The report comes as the company faces thousands of lawsuits claiming that its talc products caused cancer.
Reuters reviewed Johnson & Johnson documents produced as part of the trials, many of which had been shielded from view by court orders.
The documents revealed that from at least 1971 to the early 2000s the firm’s internal tests sometimes found small amounts of asbestos in its raw talc and finished powders.
Most of the firm’s tests did not find asbestos, and it did not disclose the tests that did to regulators, Reuters found.
Mr Bicks said the tests cited by Reuters article were “outlier” results. In court, the firm has argued that some of the documents referred to industrial talc products.
The investor reaction wiped 10% off the firm’s market value at one point, making it the biggest loser on the Dow.
Legal cases against Johnson & Johnson have had mixed results.
In July, Johnson & Johnson was ordered to pay $4.7bn (£3.6bn) in damages to 22 women who alleged that its talc products caused them to develop ovarian cancer.
The verdict marked the largest payout the firm has faced over the allegations. The firm is appealing against the decision.
