A Reuters investigation in December 2018 revealed that from at least 1971 to the early 2000s, Johnson & Johnson's talc and finished powders tested positive for asbestos. Traces were first detected in the late 1950s. J&J didn't tell the FDA that at least three tests from 1972 to 1975 found asbestos — one at levels reported as 'rather high.' Company executives, mine managers, scientists, doctors, and lawyers all knew about the contamination. They also successfully influenced regulators' plans to limit asbestos in cosmetic talc. J&J stock dropped 10% on the news — its worst loss in two decades.
