Foodborne illness due to Campylobacter is a widespread problem in all Nordic countries, and the Committee of Senior Officials under the Nordic Council has during the last years supported several projects related to this problem. Managing the problem requires a cooperation between people with different backgrounds and skills. In this respect, the organisation of workshops with plenty of room for discussions and interaction is useful to summarize the state of the art within a field, to exchange experiences, to create networks and to seed ideas for future work. In the fall of 2003, a workshop was held in Reykjavik with emphasis on risk management issues relating to Campylobacter. The present workshop was held in Uppsala 12-13 April 2005 and was focused on risk assessment and epidemiology issues in view of recent scientific studies and developments in the different Nordic Campylobacter Control Programs.
