An assessment of the strengths and weaknesses of current veterinary systems in the developing world

The changes that veterinary services have undergone in the developing world over the last two decades are expected to continue and result in the further privatisation of selected tasks, the decentralisation of decision-making and a move towards more focus on public goods service delivery by State veterinary units. At the same time, global food consumption patterns are changing in numerous ways, which will certainly affect veterinary services delivery systems. These changes include a trend towards increasing globalisation, rapidly escalating consumer demand for animal protein, intensification of livestock production into larger units and growth of the trade of livestock and livestock products. Intensification of livestock production into larger units and global trade will increase the challenges resulting from the resurgence of serious animal diseases, food safety hazards and veterinary public health-related problems. Facing and managing these challenges raises issues related to animal health delivery systems and national policies that will have to be addressed. Strengthening the capacity of State veterinary units to respond to regulatory responsibilities dictated by national laws and international World Trade Organization and OIE (World organisation for animal health) health standards will be at the centre of animal health policies in most developing countries. Creating an environment which facilitates privatised service delivery and supports subcontracting is likely to contribute to improving economic efficiency and providing wider access to veterinary services. Equally important is the issue of professional development, which must be addressed by refocusing veterinary curricula and improving professional standards. The profession will then be in a better position to serve the needs of increasing numbers of consumers.     

Alternative futures for world cereal and meat consumption.

Fundamental changes in the global structure of food demand will lead to an extraordinary increase in the importance of developing countries in global food markets. Economic growth in developing countries is changing consumption patterns, with slower growth (and in many countries actual declines) in per capita food consumption of grains and rapidly growing per capita and total meat consumption, combined with induced growth in cereal feed consumption. The present paper examines the hypothesis, suggested by some researchers, that high-meat diets in developed countries limit improvement in food security in developing countries. These analysts argue that reduced meat consumption in developed countries would release cereals from livestock feed to food for poorer populations, thus improving food security in developing countries. Using the International Food Policy Research Institute (Washington, DC, USA) global food projections model, the international model for policy analysis of agricultural commodities and trade (see Rosegrant et al. 1995), we first analyse the implications for future global cereal and meat supply and demand resulting from changes in global income, population growth and other structural changes, then simulate alternative scenarios to examine the effect of large reductions in meat consumption in developed countries on food consumption and food security in developing countries. The paper shows that while the long-term prospects for food supply, demand and trade indicate a strengthening of world cereal and livestock markets, the improvement in food security in the developing world will be slow, and changes in the dietary patterns in developed countries are not an effective route to improvement in food security in developing countries.     

Introduction: The provision of animal health services in a changing world

In the future, animal health services in developing countries will need to operate in a continuously changing policy, institutional and commercial environment. Firstly, the changing policies and priorities of national policy-makers regarding public and private sector roles, reinforced in Africa by the donors, have reduced funding and support for the large number of tasks that animal health services have traditionally performed, and there is continuing pressure from policy-makers to focus on what the public sector can do best. Secondly, poverty reduction has become one of the main criteria guiding the allocation of official development assistance, which has major implications for the main target clientele of veterinary services. Thirdly, population growth, increasing income and urbanisation are causing a marked increase in demand for livestock products in the developing world. As a result, the entire livestock commodity chain is undergoing major structural changes, which has significant implications for the definition and control of food safety standards. Fourthly, globalisation, and increasing trade and travel have greatly increased the risk of disease transmission between different countries and continents. Veterinary institutions in the developing world need to adapt to these challenges. They will have to be able to focus on the essential public sector roles. At the same time they must deliver those essential services to the poor, and provide the policy framework to ensure that the inevitable structural changes in the commodity chain take place in an equitable and sustainable fashion, with an acceptable level of health risk for the consumer. According to the weight given to these different objectives, changes in the institutional set-up need to be considered. This issue of the Scientific and Technical Review addresses these challenges. It begins by reviewing the basic economic characteristics underlying the provision of animal health services, and then examines the alternative delivery systems that are emerging in the developing world and their strengths and weaknesses. The implications for food safety and trade are specifically highlighted. Also included are the practical experiences of countries, from all along the development continuum, that have introduced alternative systems. This paper deals with implications for the future, and while the growing importance of veterinary care for companion animals is acknowledged, the focus is on veterinary services for food animals.     

The present and future organisation of Veterinary Services in Africa

In Africa, for many people, breeding animals is at the heart of their culture. For the poorest families animals play a vital role in most aspects of daily life, providing food, income and a place in society. Moreover, for poor farmers, livestock are the main source of energy, as they are used for farming and for the transport of their products. Unfortunately, trans-border animal diseases remain, to this day, one of the main obstacles to the development of breeding in Africa. They bring about heavy losses, direct and indirect, to national herds and often cause public health problems as well. Regional and international trade in animals and animal products is hampered due to these diseases, which are also one of the main causes of poor performance in the breeding sub-sector and of the growing gap between supply and demand of meat and milk. The challenge of maintaining sustainable and competitive growth in animal production requires major improvements in production methods and animal health. Better animal health protection in turn, depends on national policies which confer upon Veterinary Services the responsabilities and organisational structures they once had, but which unfortunately have been withdrawn by structural adjustment policies.     

Prevention of and attention to emergencies in South America

The authors review the policies designed to prevent and deal with animal health emergencies which have been implemented in countries of South America. They describe the evolution of the epidemiological situation of the continent, the new arrangements for international trade in animals and products of animal origin arising from the creation of the World Trade Organization (WTO), and the consequences of such developments for livestock production in South America. Veterinary systems used to prevent and deal with emergencies in the eleven OIE Member Countries on the continent are described, together with emerging problems which confront the Veterinary Services of the continent, namely: exotic diseases, abnormal occurrence of endemic diseases subject to control programmes, faults in food-safety mechanisms, diseases which have an environmental impact, and problems connected with animal welfare. The emergencies which present the greatest risk to South America are foot and mouth diseases, transmissible spongiform encephalopathies, the porcine reproductive and respiratory syndrome, food poisoning, Newcastle disease and fowl plague. Other problems are the appearance of new strains of existing agents, and the presence of resistant individuals among species of bacteria or harmful arthropods. The authors emphasise the need to co-ordinate the prevention of emergencies with development work at the international level, particularly regional and international agreements, harmonization of procedures, progress in animal health and public health, risk analysis, etc. These systems and methods of prevention have a contribution to make in enhancing the potential of animal production in South America, and the adoption of stricter health and quality standards, according to criteria established by the WTO Agreement on the Application of Sanitary and Phytosanitary Measures.     

Livestock producer participation in the control of epizootics in developed countries: the experience of France

Based on the French experience of animal health defence groups (groupements de défense sanitaire), the author highlights the importance, for both Veterinary Services and livestock producers, of livestock producer health organisations acting as partners of the Veterinary Services to complement the actions of private veterinarians. Charged with the task of providing livestock producers with information and raising awareness of the health regulations, these organisations offer key support to Veterinary Services in carrying out regulatory prophylactic measures, monitoring their execution, supplementing public compensation measures, and even being delegated to manage all or part of such prophylactic measures. By designing and implementing plans, with the support of private veterinarians, to combat or control epizootics which have an economic or trade impact, and by participating in or carrying out animal identification and offering health and environmental services, these organisations help to improve herd health and support the livestock producing industry. Growing demand, from both European Union applicant members and countries to the south, shows that although the French experience is not transposable, it can serve as a useful example.     

Animal welfare: the role and perspectives of the meat and livestock sector

Those in the livestock industry involved in rearing animals and in producing milk, meat and eggs, must respond to two demands: one expressed by consumers, and the other by the public. Regarding consumers, demand for food produced by the livestock industry has shown steady growth for a century. Over the last few decades, this growth has been sustained by the developing countries, and is based mainly on pig and poultry production, which provides cheaper products. Regarding the public, society is showing greater concern about the conditions in which livestock is reared, transported and slaughtered. The public demands not only that ill treatment of animals be fought against and penalised, but also that any unnecessary suffering should be avoided and even that animals should be guaranteed a certain degree of 'comfort'. Animal health, the most important aspect of their welfare, has vastly improved, as has the care of sick or injured animals. At the same time, the latest amenities used in livestock rearing, transport and slaughter are helping to eliminate situations involving extreme stress and suffering. Finally, the motivation of industry players and the safety of those who work with livestock must be taken into consideration. Training of personnel and the implementation of guides to good practice or of quality control do as much to improve animal welfare as do overzealous regulations.     

Economic development and its influences and risks for nutrition, cuisine and health

This paper reviews the evidence on some of the major trends in economic development at a global level and assess their influence on food, nutrition and health. Food and nutrition are themselves broad topics, and each is influenced by a myriad of local and international forces, making them both interesting and important, but also challenging in their complexity. It is especially difficult to deal with such a vast and complicated terrain in such a short paper, and one must inevitably deal only superficially with a number of complex areas. This paper will review a number of key forces for change in the global system, with a focus on the implications of each for food and nutrition. Each area is central to the experience of economic, social and political development, particularly in the period since 1945, and each is tied in various ways with that complex and interrelated set of changes that we call globalisation. Seven key factors will be explored: global population growth, leading to strong pressures on world availability of arable land and food; increasing integration in the global economy, as measured through such things as trade, financial flows and information exchanges, and with specific implications for the food industry and for trade in food products; growing gaps between rich and poor countries; similar increases in disparities between rich and poor segments within individual countries; the rapid growth of cities in the developing world, resulting in massive challenges for the food supply systems of many nations; the growth within some countries, for example in a number of Asian countries, of a "new middle class" with distinctive patterns of consumption; and, high levels of population movements between countries resulting in the creation of significant communities of immigrants in a number of nations. Examples will be drawn from the two regions familiar to the author, Asia and Sub-Saharan Africa, but with a particular emphasis on East Asia.     

Current and predicted trends in the production, consumption and trade of live animals and their products

Changes in livestock production, driven by both demand- and supply-side factors, have been significant worldwide. Though historically the developed world was a large supplier of meat and livestock for the developing world, the developing world has rapidly increased production and is meeting more of its growing domestic demand. Many regions of the developing world, however, do not produce enough currently to meet their domestic demand and continue to import more than they produce. There are exceptions, such as Brazil, Thailand, the People's Republic of China and India, where growth in livestock production has been rapid. It is anticipated that in the future many of the developing countries will increase domestic production to meet growing domestic demand. By 2030, beef will probably still be the most significant meat import of developing countries and milk will have more than doubled as a net export of the developed world.     

Synergies between veterinarians and para-professionals in the public and private sectors: organisational and institutional relationships that facilitate the process of privatising animal health services in developing countries

The delivery of veterinary services in most developing countries was, until recently, considered to be the responsibility of the public sector. However, over the past four decades, economic constraints and the imposition of structural adjustment policies (SAPs) have led to a gradual decline in public sector investment in real terms and thus a reduction in the quality and quantity of services available to livestock keepers. Many governments acknowledged that they were no longer able to provide services that were essentially of a 'private good' nature and introduced radical policy changes which sought to introduce the concepts of a market orientated approach towards agriculture and livestock production in particular. The role of government, in the future, would be to provide a reduced range of essential 'public good' services and to create a favourable environment in which the private sector could become established as a provider of 'private good' services and at the same time act as a partner in carrying out certain public functions under contract or 'sanitary mandates'. In almost all developing countries, however, these policy changes were not accompanied by appropriate development strategies. The reasons for this are complex. Firstly, SAPs may be considered to have been foisted upon governments by donors and are thus perceived by many policy-makers as the cause of financial problems, rather than a solution to them. Secondly, most animal health senior policy-makers in the public sector have been trained as veterinarians and lack the required management skills to plan change effectively. Furthermore, as regards clinical veterinary service delivery, especially in rural or more remote areas, the solution fostered by donor investment, which involves deregulation and the deployment of privately operating para-professionals, is often perceived as a threat to the veterinary profession and might result in limiting access to international markets for the trade of livestock and livestock products. An informal delivery system has gained a foothold in many developing countries in the absence of a well-planned strategy for the privatisation of animal health services. Most governments would now acknowledge that this presents a greater risk than the deployment of well-regulated and effectively supervised para-professionals. This paper explores some of the principal challenges facing policy-makers in their efforts to bridge the transition from full state provision of animal health services to the formation of a partnership with the private sector. Governments and donors need to take active steps to facilitate the process of privatisation of animal health services, especially those targeting the poorer rural subsistence and pastoralist farming systems. This would entail an initial investment in developing the necessary management skills at all levels in the delivery system. Thereafter, further investment would be required to allow the changes to be managed using tools such as the strategic planning cycle. Should sufficient resources be made available to allow the full participation of all stakeholders in the delivery of animal health services, appropriate institutions and effective organisational relationships addressing all the more important issues will have to be identified. The paper then proceeds to describe how different livestock production systems determine the level of demand for animal health services. If these services are to be provided on a financially sustainable basis, they must be tailored to meet actual rather than perceived demand. Identifying an appropriate model for animal health service delivery thus requires careful analysis of the production system to be targeted. Governments and donors can play a useful role in providing resources for this type of study as well as for appropriate market studies, business planning, training and access to soft loans. Finally, as regards regulation, as the law stands today, many activities currently practised by para-professionals are classified as 'acts of veterinary medicine or surgery' and may only legally be performed by qualified and registered veterinarians. The concept of 'principal' and 'subsidiary' legislation provides the necessary flexibility in the regulation of the delivery of animal health services to accommodate the rapid changes taking place in this environment today. Deregulation involves the delegation of responsibility for the performance of a defined range of veterinary interventions to para-professionals under the 'supervision' or 'direction' of a registered veterinarian. The author illustrates how the experiences of a number of projects in Tanzania were used to propose a definition of 'supervision' in law. The definition offers an opportunity to overcome the fear of compromising standards of delivery of animal health services through the deployment of para-professionals. In addition, such functioning provides employment opportunities for private veterinarians in rural areas where access to formal primary animal health services would otherwise be denied and may contribute to the process of quality assurance of national veterinary services in developing countries.     

Food industry and economic development in the Asia Pacific

The food industry in the Asia Pacific region is gigantic in size, and is therefore a key element in the economic development prospects for the region. It is estimated that in 2000, for example, total expenditure on food and beverages in China was worth $US 188.5 billion, second only to that in Japan at $322 billion. Yet it is clear that given the expansion of both populations and incomes in the region this market will expand rapidly over the next few years. Particularly important will be the continued growth of cities and of the share of employment in industrial and service activities. Much of this growth in food purchases will be supplied from local sources, but this will demand some fundamental changes in domestic food production systems. There will also be a substantial growth in the food trade, with ever increasing levels of national and regional specialisation. These developments will put increasing pressures on quality standards at all levels, with a growing emphasis on food safety, integrity, quality, and nutritional and health impacts. This paper reviews the current status of the food industry and the food trade in the region, and presents some projections for future developments. Particular emphasis is given to policy choices that must be made to ensure that the food system in the region develops in ways that are sustainable and most beneficial to the population as a whole.

The economic implications of greater global trade in livestock and livestock products.

The Uruguay Round of the General Agreement on Tariffs and Trade (GATT) established the World Trade Organization to supervise the reduction of barriers to, and liberalisation of, world trade. The application of sanitary and phytosanitary measures will be standardised to avoid use for protectionist purposes by countries or regional trade blocks. Harmonisation of animal disease control measures within regional blocks is essential if benefits to freer trade are to occur, but this harmonisation must be balanced against potential disease risks and costs associated with disease outbreaks. World trade in livestock products is concentrated among developed countries, although developing countries are responsible for approximately a third of poultry meat imports and exports. Despite liberalisation, the share of global trade by developing countries is unlikely to increase greatly in the short term. The benefits of trade and of freer trade are emphasised. Examples are given of the impacts of trade barriers on developing countries and of the harmonisation of European Union animal health standards. Economic implications for the future of greater global trade are assessed.     

Food safety in the 21st century.

The global importance of food safety is not fully appreciated by many public health authorities despite a constant increase in the prevalence of foodborne illness. Numerous devastating outbreaks of salmonellosis, cholera, enterohaemorrhagic Escherichia coli infections, hepatitis A and other diseases have occurred in both industrialized and developing countries. In addition, many of the re-emerging or newly recognized pathogens are foodborne or have the potential of being transmitted by food and/or drinking water. More foodborne pathogens can be expected because of changing production methods, processes, practices and habits. During the early 21st century, foodborne diseases can be expected to increase, especially in developing countries, in part because of environmental and demographic changes. These vary from climatic changes, changes in microbial and other ecological systems, to decreasing freshwater supplies. However, an even greater challenge to food safety will come from changes resulting directly in degradation of sanitation and the immediate human environment. These include the increased age of human populations, unplanned urbanization and migration and mass production of food due to population growth and changed food habits. Mass tourism and the huge international trade in food and feed is causing food and feedborne pathogens to spread transnationally. As new toxic agents are identified and new toxic effects recognized, the health and trade consequences of toxic chemicals in food will also have global implications. Meeting the huge challenge of food safety in the 21st century will require the application of new methods to identify, monitor and assess foodborne hazards. Both traditional and new technologies for assuring food safety should be improved and fully exploited. This needs to be done through legislative measures where suitable, but with much greater reliance on voluntary compliance and education of consumers and professional food handlers. This will be an important task for the primary health care system aiming at "health for all".     

Eastern Europe and the former Union of Soviet Socialist Republics: animal health systems in transition

The economic transition in Eastern Europe and the former Union of Soviet Socialist Republics (USSR) during the last decade has profoundly changed the agricultural sector and the well-being of people in rural areas. Farm ownership changed; selected farm assets, including livestock, were transferred to farm workers or others, and the social and service structures of rural society are in a state of uncertainty. The transition has, in general, led to the deterioration of rural services. Animal health services have also deteriorated. This decline is associated with the contraction of the livestock inventory, the fragmentation of farms, higher transaction costs for service providers, and the overall decline of the rural economy which has, so far, lowered the demand for animal health services. There are considerable differences in the way that these countries are coping with the economic transition and its aftermath. Among the determining factors in the former USSR are, as follows: the speed of recovery from the legacies of large State-controlled farming and a centrally planned animal health system, the efforts made to address poverty reduction, the choice on whether to become a Member of the World Trade Organization and the requirements of such membership, the ability to provide low-cost services to a fragmented and unskilled livestock production sector. In Eastern Europe, the requirements for joining the European Union (EU) are an additional and important determining factor. In the short term, the choice of a veterinary system to serve the livestock sector may differ from country to country, depending on the legacies of the past, the status of reforms and the proximity of Western markets. Lower-income countries with an oversupply of veterinarians may support labour-intensive, low-cost systems which focus on food security and public health. The better-endowed EU accession countries may focus rather on improved disease surveillance, production enhancement, quality assurance and increased food safety. Such choices may also determine the investment made by these countries in upgrading their State system, laboratories and veterinary education facilities.     

Veterinary vaccines and their use in developing countries

The burden of infectious diseases in livestock and other animals continues to be a major constraint to sustained agricultural development, food security, and participation of developing and in-transition countries in the economic benefits of international trade in livestock commodities. Targeted measures must be instituted in those countries to reduce the occurrence of infectious diseases. Quality veterinary vaccines used strategically can and should be part of government sanctioned-programmes. Vaccination campaigns must be part of comprehensive disease control programmes, which, in the case of transboundary animal diseases, require a regional approach if they are to be successful. This paper focuses on the salient transboundary animal diseases and examines current vaccine use, promising vaccine research, innovative technologies that can be applied in countries in some important developing regions of the world, and the role of public/private partnerships.     

The global diet: trade and novel infections

Practices designed to meet the demands of global trade can amplify food safety problems. Ever-increasing pressure to churn out more product and better sides of beef has generated processes that compromise existing safety measures. Among the concerns are intensified food production, use of antimicrobials and hormones as growth promoters, and poor sanitary infrastructure in some food producing countries. Accompanying the innovations designed to serve the diversifying global palate are emerging and re-emerging infectious diseases, or "trade-related infections." The joint efforts of international public health and industry are required to effectively address these growing health challenges.     

Unapparent foot and mouth disease infection (sub-clinical infections and carriers): implications for control

Unlike animals which are carriers of foot and mouth disease (FMD), sub-clinically infected animals may be highly contagious. The implications of sub-clinical infections for the control of FMD are serious because such animals are likely to disseminate the disease when in contact with susceptible livestock. Recent dissemination of FMD virus (FMDV) in Europe shows that sub-clinically infected animals render trade in animals or animal products a potential risk for importing countries. This clearly demonstrates that the paradigm 'free of FMD without vaccination' is not synonymous with 'risk-free'. The risk of introduction of subclinical FMD into FMD-free countries may increase significantly, with the occurrence of large susceptible animal populations, changed agricultural practices, expansion of trade in live animals and animal movements, increased trade in animal products and greater mobility of people. Such changes in circumstances require that national and international authorities remain continuously vigilant to determine any altered risk for importation of FMD. A few historical reports and some recent observations in southern Africa indicate the possibility of dissemination of FMD by bovine carriers into herds of susceptible cattle. These reports have greatly influenced FMD trade policies and thus, FMD control and eradication strategies. However, other field evidence does not support this claim and several controlled experiments were unable to show that carriers are able to initiate disease. When millions of cattle were systematically vaccinated with good quality vaccines, FMD disappeared in spite of a large sentinel population in the form of calves and unvaccinated sheep and pigs. A low number of carriers most likely persisted, but they did not hamper the eradication of the disease. Vaccination policies and trade regulation must be based on risk assessments taking these factors into consideration.     

The organisation and functioning of Veterinary Services: results of a 2005 survey of Member Countries of the World Organisation for Animal Health

A questionnaire was sent to the 167 Member Countries of the World Organisation for Animal Health (OIE) in 2004 and 2005. The organisation and functioning of national Veterinary Services were analysed based on the responses from 85 of these countries. Leaving aside variations between countries, Veterinary Services are very involved in animal health and food safety controls at farm level (including animal feed), and during primary and secondary processing, whether alone or in conjunction with other services. At the lower end of the chain, namely distribution and the food service industry, responsibilities tend to be more widely shared. Veterinary Services have a central responsibility in international trade in animals and animal products. The main weaknesses in the chain of controls concern the logistical and financial resources of Veterinary Services, and insufficient involvement of livestock producers and even of field veterinarians. The many recent reforms are tending to provide a more consistent, integrated approach to animal health and food safety controls 'from the stable to the table'.     

我国布鲁氏菌病防控现状、进展及建议

布鲁氏菌病（布病）是一种易被忽视的人畜共患病。不仅严重危害人民身体健康,而且也严重影响畜牧业、旅游业、国际贸易的发展,还会带来食品安全隐患。在过去的20年里,人类和动物布病的防控已经取得了较大进展。与此同时,特别是在发展中国家,控制和根除布病仍然面临巨大的挑战。近年来,随着我国家畜饲养量不断增加,动物及其产品流通频繁,人畜接触机会增加,布病流行范围也不断扩大。全国布病疫情相对集中在内蒙古及其毗邻省份,其原因比较复杂,与畜牧经济发展、历史疫区活跃、传染源的流动及对布病重视程度等诸多因素都有很大关系。本文将重点介绍布病在中国的防控工作历程、监测情况和防治现状,并提出防控建议。
