A Harvard epidemiologist told a Missouri jury Monday that he has reached “medical and scientific certainty” that a woman’s daily use of Johnson & Johnson’s talcum powder products for four decades was the primary reason she developed ovarian tumors, according to Law360.
During the 10th day of the trial in St. Louis, plaintiff Lois Slemp called to the stand epidemiologist and gynecologist Dr. Daniel Cramer. Slemp’s is the fifth case over the alleged link between J&J’s talcum powder products and ovarian cancer to head to trial in the city. J&J’s talc supplier, Imerys Talc America Inc., is a co-defendant.
