The objectives of the occupational disease surveillance program (MCP) are to estimate the prevalence rates of occupational diseases, describe the occupational exposure agents associated with these conditions, and contribute to the assessment of underreporting of occupational diseases. For the 2015–2016 period, 15 occupational physicians in the Lorraine region participated in at least one study session per year, representing 5.8% of the region’s occupational physicians each year. A total of 2,456 employees were examined during this period.
