AAALAC Accreditation

^ Top

        The Association for Assessment and Accreditation for Laboratory Animal Care (AAALAC) International is a private, non-profit organization that promotes the humane treatment of animals in science through voluntary accreditation and assessment programs. You can find more information here.

        CRI's Laboratory Animal Unit has been accredited by AAALAC since 2010. This involves a site visit by international experts in animal care and use for research and thorough review of the facilities and animal use program, providing a level of assurance that the animal care and use program meets the internationally-accepted reference standard. Accreditation also involves an annual report submitted to AAALAC related to any protocol violations;

        animal use not approved by the IACUC; protocol suspensions; changes in facility size, location, or name; changes in IACUC composition or members; and other changes in the animal care and use program.

        CRI’s Institute Animal Care and Use Committee (IACUC) is the oversight body for monitoring and enforcing all animal care and use activities in accordance with CRI’s ACUP, policies and standard operating procedures, as well as according to the Guide for the Care and Use of Laboratory Animals and the Ethical Principles and Guidelines for the Use of Animals for Scientific Purposes. The committee comprises CRI animal researchers, non-laboratory animal researchers, non-scientists, non-affiliated scientists, and non-affiliated non-scientists. The IACUC also conducts annual ACUP reviews and animal facility inspections, as well as reviews all CRI animal use protocols and makes recommendations for their approval to the Institutional Official (IO) prior to work on any project dealing with laboratory animals being carried out in the facility.

Animal use protocols are reviewed for:
  • Rationale and purpose of the proposed use of animals
  • A clear and concise sequential description of the procedures involving the use of animals that is easily understood
  • Availability or appropriateness of the use of less invasive procedures, alternative species, isolated organ preparation, cell or tissue culture, or computer simulation
  • Justification of the species and number of animals proposed
  • Unnecessary duplication of experiments
  • Non-standard housing and husbandry requirements
  • Impact of the proposed procedures on the animals’ well-being
  • Appropriate sedation, analgesia, and anesthesia
  • Conduct of surgical procedures, including multiple operative procedures
  • Post-procedural care and observation (e.g., inclusion of post-treatment or post-surgical animal assessment forms)
  • Description and rationale for anticipated or selected endpoints
  • Criteria and process for timely intervention, removal of animals from a study, or euthanasia if painful or stressful outcomes are anticipated
  • Method of euthanasia or disposition of animals, including planning for care of long-lived species after study completion
  • Adequacy of training and experience of personnel in the procedures used, and roles and responsibilities of the personnel involved, and
  • Use of hazardous materials and provision of a safe working environment
