Eradicating slave labour by 2030: the challenge of worker health surveillance

Eradicating modern slavery is a relevant scientific, social, and institutional challenge issue. Indeed, efforts are being made globally to understand, map, and eradicate contemporary slavery as a target of the United Nations Sustainable Development Goals by 2030. However, little attention has been given to the Occupational Health Surveillance (VISAT) in the strategies and struggle against exploiting relationships. In order to fill this gap, the paper discusses contemporary slave labor (CSL) and its specificities in Brazil from an occupational health surveillance perspective. We initially highlight the link between CSL, occupational health, and occupational health surveillance (VISAT). We then present three VISAT challenges to addressing CSL: the challenging task of characterizing economic sectors and populations most affected; identifying determinants, risks, and effects on health; and strengthening occupational health practices and services to trigger specific actions regarding formation, information, and intervention in regions of high CSL prevalence. We conclude that Occupational Health Surveillance can play an essential role in the emancipation of workers engaged in slavery relationships.
