In the past decade, asbestos has been found in common, supposedly non-toxic children's products: everything from crayons, to sidewalk chalk, to modeling clay. Companies frequently claim that their products have been tested and conform to their legal requirements of child safety, but asbestos testing is not even required and therefore often left out.

The Art & Creative Materials Institute, Inc. (ACMI), which is responsible for certifying creative materials non-toxic (AP certification), claims to test for all possible human health hazards, but given the reports that have been released in the past decade, in which even AP certified crayons, in 2000, tested positive for asbestos, it seems that some hazards escape ACMI's notice.
