Intersectoral collaboration in a One Health approach: Lessons learned from a country-level simulation exercise

Intersectoral collaboration is an essential component of the One Health (OH) approach, which recognises the interconnectedness of the health of humans, animals, and the environment. The OH European Joint Programme (OHEJP) developed a national foodborne outbreak table-top simulation exercise (SimEx) to practice OH capacity and interoperability across the public health, animal health, and food safety sectors, improving OH preparedness for future disease outbreaks. The Portuguese OHEJP SimEx highlighted strengths and weaknesses regarding the roles and functions of available systems, the constraints of existing legislation, the importance of harmonisation and data sharing, and the creation of common main messages adapted to each target sector. However, there is still a long way to go to ensure cooperation among the Public Health, Animal Health, and Food Safety sectors, as a OH approach relies not only on the awareness of “field experts” but also on political and organisational willingness and commitment.
