[Immigration and work. Roles and opportunities for occupational medicine in the health and safety of migrant workers].

Background: It is estimated that in Italy there are 4 million migrant workers, accounting for about 10 percent of the total workforce. They contribute to national economic development but they are also heavily involved in the so-called "3D jobs" (dangerous, dirty and demanding/degrading).

Objectives: To draw occupational physicians' (OP) attention to the necessity of dealing with occupational health and safety problems related to migrant workers, highlighting his/her role and opportunities, in order to guarantee access to health services and prevent occupational health inequalities.

Methods: The available data on occupational diseases and accidents among migrant workers are discussed, as well as conditions of individual susceptibility; as an example, data are commented obtained in many years of health surveillance in a foundry.

Results: Migrant workers may suffer from occupational health inequalities. The OP, by means of focused risk assessment, health surveillance, fitness for work and health promotion, can substantially improve migrant workers' health. In fact, data from our experience showed how a migrant workforce may be well characterized and also represent an opportunity, instead of being a "risk factor".

Conclusions: Within the framework of needs for further methodological and applied research, the OP can play a proactive role in workplaces, aimed at real integration of migrant workers, with overall benefits for workers, enterprises and society.
