Malignant mesothelioma is associated with occupational and environmental asbestos exposure through inhalation.
Occupational exposures to asbestos fibers occurs in a variety of industrial operations, including mining and milling, manufacturing, shipbuilding and repair, and construction.
Asbestos awareness training is required upon initial assignment and annually for employees whose are exposed to airborne concentrations of asbestos at or above the permissible exposure limit (PEL) and/or excursion limit.
OSHA requires a minimum of 2 hours training annually.
Malignant Mesothelioma Mortality — United States, 1999–2015
During 1999–2015, a total of 45,221 malignant mesothelioma deaths were reported, increasing from 2,479 (1999) to 2,597 (2015). Mesothelioma deaths increased for persons aged ≥85 years, for both sexes, persons of white, black and Asian or Pacific Islander race, and all ethnic groups. Continuing occurrence of malignant mesothelioma deaths in persons aged <55 years suggests ongoing inhalation exposure to asbestos fibers and possibly other causative EMPs.
What are the implications for public health practice?
Despite regulatory actions and decline in asbestos use, the annual number of malignant mesothelioma deaths remains substantial. Contrary to past projections, the number of malignant mesothelioma deaths has been increasing. The continuing occurrence of mesothelioma deaths, particularly among younger populations, underscores the need for maintaining efforts to prevent exposure and for ongoing surveillance to monitor temporal trends.
