Microorganisms by far are representing the most important cause for food safety risks. Sources of food contamination are given along the whole food chain. The most frequent causative agents of food infections, Salmonella and Campylobacter, mostly can be found in the animals herds. A real improvement of the situation can only be reached by a strong inclusion of the agricultural area in the programs for repressing the pathogens. Problems in animal health and premortal stress of the slaughter animals cause considerable bacterial translocation processes and increase the consumer risks. Only few publications exist on the influence of the animal farming systems on the development of microbial food risks. The consumer accepts only animal management systems, which meet the demands for animal welfare, economical efficiency and especially the demand for product safety. 相似文献

Space allowance for animals in transit is a consistent concern in many countries that are developing codes of practice and regulations to assure humane treatment of food producing animals. The minimum space allowance requirements for a broad size range of swine in transit has not been well described or scientifically substantiated. A maximal loading pressure recommendation for pigs weighing from 5 to 250 kg was derived by a consultative process involving the swine transportation industry, animal welfare groups, and a literature review. The recommended maximal loading pressure under ideal conditions for swine loaded in groups can be described as a hoerl model y = (37.53)(0.9969)w(W0.5008), where y = loading pressure in kg body weight/m2 and W = average animal body weight in kilograms. 相似文献

According to the Animal Protection Law (1986) fish are to be killed by methods which do not cause pain. However, the regulations do not cover the killing of non-food fish. A questionnaire, conducted among 85 fish scientists, revealed that single fish should be killed by a blow on the head, and larger numbers by electrical methods or by use of chemicals. Decapitation was proposed for eels. A regulation from 1936 stipulates the methods for the slaughtering of food fish. Mechanical or electrical stunning is compulsory except for eel and flatfish. The questionnaire showed that in general the present legal regulations are sufficient for the slaughtering of fish with the exception of eels. The commercially available apparatus for stunning and killing do not always fulfill the requirements of animal protection, slaughtering technology and safety for the user. Official testing of these apparatus as well as the evaluation of new methods--like CO2-stunning--are necessary in order to prevent the use of methods which are feasible, but do not fulfill animal welfare, especially for eel. 相似文献

Before its broad application in practice, housing equipment should be tested, in particular with regard to animal welfare. The differing positions of the German Federal Council (Bundesrat) and the German Federal Parliament (Bundestag), whether such testing should be mandatory or voluntary, have been conciliated in the amended animal welfare act by empowering the Federal Ministry of Food, Agriculture and Fisheries (BML) to fix official standards for voluntary testing procedures by regulation. On request of the BML, a report as scientific basis for a draft regulation is currently prepared by the scientific animal welfare committee of the German Agricultural Society (DLG). The scientific animal welfare committee has been appointed by the DLG in order to provide support in the effort to strengthen animal welfare aspects in the DLG-utility testing procedure of housing equipment, which is in place since 1953. The committee elaborates standards concerning testing methods, assessment criteria and the necessary size of investigations. As required, the scientific animal welfare committee may support the DLG-testing bodies in the implementation of the animal welfare part of the testing procedure. It will, moreover, be involved in the welfare assessment based on the testing results. The amendments of the already established testing procedure will help to fulfill the general requirements on an acceptable animal welfare testing procedure. While keeping in mind that there are certain limits in what can be achieved by a voluntary testing procedure, the enhanced consideration of animal welfare aspects within the DLG-utility testing procedure has the advantage to be relatively unbureaucratic and in line with EU legislation, and is, therefore, an appropriate tool for a contibrution to improved animal welfare in livestock housing. 相似文献

Protection of farmed camels (Camelus Dromedarius): Welfare problems and legislative perspective 
下载免费PDF全文
下载免费PDF全文 In the last years animal welfare has assumed an increasing interest in our society, influencing legislation to enact many provisions aimed at the protection of animals. Along with increased consumer awareness of the need to maintain ethically acceptable conditions of raised animals, scientists too have begun to investigate the conditions of animal welfare, the tools for its evaluation and for its improvement. Although there are many advances in knowledge, much remains to be investigated concerning many species considered "minor", that is, camels and dromedaries. Dromedaries, recently, have attracted the interest of some breeders following the results of studies concerning the nutritional and therapeutic properties of their products ‐ milk in particular ‐ that make them ideal for some particular categories of consumers, such as diabetics, obesity sufferers, lactose‐intolerant subjects, menopausal women and so on. Considering their use in dairy husbandry, dromedaries are reared under intensive and/or semi‐intensive systems with the resulting emergence of specific needs, which should be fulfilled in order to have appropriate welfare. This paper's purpose is to give practical elements in order to find out dromedary welfare standards, promoting a comprehensive set of regulations on welfare, care and protection of this animal. 相似文献

Colleges and universities have an obligation to teach the basis of animal husbandry and welfare and must prepare students so that they can respond effectively to challenges by proponents of the animal welfare and animal rights movements. Veterinary curricula must now contain formal instruction in professional ethics and humane stewardship of animals for accreditation by the American Veterinary Medical Association. It is helpful if students have an understanding of farm animal behavior, stress physiology and methods of assessing welfare prior to learning about the animal welfare/rights movement's philosophies and issues. A review of early judicial practices, "classical" Judeo-Christian philosophy, the philosophy of Rene Descartes, Jeremy Bentham, Albert Schweitzer, and current philosophers and the entertainment media places the movements in perspective. Students should be familiar with such concepts as the mind-body controversy, equality of suffering, self-awareness or intelligence, and speciesism. After acquiring an appreciation of the basics, a knowledge of the issues facing animal agriculture and the arguments for and against each issue are necessary. Graduates of colleges of agriculture need to realize the potential effects the movements can have and take the initiative to improve the image of animal agriculture. 相似文献

OBJECTIVE: To examine attitudes toward farm animal welfare among veterinary college faculty. DESIGN: E-mail survey. STUDY POPULATION: 157 US veterinary college faculty with large animal or food animal emphasis. PROCEDURE: Veterinarians from 27 US veterinary colleges were contacted via e-mail and asked to complete a 7-page survey relating to farm animal welfare issues. Thirty-one percent of those contacted responded. RESULTS: 71% of respondents self-characterized their attitude toward farm animal welfare as "we can use animals for the greater human good but have an obligation to provide for the majority of the animals' physiologic and behavioral needs." An additional 19% of respondents were more concerned about animal welfare than was indicated by that statement, and 10% were less concerned about farm animal welfare than was indicated by that statement. Significant relationships among demographic variables and attitude scores were observed, including more concerned attitudes among females, those with more liberal political views, and those who cited lower religiosity. No relationship between attitude and age was observed. CONCLUSIONS AND CLINICAL RELEVANCE: Veterinary college faculty have the opportunity to impact many stakeholders within the animal agriculture industries (eg, future veterinarians and policy makers looking for a veterinary science perspective). Results indicated that a considerable level of concern toward farm animal welfare is present in this population. Although the process of change may not be rapid, it is likely that the influence of these respondents will factor heavily into enhancing farm animal welfare. 相似文献

In this study the animal welfare legislation and three private standards in Sweden, focusing on dairy cows, were analysed. The aim was to investigate to what extent these regulations consisted of resource-, management- or animal-based requirements, to analyse the content and discuss consequences. The results showed a higher proportion of management- and resource-based requirements than animal-based in all regulations. However, the borders between these categories were not as distinct as expected. The private standards put slightly more emphasis on the animal-based requirements and on animal welfare at herd level. It was primarily the organic standard that included higher animal welfare demands than the legislation. Due to vague wording and guideline statements it was not always clear if the welfare level achieved would be the same in practice although the requirements were similar. It will be necessary to clearly distinguish between requirements and measures to make the policy process more transparent. 相似文献

The reduction of the entry of pathogens in the food chain is an important premise in improving the safety of food of animal origin. Since food animals are the main reservoir for pathogens, the prevalence of pathogens in livestock is of great importance. Unfortunately, classical measures to improve animal health can not exclude the presence of the main food-borne zoonotic agents (Salmonella, Campylobacter, Listeria monocytogenes, verotoxinogene Escherichia coli, Toxoplasma gondii) in "clinically healthy" animals. Absence of pathogens in livestock must be regarded as an unrealistic aim. To achieve an effective improval of product safety through logistical, hygienic or technological measures both farmers and food producers need valid data about the prevalence of pathogens in livestock, in each animal and in raw material of animal origin, respectively. Yet available data are insufficient. New European directives and regulations concerning monitoring and control of zoonosis demand the systematic control of presence of zoonotic agents in livestock and later steps of the food chain. 相似文献

Every slaughter process involves problems as to animal welfare as well as safety aspects and the protection of workers. With poultry these are basically concentrated on electrical stunning. Electrical currents and voltages suitable for stunning slaughter animals are principally also hazardous for man in what respect body resistance is of crucial importance. Potential hazards have to be looked upon as present in spite of existing safety regulations. Comparatively high stunning voltages for poultry recently proposed because of animal welfare considerations have met objections not only from the viewpoint of meat hygienic but workers' safety regulations as well. While the former meanwhile could be overcome the latter still has to be investigated, especially as a regulation on the electrical stunning of poultry is currently being prepared. In this respect the question whether adequate stunning efficiency can be obtained by reducing the voltage and prolonging the time of exposure is of special interest. First preliminary results of such investigations are presented. To ensure workers' safety other related aspects should also be taken into account and examined for improvements. 相似文献

As of 1 September, 2001 existing legislation regulating outdoor dog husbandry is replaced by the domestic dog welfare directive of 2 May, 2001. The new directive applies to details of housing and breeding of dogs kept indoors and as domestic companions. Thus, minimum requirements for housing, care and feeding now apply to the great majority of private dog owners. However these requirements do not apply to animals in transit, in individual veterinary treatment or to those used for scientific experimentation whose goals justify deviations from these standards. Additional regulations apply to dog breeding and showing. Puppies may not be separated from their mother and litter before eight weeks of age. "Prohibition of breeding for aggressiveness" cited in Paragraph 11b of the animal welfare law is defined, and includes various breeds and hybrids. The directive includes an index for the care and treatment of dogs by commercial breeders. After a transitional period no dogs which have been subjected to amputations at the expense of the animal's welfare in order to achieve specific features may be shown publicly. The author provides critical commentary on the regulations of the domestic dog welfare directive and points out areas which will continue to be of concern. 相似文献

Veterinary surgeons are required to assess an animal's welfare in a range of different circumstances in the course of their daily work. These assessments may relate to the long‐term welfare of an individual animal under their care, or the current welfare of a population of animals that are unfamiliar to them as individuals. The welfare assessment made may subsequently have implications for the treatment that an animal receives or for the decision of whether or not an animal should remain in its current home. Yet welfare assessment is not straightforward. Here we review the challenges that welfare assessment presents and review the tools currently available to meet them. Lastly, we look towards the future of equine welfare assessment, with examples of current research to develop tools and optimise welfare assessment. 相似文献

The general concept of animal welfare embraces a continuum between negative/bad welfare and positive/good welfare. Early approaches to defining animal welfare were mainly based on the exclusion of negative states, neglecting the fact that during evolution animals optimised their ability to interact with and adapt to their environment(s). An animal's welfare status might best be represented by the adaptive value of the individual's interaction with a given environmental setting but this dynamic welfare concept has significant implications for practical welfare assessments. Animal welfare issues cannot simply be addressed by means of objective biological measurements of an animal's welfare status under certain circumstances. In practice, interpretation of welfare status and its translation into the active management of perceived welfare issues are both strongly influenced by context and, especially, by cultural and societal values. In assessing whether or not a given welfare status is morally acceptable, animal welfare scientists must be aware that scientifically based, operational definitions of animal welfare will necessarily be influenced strongly by a given society's moral understanding. 相似文献

Veterinarians play a pivotal role in public health control, in particular in the management of risks deriving from pharmacological treatments of food-producing animals. Veterinary medicinal products can represent a risk for animal health and welfare (side effects, decreased efficacy), for farmers and practitioners administering the drug, for consumers of food of animal origin (presence of residues, occurrence of antibiotic resistance) and for the environment. According to pending European guidelines, risk management starts from marketing authorisation that must be based on risk evaluation and can be denied when the risk/benefit ratio is not favourable considering the advantages for animal health and welfare and for safety of consumers. Veterinarians can prevent and control risks by using correct pharmacological criteria to choose and administer medicinal products and undertaking risk-based inspection of residues of drugs in food of animal origin. Moreover, a major tool for veterinarians to prevent and control drug-borne risk is "pharmacovigilance". Risks for the environment are usually assessed during the pre-marketing approval process, however veterinarians, as risk managers, should educate farmers about correct drug handling and disposal, and periodically verify that suggested measures are applied. 相似文献

As a complement to the concentration on negative states in welfare science, scientists are increasingly considering the desirability of measuring positive outcomes. Since evaluation of an animal's mental state is a critical goal for welfare assessment, considerations of both positive feelings (what an animal "likes") and resources that an animal is motivated to obtain (what an animal "wants") appear to be important. However, since animals may make choices that are not in their long-term interests, an assessment of positive feelings and resources should include an evaluation of any associated actual or potential harms, such as fear, distress, pain, injury and disease. A review of current evidence suggests that positive welfare can be best assessed by evaluation of resources (i.e. inputs) that are valued by an animal and by positive outcomes such as behavioural responses, influences on cognitive processes and physiological markers. Since negative welfare is often inversely correlated with positive welfare measures, current welfare policy will have been achieving some positive welfare outcomes, however the explicit inclusion of positive welfare outcomes in the framework allows for analyses that are both deeper and more in tune with commonsense, which can hopefully yield more objective policies. 相似文献

Recently, eel recirculation systems have provoked increasing attention in intensive fish culture, especially concerning animal welfare. "Aquaculture", "Intensive Culture", and "Recirculation Systems" are often confused with each other. This study, first of all, differentiates among these terms. The economic relevance of aquaculture in the Federal Republic of Germany is demonstrated by figures. A tendency towards intensive methods can only be seen in trout and eel culture. The problems of recirculation systems are explained comprehensively. Particular emphasis is laid on the conflict between theoretical suitability of intensive fish production and the absence of commercially working systems. At present, intensive fish culture does not pose a serious animal welfare problem in Germany. However, it is necessary to define the biological requirements of fish concerning their optimal accommodation in aquaculture facilities. According to the Law for the Protection of Animals, these requirements have to be laid down in an ordinance. Only then control is possible as to whether aquaculture systems fulfill fish welfare demands. 相似文献

Quality management on dairy farms becomes more and more important regarding the different areas of animal health, animal welfare and food safety. Monitoring animals, farm conditions and farm records can be extended with risk identification and risk management. The hazard analysis critical control point's system is useful as an on farm strategy to control the product as well as the production process on the areas of animal health, animal welfare and food safety. This article deals in detail with the question how to develop a qualitative method where risk can be defined as an interaction between probability and impact. Two parts of the production process (milk harvest and treatment of cows) where used as an example how to apply the hazard analysis critical control point's system on chemical, physical and microbiological contaminants of milk. Not just only by summarizing the different critical checkpoints for each area but also by giving them a precise judgement of probability and impact. 相似文献

Animal production is relevant with respect to farm income and the position of the sector in the market, but also with respect to the quality and safety of products of animal origin, related to public health. Animal production is part of a chain of food production. Therefore, producers have to take consumer expectations and demands in the domains of animal health, welfare and environment into account. A different attitude for production has to be adopted; this attitude can be visualized in good farming practice, GFP, codes. Farmers who focused on quality in its broadest sense need a system supporting them in their management and control of quality risks. Generally speaking, there are three systems for that purpose: GFP, ISO and HACCP. When the hypothesis followed relates to animal health being a feature of quality, or else welfare and environmental issues, then animal health care can be executed following quality control principles. The HACCP concept is well suited for quality control at farm level, involving risk identification and risk management. The on-farm monitoring and surveillance system of critical control points in the animal production process is the most important tool in this procedure. Principles for HACCP application as well as certification fitness of HACCP are elaborated upon. They are illustrated by using salmonellosis in meat-pig farms as objective for an HACCP approach. It is further discussed that, in addition to animal health and quality, animal welfare and environmental issues could also be covered by an HACCP-like system in an integrated manner. Ultimately, the HACCP modules could end up in an overall ISO certification. 相似文献
