A salmonella data bank for routine surveillance and research.

A salmonella data bank has been established in the State of Brandenburg, Germany, with due steps being taken to ensure the protection of personal data. The system of data collection and rapid return of information to the local health and veterinary services have become essential elements in intersectoral cooperation in case investigation, disease prevention, and epidemiological research. A number of issues, particularly those concerning the pathways of infection, characteristics of clusters of cases, and the infection of different population strata can now be examined and monitored. An important feature of the data bank is its accessibility by local as well as central state services using a PC-based program and the wide interdisciplinary circulation of regular reports. Preliminary results on the data volume, age distribution of cases, and salmonella isolation rates in different population strata are presented. The data bank supports studies on marketing and purchasing patterns of agricultural products representing potential vehicles of infection, and it should encourage investigations to trace the reservoirs of infection and contamination points along the food chain.
