minimized unless scientifically justified?
- Informed consent
- Minimizing harm (Refinement) (Correct answer)
- Double-blind methodology
- Supply and demand
Correct answer: Minimizing harm (Refinement)
The principle of minimizing harm, embodied in Refinement, requires that pain and distress be minimized. Unalleviated pain requires specific justification.
The AWA, PHS Policy, and Guide all mandate pain minimization through appropriate anesthesia, analgesia, humane endpoints, skilled technique, and proper training. Category E use requires strong scientific justification.
Question 4: What is the ethical basis for requiring alternatives searches before approving protocols?
- To reduce costs
- To ensure non-animal methods are used when they can replace, reduce, or refine animal use (Correct answer)
- To delay projects
- To promote competition
Correct answer: To ensure non-animal methods are used when they can replace, reduce, or refine animal use
Alternatives searches ensure investigators have considered whether non-animal methods could replace animals or procedures could minimize pain.
The AWA requires written narrative describing methods and databases searched (PubMed, ALTBIB, AWIC). The search must address all Three Rs: replacement, reduction, and refinement alternatives.
Question 5: What ethical responsibility do animal care technicians have regarding welfare concerns?
- No responsibility
- An ethical and legal obligation to report through proper channels with retaliation protection (Correct answer)
- Responsibility only if they caused the problem
- Obligation to report only to direct supervisor
Correct answer: An ethical and legal obligation to report through proper channels with retaliation protection
Technicians have both ethical and legal obligations to report welfare concerns. Federal regulations provide whistleblower protections.
The AWA prohibits retaliation against good-faith reporters. Multiple avenues exist: supervisor, veterinarian, IACUC, compliance hotline, USDA-APHIS, or OLAW. Reports can be anonymous.
Question 6: What is Replacement as applied to the Three Rs?
- Replacing old equipment
- Substituting non-animal methods or lower species when scientific objectives can still be met (Correct answer)
- Replacing one research team with another
- Replacing animals that die during study
Correct answer: Substituting non-animal methods or lower species when scientific objectives can still be met
Replacement refers to using non-animal methods (in vitro, computer models) or lower phylogenetic species instead of traditional laboratory animals.
Replacement encompasses absolute replacement (cell cultures, organ-on-chip, computer modeling) and relative replacement (invertebrates, early-stage embryos). Regulatory agencies increasingly accept non-animal test methods.
