UPDATE 1-U.S. jury rules against Bayer in Roundup cancer case

A U.S. jury on Tuesday found Bayer AG's glyphosate-based weed killer to be a "substantial factor" in causing a man's non-Hodgkin's lymphoma, allowing the trial to proceed into a second phase on liability and damages. The jury in San Francisco federal court in a unanimous ruling found Roundup, one of the world's most widely-used weed killers, to be responsible for the cancer of California resident Edwin Hardeman.

The case will proceed into a second trial phase before the same jury on Wednesday to determine Bayer's liability and potential damages. During that phase, Hardeman's lawyers can present evidence allegedly showing the company's efforts to influence scientists, regulators and the public about the safety of its products. Bayer did not immediately respond to a request for comment on Tuesday. (Reporting by Jim Christie in San Francisco; Additional reporting and writing by Tina Bellon in New York Editing by Bill Berkrot)
