Institutional and IACUC responsibilities for animal care and use education and training programs

Training and instruction of personnel are important components of animal care and use programs because they help to ensure the health and welfare of the animals and the integrity of the research or testing results. Training also helps to promote the consideration of alternatives, recognition of animal pain and distress, appropriate use of pain-relieving agents, aseptic technique, pre- and post-procedural care, and personnel health and safety. While individuals who provide the care for or conduct research or testing in laboratory animals should take personal responsibility for ensuring that they have the skills to perform their duties, the institution is ultimately responsible for ensuring their competency. The institution is also responsible for providing the training or instruction that is required by federal legislation, regulations, and policies. The institutional animal care and use committee (IACUC) is responsible for ensuring, as part of their review of research activities, that the personnel are capable of performing the procedures described. The IACUC must also assess the institution's training program as part of their semiannual animal care and use program review and make recommendations regarding training to the institutional official. This article provides a comprehensive overview of the US regulatory mandates for training and personnel qualification.     

Assessing the impact of ancient Maya animal use

Tropical forest animals are at high risk worldwide as a result of over-exploitation and forest clearing. Zooarchaeological studies of animal use by the ancient Maya of the southern lowland regions of Guatemala, Honduras, Belize, and Mexico provide long-term historical information on animal populations under conditions of human population growth and climatic change that is valuable to both archaeology and conservation biology. In this paper, zooarchaeological data from 35 chronologically defined faunal sub-samples recovered from 25 ancient Maya archaeological sites are used to assess the effects of ancient hunting on animal populations of the Maya region between the Preclassic and Colonial periods (2000 BC–AD 1697). The variations in species abundance are used as a proxy for describing changes in ancient Maya hunting practices and hunted animal populations, interpreted on the basis of hunting efficiency models from foraging ecology. A significant reduction in the proportion of large mammals, particularly Odocoileus virginianus, in zooarchaeological assemblages between the Late Classic (AD 600–850) and Terminal Classic/Postclassic periods (AD 850–1519) suggest that over-hunting during the Late Classic may have led to a reduction in availability of these animals to the ancient Maya hunters in the later periods. This finding is discussed in relation to important social and environmental variations to evaluate the impact of hunting and other factors such as forest clearance and climate on ancient animal populations in the Maya region.     

A guide to risk assessment in animal care and use programs: the metaphor of the 3-legged stool

A high-quality contemporary animal care and use program (ACUP) is a multifaceted dynamic system with three distinct organizational entities--the institutional official (IO), attending veterinarian (AV), and institutional animal care and use committee (IACUC)--each of whose authorities and responsibilities are mandated by a complex set of laws, regulations, policies, and guidelines. The 3-legged stool is presented here as a metaphor for the properly constituted and functioning ACUP, with the legs of the stool representing the IO, AV, and IACUC: when one component is weakened, the stool remains standing but tilts--the ACUP remains in compliance with animal welfare standards but is at risk of failure. Mechanisms for assessing an ACUP's strengths and weaknesses include both external evaluators, such as the US Department of Agriculture, Office of Laboratory Animal Welfare, and Association for Assessment and Accreditation of Laboratory Animal Care, and internal evaluators, such as the IACUC, AV, and IO. However, each of these evaluators primarily assesses whether aspects of the ACUP are in compliance with current standards; they do not necessarily cite weaknesses in a compliant program. This article stresses the need for ACUPs to undertake a self-assessment of risk and outlines a number of ways programs can recognize their risks, with examples for each of the three components, which are characterized as either "weak" or "overzealous" in meeting their mandates. I caution against the use of a legacy of compliance as the sole means for evaluating an ACUP's strength, and instead promote the value of rigorous risk assessment/mitigation to ensure that a program is both strong and resilient.     

Fish research and the institutional animal care and use committee

Fish represent the most diverse group of animals in the vertebrate phylum. The more than 25,000 species are characterized by an array of anatomical, biochemical, physiological, and behavioral repertoires. For this reason, it is difficult to develop a comprehensive guideline on the care and use of fishes. Institutional animal care and use committees (IACUCs) meet the challenge of ensuring adequate fish welfare using guidelines (Animal Welfare Act [AWA] and Public Health Service [PHS] Policy and their guides) derived mainly from the care and use of mammalian species, which may not be optimal for regulating fish research, teaching, or extension activities. Discussion focuses on various issues that often confront IACUCs in meeting regulatory requirements while assuring proper fish welfare. Issues include questions concerning animal tracking and inventory, utilization of fisheries bycatch, facility inspections in remote locations, and euthanasia. Common sense solutions appropriate for field and laboratory fish activities are suggested, which should help investigators, IACUCs, and regulatory agencies meet PHS and AWA objectives.     

Chemical safety in animal care,use, and research

Chemical safety is an essential element of an effective occupational health and safety program. Controlling exposures to chemical agents requires a careful process of hazard recognition, risk assessment, development of control measures, communication of the risks and control measures, and training to ensure that the indicated controls will be utilized. Managing chemical safety in animal care and use presents a unique challenge, in part because research is frequently conducted in two very different environments--the research laboratory and the animal care facility. The chemical agents specific to each of these environments are typically well understood by the employees working there; however, the extent of understanding may not be adequate when these individuals, or chemicals, cross over into the other environment. In addition, many chemicals utilized in animal research are not typically used in the research laboratory, and therefore the level of employee knowledge and proficiency may be less compared with more routinely used materials. Finally, the research protocol may involve the exposure of laboratory animals to either toxic chemicals or chemicals with unknown hazards. Such animal protocols require careful review to minimize the potential for unanticipated exposures of the research staff or animal care personnel. Numerous guidelines and regulations are cited, which define the standard of practice for the safe use of chemicals. Key chemical safety issues relevant to personnel involved in the care and use of research animals are discussed.     

A tool for semiannual review of the institutional animal care and use program

To ensure compliance with animal welfare laws and regulations, many research institutions review their animal care and use programs on a semiannual basis. In many cases, however, review committees fail to make the most of this process, basing their evaluations on general and sometimes outdated guidelines that do not address their specific needs. The authors present a worksheet that they developed and successfully implemented at their institution, aimed at inspiring an efficient and fruitful discussion of animal care and use.     

Agricultural (nonbiomedical) animal research outside the laboratory: a review of guidelines for institutional animal care and use committees

Challenges and published guidelines associated with appropriate care and use of farm animals in agricultural research conducted outside the laboratory are briefly reviewed. The Animal Welfare Act (Title 9 of the 2000 Code of Federal Regulations), which regulates the care and use of agricultural animals in biomedical research, does not include livestock and poultry used in agricultural research. Farm animal research funded (and thereby regulated) by the US Public Health Service is further discussed in the National Research Council's 1996 Guide for the Care and Use of Laboratory Animals. However, neither of these guidelines adequately addresses the unique attributes of research and teaching designed to improve production agriculture. That information is contained in the Guide for the Care and Use of Agricultural Animals in Agricultural Research and Teaching (the Ag Guide), published by the Federation of Animal Science Societies in 1999. The Ag Guide provides excellent general recommendations for agricultural animal research. It serves as an invaluable resource for institutional animal care and use committees, which attempt to balance the welfare of farm animals and the needs of those working to improve animal agriculture.     

Diagnostic molecular microbiology in laboratory animal health monitoring and surveillance programs

Molecular microbiology provides a rapid, reliable, sensitive, and specific means of detecting pathogens in laboratory animals. The author discusses the interpretation of the results of molecular microbiological testing done in conjunction with serologic, bacteriologic, and histopathologic tests, focusing on molecular microbiology as it fits in an overall program of animal health diagnostic profiling.
