Lawyers alleging that Johnson & Johnson’s baby powder caused ovarian cancer have asked a judge to allow additional discovery in light of the “highly relevant” U.S. Food and Drug Administration’s test results last week that found some bottles had asbestos in them.

The FDA, as part of its investigation of cosmetic products, found that testing of a sample lot discovered asbestos in Johnson & Johnson’s baby powder. A second sample of a different lot tested negative for asbestos. Johnson & Johnson, which has denied that its talcum powder products contain asbestos, immediately announced a voluntary recall of 33,000 bottles of its baby powder in light of the FDA’s finding.
