The FDA has proposed a rule requiring manufacturers of talc-based baby powders and cosmetics to test for asbestos contamination. This move, mandated by Congress, addresses public health concerns as asbestos, a carcinogen, might contaminate talc during the mining process. Testing methods like polarized light and transmission electron microscopy are recommended, though companies can also use supplier certificates. This proposal stops short of banning talc products, a step advocated by groups like PIRG, amid ongoing litigation linking talc to cancer. Notably, Johnson & Johnson settled numerous lawsuits over its talcum products' safety.
