In Hong Kong, a highly developed center for research and medicine, laboratory animals are often the unsung contributors to scientific advancement and human health. However, the welfare of these animals, who sacrifice their lives in laboratories for human benefits, has long been neglected, remaining in a blind spot of public visibility and legal regulation. The current regulatory model relies on institutional “self-regulation,” which starkly contrasts with the increasingly strict ethical standards for animal experimentation adopted by the international community. The dual lack of independence and transparency in this model represents a significant shortcoming in Hong Kong’s animal welfare policy. The research department of the Hong Kong Society for the Prevention of Cruelty to Animals emphasizes that a civilized and advanced city must not only pursue scientific excellence but also ensure that its scientific practices adhere to the highest ethical standards. Drawing from international experiences, it is imperative to create an independent, transparent, and credible local oversight framework as a social responsibility that cannot be ignored.

• Structural Defects of the Current “Institutional Self-Regulation” Model
  
  Presently, the oversight of laboratory animal welfare in Hong Kong primarily relies on the “Code of Practice for the Care and Use of Laboratory Animals” issued by the Agriculture, Fisheries, and Conservation Department. While this code provides basic guidelines, its fundamental issue lies in the lack of legal enforcement, with its enforcement mechanisms based upon “institutional self-regulation.” Specifically, the review and oversight responsibilities are almost entirely delegated to the “Animal Experimentation Ethics Committees” established within each research institution.
  
  This model presents several insurmountable structural defects. First, there is a severe lack of independence. The members of these internal committees are often composed of researchers and administrators from the institution, making it difficult to completely separate their review work from the financial pressures and scientific interests of the institution. When major or potentially controversial animal experimentation projects arise, it is challenging to ascertain whether the committee can genuinely prioritize “animal welfare.” Secondly, a lack of uniformity and a transparency black hole exists. Each institution interprets and implements the code differently, leading to a lack of standardized, comparable welfare standards throughout Hong Kong. More critically, the number, species, severity of suffering, and the specific processes and outcomes of ethical review for laboratory animals need not be disclosed to the public. This creates a closed “self-monitoring” cycle, contradicting modern societal expectations for public accountability and information transparency.
  
• The Core of International Standards: The “3Rs” Principle and Independent Oversight Framework
  
  To reform Hong Kong’s system, it is essential to grasp the internationally accepted golden standard. The “3Rs” principle—Replacement, Reduction, and Refinement— advocated by authoritative bodies like the International Council for Laboratory Animal Science, has become a cornerstone of global ethical standards for laboratory animal welfare. This principle requires researchers to prioritize non-animal alternative methods during the planning phase; use the fewest animals possible when alternatives cannot be found; and minimize potential suffering through improved techniques and care. However, the implementation of the “3Rs” cannot rely solely on researchers’ self- awareness; a robust external oversight framework is necessary to ensure compliance. In advanced regions like Europe and North America, this framework typically includes two key elements: a statutory, empowered internal ethics committee whose membership must include independent individuals (such as outside animal welfare experts and community representatives) with the authority to veto unethical experimental proposals. Additionally, national-level external monitoring and certification systems, such as the United States’ Institutional Animal Care and Use Committee system or the periodic audits and facility certification systems commonly practiced in EU countries, ensure the independence of oversight and maintain transparency through mandatory reporting and disclosure requirements.
  
• The Feasibility of Constructing a Localized Oversight Framework Based on International Experience
  
  Hong Kong is well-positioned to learn from these international best practices and establish a localized oversight framework tailored to its actual circumstances. As a law- abiding international metropolis with a dense concentration of research institutions, Hong Kong has a solid foundation for reform. The key to reform lies in converting the current soft guidelines of “self-monitoring” into a robust “independent oversight” system.
  
  This does not mean copying foreign laws verbatim but rather creatively adapting them to local contexts. For instance, the “Prevention of Cruelty to Animals Ordinance” could be amended to grant the “Code of Practice for the Care and Use of Laboratory Animals” or its core “3Rs” principle the status of subordinate legislation, making compliance with these principles a legal obligation rather than merely a moral suggestion. Additionally, legislation could mandate that all institutions using laboratory animals must include a minimum percentage of independent external members on their ethics committees, with standardized regulations governing their composition and authority.
  
  Moreover, it is crucial for Hong Kong to establish a centralized, independent external oversight agency. This agency could operate within the existing system but must ensure its independence or be formed through joint participation of credible stakeholders. Its responsibilities should include: developing unified animal welfare standards and ethical review guidelines; conducting unannounced random inspections of all research institutions; reviewing annual statistical reports; and handling and investigating relevant complaints. The agency’s annual report should be submitted to the Legislative Council and made publicly available, thereby breaking the black-box phenomenon and inviting social oversight.
  
• Specific Policy Recommendations: Moving Towards an Independent, Transparent, and Credible Regulatory Era
  
  To achieve these reforms, the research department of the Hong Kong Society for the Prevention of Cruelty to Animals proposes the following four specific policy recommendations:
  
  1. Initiate Legislative Amendments to Establish the Legal Status of the “3Rs” and a Mandatory Animal Experimental Ethics Review System.
  
  The government should promptly review the “Prevention of Cruelty to Animals Ordinance” and consider adding a dedicated chapter or creating specific regulations that explicitly incorporate the “Replacement, Reduction, and Refinement” principles and detailed ethical review processes into the law. The law should clearly state that any scientific research involving animals must be approved in advance by a properly constituted institutional ethics committee; otherwise, it will be illegal.
  
  2. Establish a Statutory Independent “Hong Kong Laboratory Animal Welfare Oversight Committee.”
  
  This committee should be empowered by law and include members such as animal welfare scientists, veterinarians, ethicists, legal experts, and public representatives. Its core authority would encompass approving and monitoring the functions of institutional ethics committees; developing citywide welfare guidelines; conducting surprise inspections and in-depth investigations; and collecting, analyzing, and publicly disclosing data on laboratory animal usage across Hong Kong.
  
  3. Implement a Mandatory Public Disclosure System for Non-Technical Project Summaries.
  
  To enhance transparency, legislation should require that all approved animal experimentation projects must provide a publicly understandable “non-technical project summary” upon commencement. This summary should outline the research purpose, justification for using animals, types and numbers of animals used, and potential harms and mitigation measures. These summaries should be uniformly published by the oversight committee, ensuring the public’s right to know and supervise.
  
  4. Enhance Mandatory Ethical Training for Researchers and Ethics Committee Members.
  
  The government should fund and regulate a comprehensive training and certification system to ensure that all researchers and ethics committee members involved in animal experimentation receive periodic training on the “3Rs,” animal welfare science, ethical analysis, and relevant regulations. This training should be a prerequisite for employment or conducting research.

Conclusion: Aligning Ethics with Scientific Progress

The contributions of laboratory animals cannot be dismissed, but the ethical responsibilities society bears toward them cannot be overlooked. A Hong Kong that strives for excellence in research should also serve as a role model for ethical practices and animal welfare protections. The current closed, self-regulatory model is inadequate to meet societal expectations. We urge the HKSAR government, the legislative body, the research community, and the general public to recognize this significant, hidden ethical issue behind laboratory doors and to decisively advocate for systemic reform. By establishing an independent, transparent regulatory framework backed by law, we can ensure that laboratory animals receive the welfare they deserve while enhancing Hong Kong’s international reputation and elevating its moral standards in scientific progress and respect for life.
