[Monitoring and risk assessment of campylobacter infections].
The aim of a national study of a "Quantitative Risk Assessment of Campylobacter infections and broiler chicken" at the Federal Institute for Risk Assessment is to estimate the chicken meat associated risk of Campylobacteriosis in Germany by using probabilistic models. Furthermore, process parameters (modelling parameters) with the most vital impact on the risk of Campylobacteriosis due to chicken meat have to be elaborated to give recommendations for risk management options in the whole food chain. The outcome of Joint FAO/WHO Expert Consultations on Risk Assessment of Microbiological Hazards in Foods (JEMRA) with respect to Campylobacter spp. in broiler chickens are the baseline for the national approach. In addition, national studies from Canada, Denmark and The Netherlands have to be considered. Typical regional data with respect to the disease, to risk factors in Germany and to the qualitative and quantitative occurrence of Campylobacter in broiler chickens along the "farm-to-fork" continuum have to be collected and validated for elaboration of the four elements of a risk assessment. Data on the prevalence of the agent at different stages of the food chain given in available surveillance systems in Germany are limited with respect to their suitability as incoming parameters for the models. A monitoring programme, as required in the Directive 2003/99/EC on the monitoring of zoonoses and zoonotic agents, as well as coordinated programmes for the official food control authorities, could improve the data baseline for risk assessment studies for instance. To collect all necessary information on the quantitative load of Camylobacter in broiler chickens will go beyond the scope of any existing or future monitoring systems. Results can only be achieved by detailed studies. Beside this, regional data on production and processing of broiler chicken, consumption data and information on the behaviour of consumers in households when preparing broiler chicken products are relevant for assessing the final risk to the consumers. For some questions, especially with respect to the dose-response-relation, internationally used models have to be applied. The national study is embedded in a national epidemiological network of "Foodborne Infections in Germany" which is coordinated by the Robert-Koch-Institute and supported by the Federal Ministry of Education and Research (BMBF).
