Studies of Miners & Millers

Studies of thousands of people who were exposed to talc on a daily basis—through their work mining and milling talc powder, show that none developed mesothelioma. In 1976, scientists initiated a study of miners and millers of an Italian cosmetic talc mine used by Johnson & Johnson. This study compared those workers employed between 1921 to 1950 to a population from a nearby town of Alba, Italy. That study found zero cases of mesothelioma.

In 1979, the scientists updated the study using new statistical data, and compared the miners and millers who worked between 1946 to 1974 to national Italian population data. Still, zero miners and millers developed mesothelioma. This study was updated again in 2003, then in 2017, and continues to demonstrate that none of the miners or millers developed mesothelioma.

Similar studies of miners and millers have been conducted on other cosmetic talc mining operations. A study of Vermont miners and millers conducted by NIOSH and OSHA concluded that none of the miners and millers developed mesothelioma. Studies of miners and millers who worked in cosmetic talc deposits in Norway, Austria and France also show that none of those talc workers developed mesothelioma.
