Guidelines for development and application of aquatic animal health regulations and control programs. AVMA Aquaculture and Seafood Advisory Committee.

The creation of sound health regulations or disease control programs for any animal species is a complex endeavor. When the diverse stakeholder interests related to aquaculture are considered, this endeavor becomes daunting. The AVMA Aquaculture and Seafood Advisory Committee designed the following guidelines as a tool to assist aquatic animal health professionals who discuss potential regulations or control programs with government and industry entities. The guide focuses on determining whether a regulation or program is appropriate and, if so, developing a suitable and effective aquatic animal health plan. The Aquaculture and Seafood Advisory Committee was established in 1992 as an ad hoc committee of the AVMA Executive Board. The committee is composed of 9 veterinarians with diverse interests in aquaculture and seafood, and one non-veterinarian who represents the aquaculture industry. Participants from the USDA/APHIS and FDA serve as consultants to the Committee.     

Progress of the comparative MHC Committee and a summary of the Comparative MHC Workshops held at the 32nd ISAG, Edinburgh and the 9th IVIS, Tokyo, 2010

The comparative MHC Nomenclature Committee was formed following a recommendation by the International Society for Animal Genetics (ISAG) at its meeting in G?ttingen, Germany in 2002. The committee subsequently became affiliated to VIC, the Veterinary Immunology Committee of IUIS; the International Union of Immunological Societies, which is the umbrella organization for immunology societies worldwide. The committee currently fulfils three roles: (1) to establish guidelines for MHC nomenclature in species outside of human and mouse, (2) to facilitate the development of databases which provide a source of validated MHC sequences with official nomenclatures for associated species (immuno-polymorphism database IPD-MHC) and (3) to facilitate scientific discussion on comparative aspects of MHC biology. The committee currently comprises individuals representing a range of species nomenclature committees. This report summarises progress the committee has made in addressing its core objectives as well as the principal outputs from the Comparative MHC Workshops held at the 32nd International Society for Animal Genetics (ISAG) conference in Edinburgh, UK in July 2010 as well as in August 2010 at the 9th International Veterinary Immunology Symposium (IVIS) in Tokyo, Japan. Additional data from posters and presentations at related workshops focussing on aspects of MHC biology are also included where appropriate.     

The Queensland Poisonous Plants Committee: its history and functions

SUMMARY The Queensland Poisonous Plants Committee was established in 1937 with Professor HR Seddon as chairman. It has functioned since that year, interrupted by two periods of inactivity in 1951–9 and 1962–8. Professor Seddon, first Dean of the Queensland Veterinary School, and Dr Selwyn Everist, Queensland Government Botanist after the Second World War, provided the main impetus for committee activities in its early and middle years, respectively. The strength of the body has been its multi-disciplinary approach using contributions from veterinarians, chemists and botanists. The research work of the committee members and their associates has provided most of our current knowledge of the toxins and effects of poisonous plants in Queensland. Much of the information generated is of international significance. In equal partnership with the United States Department of Agriculture, the committee initiated a series of international symposia on plant poisoning of animals, hosting the second. This group held its 4th gathering of world authorities in the field in 1993. The committee's activities have long influenced the veterinary profession in Australia through the close involvement of its members in undergraduate and post-graduate teaching in the Queensland Veterinary School since 1951. The present committee has members from the Departments of Primary Industries, Health, and Environment and Heritage, CSIRO and the University of Queensland.     

Health council report: "Antimicrobial growth promoters"

The Health Council of the Netherlands has issued a report on the risk of development of resistance among bacteria as result of the use of antibiotics as growth promotors in livestock farming. The committee appointed by the Health Council conclude that the use of antimicrobial growth promotors contributes to the problem of resistance among human pathogens. The conclusions are based on evidence regarding the development of resistance in livestock as the result of the use of antimicrobial growth promotors, the possibility of colonisation/infection of humans with resistant bacteria from the intestinal flora of productive livestock, and the transfer of resistance genes from livestock bacteria to human pathogenic microorganisms. Effective measures for the limitation of the public health risk should focus on termination of the use of antimicrobial growth promotors that confer resistance to (related) antibiotics currently used (or which will be available) to treat patients suffering from bacterial infections. In addition, the committee advised ending the use of antimicrobial growth promotors in 3 years.     

Veterinary development

Extract

The honour of being President gives one the opportunity of repaying the Association and the profession for the right to practise veterinary science in an environment which they have helped to create. It also gives the President the opportunity of a close association with other groups of people who are directly associated with our profession for it has been said that no man is an island and this is exceptionally so as far as the veterinary profession is concerned. While we are individuals, some more so than others, it is only as a cohesive organization that we can survive and progress. It is sometimes forgotten that the President and Council of the Association are elected by veterinarians, to make decisions on behalf of the veterinary profession. It is sometimes forgotten that the President and Council of the New Zealand Veterinary Association are veterinarians who are affected by decisions made, just as much as any colleague. To make a decision is to invite criticism; time will prove many decisions to be wrong, but there is a great satisfaction when a decision made proves to be the right one. I believe that a correct decision made is progress and this is the subject that I choose to discuss with you. I could talk about the past but that was yesterday and it is argued that there is no guidance in the past, for the problems of the future. I could talk about the future, but the future is tomorrow, so I will confine myself to the present and the problems associated with making progress in our present environment. I have said that the Veterinary Association is not an island, that its future, present and past are intricately tied to the farming endeavour of New Zealand as are many other organizations. I have had the, pleasure over the last 18 months of sitting on a ministerial committee called “The Committee of Veterinary Development”. As many will know, this committee was established at the request of the New Zealand Veterinary Association. Of major concern to us was the representations on this committee, for it consisted of administrative officers of the Department of Agriculture, Federated Farmers, the New Zealand Veterinary Association, and an independent chairman.     

Antimicrobial drug use in veterinary medicine

Recognizing the importance of antimicrobial resistance and the need for veterinarians to aid in efforts for maintaining the usefulness of antimicrobial drugs in animals and humans, the Board of Regents of the American College of Veterinary Internal Medicine charged a special committee with responsibility for drafting this position statement regarding antimicrobial drug use in veterinary medicine. The Committee believes that veterinarians are obligated to balance the well-being of animals under their care with the protection of other animals and public health. Therefore, if an animal's medical condition can be reasonably expected to improve as a result of treatment with antimicrobial drugs, and the animal is under a veterinarian's care with an appropriate veterinarian-client-patient relationship, veterinarians have an obligation to offer antimicrobial treatment as a therapeutic option. Veterinarians also have an obligation to actively promote disease prevention efforts, to treat as conservatively as possible, and to explain the potential consequences associated with antimicrobial treatment to animal owners and managers, including the possibility of promoting selection of resistant bacteria. However, the consequences of losing usefulness of an antimicrobial drug that is used as a last resort in humans or animals with resistant bacterial infections might be unacceptable from a public or population health perspective. Veterinarians could therefore face the difficult choice of treating animals with a drug that is less likely to be successful, possibly resulting in prolonged or exacerbated morbidity, to protect the good of society. The Committee recommends that voluntary actions be taken by the veterinary profession to promote conservative use of antimicrobial drugs to minimize the potential adverse effects on animal or human health. The veterinary profession must work to educate all veterinarians about issues related to conservative antimicrobial drug use and antimicrobial resistance so that each individual is better able to balance ethical obligations regarding the perceived benefit to their patients versus the perceived risk to public health. Specific means by which the veterinary profession can promote stewardship of this valuable resource are presented and discussed in this document.     

Accreditation of veterinary schools in Australia and New Zealand

Veterinary schools in Australia and New Zealand are assessed for accreditation purposes every six years by the Veterinary Schools Accreditation Advisory Committee (VSAAC), which is a standing committee of the Australasian Veterinary Boards Council (AVBC).1 Prior to undertaking an assessment, VSAAC requests a Self Evaluation Report from the school and subsequently spends a week on site to collect additional information. The committee also takes into consideration other quality assurance procedures within the university and aims for a process that complements other evaluation activities. Internal evaluation procedures within VSAAC are designed to reflect the process and outcomes of each visit and lead to annual revisions of the publication Policies, Procedures and Guidelines publication. The committee has close links with the Royal College of Veterinary Surgeons (RCVS), and there is a routine exchange of observers on all visits in the United Kingdom and Australasia. In recent years VSAAC has become increasingly interested in looking at ways to place greater emphasis on the outcomes of veterinary education and, eventually, to reduce our reliance on input measures. There has been good progress in identifying desirable attributes for veterinary graduates, but further work is needed to establish the reliability of assessment procedures. The Australasian accreditation system is very supportive of recent moves to achieve greater compatibility of veterinary accreditation systems in different parts of the world because we believe it has the potential to assist globalization of animal disease control and veterinary education.     

Ethical and evidential considerations on the use of novel therapies in veterinary practice

Novel therapies may be necessary both in the interests of the individual animal and in the advancement of veterinary science. However, special consideration is necessary to safeguard the welfare of the animals, ensure fully informed consent from the owner, determine the procedure's value in other cases and appropriately disseminate results. This article reviews ethical and evidential considerations raised when novel therapies are undertaken in veterinary practice, based on a series of committee meetings and intervening discussions held between members of the British Small Animal Veterinary Association Scientific Committee and Officers (2010–2011). The aim of this article is to encourage the advancement of novel veterinary therapies while safeguarding the welfare of animals.     

Providing high-quality research training for veterinary pathologists in Europe

Despite their key role in a wide range of fields relating to animal and public health, there is currently a lack of veterinary pathologists in Europe. In 1999, to help address the problem, the European College of Veterinary Pathologists (ECVP) and the European Society of Veterinary Pathology (ESVP) established a joint Education Committee. In this Special Article, Professor Anja Kipar and colleagues, all members of the committee, describe the ECVP/ESVP Summer Schools in Veterinary Pathology programme, which aims to provide high-quality research training for veterinary pathologists from all over Europe and beyond.     

Teaching veterinary parasitology: the North American perspective

The American Association of Veterinary Parasitologists (AAVP) initiated a study of parasitology curricula in veterinary schools in the US and Canada in November 1989. An ad hoc committee (Task Force) and then the Education Committee developed a position paper on teaching parasitology in veterinary colleges. In addition to confirming the importance of parasitology as a discipline they recommended a set of general learning objectives and proposed topic-specific titles rather than parasite-/group-specific titles. Another problem observed in teaching parasitology was a significant reduction in time available to teach parasitology. One way to compensate for the lost classroom time is to utilize some of the technological advances in presenting the material to students.     

Recommended guidelines for submission, trimming, margin evaluation, and reporting of tumor biopsy specimens in veterinary surgical pathology

Neoplastic diseases are typically diagnosed by biopsy and histopathological evaluation. The pathology report is key in determining prognosis, therapeutic decisions, and overall case management and therefore requires diagnostic accuracy, completeness, and clarity. Successful management relies on collaboration between clinical veterinarians, oncologists, and pathologists. To date there has been no standardized approach or guideline for the submission, trimming, margin evaluation, or reporting of neoplastic biopsy specimens in veterinary medicine. To address this issue, a committee consisting of veterinary pathologists and oncologists was established under the auspices of the American College of Veterinary Pathologists Oncology Committee. These consensus guidelines were subsequently reviewed and endorsed by a large international group of veterinary pathologists. These recommended guidelines are not mandated but rather exist to help clinicians and veterinary pathologists optimally handle neoplastic biopsy samples. Many of these guidelines represent the collective experience of the committee members and consensus group when assessing neoplastic lesions from veterinary patients but have not met the rigors of definitive scientific study and investigation. These questions of technique, analysis, and evaluation should be put through formal scrutiny in rigorous clinical studies in the near future so that more definitive guidelines can be derived.     

Conclusions and activities of previous expert groups: the Scientific Steering Committee of the EU

In 1998, the EU Commission consulted its Scientific Steering Committee (SSC) to give advice on actions against anti-microbial resistance based on scientific evidence. The SSC set up a working group and adopted in 1999 an Opinion on Antimicrobial Resistance. Statements given in the well-structured document are clear, and precise recommendations were proposed. Summarizing, the Committee stated: There is evidence to suppose a continuous flow of resistance genes between pathogenic and commensal bacteria and of transfer of these bacteria between different compartments of the biosphere, thus changing the genetic resources continuously. There exist numerous factors which influence the emergence and spread of anti-bacterial resistance. However, it is likely that restriction in the use of anti-microbials will lead to a containment or a reduction of the drug resistance problem. Actions should be taken promptly to reduce the overall use of anti-microbials in a balanced way in all areas: human medicine, veterinary medicine, animal production and plant protection.     

Standardized nomenclature of animal parasitic diseases (SNOAPAD)

An expert committee, appointed by the Executive Committee of the World Association for the Advancement of Veterinary Parasitology (W.A.A.V.P.), presents its proposal for uniform and proper terminology to denominate animal parasitic diseases or infections. In principle, the disease name is constructed solely by the suffix -osis, which is added to the stem of the name of the parasite taxon, formed from the nominative of the taxa. Standardized nomenclature of animal parasitic diseases (SNOAPAD) is meant as a guideline for general use, to improve the clarity of scientific communication. It should be especially useful in promoting effective usage of computerized data retrieval services.

New food safety initiatives in the Food and Drug Administration

Concern over the presence of veterinary drug residues in food has been increasing world wide. Because of this concern the Food and Drug Administration's Center for Veterinary Medicine (CVM) has been involved on an international basis in efforts to develop food safety standards for veterinary drugs. The major thrust of the Codex Committee on Residues of Veterinary Drugs in Foods (CC/RVDF) has been to achieve international agreement on veterinary drugs issues. CVM is an active participant on this committee. The CC/RVDF has established a list of priority veterinary drugs that are, or that have the potential to cause trade problems as the result of public health concerns. Included in this list are anabolic hormones, chloramphenicol, sulfonamides, nitrofurans, nitroimidazoles, somatotropins, benzimidazoles and trypanocides. In the upcoming years, the CC/RVDF will work toward developing international maximum residue levels for these compounds. The evaluation of the toxicity of veterinary drug-bound residues is another area of international concern. In conjunction with the Bureau of Veterinary Medicine, Health and Welfare Canada, CVM is developing guidelines on biological models to demonstrate the safety of veterinary drug-bound residues. In working with veterinary drug regulators from other countries, CVM has new solutions to human food safety problems.
