note = {Major aim of this thesis was to demonstrate how the use of a HACCP concept, a risk based approach, improves the sustainability of added value chains in European pig production. The thesis is featured as a pseudo-cumulative work with general introduction and conclusions and five independent chapters. Sustainability comprises nine themes. This thesis concentrates on animal health, meat quality and meat safety. 127 pig producing farms from five European countries and 15 different farming systems were investigated to design a catalogue proposing checklists for sustainability evaluation. This catalogue was used to assess farm specific risks in relation to animal health and meat safety, using principal component analysis. Only in the case of low risks due to diseases and failures of management, pig producing farms and the whole meat production chain can be categorized as sustainable. High intra- and inter-system differences of present risks were identified by this procedure. A combination of results from audits based on checklists and results from monitoring measures increase the certainty of risk assessment. A method for a continuous control and management of these sustainability aims was developed based on the principles of the HACCP concept. Unspecific and sensitive inflammatory markers take a key role regarding these monitoring measures. The innate immune system is affected by many factors like lesions, diseases, infections and permanent psychological stress and responds by increased concentrations of so called acute phase proteins. During a life cycle study with 99 pigs from rearing to slaughter, resulting in a data set of more than 18000 individual data records, these indicators of increased risks were investigated in detail. The correlation analyses of serum concentrations of these indicators measured at an age of 13 weeks presented the most significant coherences with parameters of meat and carcass quality. A direct coherence of the sustainability themes animal health and meat quality was proved for the first time. The risk of organ abnormalities was 16 times higher in cases of increased serum concentrations of one of these indicators measured directly before slaughter. The results proved these indicators in combination with further information to improve efficiency in terms of risk assessment and attendant measures. Implementation to practice was supported by the development of a rapid measurement method for the indicators based on a biosensor system.},
