9 potential and limitations of husbandary practice to secure animal health and welfare and food quality Foreword Sustaining Animal Health and Food Safety in Organic farming (SAFO) is an European Commission funded project, with the objective to contribute to improved animal health and food safety in Organic livestock production systems in existing and candidate member countries of the European Union. Workshops form a central part of the SAFO activities. This volume, with the contributions to the 2nd SAFO Workshop in Witzenhausen, Germany in March 2004, is one in a series of five proceedings published during the lifetime of the project (2003-2006).

10 Electronic version of the proceedings will also be available at the SAFO web-site at The 2nd SAFO workshop focussed on the impact of farm level practices on animal health and quality aspects of Organic livestock production. While most farm assurance schemes, including the Organic farming certification, are primarily concerned with regulating the production system, the outcomes of the system, in terms of animal health and welfare, are particularly important in livestock production. The status quo assessments presented in the Workshop suggested that animal health and welfare outcomes of the Organic production systems do not necessarily fulfil high consumer or indeed animal expectations.
