EFSA publishes guidelines for risk assessment of animal welfare

The European Food Safety Authority (EFSA) has published pioneering guidelines laying out, for the first time, a standardised methodology for the risk assessment A specialised field of applied science that involves reviewing scientific data and studies in order to evaluate risks associated with certain hazards. It involves four steps: hazard identification, hazard characterisation, exposure assessment and risk characterisation of animal welfare. The methodology, which follows a step-by-step approach, is designed to be applicable to all animal species A subdivision of the genus, a species is a group of closely related and similar-looking organisms; for example, in the case of Homo sapiens (humans), the second part of the name (sapiens) represents the species and all factors that affect animal welfare, including housing, transport, stunning and killing. The development of the guidelines supports EFSA’s commitment to ensure that all its work on animal welfare is underpinned by a strong scientific approach. They will be applied by EFSA’s Panel on Animal Health and Welfare (AHAW) to the future scientific advice it gives on risks associated with animal welfare. The guidelines support the implementation of the recently adopted EU Animal Welfare Strategy 2012-2015.

Philippe Vannier, Chair of EFSA’s AHAW Panel, commented: “These keenly anticipated guidelines will form an important part of the body of scientific literature on animal welfare and are made possible thanks to the dedication and experience of the EFSA scientists and external experts involved in their development. For the first time, scientists, veterinarians and all those with an interest in animal welfare are able to follow a practical, harmonised methodology to assess risks associated with welfare of farm animals.”

Risk assessment is a specialised field of applied science that involves the evaluation of risks associated with specific factors (or hazards). In the case of animal welfare, a factor is something that has the potential to impact on the animal’s welfare, such as the conditions that it is housed in, how it is transported from the farm to the slaughterhouse or the way in which it is killed. Until now, there have been no specific international guidelines on risk assessment for animal welfare meaning different approaches have been followed by scientific experts involved with this type of work.

The methodological framework proposed in the current Guidance document begins with problem formulation The process of defining the specific problem being addressed in, for example, an environmental risk assessment. It involves articulating a question and defining how it may be answered (e.g. by identifying the endpoints to be measured), an important process in which the risk assessor and risk manager work together to define the purpose, breadth and focus of the animal welfare risk assessment. After problem formulation, the risk assessment follows three key steps: exposure assessment One of the key steps in risk assessment, this relates to a thorough evaluation of who, or what, has been exposed to a hazard and a quantification of the amounts involved, in which the level and duration of exposure Concentration or amount of a particular substance that is taken in by an individual, population or ecosystem in a specific frequency over a certain amount of time to factors are defined; consequence characterisation, which describes what effect exposure to factors will have on welfare; and risk characterisation The final stage of risk assessment, in which the likelihood that a particular substance will cause harm is calculated in the light of the nature of the hazard and the extent to which people, animals, plants and/or the environment are exposed to it, which outlines the likelihood of occurrence The fact or frequency of something (e.g. a disease or deficiency in a population) happening and magnitude of adverse welfare effects, including any uncertainties and assumptions related to the risk assessment.

The Guidance document supports the scientific prioritisation of animal welfare issues by EFSA and, together with the Authority’s current work on the use of animal-based measures to assess the welfare of farm animals, will be useful in helping scientists, veterinarians and farmers to develop effective welfare controls and monitoring plans at farm level. In the future, the implementation of such welfare controls and monitoring plans should provide valuable feedback on the reliability of the risk assessment approach proposed in the Guidance, leading to further improvement of the proposed methodology.

The Guidance is also designed to complement the work of the European Commission in the area of animal welfare and comes soon after the launch of the new EU’s Animal Welfare Strategy 2012-2015. EFSA will present its recent work on animal welfare risk assessment at an international conference in Brussels (29 February - 1 March 2012) organised by the EC and the EU Danish presidency, entitled: “Implementing animal welfare through the new EU strategy: consumer empowerment and market opportunities”.
