Vermiculite has asbestos?

My favorite nursery told me today that it has stopped carrying vermiculite
because vermiculite has asbestos in it. The nursery is large and well-known
in the San Francisco-Berkeley area for its quality.

Can anyone shed light on this? I was just about to buy some vermiculite to
mix with the substrate in my new plant tank.
