The occupational disease surveillance program (MCP) relies on a sentinel network of volunteer occupational health teams, which report twice a year—during two consecutive two-week periods known as "Quinzaines"—all cases of occupational diseases observed during their consultations and the associated occupational exposure agents. This survey ensures the anonymity of employees who seek consultation and of the companies involved. In Nouvelle-Aquitaine, the occupational health and safety services involved are those of the general social security system (inter-company and independent services), the agricultural social security system (MSA), and the civil service. This brochure presents the results of the 2022 Quinzaines in the Nouvelle-Aquitaine region.
