The Talc Lawsuits
In the 1970s and 1980s, we gathered samples every hour from our talc processing facilities so that we could test it for asbestos. Samples of ground talc ore were combined and tested at least every month. Samples of this talc that was ready to be packaged were combined and tested at least every other week. And as an additional audit, every quarter, those samples were also tested again. There ...
