Zoonoses are diseases that are transmissible from animals to humans directly or through ingestion of contaminated foodstuff. Since 2004, according to the former Directive 92/117/EEC, European Union member states submit zoonoses data using an online reporting system and a central data repository developed and maintained by the European Food Safety Agency (EFSA).

Data collected covers over eleven zoonotic agents and zoonoses that include salmonella, verotoxin producing E. coli, tuberculosis due to Mycobacterium bovis, trichinella, and rabies. The data entered is compiled and analyzed in a yearly Community Summary Report on trends and sources of zoonoses. Maps showing the distribution of zoonoses are an integral part of this report. Further, with the advent of ArcGIS Server technology and with the necessary confidentiality and data comparability precautions, the Web system offers a straightforward way to visualize and communicate the information, helping identify questions and hypotheses on the pattern and trends of diseases and their possible causes.

Besides the zoonoses data collection, EFSA investigates issues related to the origin and development of other epidemics, such as the Bluetongue virus in 2006. In this mandate, GIS tools and spatial analysis methods play a fundamental role.
