I think the problem wasn't the talc itself, but that it was contaminated with asbestos in the process of mining the talc and turning it into talcum powder.

So presumably it's been addressed through closer monitoring, but the article does say that they plan to phase out talcum powder worldwide and replace it with cornstarch powder.

Edit: Apparently there are some studies which suggest talc itself could also be carcinogenic. I suppose this may be one reason why the issue is so confusing, because it's really 2 issues in one: a) whether talc that's sold is contaminated with asbestos, and b) whether talc itself is carcinogenic.
